What is it Going to COST to BUILD a Kit CATAMARAN? – A Comprehensive Guide (MJ Sailing)

The big question on everyone’s mind is … what is it going to COST us to build this new catamaran?

Matt has spent the past few weeks talking to the designers at Schionning and Oram, as well as professional and ameture builders to gather as much information as possible on the costs that go into building a kit catamaran. Things can obviously vary from builder to builder, but taking a simple and basic approach, we’ve narrowed down the numbers on what we estimate it will cost to build an Oram 45R.

To take a look at the full design specs, take a look here: https://www.boboramdesign.com/45r

After discussing previous builds with the many others who’ve come before us, we found out there is one small thing that can skyrocket a budget – and that is making customizations after you’ve started the build. But, if you start with good plans and commit yourself to them, it is very feesable to stick to your original budget.

Sending the above spreadsheet to both designers and builders, and asking if they were realistic figures, they all came back stating that we’ve covered all aspects and should be able to complete the project within the budget we have listed. And that, is music to our ears!!

Since this is a very long video because we have tried to keep it as detailed as possible, here is an outline of subjects covered if you’d like to bounce through to the areas that interest you:

Hey again M&J

Just watched you cost vid, pretty much covered it all. Awesome. I had another thought for you on the kit, ask Bob (Oram) or Jeff (Schionning) if shipping is mandatory with their kits. What I mean is, both use west system epoxy mostly although our kit also included atl kinetics resin for under waterline wetout, nevertheless you may be able to source that (and the various powder additives) locally rather than pay international shipping on it, same goes with double bias and uni glass, which leaves the composite panels. I have heard that designers may sell you the rights (single use) to the CNC files but it very much depends on if they know and trust the composite panel makers. If they do there may be a company similar to ATL in the US to make you the panels. Just a thought based solely on the absurdity of West being made in the US, shipped to Australia only to be shipped back.

Great to hear from you! *anyone reading this- Paul built a beautiful Schionning cat and did the best documentation I’ve seen of the process at Yikes.com.au

Funny, the first suggestion I received from Oram was to get my epoxy in the US. Not only is it cheaper, but apparently Epoxy is a hazardous material and just the mess of importing it is best to be avoided. But we’ll probably source the fiberglass straight from ATL. Â In the US it’s more difficult than it should be to get the designer’s suggested cloth weave and weight. Our common weights are just different enough to cause some problems that I don’t want to have to reengineer for.

I did a cursory budget for building the panels myself, but unless my supplier’s bulk pricing was way too high, the ATL price vs infusing my own panels were surprisingly close – and it was even closer getting them from Schionning’s South African manufacturer. Buying 200 sheets of Divinycell still didn’t get me into the price point to make it worthwhile 🙂 But adding the savings along with not needing shipping and import does get to the point that we’d essentially be paying ourselves a fair wage to infuse them, but I keep thinking that all it takes is one bad hull length infusion and we’d be at a large loss. It would give us continuous panels without need joints, but the South African panels are 40′ long and only need one seam now… so hardly a big benefit there either. That debate still rages on 🙂

Get out there and use that awesome boat! I can’t believe it’s been sitting on the mooring for so long without you guys at least using it as a power boat.

Hey Matt, As I suspected thereâ€™s not much you donâ€™t already know or scoped out. I hear you regarding infusion. I did a bit of research into the kss Kelsall process but in the end decided I perhaps donâ€™t have quite enough skill or attention to detail to be confident in my ability to infuse a 40ft panel, the last thing you want is delamination. But the â€œout of a moldâ€ with paint already on sure is attractive, if I was ever to build again, anything that reduces fairing is worth itâ€™s weight in beer in my opinion. And yes, all going well we intend using Yikes later this year, if only around our home port but I have to get the ammenities and comfort up to spec to get Jo on board. Loved the Thai charter adventure vids. Cheers Paul

Great video. Thanks for compiling all this together. It’s compelling enough that I’m seriously considering actually going for it.

Couple of questions: 1. I’m trying to scout the building locations. I live in an apt so no access to a big backyard. I know you mentioned leasing a parking lot potentially .. do you have any pointers. Logistically that seems like a huge problem that I’m struggling to overcome given that leasing an industrial warehouse (if I can find one with the doors large enough) would be at least 20K per yer for the ~2000 sq feet I’d need. 2. Have you considered Spirited Designs (as in Sail Surf Roam). What is it that ultimately made you go the Oram route? Designs seem very similar between Schionning and Oram and even the layout seems similar. 3. Oram build hours estimate and the overall cost seems much lower than Schionning. Did you figure out why that is or am I misreading something.

Thanks in advance! Good luck with your new adventure!

Build location is something we’re still struggling with too. I’ve been limited to online searches and emailing agents (Craigslist is a good source) since we are still in the UK and unable to travel back to the US to personally scout out locations. But since we can build anywhere we want, we can pick the best climate for our build (epoxies have some environmental requirements) Where are you located?

It’s almost impossible to find a warehouse with large enough doors to get a cat out in one piece unless it’s an airplane hanger. The typical way most ‘home” builders do it is to remove the wall of the warehouse to pull the boat out… it’s not that hard or expensive to do on a steel building. You just have to find a landlord that is okay with you pulling off the siding/wall and taking a frame or two down for a few days.

The Spirited Designs is a great boat, but for us, it has a few minor traits that we are looking to avoid. Plus, the 38′ is smaller and the 48’ is bigger than we want… no happy medium is offered.

The ‘Cost’ video was just our breakdown for the Oram 45R… like the build video showed the Schionning. We haven’t decided on a design yet- the Oram, Schionning and Grainger are all still 100% in the running.

The Oram is a simpler boat to build. It has a single seam at the sheerline- Schionning is multiple panels that need to be taped and faired- and it doesn’t have the extra seam on deck (another set of panels less on the Oram), and even the cabin top has one less seam (and another panel set less). For better or worse, the stock interior plan is more basic on the Oram too. One simple thing that save a lot of time is the lack of secondary floor (sole) in the hulls. Down below you stand on the hull itself without an additional raised floor like on the other boats.

I haven’t seen Oram list a lower amount of time for the build than Schionning (Grainger does show higher hours). Bob’s site say 5500-7500 hours for the 45R, while Schionning’s site says 5,000 for the Arrow 1360 (design comparison PDF). Schionning shows cost as $260,000 AUD for the 1360 and Bob say’s from $205,500 AUD to $265,500+

And a final FYI- Grainger is doing some redesigns of the Raku- along with new pricing- and will have that information out in the next few days. From talking to Tony, it sounds like they are making a big push this year. Shoot him an email (graingerdesigns.net) and he’ll keep you in the loop with the new detail.

Thanks for that response. I’m down in Miami. I like the year-round warmth for epoxy curing but not sure about the rain/humidity/hurricanes. I’m debating whether I should entrust someone like Ojigawan to build it in VA and just make the trips there as often as possible but that takes the fun/experience of building out of the equation, limits the learning, and last/not least raises the cost 🙂

I did get a quote for the Schionning Arrow 1360 out of Pantawee in Thailand — PM me if you’d like to know what that looks like. In my calculation it comes down to the hourly rate of about $29 which seems very high given that the generous wages in Thailand are about $5 per day.

Good to know about Grainger — will keep my eye out for those new designs.

Did you ask Julian at Current Marine in South Africa for a quote on the Schionning? They maybe a bit more competitive than the Thailand builder since they have so much experience with Schionning (they build the foam kits that Ojigawan uses). I think they also offer pretty good pricing on mast, hardware and all the other needed supplies in SA. Take a look at Current Marine’s CM45 too- it’s an awesome Schionning design.

Good tip. Will reach out to Julian.

By the way — made some progress with locations with some help from my realtor friend. You can find ~ 3k foot parking lots in the Miami area for about 1-1.5k per month. Not cheap but certainly an option. Typically they’re in the industrial areas which have some local laborers that can help with fairing, etc.

Another interesting data point is that some of the builders are estimating about 6500-7000 hours for the arrow 1360 build and trust that 5k hours gets you a very basic/rough boat.

BTW — did you see those new Graingers? pretty sweet! Apparently they have a promotion if you’re willing to purchase plans in the month of June — not sure the details.

The discount is 10% off for the month of June. If you talk to Grainger, tell him we sent you… we get a referral for each customer that acts as a discount for our kit 😉

We’ve found lots for around $500, but those are nowhere near populated areas like Miami. Besides the rain, humidity, heat and cold, one of my big fears with building in a lot is security. We can lock up to tools and supplies in the shipping container, but I’m really looking for a good fenced in area, but this has been a bit harder to find in our price range.

I think 7000 hours is a pretty accurate timeline for a novice builder. I’ve spoken to a guy that built a beautiful Arrow 1280s in 4,000 hours, but that seems to be exceptional and not at all average.

Exploring the Benefits of Small Sailing Catamarans: Speed, Stability, and More

Sailing enthusiasts are constantly seeking thrill and adventure on the open waters. Whether you’re an experienced sailor or a beginner heading out for your first voyage, choosing the right sailing vessel can make all the difference in your experience. While monohulls have been the traditional choice for many sailors, small sailing catamarans have gained immense popularity in recent years. These sleek and nimble vessels offer a host of benefits that make them an attractive option for any sailing enthusiast .

One of the most enticing advantages of small sailing catamarans is their exceptional speed. These multi-hulled vessels are designed to slice through water with minimal drag, allowing them to achieve impressive speeds even in light winds. Unlike their monohull counterparts, which rely heavily on heeling to generate forward momentum, catamarans can reach high velocities while maintaining stability and comfort.

Speaking of stability, this is another significant advantage that sets small sailing catamarans apart from monohulls. With two hulls instead of one, catamarans provide enhanced balance and reduced rolling motions. This means you can enjoy smooth sailing even in choppy conditions or strong winds . The absence of heeling – when a monohull tilts due to wind pressure – not only keeps passengers more comfortable but also eliminates the need for constant readjustment while underway.

Another benefit worth noting is how easy it is to handle a small sailing catamaran. Thanks to their twin hulls and wide beam, these vessels have incredible maneuverability compared to their single-hulled counterparts. They turn sharply and respond quickly to helm adjustments, granting sailors greater control over their course and making navigating tight spaces or crowded marinas a breeze.

Furthermore, small sailing catamarans offer generous space onboard that translates into increased comfort during trips on the water. Their broad decks provide ample room for lounging or socializing with friends and family while enjoying uninterrupted views of your surroundings. Many modern designs feature spacious cabins equipped with modern amenities, allowing for extended cruises without sacrificing comfort.

In addition to these primary advantages, small sailing catamarans also boast excellent fuel efficiency. With their lightweight construction and streamlined designs, they require less power to propel through the water when compared to heavier monohulls. This translates into reduced fuel consumption and lower operating costs, making catamarans an environmentally friendly choice as well.

Moreover, small sailing catamarans are highly versatile vessels that can adapt to various sailing experiences. Whether you’re looking for a thrilling race on the open ocean or a relaxed day trip exploring coastal bays and coves, these boats are up for any challenge. Their shallow draft enables them to access shallow waters or anchor close to shorelines that may be inaccessible to larger vessels. This versatility makes small sailing catamarans not only suitable for seasoned sailors but also an ideal choice for families or those new to sailing.

In conclusion, the benefits of small sailing catamarans are undeniable. From their remarkable speed and stability to their ease of handling and spaciousness onboard, these vessels offer an unmatched sailing experience. So whether you’re chasing adrenaline-fueled adventures or seeking a comfortable escape on the water, consider embracing the wonders that only a small sailing catamaran can provide – setting sail into smooth seas while leaving behind all your worries onshore.

Avoid leaving your sails exposed to prolonged sunlight when not in use and regularly inspect them for any tears or loose stitching that might need immediate repair.

4. Anti-Fouling Protection: Applying an effective anti-fouling barrier on the bottom surface of your catamaran helps prevent marine organisms from attaching themselves to the hulls – saving you valuable time and effort spent on cleaning later on.

5. Battery Care: After a thrilling day out at sea, don’t forget about the batteries powering various systems onboard! Routinely checking battery terminals for corrosion and ensuring they are charged adequately will ensure uninterrupted functionality during future adventures.

6. Adequate Storage Solutions: Organizing storage space efficiently is crucial for maintaining a clutter-free and well-balanced catamaran. Investing in smart storage solutions, such as hooks, nets, or designated compartments for different equipment, can significantly contribute to the longevity of your vessel.

7. Regular Engine Maintenance: Engines are the backbone of any sailing experience, so regular maintenance is essential . Following manufacturer guidelines regarding oil changes, filter replacements, and general inspections will help keep your engines purring smoothly.

8. Safety Equipment Check: Safety should always be a top priority when sailing catamarans. Inspecting life jackets, flares, fire extinguishers, and other safety equipment at regular intervals ensures that they are in optimal working condition – contributing to peace of mind during your voyages.

9. Docking Techniques: Mastering proper docking techniques contributes not only to the smooth maneuverability of your catamaran but also protects it from accidental damage while mooring. Taking the time to practice docking methods can save you from costly repairs caused by mishaps.

10. Weather Monitoring: As with any water-based activity, keeping an eye on weather forecasts is imperative when planning your trips aboard a small sailing catamaran. Being aware of potential storms or unfavorable conditions empowers you with knowledge to make safer decisions while out at sea.

These tips and tricks form a comprehensive guide to prolonging the life and enhancing performance when it comes to maintaining small sailing catamarans. Implementing these suggestions alongside regular servicing and upkeep practices will undoubtedly result in countless unforgettable journeys on the open waters ahead! So hop aboard your small sailing catamaran and embark on new adventures with confidence!

Having a boat custom-built for you

Because of the huge dollars needed to buy a new or even a used catamaran, we would never have gotten a catamaran if we hadn’t built it ourselves.

Let’s start by saying that building any type of larger boat, especially a catamaran, can be one of the most intellectually and physically challenging things you will ever do.

It has been said that building a large boat is the closest a man can come to giving birth to a baby. In other words there is going to some discomfort and pain along the way; you will question yourself on whether this was such a good idea; it’s very difficult to reverse the decision; and though friends will support you, you will be on your own most of the time with your significant other if he/she is game.

Know your boat

You will intimately know every part of your boat. You will know where every wire, hose, bolt, bulkhead, rib, and support is because you installed them!

Pride of ownership

We have often thought what it would be like to just buy a boat from a manufacturer, and know that while owners who have spent a lot of cash (or future life to pay off the lien) their often possessive and competing-with-the Joneses could not begin to compare to our quiet glow of happiness and akinship we feel with Light Wave .

Our boat is like part of the family. So much time was spent on her that we have a major emotional investment. Every time we see our vessel – from a distance at anchor or approaching her in our marina, we say, “What a pretty boat! I can’t believe we built it!” Then that sense of accomplishment settles back in and we feel we have indeed earned the privilege of all of the beautiful experiences we have had sailing, cruising, exploring the beautiful BC Coast and much further a field (or should we say “an ocean”?).

You will be able to pay for the materials as you go and “donate” your time to the cause.

Get a newer design

Many of the production boats that are out there are designs of many years ago because the manufactures have to recoup their capital investment on the mold and production setup. When you build your own you have much newer designs to draw from.

Details on Our Boat Building Adventure

We had sailed our first boat Wave Dancer for five years and had many adventures on the British Columbia coast. In May 1996, I had just returned from a little one-week solo trip in the Gulf Islands of BC when I bought the book, The Cruising Multihull by Chris White (Future link to book review on our web site).

This is the book that got me going (Carllie was not yet convinced). I must have read it a half dozen times over the next 6 months, each time becoming more convinced that this was the way to go for our next boat. It was really still pre-internet web site days so I wrote to all the designers that were listed in the back of the book. Over the next several weeks packages of information started appearing in the mailbox (there is just something about getting packages in the mail – I guess it’s the anticipation). I would pour over these preliminary printed pages with pictures and accommodation layouts. Next, I put a few dollars down to buy the information packages and study plans from the top prospects.

I waited patiently for the study plans. It was like the night before Christmas when I was kid. Oooh the wait! Finally they came, and again I carefully scrutinized the next level of detail. Things were getting a little more serious. The top contenders were:

Richard Woods
Chris White
James Wharram

Click here to read my comments and reviews on their catamaran designs as well as those of Jeff Schionning.

I remember initially drooling over the Atlantic 42 by Chris White, still one of my favorite designs. It seemed to be so seaworthy (by the way if I run into about $800,000 USD any time soon, I am going to buy an Atlantic 55). The most important piece of advice that came out of the material was from Richard Woods:

“Build the smallest boat you‘d be happy with it.”

Axiom #1: The hours to build a catamaran is in almost in direct proportion to its weight.

Which brings us to Axiom #2:

Axiom #2: It takes about 1 hour to create 1 pound of finished boat.

In our case we spent 3,500 hours ( click here for full details on the construction hours ) to build a 4,000 lb. boat (just a little less than 0.9 hours per pound). If a boat’s empty weight is 8,000 lbs., it will probably take about 6,000 hours to build.

When you think about it, you can only mix and handle so much material per hour. More boat weight, more material, more hours. Sure there are some economies of scale on a bigger boat, but usually the systems become more complex and these take longer to install.

This decision process took 8 months and I figured we’d launch in 6 months. It was now January of 1997. Little did we know it would be 26 months and 3,500 hours between the two of us until we launched on June 5, 1999. We ordered the full plans and we were off and running.

We were ready to build, but where would we start the process? First of all, we live in a tiny 480 sq. ft. apartment in Vancouver. Back-yard building wasn’t exactly an option so I found a small garage nearby that we rented for 5 months.

After about 4 months in the garage, I had made all the small parts and it was time to build the hulls. This meant that we had to go larger facilities. We found space at Shelter Island Marina and Boatyard in Richmond. This is the biggest boat yard in the Vancouver area with dozens of commercial and private projects, big and small, under way.

We were out of money by then, so we sold our first boat so we could buy resin and fiberglass. It was a traumatic time as we said goodbye to our beloved Wave Dancer . We were now committed. We than had all the foam for the hull cores, barrels of resin, and huge rolls of matting and roving needed for the fiberglass skins delivered to our “domed stadium”. We kicked ourselves many times that we didn’t take a picture of this raw material stacked in one corner of the empty shed, so we could later show “before” and “after” photos. It was time to build the hulls.

Over the next several months we proceed to join the hulls with the beams I had built in the garage, and then to install the cuddy cabin, cockpit, and decks. By the spring of 1998, it was staring to look like a catamaran. Through the spring and summer of 1998, we continued with the major structural components: mini-keels, hatches, stairs, and interior. Then we went on to the very laborious work of fairing the boat before painting. Don’t under estimate that job!

By October 1998 we were ready to prime the boat and start painting. I really thought this would go quickly. I forgot that I would have to do two more complete sandings to sand off and finish the two layers of primer application. In addition we had to fill countless pinholes – a laborious process somewhat like hiking up a mountain – each time you get to what you think is the top, you see another summit!

The boat seemed to get bigger and bigger. Believe me, there is a lot of surface area on a catamaran. I clearly remember that last sanding: I had reached the end of my physical and mental endurance – I was exhausted. I was ready to move on to the next phase – any phase but more sanding!

We now started spray-painting the hulls bright yellow. It was around this time we decided on our boat name of Light Wave . The painting took over a month: the hulls being the easy part, it was the topsides, the nonskid, and all the masking and prep that seemed to take forever. Happily, the worst of the dust was gone.

By March 1999 we were in the home stretch. The center bridge deck cabin was completed so we took a week off from our paid jobs and lived on the boat in the shed so we could work all day and not waste time commuting. March, April and May were frantic months as we finished all the final touches: engine installation, rudders, windows, deck fittings, electrical, plumbing, mast, and rigging. See our outfitting page (for more details on what we picked and why, and things we would do differently now.

Initially, our electronic systems were relatively basic but included GPS and autopilot see the following link for all our electronic outfitting choices and reasoning for more details.

It was May 22, 1999 and we decided that Saturday, June 5th would be “Launch Day” so we could send invitations to all of our friends. On the Friday night before Launch Day, we still had a number of final things to do, many of them outside. Unfortunately it was pouring rain. We were tired and very wet but the boat had to go into the water next day so we persevered on till everything was ready.

The moment of truth came as Light Wave was lowered into the water. While still in the slings of the Travelift, I jumped aboard to check for leaks. Of course there weren’t any! More food and laughs and tours of the boat for all attending. It was a great day.

Emotionally drained that night, we slept in Light Wave in the water for the first time. It was another week before we actually went out for our first trip as we had to sell the shed, setup sails, and install some final deck hardware.

To sum it up, building a catamaran was a great experience. We learned a lot. Carllie and I grew closer together through it all. We had a great time doing it. We had a beautiful catamaran to show for it. Now it was time for a catamaran adventure !

More than ever before, sailing fans are gaining an interest in catamaran layouts and designs that define performance. Many others are also looking into either buying a cruising catamaran or designing and building one. While building a catamaran is no piece of cake, this article shows you how to create the perfect cruising catamaran layout.

To create the perfect catamaran layout, carefully consider factors like a good hull design, optimal helm station placement, boat stability, and adequate load-carrying capacity. Excellent galley positioning, ease of handling, and spacious living and sleeping quarters are also crucial.

The modern cruising catamaran is a far cry from the simple Polynesian double canoe of old. That’s because structural innovations and new composite materials have resulted in multihulls with impressive cruising abilities. Keep reading to learn more about exceptional catamaran layouts.

The Changing Trends in Catamaran Designs

The early cruising catamaran designs resulted in boats that could sail much faster than traditional sailing boats. In addition, they could glide with ease in shallow waters and required less wind and crew. Unfortunately, these cruising cats were heavy, had small, cramped interiors, and boasted somewhat challenging handling abilities.

Today’s cruising catamarans are different. They boast the utmost comfort, high speeds, and the safety of a well-designed cruising yacht. They are also more exciting, visually appealing, deliver the smoothest of rides, and sport more spacious interiors.

Have a look at the below video showcasing the top ten cruising catamarans:

Features To Look Out for in Catamaran Design Layouts

Cruising catamaran designers understand what most sailors look for in a cruising vessel. They, therefore, design cruising multihulls that address these pertinent issues and more. Some of the features you might want to consider having in your dream boat include the following:

Responsive performance. Outstanding performance allows for pleasurable cruising and ensures your safety since you have more options during difficult weather.
Excellent load-carrying ability . This allows you to have an extended cruising vacation or ocean crossing.
Boat stability . Go for lightweight, robust construction, which results in a lot of buoyancy.
A low center of gravity for smooth rides and enhanced performance. Centering weight around a low center of gravity improves the overall sailing quality, reduces pitching movement and reduces the risk of capsizing .
Adequate bridgedeck clearance to reduce slamming and provide better performance in rough conditions. A high bridgedeck also means less noise and slapping action from the waves hitting the boat bottom, thus ensuring a quieter, smoother ride.
Comfortable sailing. To enjoy a quality life on board, you need comfort while at sea. Thus, elements like gentle movement, no creaks or groans, no bridgedeck slamming, and minimal pitching are essential for quality, peaceful and restful sleep.

Now that you know what a cutting-edge catamaran features, let’s look at how to create the perfect cruising catamaran layout.

Build a Larger-Sized Catamaran

The early catamarans ranged between 36-42 feet (10.9-12.8m). At the time, this appeared to be a good size in terms of safety and ease of handling. However, the boats were heavy, and the additional drag and displacement adversely affected their performance and windward ability.

It’s now possible to make the new generation catamarans lighter, larger, and more spacious with excellent power-to-weight features. The current trend is larger-sized catamarans in the 45-50 feet (13.7- 15.2) range. Composite engineering and technologically advanced equipment such as furling systems, electric winches, and autopilot make it easier for a smaller crew to sail larger boats with confidence. And to do so without compromising safety or stability.

Get the Best Catamaran Hull Design

A cruising catamaran’s performance depends on three main aspects; its length, the sail area, and the boat’s weight. Long boats are generally fast. A light boat with more sail area is also faster than a heavier boat with less sail area. In other words, you can make a multihull faster by making it longer, lighter, or adding more sail.

However, there are exceptions to this rule; a boat with too much sail area is more likely to capsize if there are brisk winds. Also, if the boat’s design makes it too light, it’ll be unable to handle much punishment, while a hull design that’s too slim would make the vessel incapable of carrying any significant loads. But that’s not all; if the boat is too long or too large, it’ll become grossly exorbitant. Narrow hull shape might also mean smaller cabins.

Nonetheless, these three factors alone are not enough to determine a cruising catamaran’s performance. While faster boats boast finer hulls, the wetted surface area tends to increase as fineness increases; thus, fine hulls end up becoming less fast in low wind speeds. Also, very wide hulls mean a reduction in actual performance.

The Prismatic Coefficient (Cp), a measure of how full the ends of the hull get, is the most essential design hull shape factor for any catamaran. A high Cp equals high speeds, although you can still use a lower Cp if you have fine hulls. Nevertheless, the key to a good Catamaran design is a higher Cp for fast sailing.

To achieve a high Cp, there are several things you can do:

Fit bulb bows . Unfortunately, the bulb bows tend to slam in a seaway when you do this.
Have an extensive planning aft section . However, this can increase the wetted surface area, WSA and lead to additional challenges.
Flatten out the hull rocker and add a bustle aft. This helps to add displacement aft.

Build Convertible Main Living Spaces

The open cockpit is now a thing of the past. Instead, pioneering designers for catamaran manufacturers like Nautitech, Gunboat, and Catana now replace traditional-style salons, cockpits, and cabins with spacious indoor and outdoor living spaces. The concept involves merging separate saloon and cockpit areas with duplicate lounge spaces and the use of hard-wearing composite materials.

You can also design the cabin to suit your preferences. You may decide to add a cabin or remove one, add a bathroom, have the forward berth in the hull or on the wing deck.

The design enhancements boost usable space while opening up the living areas.
It reduces time and costs for interior maintenance and cleaning.
Large windows bring in more light, increasing visibility.
Luxurious, spacious, and airy owners’ cabins provide more comfortable living space.

Bulkhead Helm Stations vs. Twin Stern Steering

Many catamaran owners have traditionally preferred bulkhead steering. This helm position remains popular, but twin stern steering positions come with more advantages since they provide greater sails visibility. The twin stern positions are also best suited for racing or day sailing since they often lack adequate protection for extended cruising.

Exposed helms are not ideal for a long ocean passage. Go for a safe, secure, and well-protected helm station that provides good visibility and comfortable space for long watches. Again, it’s best to have all control lines at the helm to establish a static control station. Also, have all push-button-controlled winches, instruments, windlass, and autopilot prominently located inside the cockpit.

Twin stern steering positions give you a better view of the sails
You get a better feel for overall sailing conditions.
Twin stern steering positions lack the necessary protection for extended cruising.

Go for the Flybridge Design

The flybridge design is appealing because it offers excellent visibility, more comfort, and additional entertainment and lounging space for everyone on board. Unfortunately for smaller boats – those below 50 feet (15.24m), there is minimal protection from the elements. As such, you might want to consider adding enclosures to offer protection. The flybridge, thus the helm, remains cut off from the vessel, which makes communicating with the crew a challenge.

It provides great visibility.
It offers comfortable spacing.
It might be unsafe to move from the cockpit to the flybridge in bad weather.
It isn’t easy to communicate with the crew.

Daggerboards vs. Fixed Keels

Average cruising catamarans typically utilize fixed keels while high-performance cats have daggerboards . Fixed keels allow you to beach your catamaran easily, and your hull remains intact if a collision occurs. While you lose some angle when sailing upwind, you gain more interior space in the hulls that you can put to good use.

Daggerboards are essential in a performance cruising catamaran since they guarantee that the boat delivers good upwind sailing, including during difficult situations. During long passages, they allow you to point better upwind though the drawback is that they consume much interior space within the cruising catamaran’s hulls.

Since flying on foils ( hydrofoils ) isn’t that practical on cruising catamarans, designers of larger-sized boats have also come up with modified daggerboards. These daggerboards produce lift and prevent leeway, too, thereby improving performance significantly, as seen with the Catana 59’s curved daggerboards. These foil-like daggerboards lift the boat ever so slightly upon reaching higher speeds, making it feel less heavy and much faster.

At the end of the day, calculating the performance of a boat sailing in a wide range of varying seas and winds might not be easy – despite a daggerboard or fixed keel configuration. This is because upwind speed depends not only on the sails’ quality but also windage and the height of the bridgedeck beyond the water.

The design innovations -curved daggerboards and hydrofoils- improve catamaran performance significantly.
Daggerboards enable you to access otherwise inaccessible anchorages.
Daggerboards take up hull space in the hulls of your vessel.

Galley Up vs. Galley Down

Galley layout are becoming more and more important as more people, including families, start sailing regularly. While at sea, your galley needs to be a safe place, well-ventilated, and functional. Everything should be well-thought-out for the sailor’s comfort, including handholds to make it safer to move around the boat.

While the galley location can either be up the bridgedeck or down in the hull, galley up appears to be the most popular trend. This makes the galley the focal point of both the living space and entertainment areas.

If you have a family, this placement is ideal since you make your meals from the galley and get to spend most of your time here. Many cruising families and couples prefer this arrangement and find separating the galley down the hull unappealing. Besides, carrying hot food up and down the staircase is unsafe.

Still, galley down is ideal for charter boats since it offers a private cooking area and uses up hull space efficiently.

Having the galley on the bridgedeck is ideal for families and cruising couples.
Placing the galley on a similar level with the serving area and cockpit is safer and less tiring.
There’s better ventilation on the bridgedeck, making for comfortable cooking.
There’s less kitchen privacy galley up.
On smaller catamarans, this layout can impact the size of the saloon seating area significantly.

Production Catamaran vs. Custom

The choice of either a production catamaran or a custom design might seem pretty straightforward. Production catamarans from major brands come backed by proven designs, dependable construction, solid warranties, and many years of experience. The catamarans are easy to service, source for parts, and most – particularly the owner’s versions – hold on to their value, making them much easier to resell.

On their part, custom boats are fantastic in that you can tailor them to your exact needs. However, they might be more challenging to maintain or service. That’s because of parts unavailability and lack of construction knowledge.

Choose Quality Construction Materials

The best quality materials to use on your catamaran are both light and robust. While carbon fiber is great, plywood, plywood/epoxy, and strip-cedar are excellent materials too. What’s more, they are also affordable, so you don’t have to get too hung up on cutting-edge building materials. What matters is build quality; thus, a well-built plywood catamaran boat can last as long as a boat made from more high-tech materials.

Combining various materials also helps combat some of the issues that plague plywood boats in terms of resale value. At times, the design tends to make the boats appear pretty dated.

Plywood and strip-cedar materials are affordable and provide excellent build quality.
Plywood boats may have a lower resale value than those built with modern materials.

Consider Ease of Handling

An important factor in handling a cruising catamaran is deck layout. Most cruising catamarans sailed short-handed , so if your boat has one helm, all lines should run back here to allow for a static control station for the entire boat.

The other essential element is visibility from the helm. The 360 degrees of visibility while maneuvering, docking, or underway is crucial to your boat’s safety, as well as life and property. As such, you should be able to view both bows, or at least the pulpits and sterns, while standing at the helm. If not, you may have challenges handling the boat due to blind spots.

Consider the Load Carrying Capacity

A well-designed catamaran is enjoyable to sail in all weather conditions. It’s also much easier to handle than a monohull because of its widely spaced twin engines. But when you immerse extra hull depth, the vessel gets sluggish and moves slower, maneuvering in tight spots or when docking becomes more challenging. Furthermore, the hull submersion reduces bridge deck clearance, leading to hull slamming.

To allow for adequate load carrying capacity, you need a design that provides a generous displacement. This helps to ensure that you maintain reasonable bridge deck clearance even when fully loaded. It also allows you to avoid digging big holes in the water as you drag your transoms.

Displacement refers to the amount of buoyancy designed into the hulls, which essentially means that your boat will cruise better if its weight is less than your designed displacement.

Note that an overloaded catamaran not only loses out on performance but eventually, on safety too. To counter this, choose a lightweight catamaran with hulls bearing cored construction and interiors made of lightweight materials.

Remember, when you go cruising, you will need to carry fuel, extra water, supplies, equipment, and amenities, translating into thousands of extra pounds. Therefore, try and avoid the following design errors to ensure that your catamaran has an adequate load-carrying capacity:

Avoid putting in place too much accommodation space.
Avoid building a heavy boat ‐ use low-tech construction materials.
Avoid installing inboards in a small boat.
Lightly constructed catamarans perform faster and carry more weight.
Cored construction makes for a strong and stiff catamaran, thus enabling good performance.

Final Thoughts

A well-designed cruising catamaran is a joy to behold. Today’s modern technological advancements mean that you can buy or build a light but strong cruising catamaran. And as you can see from this article, there are many excellent cruising catamaran layouts that you can choose from.

However, whichever layout you decide on needs to fit your sailing needs and purposes to ensure you remain comfortable and safe while at sea. Above all, ensure that you go for a vessel that you can handle with ease in all weather conditions.

Table of Contents

Short Answer

Building a catamaran boat requires a lot of patience and skill.

The first step is to choose the right materials for the hull, such as fiberglass, wood or aluminum.

Then, you will need to build the frame of the boat, which includes the crossbeams and the main hull.

After that, you will need to install the decking, the rigging, and other components.

Finally, you will need to paint and varnish the boat, as well as install the outboard motor and other accessories.

Design & Size Considerations

When it comes to building a catamaran boat from scratch, the first step is to determine the design and size of the boat.

This should take into account the intended use of the boat, such as sailing, fishing, or leisurely cruising.

The size of the boat will depend on the number of passengers and the type of activities the boat will be used for.

For instance, a larger boat may be needed if passengers will be standing or participating in watersports.

The design of the boat is also important and should be chosen based on the intended use.

If you are looking to build a sailboat, you will need a design that is optimized for sailing.

On the other hand, if you are looking to build a fishing boat, you will need a design that is optimized for fishing.

There are a wide variety of boat designs available, so it is important to research and choose the one that best suits your needs.

In addition to the design and size, you will also need to consider the materials used for construction.

The most common materials for building a catamaran boat are wood, fiberglass, and epoxy.

Each material has its own advantages and disadvantages, so it is important to research them and determine which one is best for your project.

Finally, you will need to consider the cost of the project.

Building a catamaran boat from scratch can be a costly endeavor, so it is important to have a budget in mind before you begin.

The cost will depend on the type of materials used and the complexity of the design.

It is also important to factor in the cost of any tools that may be needed for the project.

By taking into account the design and size, materials, and cost of the project, you can be sure to build a catamaran boat that meets your needs and budget.

With the right amount of patience and attention to detail, you can build your own catamaran boat in no time.

Gathering Materials

Gathering the materials needed to build a catamaran boat from scratch can be a daunting task, but it is essential for creating a sturdy and safe vessel.

Before starting the building process, it is important to have an accurate and detailed plan for the boats design and size.

Once a plan is in place, it is time to begin sourcing the necessary materials.

The most common materials used to construct a catamaran boat are wood, fiberglass, and epoxy.

When choosing wood, it is best to select a species of timber that is strong and durable, such as mahogany, teak, or cedar.

Additionally, the wood should be clear and free of knots, splits, and other defects.

Fiberglass is a lightweight fabric that is resistant to water and provides additional strength to the boats hull.

Epoxy is a waterproof adhesive that is used to seal the boat and ensure that it is watertight.

It is important to ensure that the materials are of high quality, as this will help to ensure the boats longevity.

Additionally, it is important to purchase the necessary materials in the correct amount and size.

Too little or too much of a material can be a costly and time-consuming mistake.

Finally, it is important to keep any leftover materials for future repairs or modifications.

With the right materials gathered, the next step is to cut the wood and begin the assembly process.

Cutting & Assembly

Cutting and assembly are the most important steps when it comes to building a catamaran boat from scratch.

The first step is to decide the design and size of the boat.

This will determine the type of materials you need to gather and the amount of effort that needs to be put into the project.

After deciding on the design and size, you will need to cut the wood to fit the design.

This includes cutting the wood to the desired size, as well as cutting any additional pieces that may be needed to complete the design.

It is important to ensure that all the pieces fit together correctly and securely, as any mistakes could lead to a weak boat.

Once the wood has been cut, it is time to assemble the pieces together.

This involves attaching the pieces together with glue, screws, and nails, and ensuring that the pieces fit together securely.

It is important to be careful and patient when assembling the pieces, as any mistakes could result in a weak and unstable boat.

Once the frame is ready, it is time to lay the fiberglass, and apply the epoxy to seal the boat.

This is an important step, as it will make sure that the boat is waterproof and durable.

Finally, you can add the finishing touches, such as the hardware, paint, and rigging.

With the right amount of patience and attention to detail, you can have your own custom catamaran boat in no time.

Laying Fiberglass & Applying Epoxy

When laying the fiberglass and applying epoxy, it is important to take your time and be precise.

Fiberglass and epoxy are key components of a catamaran boat, as they provide the strength and waterproofing necessary to keep the boat afloat.

Start by laying the fiberglass over the frame of the boat.

Make sure to cut the fiberglass to size and overlap the edges for a strong seal.

Once the fiberglass is in place, mix the epoxy and begin to apply it.

It is important to apply the epoxy in a thin, even layer to ensure a proper seal.

Make sure to move the epoxy around to get it into all the nooks and crannies of the boat.

Allow the epoxy to cure and then you can begin to add the finishing touches.

Finishing Touches

Once the frame of the catamaran boat is built, it is time to add the finishing touches.

This includes adding the necessary hardware, painting, and rigging the boat.

Hardware: Before adding the hardware, it is important to ensure that the frame is stable and secure.

Add the appropriate hinges, screws, and nails to the frame.

Make sure that the screws and nails are the correct size and do not exceed the recommended load capacity of the frame.

Painting: Once the hardware is added, it is time to paint the boat.

Choose a paint that is suitable for the materials used in the construction.

Make sure that the paint is applied evenly and that the frame is completely dry before applying the next coat.

Rigging: The last step is to rig the boat.

This involves attaching the sails, running rigging, and standing rigging to the masts and booms.

Make sure that the rigging is properly tensioned and secured.

Once all of these steps are complete, your catamaran boat is ready to sail.

Hardware & Paint

The last step in building a catamaran boat is to add the hardware and paint.

This step is often the most rewarding, as it is the finishing touch.

Depending on the design of your boat, there are various types of hardware you may need.

Some of the most common items are cleats, winches, fasteners, and decking.

After selecting the required hardware, you will need to install them on the boat.

It is important to use the correct type of screws and bolts, and to secure them tightly.

Once the hardware is installed, it is time to apply the paint.

The type of paint and color you choose will depend on the design of your boat.

It is important to use a high-quality marine grade paint that is designed to handle the extreme environment of the ocean.

If you are up to the challenge, you can add some custom artwork or detail to your catamaran boat.

Adding the hardware and paint is the final step in building a catamaran boat.

With patience and attention to detail, you can create a beautiful and unique boat that will last for many years.

Be sure to take your time and enjoy the process of constructing your own boat.

Once you have finished the frame, fiberglass, and epoxy of your catamaran boat, you will need to move onto the rigging.

This is a crucial step in the construction process, as it will keep your boat safe and secure on the water.

When rigging a catamaran, there are a few key components that must be taken into account.

First, you will need to determine the type of rigging you will be using.

Typically, catamarans use a combination of standing and running rigging.

Standing rigging consists of cables and lines that stay in a fixed position to provide stability and strength to the boat, while running rigging consists of lines that are used to adjust the sail and mainsheet.

Additionally, you will need to choose the right type of rope and hardware for your rigging setup.

The rope should be strong and durable, and the hardware should be made of stainless steel and be corrosion-resistant.

Once you have chosen the type of rigging and hardware, you can start assembling the rigging lines.

This process involves carefully measuring and cutting the lines to the proper lengths, and then attaching them to the mast and boom.

Depending on the type of rigging setup, you may also need to attach the lines to the hulls and deck.

It is important to inspect the rigging lines and hardware regularly to ensure that everything is secure and in proper working order.

Rigging a catamaran boat can seem like a daunting task, but it is essential for the safety and comfort of your vessel.

With the right tools, materials, and attention to detail, you can successfully and safely rig your catamaran boat.

Final Thoughts

Building a catamaran boat is a rewarding experience that requires patience and attention to detail.

With the right plan, materials, and steps, you can build your own boat in no time.

Now that you know the basics of how to build a catamaran boat, why not grab your tools and get started on your very own project? With the right motivation and dedication, you can make your dream of owning a catamaran boat a reality.

James Frami

At the age of 15, he and four other friends from his neighborhood constructed their first boat. He has been sailing for almost 30 years and has a wealth of knowledge that he wants to share with others.

How much does it cost to build a boat?

A question I often get asked is; what is the cost to build a boat like Tokyo Express?

What are the costs to build a boat of this size? It’s a good question and a topic I spent a lot of time trying to work out myself before I began.

Second-hand boats are cheap these days, although cats still hold their price better than keel yachts. With the interior fit-out work included, I put in close to 8,000 hours of work, creating my boat. But that also included building a shed, designing a lot of my own things – everything.

It can be done quicker than I did, but there is still a lot of work involved. Putting an hourly rate on your time spent building a boat, and adding that to the cost of materials, may make it appear an expensive exercise.

Some people suggested I was wasting my time putting in so many hours when 2nd hand boats are cheap. Just go out and buy one! If you are well paid, and the only reason for making a boat is saving money, then maybe it is better working longer in your day job and buying a boat.

Comparing apples to oranges

But my reasons to build were not just about saving money .

Building my boat was one of the most rewarding things I’ve ever done, it falls more into the category of a hobby. I lose track of time whenever I’m in my shed creating, even on small projects.

Making a craft you can live on, and sail across an ocean with, takes it to another level. The joy and satisfaction I felt, launching a boat I’d spent the last three years building, are not something money can buy.

You will never feel the same about a boat you buy as the one you have built. Creating your own craft also gives you the chance to make it how you want, and build it to meet your standards. Even if you are building from plans, you can still make plenty of changes and tailor the boat to fit you.

So calculating the cost of the hours I worked and adding that to the material costs, and comparing that to buying a boat, for me, doesn’t tell the whole story. It is like counting the hours you spend playing tennis, or whatever your hobby or sport is, then working out how much money it costs you in lost work hours. Maybe it’s not quite the same, perhaps it’s somewhere in between.

I built because I loved doing it, and saving money was a nice side effect of doing the job myself. When I added up the material costs without counting hours, it was a lot cheaper than buying a boat. Also, it was built to my standards and the way I wanted it. And it was a new boat. You might find a second-hand boat cheaper, but it is just that, second-hand. That’s comparing apples to oranges, it’s not the same thing.

Now, to answer the question.

The cost of raw materials and equipment to build TE, added up to around $75,000 (AUD), in 1995. Things have gone up since, but something’s not so much. In fact, some items are cheaper these days. To put things more into perspective.

Epoxy cost me $13/litre back then – buying 200 litres bulk at a time. (The price in Oz for buying 20 litres in 2016 was $24/litre).
Paint I think, is cheaper these days.
Wood hasn’t increased too much.
Electronics are less expensive (and better).
Solar panels now cost less than 1/10th of what I paid.
Tools are considerably cheaper today.

I sold the boat for about 3 times more than the material costs, after living 5 years on board, which is in line with the rule of thumb I’d heard many times, that the material costs are half to one-third the value of a boat.

I think it’s rare to get the same sense of satisfaction working in a job for someone else, compared to being your own boss, managing your own project. So while my “hourly rate” was not that high, if you want to look at it that way, I did earn money when I finally sold the boat, and they were the most enjoyable 3 years work I’ve ever done.

In my book “ Building Tokyo Express “, I talk more about the cost of building and describe how I built my boat. I had more time than money and made a lot of the systems and major components, that you would usually buy or have made, myself. It saved me a considerable amount of money. You can weigh up for yourself if it is worth it or not.

If you have more money than time, you can get some or all of that work done for you and finish the boat quicker. The timeline in the back of the book, details how long it took me to complete each part of the boat along with many ideas and things I learned during this time. It can be done a lot more economically than you may first think.

I hope this gives you a little more insight into the costs of building your own boat.

Boat building with a CNC router

June 30, 2017

thanks ,,, great information and great professional designs . I know ,because I was born in Alameda california

Tim, I’m reading your book and checking out your website. I have built a nine meter Jarcat in my backyard in Adelaide and launched her in 2002 after five years of building. I have modified the plans with the designers consent (twice) and I now live on Lake Macquarie with ‘Cobwebs a drive to the ramp, put the dinghy in the water and get onboard all within ten minutes. ‘Cobs isn’t an ocean crosser but she is a very nice coastal cruiser. She cost me around $70k but I made a few expensive mistakes, like buying and fitting a diesel motor only to change it over for an 18hp four stroke outboard. I also had a stainless canopy, liferails, pushpit and pullpit made which was about 10 percent of the total costing. Like you I’m a fitter and turner l and have designed and built a number of fittings in stainless and aluminium. I built the steering wheel for less than $30, the new ones being over $400 at the time. I am enjoying your body of work and can relate to a great deal of it, I find we have the same philosophy towards things boatie, best regards Ross C.

Hello, Ross. Thanks for your comment. Yes, we have similar philosophies and fitter backgrounds. A good trade to come from;) It’s a good feeling to be able to make things, that are just as good or better than something they try and sell us at 10x the price. Your boat sounds great, and you are still enjoying her. I need to get back on the water too. Take care. Tim

Hi Tim, I watched all your videos and left a comment, to which you kindly responded. I am really thinking seriously about this now and although I have no way of building it myself because I am fully engaged in my business, it happens that my business is a factory and I have workers or can hire a few more to help me with this. I was just looking at the Arrow 1500 and I think I can build that much cheaper than they suggest, which is A$290-350k for materials, assuming you buy their kit I presume. I won’t be buying that. Their full plans, manual and support cost A$19,500 which, for a professional design with support, is probably reasonable I think. I do not want their onboard motors or big fuel tanks. Your idea for the Tokyo Express was brilliant I think. I would look at building a compartment to take a couple of outboards and put them on vertical slide rails with an electric actuator to drop them down vertically into the water through a sliding trapdoor. I think this would save a heap of space, be far cheaper than diesels and be a lot easier to maintain.

They estimate that this would take 7000 hours to build. http://www.schionningdesigns.com.au/arrow-1500 For me the cost of 7000 hours is less than US$30k, not counting any time from me. I will source most of the materials locally and use our own wood for the hull and fitout. I don’t want to use their sandwich panels, I will do it the way that you did back in 1995.

If I can afford to do this, the plan would be to sail down the Yangtze and head over to Japan. After a few short runs based out of Mizushima, I will sail back to Perth to retire on the coast. Ideally a place with a berth for the boat. This one looks good! https://www.domain.com.au/33-2-the-palladio-mandurah-wa-6210-2016381113 The flat is a bit small, but the boat would be great guest accommodation. Maybe with A/C plugged into the mains!

I will download your manual and get your book sent to me. I can’t buy it online from here. I will let you know how I go. Send me an email and I will keep in touch. If you get to Perth in about 4 or 5 years time (after I retire) you will have a place to stay. Regards Terry

Hi, Terry. That sounds like a great plan you have. You have the most important thing already, a place to build. I wouldn’t build from a kit either, that is why they costs you quote are so high. Strip plank is a great way to go. All the with your planning, Terry. My email is [email protected] . 👍

Hi Tim, really like your videos and webpage, I’m going to buy your book, I was thinking to build a catamaran, but I question myself if it is not better to build a bigger trimaran, assuming that is much less material comparing the same lenght. So instead a 40 foot cat I could build an 60 foot tri, what do you think? have you thought to build a tri?

BUILDING RAKU FROM A KIT
Duflex Kit Construction in 9 Steps

BUILD YOUR RAKU CAT WITH A DuFLEX KIT BY FOLLOWING THESE NINE BASIC STEPS

Step 1. Kit Design

Work with us to finalise the details of the design you have chosen including any design options or additional modules to be included in the kit.

We will determine the laminates, the number of panels required for each laminate, create the cutting files and prepare a quote for the kit if it is not already priced.

Once the design details and pricing are confirmed you are ready to place your order.

Step 2. Unpacking

2. The kit arrives at your workshop door, usually by container, as a stack of 1.2m x 2.4m routed composite panels ready to be joined. The shipment will normally include additional reinforcements, resins, and ancilary products as specified.

Unpack the shipment and stack the panels out of the way of the space where the panels will be joined.

If you have purchased a joined kit many of the panels will already be joined up to the length that can be shipped in a container (12m).

Step 3 Joining the Panels

Set up the work space where the panels are to be joined.

The panels have a scarf join called a Z join that facilitate the join without needing tapes.

The joining can be done with a heated Z press that cures the epoxy join quickly. Alternatively they can be joined with clamping pressure.

If the panel are are being joined with the Z press you will need an elevated work bench the full length of the longest panels you are using. (image below).

If you are joining them with a clamping technique the space can be on the factory floor.

A nesting booklet is provided with the kit to show how the panels are joined (right)

Joining the panels with clamping pressure

Panels are being joined into a single long panel by painting the surfaces of the scarf join with epoxy screwing through plywood battens that have a release film applied to one side.

Joining the panels with the Z Press

Step 4 Stacking Joined Panels

Once the joins are cured the panels are stacked to one side until they are needed for the job. The inividual parts should not be cut free of the panels until they are required.

Bulkhead and floor panels will be needed before the hull sides and cabin top so they should be left to the front of the stack wherever possible.

Diuflex Kit Construction Header image step 5.

Step 5. Separating the Parts

When assembly is ready to begin the individual parts are separated from the panels by cutting the joining tabs. It is likely you will be building onto moulded hull bottoms that have been built from strip planking or another method of building moulded components. The process for building moulded components is described in another article.

Step 6. ASSEMBLY

As the joined panels are assembled onto the job you will need to apply glass tapes to the joins as specified in your plans.

Panels can be surfaced and coated inside and out with high build while they are on the workshop floor to minimise fairing time once they are assembled to the boat. The paint on the panels shown here has been kept back from the edges to provide a good bond for the tapes.

Duflex Kit Construction Assembly image-01

Smaller items such as steps, seats and dagger cases are nested into the kit and for the more complex parts diagrams are provided to assist with the assembly process.

Duflex Kit Construction Header Image Step 7

Step 7. Interior

Interior kits can be ordered with the primary kit, or they can be ordered later when final decisions have been made about the interior arrangement.

A compromise solution is to order the interior as a set of plain planels that can be cut to shape on site after finalising the layout.

Step 8 Fairing, Painting, Hardware Installation

8. The DuFLEX construction process goes a long way to minising the amount of fairing that has to be done, but inevitably any boat that has not come out of a female mould will require some level of fairing and surface preparation prior to painting.

The fillers and resin systems required for the fairing work are normally supplied as part of the kit.

Hardware installation is the same as for any other form of construction using high density core inserts or consolidated laminate in way of fittings.

Step 9. Sailing

Go Sailing. This Barefoot 40 Catamaran was built entirely with a Duflex kit in Foam/Glass and Epoxy resin systems from ATL Composites

Catamaran Construction – Hulls, Laminates, and Composites

Post author By BJ Porter
Post date October 15, 2020
3 Comments on Catamaran Construction – Hulls, Laminates, and Composites

It’s a given that catamarans are more sensitive to weight and loading than monohulls. Catamaran builders strive to build the lightest boats they can without sacrificing strength and stiffness, and have adapted new building techniques and materials to meet this target. Cutting weight allows more passengers and gear without sacrificing performance.

And the marketing materials reflect it–they load every review and website with polysyllabic technical jargon describing the design and production choices each builder made to deliver the best boat they can.

But when you’re reading a brochure and you come across phrases like “ hand laid bidirectional GRP ” or “ vacuumed bagged e-glass with vinylester resin over a Divinycell core ” do you know what that really means?

All modern production catamarans are made with “FRP” construction (for Fiber Reinforced Polymer). Composites aren’t new–it’s just using materials together to strengthen the whole assembly. Straw was added to bricks centuries ago, and steel reinforced concrete is a staple of construction over the last century. For boats, it’s the use of stranded fibers and cured resins which make FRP different.

The term “FRP” doesn’t get into the technical detail of which fibers and which plastics, and how they’re put together to build your hull. There’s a wide variety of fiber types which can be stranded, woven, chopped or sprayed in a varied of patterns then combined with several types of resins to make hulls with different characteristics.

Some FRP techniques produce lighter, stronger shapes, while others are quicker to build and less expensive to produce. The choice of technique is a function of many factors, from the number of hulls and parts to be built, the type of parts, the budget for the project, and many design specific requirements for weight and strength.

1. FRP Basics

The principle behind all FRP construction is the same – you lay our fibers in the shape you need, then saturate them with resin, removing all the air and voids you can. Resin is left to cure, then the piece is ready to finish and use.

The reality is more complex, since building a boat isn’t like making a flat board or a simple door. You’ve got a complex shape with a designed set of curves to build. “Tooling” is the set of shapes to make the boat parts; molds to cover with fiberglass to get the right shapes.

That’s what makes FRP so effective – you can make almost anything out of it. But to do so requires a lot of choices about what you need for the project at hand.

There isn’t a “best” all around material or technique choice for all jobs, and sometimes a lower cost technique or easier to work with material may be the better solution to the problem.

A. Fiber types

Fiber choices in the last few decades have expanded past the glass fibers used in the first mass produced boats in the 1960s. FRP construction wasn’t new even then, they built the first composite boats using modern fiberglass in the 1940s.

The major fibers used in marine construction fall into three categories – glass, aramids, and carbon. The primary differences are in the strength to weight ratios of the fibers, durability, elasticity, and cost. Some construction may use blends of fiber types to combine performance characteristics.

Glass – the most common material still, because of its low cost and versatility. The most common variety used in GRP (Glass Reinforced Polymer) is “E-glass” which refers to its strand size and mineral content. Other grades have different and sometimes better mechanical properties, but may be more expensive and less appropriate for boat building use. Fiber sizes run 10 to 25 microns for E-glass, though other grades may be smaller.

Brands like Leopard, Lagoon, and most higher production volume builders use E-glass.

Aramids – this includes brand names like Kevlar, Technora and Twaron. They have higher tensile strength than E-glass, and resistant abrasion and punctures. Kevlar is a common choice for bullet proof body armor, and can built a tough, lightweight hull. The materials can be difficult to work with, as it is very tough to cut the cloth. It is often blended with carbon fiber or other materials – Catana is known for using Twaron blends in hull construction.

Carbon – the ultimate in lightweight, strong construction material. Carbon fiber is the most expensive fiber, and is available in a variety of weights, grades and strengths. Fibers are smaller than glass – down to 5 Micron.

The lightest, most expensive hulls are made from carbon, but a catamaran builder may use carbon in places other than the hull to add strength and stiffness. Carbon boards, rudders, and reinforcing structures can enhance performance without driving the price of the boat beyond reach. Carbon is the fiber of choice for many custom builds, racing cats, and Gunboat.

B. Mats, Strands, Roving, Direction, and Weights

Fibers are woven into matting and cloth for construction. Depending on the application, different weights of cloth and cloth patterns and weaves may be more appropriate for the job.

Cloth weight refers to the weight per square yard (or meter) of the cloth. A square yard of nine ounce cloth weighs nine ounces. The heavier the cloth, the stronger it is in a laminate.

Fibers carry loads along their length, so cloth weaves have directionality to their strength. Most builders use several layers of cloth with different orientations to give good universal strength to hulls. Specific FRP applications with strict load-path requirements may have more unidirectional fiber layering – for example, a chainplate manufactured from carbon fiber may use unidirectional fiber.

Cloth – fiberglass cloth is commonly used on outer layers of composites. Cloth may have unidirectional or bidirectional strength. Bidirectional cloths have maximum load strengths in two perpendicular directions. Variations on weaves like a modified twill allow a more flexible cloth for better shaping around complex molds.

Mat – is omnidirectional strands of fiber compressed into a cloth. This is often held together with a resin soluble glue, which makes mat great at conforming to mold shapes without folding and bunching as it collapses when wetted. Because the strands do not align, fiber strength is the same in all directions.

Woven Roving – a heavier cloth made from larger bundles of strands. Woven roving allows for quicker buildup of material and strand weight.

Most FRP layups include multiple layers of different cloth and mat. Finished layers may be finer cloth over courser cloth, over woven roving and mat.

Three primary resins are in common use in marine construction – polyester , vinylester , and epoxy . All resins have materials safety concerns and require care in their use and handling.

Polyester is the least expensive and requires breathing protection because of the VOC emission (Volatile Organic Compounds…nasty, smelly fumes). It doesn’t have good bonding/gluing capability, and should only be used with glass fibers for structural building. Some polyester resins are referred to as “isophthalic” resins.

Vinylester is chemically similar to a hybrid of polyester and epoxy, and performs best with fiberglass. It shouldn’t be used in high strength applications with carbon or aramid fibers. It has some adhesive qualities which polyester lacks, it shrinks less during curing, and has better impact resistance.

The added strength of vinylester coupled with increased water resistance makes it an attractive option for many catamaran builders. It costs less than epoxy, but still has better performance than polyester.

Epoxy is the most expensive, but is three times the strength of the others. It offers the best adhesion and the only resin for building structural elements with carbon and aramid. It resists water intrusion better than the other resins, resists blisters, emits no VOCs, and shrinks less. The major drawback is it is more brittle if it takes an impact.

While epoxy is “the best” in terms of strength and ease of building, there are many applications where other resins are appropriate. Budget is a big driver – a boat made from E-Glass doesn’t need epoxy resin, and considerable cost savings to meet a construction price target may drive the choice.

They can build quality boats from all material combinations, but price and performance will drive materials choices to keep some boats more affordable.

2. Cored Construction

What’s the best way to make fiberglass strong? To a point, you can make it thicker. As it gets thicker, it gets heavier. A hollow shape can take more compressive load than a solid one of the same weight, and the same principle applies to fiberglass construction.

Consider an I-Beam used in building construction. It has the same strength (or more) as a solid rectangular beam of similar mass. The compressive load on the beam is supported by the outside edges of the material, the metal in the middle doesn’t contribute much to the strength. So we can remove metal to get the “I” shape while still keeping those sides rigid, making a lighter girder with less material.

The same principle applies to cored construction with fiberglass. Making a sandwich of two layers of fiberglass with a light core between them allows for the greater strength with weight savings.

There are drawbacks – the biggest risk is damage which breaks the skin, which can let water into the core. Earlier cored construction used materials prone to saturation and rot if they got wet. Some builders opt to do cored construction above the waterline and solid below to minimize some of these risks.

But the advantages in weight savings and increased stiffness offset the drawbacks, and there may be a few other side effects like sound and temperature insulation. Like resins and fibers, core materials offer distinct advantages, disadvantages and price points.

Most builders have adopted a hybrid approach, building solid hulls below the waterline, and cored hulls and decks above. This gives a balance of weight and safety.

A. Balsa Core

Balsa is light and inexpensive. The first cored construction used balsa, but it has the disadvantage of being wood. As a natural material, if it gets wet it can rot and break down. Builders use “end grain” balsa – shorter cross cut sections – to prevent wicking of water if there is an intrusion.

B. Foam Core

Closed cell foam cores give good strength to weight savings while minimizing water intrusion. If you get water in the core, it won’t spread very far. Divinycell is a popular PVC foam core, though there are several choices with different densities and compressive strengths.

Some foam cores are not suitable for heat treatment, but infused or vacuum bagged boats like the Outremer and PDQ do well with it.

C. Honeycomb

Honeycomb cores are often the most expensive, but also give some of the best strength to weight ratios. Honeycombed cells made from resin cured aramid papers are some of the best, but also among the most costly. They offer good stiffness, but can be hard to shape. Aluminum and other resin-infused papers are other core materials builders can choose from.

3. Construction and Resin

When building a hull, there are optimal ratios of fiber to resin saturation for target strength and weight. Too little resin and you may not have enough strength (or worse, voids and gaps), and too much, and you’re just adding weight without adding strength. Resins are also a significant material cost in building the boat, so over application not only increases weight but adds cost.

There are many ways to assemble the cores, fibers and resins to build a finished laminate hull – we’re addressing the most common in boat building. Each approach has strengths and limitations, and an impact on the bottom-line cost to build the boat. Any voids or air pockets in the laminate can be disastrous; these techniques have been developed to increase saturation and reduce the risk of voids.

A. Hand Layup / Open Molding

As the name implies, this is the application of resin by hand to cloth as it’s laid into a mold. Wetting is done with a brush, and the laminate is rolled out to remove any air pockets and voids. This is the simplest way to lay up fiberglass, but also the least precise and consistent and will use the most resin.

Skilled craftsmen have built some of the finest vessels in the world this way. Though it’s more popular with monohulls, which are less sensitive to weight, many catamarans built with hand layups on open molds are still out cruising and performing well.

B. Spraying

Using chopped-strand fiber mixed with resin, a “chopper gun” can spray the mixture into a mold to lay down the composite. A consistent thickness can be difficult, but this is a low cost construction technique which makes a very resin-rich laminate. Using sprayed fibers gives lower strength in all directions compared to meticulously laid down mat and bi-directional cloth. But it is a quick technique popular with mass produced, smaller boats.

It is an excellent technique for parts with complex geometry where weight is not an issue, but you will not see it often in catamaran construction. It’s heavy with resin without any resultant increase in strength.

C. Vacuum Bagging (Wet layup)

When an open molded component has been laid up and wetted with resin, vacuum bagging takes the process a step further. After the wetting is complete, air tight plastic bagging is secured around the wetted area, and the air is pumped out of the bag. The vacuum pulls excess resin out and collapses air pockets.

The goal is to get thorough wetting and produce as strong a laminate as possible without excess resin. Knysa and Leopard are two builders that use vacuum bagging on their hulls to reduce weight.

D. Resin Infusion

For resin infusion the cloth, matting and core is laid in place dry, then sealed in an air-tight bag. A vacuum pump attaches to one side of the bag, and on the other a feed for resin. The vacuum sucks the air out of the dry cloth stack, then pulls the resin through the stack, infusing and wetting it.

Resin infusion, when done right, gives the lightest, strongest laminates with no voids and the minimum resin weight for maximum strength. SCRIMP is a variant of the resin infusion process used by some builders, including TPI which build many early Lagoon cats.

E. Pre-preg

Using pre-preg (for “Pre Impregnated”) cloth for your laminating gets rid of the resin bucket. They manufacture cloth with a partially catalyzed resin pressed into it, then it’s chilled or frozen to stop the curing process. There is no need for seperately mixed resins, and there’s no worry your resin might “go off” and harden before you’re done wetting the cloth. Instead, the cloth is assembled, vacuumed, then heated to kick off the curing process.

There are both advantages and disadvantages to using pre-preg for your laminate work. The big disadvantage is the cost; it is most expensive material to use. You also need to chill and store the cloth until you need it, though some can be at room temperature for a couple of weeks without kicking off. And you need an oven which requires some clever tricks if you’re building a forty or fifty foot boat.

But the strength to weight ratio will always be perfect. High tech honeycomb cores are best suited to pre-preg lamination, and without racing against resin cure times, you can ensure perfect cloth placement and precise layout in the build process.

The primary use for pre-preg in boating is high performance race boats. With catamarans, pre-preg may be used high load parts, like Gunboat does for foils and rudders.

4. Industry Examples

Across the catamaran building industry you’ll find almost all the above techniques and materials used, though some are less common. You aren’t likely to find chopped strand sprayed layups in ocean going cats, and hand layups can lead to heavier hulls than weight sensitive catamaran designers prefer. Most manufacturers have moved to vacuum bagging or resin infusion, with a few of the highest end boats using pre-preg for key components.

Built by Robertson & Caine in South Africa, the hull material is vacuum bagged, end-grain balsa-cored E-glass with polyester.

Hand laid, bagged vinylester over an Airex foam core in the hulls.

Earlier Prout catamarans like the Snowgoose 34 featured hand laid solid FRP hulls and decks. Over time they switched to foam or balsa cores for decks and above the waterline.

Older PDQ boats were made from vacuum bagged vinylester – solid below the waterline and cored with CoreCell foam above the waterline and in decks. Newer PDQ models switched to epoxy resin.

All glass is vacuum bagged. Below the waterline is solid E-glass and vinylester. The rest is unidirectional, bidirectional, and triaxial cloths over a Nida-Core polypropylene honeycomb core with isophthalic and vinylester resins.

The Gemini cats are built with a solid hand layup of woven roving and fiberglass mat and polyester resin. Decks are cored with end grain balsa. The Gemini 3200 introduced vinylester resin into the layup to prevent blistering.

Older Lagoons were SCRIMP infused vinylester with and end grain balsa core above the waterline and in the decks.

Newer Lagoon catamarans use polyester and vinylester resins, also infused with balsa cores above the waterline and solid below.

With a carbon fiber inner skin, Catana also uses Twaron aramid fibers in the sandwiched hull over a foam core.

Fontaine Pajot

Primary hull construction is resin-infused vinylester with a balsa cored hull and deck.

Beneath the waterline, Outremer uses a single layer, solid vinylester laminate for safety. The hulls and deck are vinylester with a Divinycell foam core. They stiffen certain components with carbon for rigidity and durability.

Gunboat hulls are epoxy infused carbon fiber with a Nomex honeycomb core. They build dagger boards and other high load components with pre-preg carbon.

Our kits contain all of your basic materials to build your boat to a faired shell stage, ready for painting and fit-out. We have sail-away costing estimates available for all of our standard designs, and this will give you an accurate idea of the overall cost of your project. This costing varies depending on your level of finish, as you can imagine different options vary greatly in price.

Below is a quick glance at what your Schionning Kit will include and what each item is primarily used for, we hope this is helpful and if you should require more detailed information please don’t hesitate to contact our office.

What do I actually receive?

Superlight Balsa - End-Grain Balsa - Foam - Paper Honeycomb - Western Red Cedar - SDI - End-Grain Balsa - 150kg per cubic metre Paper Honeycomb - 50kg per cubic metre Superlight Balsa - 94kg per cubic metre Western Red Cedar - 360-380kg per cubic metre - Foam

DUFLEX PRE-LAMINATED PANELS

DuFlex pre-laminated panels are the main and most important material used in our kits, predominantly in the flat panel designs, however they are used in Strip-planked designs also, though to a lesser extent. These panels are 2400mm x 1200mm and are CNC routed to speed up build time on our Wildernes X Series, as well as some of our power designs. For internal furniture, a paper honeycomb core is used instead of the end-grain balsa wood core that is used for main structural areas. The use of this is purely to save weight in the shell and therefore produce a faster, more responsive catamaran.

The kit process, building your own boat can be a daunting prospect, however to demonstrate each step in the kit assembly process, we've created this guide for you to study. as you can see our kits are the ultimate in building efficiency and have been streamlined over 30+ years to ensure that you're on the water faster and with less effort., how does it all go together.

Schionning Designs Catamaran Kit Build Process - Step 1 The first step to building your dream catamaran begins with a strongback - this is a square frame used to position the temporary frames that will be used to form the hull shape. This frame will be set up and must be square and accurate, a string or laser level can be used to achieve this.

The first step to building your dream catamaran begins with a strongback – this is a square frame used to position the temporary frames that will be used to form the hull shape. This frame will be set up and must be square and accurate, a string or laser level can be used to achieve this.

Step 2 pre-cut frame panels are erected along the strongback in sequence - catamaran building step 2 SDI

The forebeam is now installed along with the striker attachment fitting, as shown above. The bridgedeck is installed shortly after and taped onto the bulkheads with webs installed, this now completes what is a quite stiff and strong platform to work on.

Step 8 catamaran kit building - forward webs and dash will be fitted - SDI

Now that the bridgedeck is in place, the forward webs and dash will be fitted. At this stage, all furniture and internal work begins, with the main panels left off for ease of access when working.

Catamaran Kit Building Processs by Schionning Designs SDI -Step 9 The internal furniture is now installed, if you chose Kit Option 2, this furniture will be pre-cut to your previously decided upon layout. If you chose to receive blank panels, this is the period in which your internal living areas are to be built. This construction uses paper-honeycomb Duflex panels, as these are superior in weight when used non-structurally. Cabin soles, engines and daggerboard cases are also now installed.

Material Choices

Schionning material choices, solutions that work best for catamarans & why, our designs are based on cored composite construction techniques using west system epoxy resin and knitted fabrics. but given the range of today's composite technologies, which solution works best for catamarans and why written by jeff schionning, selecting the correct materials, resin choices.

It also fully protects the boat against water absorption and it can not develop the dreaded Osmosis.

We choose ATL Composite’s resin systems for their superior quality, reliability and value for money.

Having worked closely with the ATL Composites team and their products for many years, we know we can stand by their material solutions, and rely on great service should something unexpected happen.

This may not seem important but when working with a material for an extended period of time, the small things make all the difference.

CORES Which One to Use?

End-Grain Balsa – 150kg per cubic metre
Superlight Balsa – 94kg per cubic metre
Western Red Cedar – 360-380kg per cubic metre
Foam – 80kg per cubic metre

BALSA END GRAIN (150 kg/cubic metre)

Balsa has very good values and we can produce a shell using a very light laminate. It will be very stiff and very resilient to fatigue.

It has exceptional qualities including very high compression strength, extremely good sheer capabilities and fantastic sheer stiffness.

Compressive strength is the resistance to collapsing when pressure is applied perpendicular to the surface as when pushing directly onto the material with the point of your finger. Balsa is far stronger than Foam (80kg/cubic metre) in compression.

Balsa is also very strong in shear. This is when the core sample is held flat between your hands, one hand slid one way and the other slid the opposite way, when the core tears through the middle the core has failed in sheer. The amount of stretch you feel before the core shears is shear stiffness. To compensate for sheer weakness the core is made thicker. So 13mm Balsa may be equal in sheer to 19mm Foam.

(80 to 200 kg/m³)

There are many boats sailing that are built from foam as it’s mechanical properties are good for boat building.

Initially one would expect this cat shell to be lighter as it is ½ the weight of Balsa. We do have to compensate for its weaknesses and will then add to the reinforcement the reinforcement on the outside to spread that compression load over more core and need a triaxial type weave to compensate for the veneer content that runs fore and aft on the Durakore.
Secondly, we need to increase the Core thickness to compensate for the shear value, usually neutralizing the weight advantage.
We only use structural foam core that is closed-cell and cross-linked.

The end result using foam core amounts to a very similar total boat weight. Professional builders can achieve a good result but usually use vacuum bagging and very good molds to achieve this.

Secondary Issues

Balsa can absorb water. It needs extreme neglect to rot (very unusual). Water soaks along the end grain quickly. It travels very slowly across the grain. We use balsa under the waterline especially because of it’s high compression strength for beaching etc. any core type must be sealed. Damage to all cores results in the same sort of repair. Notice a damp spot remaining when drying out to anti-foul… simply grind back the surface glass exposing the core, dry it out and re-glass – it’s that easy.

Timber cores are cheaper than Foam in most cases.

A light, high tech cat returns a far better (often 2 – 3 times) re-sale than lower tech materials. Often saving $10,000 on materials initially, loses $200,000 on re-sale – a serious reality.

Our boats can be built using Balsa, Foam or Western Red Cedar. Combine strength, stiffness, lightness and cost, with ease of use – it just makes good sense!

Average Cost of Buying & Owning a Catamaran (With 4 Examples)

Turns out that owning a catamaran is pretty affordable. Not cheap, but it can absolutely be done on a budget. In this article, I'll show you what to expect.

Sure, there are plenty of unimaginably expensive catamarans available, but a modest, used open catamaran can be as cheap as $6,000 and an additional $1,000 per year.

A new catamaran costs $144,000 on average at 30 foot, while a used one will cost between $29,000-$134,000 on average. New catamarans cost $751,000 at 50 foot, while a used one ranges from $203,000-$690,000. The average annual cost ranges from $2,805-$10,950.

Of course the price of a catamarans depends on many factors, like the size for example, and your choices determine whether owning one is a rich man's game, or actually a very good holiday investment.

It may come as a surprise that you can get a decent 34-foot catamaran for as little as $25,500 on Craigslist.

This will be a long article because there are so any aspects to cover. I'd like to spend some time exploring the costs of actually buying the boat . Then I want to go into recurring costs , like mooring, maintenance, and insurance.

Cost of buying a sailboat

If you're also eager to find out what regular sailboats cost on average, I have published a very similar article on that topic. Sailboats are a lot more affordable than catamarans, so if these numbers startle you, you could check out the cost of regular monohulls .

But first, to get a good sense of the ballpark amounts, I'll give some real-life price examples, like:

what does it cost if you want to keep your cat in good shape and have a good sailing experience? - aka: most people
what does it cost if you ONLY spend the absolute minimum amount to keep her floating?
if I want to sail the world on a budget, what's the absolute minimum?
if sailing is more of a status thing to you, how much money COULD you spend?

But one thing's for sure: there are plenty of boats available, and even if you're on a very tight budget, you could absolutely still make it work. Sailing is in and of itself actually not that expensive: wind is free, water is free, boats can be cheap - if you're willing to look around a bit. It's all the little extras that add up quickly.

Listed below are four boats that make great beginner boats. Since more than 80% of all boats that are bought are second-hand, I'll use the prices of used boats I found on Craigslist and Yachtworld.

If you want to know exactly where the numbers come from, don't worry, I'll explain them after the four examples.

1. Sea Cat 226DC 22' for stressless weekends on the lake

Boat: Sea Cat 226DC 2007 22 foot The one-time costs are $53,615 Your total recurring costs are $9,510 per year, or $793 per month

Let's say you're like me and most other people and just want a nice cat without too much hassle. So you pay people for any important maintenance that's not easy to do yourself. You do the required maintenance and save up for future repairs. You do a little yourself, which saves you a couple of hundred of bucks a year. You also join a (cheap) sailing club to learn how to not trash the boat.You don't want to buy a bad boat, so you pay a fair purchase price.

One-Time Costs

Recurring costs.

2. Extreme Low Budget Kantola Mach II 35'

Boat: Kantola Mach II 1968 35 foot The one-time costs are $26,440 Your total recurring costs are $2,805 per year, or $234 per month

Let's say, for argument's sake, you want to buy the cheapest cat you can, saving as much money as possible on repairs and annual costs. How cheap could you theoretically go without ending up with a trasher?

I think something like this old but sturdy Kantola Mach II will be right for you. It will save you massively on the purchase price. However, beware, you'll have to antifoul the boat next fall, which will cost you (roughly $2,000). It's common with very cheap boats: upcoming maintenance. But if the current owner is fair and discloses it, you may get a good deal.

In this case, you won't join any clubs. You'll simply do the most important maintenance to keep the boat from falling apart, find a nice mooring place in a far-away (cheap) location, and sail along quietly and affordably.

3. Low Budget 35' Cruising Catamaran for traveling the world

Boat: Gemini 105 1996 Cruising Catamaran 35 foot The one-time costs are $85,850 Your total recurring costs are $10,950 per year, or $913 per month

Let's see what it would take to get a good bluewater cat with all the features you'll need to sail across the world on a budget. In this scenario, you buy a fairly priced, not too old cat that is ready to cruise. Something like this Gemini 105 1996 will do.

Not too long, but comfortable enough for extended onboard time, reducing length will greatly reduce cost as well. With boats, you pay per foot, both in maintenance, fuel, and docking costs.

You don't join a sailing club, reserve quite a bit of change for your maintenance fund (since you'll be bluewater sailing), but you don't need to winterize the boat, as you'll simply sail to the Bahamas and stay in the warm waters there. Or at least, that's what I'd do.

Your mooring costs will be somewhat higher, sailing to and from more popular destination, but your overall monthly cost won't exceed your monthly mortgage or rent payments, and you could permanently live onboard without problems.

You'd need an ICC (International Certificate of Competence) to be able to cross all international waters. You can learn how to get your certificate here .

4. Luxury 52' Cruising Catamaran

Boat: Shuttleworth AeroRig 2022 52 foot The one-time costs are $2,326,020 Your total recurring costs are $53,400 per year, or $4,450 per month

So what if you're in it for the fame? Well, don't worry, there are many status symbols to be had and there is plenty of cash to be burned.

In this case, we buy a new cat of 52 foot, which is not overly decadent, but it's a real piece of gear nonetheless. This Shuttleworth AeroRig comes equipped with all the comfort and luxury you'll need for extended cruising in style.

Of course, you'll pay for joining a decent club, since that's where you can show off your rig. We'll also invest something extra into equipment, regardless of the full electronic rig that comes with the boat.

The annual costs will be high due to mooring fees, the club, and pretty hefty winter storage fees that come with a boat this large.

Unlike monohull sailboats, the price difference between new and second-hand catamarans isn't as great. Regular used sailboats go at a 65-75% discount, while the discount for an average used catamaran is just 10% .

The price difference becomes more noticeable the larger you go, with second-hand catamarans of over 75 foot going at a 35% discount , but that's as high as it gets.

Size and condition affect price the most

There are a couple of important factors that determine how much money you end up spending.

Size - length determines mooring costs, insurance, amount of paint on your hull: literally everything gets more expensive with every foot of length
New vs. used - of course, it makes all the difference whether you buy new or used. Typically, the price of a 35-foot used catamaran vs. a comparable new one is 10% lower (ie. $237,714 vs. $261,286).

Price of new catamarans

The price of new catamarans ranges from roughly $1,765 - $54,491 per foot. An average length catamaran costs between $144,000 and $505,000 (30 - 45 foot). Some go for as low as $42,000 to as high as $924,000.

I've looked at the prices of thousands of catamarans (really) on one of the largest yacht marketplaces in the world (- not manually, don't worry: with the help of their search function). This is what I came up with:

Average price new catamaran per foot in USD:

Catamarans get a lot more expensive from 50 foot and up:

under 30 ft: $2,835 per ft
30 - 50 ft: $9,767 per ft
50 - 75 ft: $18,055 per ft
75 - 120 ft: $41,737 per ft

Purchasing price new catamarans

Price jumps at these boat lengths

As we can see from the data above, the average price per foot drastically increases for new boats at the following lengths: 25 foot, 35 foot, 40 foot, 60 foot, 75 foot, and 100 foot . Buy just under these lengths to get the most boat for you buck.

Price of used catamarans

The price of second-hand catamarans ranges from roughly $756 - $39,909 per foot. An average length catamaran costs between $134,000 to $467,000 (30-45 foot) on the second-hand market. Some go for as low as $29,000 to as high as $848,000.

We did the same for used catamarans, comparing thousands of listings. Here are the complete data:

Average price used catamaran per foot in USD:

On average, second-hand catamarans go at 35% less of the cost of a new boat:

under 30 ft: $2,236 per ft
30 - 50 ft: $9,021 per ft
50 - 75 ft: $16,204 per ft
75 - 120 ft: $30,945 per ft

Purchasing price used catamarans

If this is too much for you, you could always rent a boat instead. I recommend chartering. You can get great catamarans at great prices. Check out my charter recommendation here .

As we can see from the data above, the average price per foot drastically increases for second-hand boats at the following lengths: 25 foot, 40 foot, 55 foot, 75 foot, and 100 foot . Buy just under these lengths to get the most boat for you buck.

To get an average of the price of a used sailboat, I went over to Craigslist. I took the first 10 relevant search results for sailboats under, and over 30 feet.

Of course, the averages here are very speculative, as prices vary from day to day. But it gives a broad range of what to expect.

Over 50 feet, listings become meagre. I believe people tend to not place their 80-ft catamaran on Craigslist, but sell it through a broker instead. So I've kept used yachts over 50 feet out of the picture for now.

This is what I found on Craigslist:

Source: Craigslist , Q2 2022

I've calculated the median price, not the average. The median is the price that's most common within the price range. This way the highest and lowest prices don't have as much impact.

The average Craigslist price-per-foot of a used catamaran:

So let's take a quick look at the costs for owning a sailboat.

One-time costs:

Registration : costs of registration differ per state, but usually run anywhere from $3 - $10 per foot.
Taxes : differs per state and country. Most governments want you to pay property tax and sales tax. Sales tax is usually about 5%. Property tax varies and is more complex, so I'll leave that up to you to figure out.
Sailing club initiation fee : $1,500 - $4,000

Recurring costs:

Mooring : $20-30 per foot per year (can be much higher for prime locations)
Insurance : typically 1.5% of the total value of the boat. So a $100,000 30' cruiser will cost $1,500.
Maintenance : a good rule of thumb is 10% of the boat value. Expect to spend anywhere between $1,000 - $5,000 per year for small to mid-sized boats.
Fuel : depends on how much you use the boat and the engine, but on average something between $100 - $150.
International License : if you want to sail on international waters, you have to get your ICC (International Certificate of Competence. Plan on spending anywhere between 400 to 500 dollars.
Safety equipment : plan on spending anywhere between 150 to 600 bucks for lifejackets, first aid kit, and distress signals.
Winterize boat : $4,000
Sailing club: $800 - $1,500

Maintenance cost

Your average maintenance cost will be roughly $144 dollars per month for boats under 30', or just under $2,000 per year.

Maintainance involves a lot of hidden costs We took an in-depth look at everything . The result is a comprehensive article that lays it all out for new boat owners. Read all about maintenance costs

Gas engines run for about 1,500 hours, diesel engines run for 5,000. After that, you'll need to change them out.

A standard 15HP or 20HP outboard gas engine will cost you about $5,000 - $6,000 and needs replacing every 20 years or so. If you do the work yourself, it's more something like $1,000 - $1,500.

A smaller engine uses less fuel, reducing your total cost You can actually use a pretty small engine for most sailboats. To learn how small (and efficient) you can go, I've written a guide on how to calculate it yourself. Read all about outboard engine size

Replacing the sails and rigging

Most people that own a sailboat will have to replace the sails and rigging at least once in their lifetime. Replacing the mast is uncommon, but if you're unlucky and get demasted, it will need to be fixed. So I've added it to the "be aware this might happen" list - but won't add it to the monthly recurring costs.

If you need to replace the mast and boom, prepare to spend anywhere between $15,000 - $25,000.

I won't go into detail, but I have written a detailed article about the exact cost of new sails . It's a really helpful post if you want to know what to expect.

Good quality cruising sails will need to be replaced every 10 years or so.

The cost of new sails is on average:

26' Bermuda Sloop rig will cost you about $1,000 - $2,500.
34' Bermuda Sloop rig will cost you about $3,000 - $5,000.

The cost of the new rigging is on average:

Standing rigging - every 10 years at $4,000
Running rigging - every 5-10 years at $5,000

Bottom Paint

Another important cost will be antifouling, or bottom paint. The cost of antifouling is between $20 and $45 per foot . Since a catamaran has two hulls, it will cost roughly twice as much.

Cost of antifouling a 40-foot yacht is $1,300
Cost of antifouling a 40-foot catamaran is $2,600

Depending on the usage, you may want to antifoul yearly of bi-yearly, making this a pretty substantial expense: $1,300 to $2,600 of additional annual maintenance costs .

Replacing safety equipment

USCG safety regulations require you to replace safety gear regularly.

Lifejackets have to be replaced every 10 years.
Flares have to be replaced every 42 months. You could consider buying a LED electric distress light instead, which will last you a lifetime.
If you carry a life-raft you'll need to replace that every 12 years as well.

Adhering to the minimum safety requirements shouldn't cost you more than $150-$250 every 5 years. However, if you want the good stuff, or need more fire extinguishers, plan on spending more like $600. If you want a life raft, that's another $1,500.

To avoid you have to go cheap on your safety gear, I've put it in the budget for $500.

If you want to know exactly what the USCG safety requirements are, including checklists , definitely check out my article here.

Winterizing your boat

Winterization is an often overlooked cost, but it can be one of the largest expenses each year. If you're like me, and not so lucky to live in Florida, you need to winterize your boat.

Failing to winterize it will increase your maintenance cost over time, as the engine wears out more quickly, and your plumbing and equipment will fall apart. Winter storms and ice can damage the hull and mast as well. It's the best way to protect your boat in wintertime, period.

It consists of two parts:

Winterizing - costs $1,000 to $2,000 - This is the preparation for winter storage. You flush the cooling system with anti-freeze, and the boat gets wrapped in a shrink wrap cover.
Winter storage - costs $100 per ft on average for catamarans (double the regular fee).

Other maintenance costs

Batteries: deep cycle batteries need replacing every 4-6 years at $600
Deck hardware: every 20-30 years (bullseyes, tiller, eye straps) at $3,000

Joining a Sailing Club

If you're new to sailing, you might want to consider joining a sailboat club. This might help you to get tips, make friends, and learn in a safe environment. Most clubs also organize races, which are a great way to quickly improve your sailing skills.

But it comes at a cost. Sailing clubs are very expensive.

Initiation fees range anywhere between $1,000 - $4,000. But that's not all.
Then there's an annual fee of $500 - $1,000 per year. And lot's of additional fees: for dining, lockers, etc.

If you're willing to skip Christmas, go for it.

I've already referred to my guide on the average sailboat cost, which covers the same costs of purchasing and ownership as this article, but for monohulls.

Comparing the two, we can safely conclude that catamarans are way more expensive than monohulls. On every point, you'll pay more per foot for cats, both in the purchase and the upkeep.

On average, catamarans are roughly 60% more expensive than comparable monohulls. But there are exceptions.

To get the exact difference in price between monohulls and catamarans, I've done a in-depth comparison of the data. This gives us a detailed overview of the price difference for different boat lengths, both for new and second-hand boats.

If you want to learn about the price differences, and explore if there's a sweet spot of owning a catamaran for you, I really recommend reading my cost comparison of monohulls vs. catamarans next .

‍ Key Takeaways

There are many sailboats that anyone can build from home depending on tastes
Budget will be the biggest deciding factor on a majority of the process
Consider kits that come with most of what you need or choose ones that are all-inclusive
Design complexities and new materials may make the building time process longer
Plan the best you can ahead of time to save money and your working hours

‍ Buying a sailboat can be expensive, but building your own can save you money. So what are sailboats you can build from home?

Sailboats that you can build from home will likely be a small boat under 20 feet. These could be from many different boat suppliers such as B&B Yachts, Brooks Boat Designs, and Chase Small Craft. Boat plans will vary based on your budget and how much time you have on your hands.

Based on my previous experience, building your own boat will take much longer than if a professional were to do it. You also have to be able to study plans, consider various sailboat designs, and have tons of supplies such as fiberglass tape or fiberglass cloth. On top of that, you will also have to be good with your hands.

‍ Top 10 Affordable Sailboats Anyone Can Build at Home

Building your own pocket cruiser or other styles from boat plans is an impressive feat, as this will need dedicated time and money to assure your boat sails safely. Boat building takes a lot of patience as well, especially since this will not be completed in a fast manner.

How Much Does it Cost to Build a Sailboat at Home?

As you have likely already done so, the math between building your own boat and buying one may be a huge difference. Likewise, you may even enjoy the challenge of taking an older boat that is gutted and restoring with parts from a kit to build one new again.

But how much does it cost exactly to build a boat from the comfort of your own garage or workshop? The prices are going to vary dramatically depending on your situation and material needed to get the job done. In addition, the time that it takes to complete this will also vary.

Sail plans are rather inexpensive if you are aiming to build a small boat. These plans allow you to see the workings of the boat design and what you need to build the boat.

Without these plans, you will not know the exact details of the design and it can cause major issues with the boat’s hull or other areas of the boat. Think of these as the backbone or instructions of the boat’s infancy before being built.

Price Per Square Foot

You should assume to pay anywhere between $300 to $600 per square foot if you are interested in building a boat. Buying a kit outright can be a good way to save time, but oftentimes these do not come with everything you need.

Instead, you should try to source as much of the materials at the best price as possible. Thinking ahead is part of the process and you might be able to score a deal at a lumber yard or hardware store for parts.

Boat Designs Matter

The design of the boat will be much different from one boat to the next, regardless if they are the same size in length. If you are pondering boats that range anywhere between 16 and 20 feet, you should factor in the shape of the hull, any rigging, and various appendages.

Prices tend to increase when there are more complexities within the designs. If you are considering a kit with more details than others, you will also have to pay more for the designs on that as well.

Kits Can Differ

It is important to understand that all kits are not going to be the same. As you gander at sailboat kits online to stitch together, you need to thoroughly look over to see if you have everything you need before buying.

It would also be at your advantage to ask the seller if any additional parts or supplies are needed. This may change your dynamic on the kit buying process and you may pass up one for another if it has everything you need. An all-inclusive kit may cost several hundred, if not thousands, of dollars more to have the convenience of everything in the bundle.

Construction Approaches

Some boat plans may require you to have certain tools to get the job done. This means special saws or planers, which the average person simply does not have.

Purchasing specialty tools might be expensive upfront and hard to find depending on what it is. Your best bet would be to check locally for others trying to sell their tools or consider a boat plan that does not require extensive tools to finish the job.

How Long Does it Take to Build a Sailboat?

An easy to build sailboat could take a while to build from scratch. Many different variances come into play that are difficult to pinpoint for everyone. But how long is that exactly and how will your experience play into this?

A fun project to sail in the wind could take you several months to well over a year depending on the boat plan and how big your boat is going to be. In addition, the materials all need to be accounted for prior to starting in the event a hardware store does not have them in stock.

Time Varies

The time that passes for simple boat designs on small sailing vessels can be done in a few weeks. This is assuming you have everything you need and work non-stop around the clock.

Certain complex situations may make the process long, such as the difficulty of working with some materials. If you are a skilled laborer, it may take you half the time compared to a novice. The amount of time it can take will vary on your availability and skill level.

Planning ahead will undoubtedly offer the most time-saving features. It also helps if you can tackle parts of the project at your own pace.

Complexity of Design

The design of the boat may make the construction process longer. For example, it may take you longer to build a catamaran compared to a similar lengthed monohull.

More complex designs might require more materials, therefore making the process a bit longer to complete. Furthermore, you will also need more experience working with difficult designs and that will affect you more as a newbie.

Be sure to manage your expectations well and do not allow yourself to become too stressed over this fun project. If you can, seek expert boat building advice from a local builder or the company you purchased sail plans through.

Quality Materials

The quality of the materials will matter significantly when building a boat and will greatly affect the time it takes to construct it. Handling fiberglass or carbon fiber might require specialty tools, while wood also demands a certain level of craftsmanship.

If you are not skilled at working with the material at hand, it might affect the quality of the build and you may have to go back to fix mistakes. This will definitely add more time to your project, because mistakes are bound to happen with your first project.

To save time, consider adding the tools and materials throughout the year or as often as your budget allows. You may want to try testing your skills on fiberglass or other materials to get a feel for how to work with it.

I've personally had thousands of questions about sailing and sailboats over the years. As I learn and experience sailing, and the community, I share the answers that work and make sense to me, here on Life of Sailing.

Learn to sail with Nautilus Sailing: A sailing adventure in Croatia

In sailing, there are three rules, we were told somewhat tongue-in-cheek:

Don’t hit stuff.
Keep water out of the boat.
Come back with the same number of people you left with.

I guess we passed our week as students on a Nautilus Sailing learn-to-sail liveaboard course in Croatia since we avoided crashes, came back with the right number of people, and water didn’t get into the boat (except what dripped off our bodies after a swim in crystal clear water).

The liveaboard learn-to-sail week was fun, too. Isn’t that what adventure travel should be? Particularly when it means sailing on a luxury catamaran around the Split Archipelago of Croatian islands – blue skies, translucent waters, fresh seafood, and lunches moored in a private cove with a swim.

“This doesn’t suck!” Nautilus lead instructor and founder Tim Geisler exclaimed several times a day.

Can’t argue with that. And it could be said for every destination where Nautilus takes its liveaboard students — including the Bahamas, Tahiti, and Mallorca. As media, we did less actual studying than our fellow students did on two other Nautilus liveaboard boats also on the Croatia Sailing adventure. We did, however, get a taste of the learning, which started unglamorously enough with a lesson on how to use the toilet, a.k.a. “head” in ship-speak. After that came learning the parts of a boat, how to steer and read all those dials, tying knots (“If you can’t tie a knot, tie a lot,” we were told), anchoring, rescuing somebody overboard (essential stuff, right?), jumping the halyard, raising the mainsail, and the names of the “ropes.” Ooops, sorry, I slipped. Demerits for me. Never call it a rope on a boat; it’s a line, sheet or halyard depending on its function.

No matter how much learning was done – and this is an intense, immersive week — everybody still had fun, from wine-tasting and ice cream sampling, to strolls along the waterfront promenade of Hvar and motor-scootering around the island of Vis. The other “real” students, however, all ended up with a captain’s certification after just a week (and passing some tests), which allows them to charter or buy their own boat. We on the other hand got a great taste of the sailing life that is akin to RVing on the water. Where classroom lessons really don’t suck.

“We want to give students an authentic taste of sailing,” said Geisler. “It’s not just about the white, flappy things. It’s all the things you see and do.”

Meeting fellow students and our luxury ocean ride: Day 1

The week didn’t start with great glamour, however, as an unusual late September storm moved in. We had to don rain jackets and make a dash along the dock to the catamaran to keep from getting soaked and chilled. Then we met our ride for the next week – a Fontaine Pajot Astrea 42 luxury catamaran outfitted with four ensuite cabins in the hulls – two fore and two aft. On Nautilus liveaboard courses, you see, there are never more than four students in any weeklong course. So, you get personal attention and lots of time with the instructor onboard to help ensure you do pass the sailing certification.

Sailing out from Trogir: Day 2

Luckily for our week in Croatia, the clouds started to clear the morning of our departure from Trogir. We motored out of the marina and headed toward the island of Solta – mind you, not the villages on Solta because when you are cruising the waters you can head wherever you want. In our case, the first few hours took us to the Sesula Cove (“Uvala Sesula) on the northwest corner of this small island. But we didn’t just hang out and watch the view. Geisler, our Nautilus instructor for the week, used most every minute during our weeklong liveaboard course, for teaching, albeit perhaps in sometimes subtle ways. On our way to the Solta cove, we each practiced “driving” so we could learn how to maneuver, stop, and turn the boat, all the while talking terminology because sailors really do have their own vocabulary.

Each day started comfortably but not too lazy, and we were usually anchored somewhere by mid-afternoon – either a peaceful cove or an island marina. During lunch or at the day’s evening anchor (or perhaps both!) came the mandatory swim off the back of the boat. Since we sailed with two other boats – a catamaran and a monohull, both with students – we all anchored together each night.

We did get a chance to experience the magic of sailing that first day – unfurling the sails with our own muscle, watch them fill and billow out, and then feel the boat surge forward, powered only by the wind taking us where we wanted to go.

How Much Does It Really Cost to Build a House?

Lee has over two decades of hands-on experience remodeling, fixing, and improving homes, and has been providing home improvement advice for over 13 years.

Cost Variations

Cost per square foot, cost of land, cost per room, cost factors, house building breakdown, average cost by state, how long it takes to build a house.

Building vs. Buying
Ways to Save

Professional vs. DIY Work

New homes are expensive, so it's important to know how much it costs to build a house before you speak to builders.

The national average cost to build a house is about $520,500. The cost of building a house is highly variable, dependent on the cost of land, total square footage, permits, and extra fees.

While it's generally more expensive to build a house than to buy an existing house, building a house offers flexibility, customization, and fewer maintenance duties.

The cost to build a house ranges from $506,860 to $534,300, for an average of $520,500. That's for an average-sized home of 2,560 square feet.

Building costs vary, though, depending on the cost of the land, builder's fees, the size of the house, and the house's design and style.

Some costs are non-negotiable, such as the contractor's mark-up, builder's sales fees, and permits. Other costs are flexible, like the choice of materials and fixtures, size of the house and the lot, and the type of layout.

Cost of Land and Construction

The average cost to construct a house is $392,240—land not included. A 0.4-acre or 17,220-square-foot lot costs $114,620, on average. Combining the cost of the land and the construction brings the total cost to $506,860.

Cost of Builders' Fees

Extra sales costs may come into play when working with some home builders. With these types of purchases, the sales price will be higher due to builder-related costs for overhead, marketing, sales commissions, and profit.

These extras total $137,900, bringing the overall cost of building a house to $644,750.

The average cost to build a house is $203 per square foot.

The cost of constructing a house is $153 per square foot. That's the cost of construction only, not including the cost of the land or builder's fees.

The average cost of land for building a house is $6.70 per square foot. This is the raw cost of the land only—no structures. On average, a 0.4-acre or 17,220-square-foot lot costs $114,620.

Property cost = $6.70 per square foot

The cost of land varies across the U.S. Land in Mississippi, Alabama, and West Virginia costs from $2 to $3 per square foot. Land in Michigan, New Mexico, and Wyoming costs about three times as much.

When determining how much it costs to build a home, it's helpful to break down the total price into per-room costs. That way, it's possible to increase or decrease the size of rooms to move the dial on the house's overall total cost. Or, you can add or remove entire rooms, as needed.

For example, with an average-size bathroom costing over $12,000, it might be worthwhile scaling down its size if you're operating on a reduced budget.

On the other hand, a small- or average-size kitchen costs just over $20,000. If a full-size kitchen with all the amenities is important, it might be worth increasing its size.

A vital point when learning how much it costs to build a house is that some categories cost more or less than others.

For example, interior finishes cost $94,300 and comprise close to 24-percent of the cost of building a house.

Interior finishes cost so much because it is such a broad category including insulation, drywall, trim, doors, painting , lighting, cabinets, countertops, appliances, and flooring.

Framing the house costs $80,280.

After framing, electricians, plumbers, and HVAC crews build out the major systems at a cost of $70,150.

Breaking down the cost of building a house reveals where most of the money is spent: electrical, plumbing, interior finishes, and foundation work.

Electrical work costs about $24,000, or about six-percent of the total building cost. Likewise, plumbing work costs close to $24,000.

Of that costly interior finishes category, cabinets and countertops cost close to $18,000 or about 4.5-percent of the total building cost. Higher-end quartz countertops alone range from $2,120 to $5,960 per installation. To save costs, laminate countertops cost from $14 to $38 per square foot or about $560 to $1,520 per installation.

Foundation work such as grading, excavation, foundation building, concrete pouring, retaining wall building, and backfilling collectively costs close to $40,000 or about 10-percent of the cost of building the house.

The cost to build a house varies state by state and region by region. Availability and cost of building materials, the cost of labor, and climate are a few of the factors that influence the cost of building a house per state.

Generally, it takes around four to six months to build a house.

Some houses take from seven to nine months to complete. A few outlier houses are built in less than three months. Some houses can take a year or more to build.

Cost to Build New House vs Buy a House

From a cost perspective only, it's better to buy an existing house rather than build a new house. An existing home costs $195,530 less than the cost of building a house.

The median price for an existing house is $324,970.

At a full sales price of $644,750 (including the builder's fees), a newly built home costs about twice as much as a new home.

On top of that, buyers of new homes tend to spend nearly twice as much for appliances, furnishings, and property alterations than buyers of existing homes.

How to Save Money Building a House

Given the high cost of building a house, it's worth looking into ways to save on costs. Here are several ways to save money when building a house.

Pare Down Its Size

All other factors equal, the size of the house has a direct bearing on the cost of the house. Reducing the size of the house will lower the cost to build it.

On average, for every 100 square feet you reduce the size of the house, the overall cost decreases by $20,300.

Choose a Simple Layout

Houses with simple floorplans and rooms with conventional elements will help you save money on the cost of building a new house. Features like wet rooms , walk-in showers, dedicated game rooms , or home theaters add to your enjoyment—but add to the cost, as well.

Do Some Work Yourself

Homeowners can save money on the cost of building a house by doing some of the work by themselves. Commonly called sweat equity, homeowner-driven labor can substantially reduce costs by also reducing contractor fees or mark-ups.

Choose Trends Wisely

Not all home-building trends stick. Expensive features like giant kitchen islands, cathedral ceilings, and open floor plans are no longer on the leading edge of home design.

Go with a timeless home design that lasts over the long term rather than elements and styles that quickly age out.

Buy Less Expensive Appliances

Buyers of new homes spend about $4,255 on appliances. But that's just the average. Refrigerators can cost from $3,000 to $4,000 and upwards. High-end dishwashers can cost $2,000 or more.

Investigate appliance reviews for less expensive products that deliver the features you want for less money.

Avoid Changes If Possible

Change orders usually, but not always, drive up the cost of building the home. Change orders are agreements that the builder and homeowner both sign to change the original contract.

Changes might involve more expensive work (such as increasing the size of the kitchen or bathroom). Change orders can address less substantial work, like changing the completion date or indicating that the home buyer will be supplying certain materials (rather than builder-supplied).

Reduce Builder Sales Costs

On average per house, home builders charge $92,720 for sales commissions, marketing, and profit. That's between 14- to 15-percent of the entire cost of building the home.

While these are non-negotiable costs, it's worth shopping around for home builders to find one that charges less for these costs.

Depending on one's inclination and ability, a homeowner can step in during lulls in construction or post-construction and do some of the work. This saves on the cost of contractor-driven work, with its attendant mark-up fees.

Save on the Cost of Interior Finishes

The vast category of interior finishes, about 24-percent or $94,300 of the cost of building a house, lends itself well to DIY work.

A homeowner can install floor coverings like luxury vinyl or laminate or install window treatments. Experienced DIYers can paint the interior or finish the basement .

Potential Savings

Drywall: $13,184
Interior trim: $12,727
Painting: $8,793
Cabinets and counters: $17,775
Flooring: $13,000
Plumbing fixtures: $5,166

Save on the Cost of Final Steps

The cost category of exterior final steps is another area where homeowners can pitch in and do it themselves. Another option is to postpone less-than-critical exterior projects until they're more affordable.

Removing this category from the total house-building cost saves six-percent or $23,650 of the total cost.

Homeowners can take on outdoor work by building patios and walkways or planting trees , shrubs, and grass. More ambitious exterior work includes painting the house exterior .

Landscaping: $9,123
Outdoor structures: $2,178
Driveway: $8,775
Cleaning up: $2,280

It is cheaper to buy a house than to build a house. The median price for an existing house is $324,970. The average cost of building a house is $520,500. That's a difference of $195,530. When a full-service builder is involved, builder's sales fees bring the price to $644,750—around twice the cost of buying a house.
