Monohull or multihull: which is best for blue water?

As former editor of Yachting World, David Glenn has plenty of experience of both monohull and multihull cruising. Here he weighs up the pros and cons

Through the binoculars I could see masts off Basil’s Bar on Mustique. Their lack of movement suggested a fine anchorage, sheltered from the tradewind-driven swell that builds up in the channel between Mustique and Bequia. It soon became apparent that most belonged to cats, immune from the rolling monohulls like ours would endure if we were to stop in this otherwise enticing bay.

More anchorages in a multi

Stability is one of the truly great advantages of a cruising multihull. Not just at sea where the tiresome business of heeling is something that simply doesn’t – or shouldn’t – happen to any great extent, but at anchor too. It dramatically widens one’s choice of anchorages to include those affected by swell – not uncommon in the Caribbean, for instance, where a subtle change in wind direction can make a previously flat calm anchorage unbearable in a monohull. Its comparatively shoal draught widens the choice still further.

I grew up with monohulls, own one, and frankly wouldn’t consider a multihull for the sort of sailing I do. In northern European waters, marina berthing is a regular necessity and completely safe open anchorages are few and far between.

No rolling or heeling, 360° views and one-level living, as here on a Lagoon 52, appeal to many

But if I were to undertake some serious blue water cruising and I wanted family and friends genuinely to enjoy being afloat, particularly those less experienced, a multihull would have to be a consideration. I would have to put aside the question of aesthetics – let’s face it, they’re ugly beasts – and forego that unique and satisfying sensation of a yacht sailing well, because to date I have not experienced it in a cruising multihull. And that’s quite a sacrifice.

More space in a multi

My attitude changed after chartering catamarans in the Caribbean and Mediterranean. The need to accommodate two families comprising largely of teenage children made the choice of a multihull a no-brainer. In a 46-footer we could accommodate a party of 10 in comfort and the paraphernalia demanded by youth, like surfboards, windsurfers, kites and snorkelling kit, without feeling jammed in.

One-level living makes a big difference when sailing as a famly

The cavernous berths in the ends of the hulls, the wide saloon-cum-galley with its panoramic view and the inside/outside lifestyle made possible by the juxtaposition of the big aft deck and the same level saloon, got the entire crew onside instantly.

As an outside living space, with a trampoline at one end and a massive aft deck at the other, there is simply no comparison with a monohull of the same length. So space, linked to stability, makes for an experience that everyone, even the timid and novices, will find hard not to enjoy.

No speed difference

A multihull, like this Moorings 46, has abundant stowage on deck and below, but filling it all will slow her down

Load-carrying ability is a double-edged sword. On the up side there is room for a big crew and its kit, much more fresh water tankage than a monohull, eliminating the need for an expensive, temperamental watermaker, and finding space for a generator should be easy.

On the down side the temptation to overload will probably cancel out any perceived performance advantage. Multihulls can be relatively quick in the right offwind conditions, but if they are heavily laden – as they will be for blue water cruising – there really is no significant speed advantage.

The Gunboat 66 Phaedo 1 piles on the speed, but for blue water cruisers, comfort and stowage is more important than pace

Some new designs such as Gunboat and Outremer have concentrated on performance, but most clients aren’t overly concerned about outright speed and are happy to trade performance for the considerable comfort offered by brands like Lagoon, Broadblue, the Fontaine Pajot stable, Leopard, Catana, Privilege and others.

Mono sails better

Monohulls, like this Amel 55, sail better upwind, and her ballast keel adds displacement, which means comfort when it’s rough. Multihulls can develop an unpleasant motion in a big sea

Upwind, most cruising multihulls won’t point like a monohull with a deeper keel, and when it gets lumpy and fresh, the motion can become distinctly unpleasant. You have to keep a particularly careful eye on sail area too, but more of that in a moment.

In 2011 I was involved in a test of three cruising catamarans and among my fellow judges was multihull design legend Nigel Irens. He pointed out that catamaran buyers have voted for accommodation (which means weight) over performance, so the dilemma of mixing the two has largely disappeared. With it went the spectre of capsize because, relative to their displacement and beam, the modern cruising catamaran is under-canvassed. But that doesn’t mean that sailors can simply set sail and go in any weather.

‘Speed limits’ on a multi

On a multihull, it’s more important to know when to reef. Set speed limits and stick to them

Also on the panel was Brian Thompson, the lone Brit on board the 130ft French trimaran Banque Populaire V that sailed around the world in under 46 days. He told me that the tell-tale signs for knowing when to reef are far more subtle on a multihull. Apart from instinct, Brian suggested monitoring boat speed closely and having a speed limit to trigger reefing. It is easy to overlook a building breeze when bowling along downwind in a multihull, which is going faster and faster. ‘Keep your boat speed within safe limits you should not get into too much trouble,’ he said.

People often ask about anchoring a multihull, which is important as a multihull will spend a lot of time at anchor. Squeezing into a marina can be nigh on impossible, and expensive if you can get in. An essential piece of kit, which should be standard with a new boat, is a bridle that runs from either hull and keeps the anchor cable on the centreline. In many ways this is easier than anchoring a monohull as it prevents the ground tackle from fouling the hulls.

If you do get alongside a marina pontoon you will soon discover another modern cruising multihull issue: excessive freeboard. It’s worth investing in a portable ladder for those marina moments. Of more concern is MOB recovery. There are bathing platforms on both hulls of most new boats, but it’s not the place to be if a yacht is pitching in a heavy sea. So considerable thought needs to be applied to retrieving an MOB if the worst happens.

The recent and dramatic increase in numbers of multihulls going blue water cruising is certainly testament to their appealing ‘lifestyle’ attributes, but one must bear in mind that they are not a fix for all liveaboard cruising challenges. It’s just a different way of doing things. The elements remain the same and can inflict just as much punishment for the unwary on a multihull as they can on a monohull.

Catamaran vs. monohull: Navigating the waters in style and comfort

Catamaran vs. Monohull: Navigating the waters in style and comfort

Embarking on a journey across the open waters has long captured the human spirit of adventure. The realm of sailing offers a plethora of options, each delivering its own unique experience. Among these, catamaran sailing stands out as a modern and luxurious way to navigate the seas. In this article, we delve into the world of catamaran sailboats, compare them to monohull counterparts, and help you discover the ideal choice for your maritime dreams.

Unveiling catamaran sailboats

Catamarans, known for their twin hulls and spacious decks, have redefined the sailing experience. These impressive vessels offer stability, ample space, and a comfortable layout, making them a favorite among sailing enthusiasts. Whether you're a seasoned sailor or a beginner, a catamaran promises a remarkable adventure on the water.

The thrill of sailing a catamaran

Sailing a catamaran brings a new level of excitement. The feeling of gliding through the water with minimal heeling is exhilarating. The wide deck areas provide plenty of space for relaxation, sunbathing, and socializing. Catamarans are also well-equipped with modern amenities, ensuring a comfortable journey.

Monohull sailboats: A classic choice

Monohull sailboats, with their single hull design, embody tradition and elegance. These boats are known for their responsiveness to wind and waves, offering an authentic sailing experience. While they may have less space compared to catamarans, their sleek design and maneuverability make them a beloved choice for purist sailors.

Choosing between catamaran and monohull

Deciding between a catamaran and a monohull often boils down to personal preferences. Catamarans excel in stability and space, making them suitable for larger groups and extended trips. Monohulls, on the other hand, offer a classic sailing feel and perform well in various weather conditions. Consider your priorities and the type of adventure you seek.

Sailing catamaran: A luxurious experience

Catamarans offer more than just a sailing experience; they provide a luxurious way to explore the waters. With spacious cabins, well-appointed kitchens, and modern bathrooms, catamarans feel like floating vacation homes. The comfort and opulence they offer have elevated the world of maritime leisure.

Navigating choppy waters: Monohull vs. catamaran

In rough seas, the design of a catamaran shines through. Its twin hulls provide excellent stability, reducing the rocking motion common on monohulls. If comfort during challenging weather is a priority, catamarans have a clear advantage.

Sailboat catamaran: Best of both worlds

For those who desire a mix of tradition and modernity, sailboat catamarans offer the best of both worlds. These vessels combine the classic aesthetics of monohulls with some of the space advantages of catamarans. Sailboat catamarans cater to sailors who value both performance and comfort.

Setting sail: Monohull yacht adventures

Monohull yachts, especially those designed for racing, offer a thrilling experience on the water. The feeling of harnessing the wind's power to glide through the waves is unparalleled. Monohull yachts are favored by competitive sailors and those who relish the art of traditional sailing.

Exploring the multihull sailboat

Beyond catamarans, the realm of multihull sailboats includes trimarans, which have three hulls. Trimarans offer a unique combination of stability and speed, making them suitable for both leisurely cruises and exhilarating races. They are perfect for those seeking a balance between comfort and performance.

Catamaran sailing yachts: Unmatched elegance

Sailing yachts built on the catamaran platform exude elegance and sophistication. These vessels are designed to provide a lavish experience, with spacious cabins, gourmet kitchens, and lavish lounging areas. Catamaran sailing yachts redefine luxury living on the open sea.

Monohull vs. multihull: Making the right choice

Choosing between a monohull and a multihull depends on your preferences and intended use. Multihulls, including catamarans and trimarans, offer stability and space. Monohulls provide a classic sailing feel and are favored by those who appreciate tradition. Consider your priorities and aspirations to make an informed decision.

Catamaran sailing safety and tips

Safety is paramount when sailing, regardless of the vessel type. Catamarans' stability reduces the risk of capsizing, but it's essential to follow safety guidelines and weather forecasts. Proper training, regular maintenance, and responsible navigation contribute to a safe and enjoyable sailing experience.

Catamaran sailing offers a blend of luxury, comfort, and adventure on the open waters. Monohulls continue to captivate with their classic charm and sailing prowess. Both options cater to different tastes and aspirations, ensuring that the world of sailing remains diverse and inviting.

FAQs about catamaran vs. monohull

Catamaran vs. Monohull: We Changed, Should You?

There are two schools of thought when it comes to monohull versus catamaran. We have done extensive cruising and lived aboard two monohulls and four catamarans over the past 25+ years . We experienced the good and the bad for both single hull and multihulls first hand. Quite honestly, the pluses for catamarans far outweigh the minuses. There are multiple benefits of catamarans. They are faster, more stable and spacious, and have shallower drafts allowing safer anchorage closer to shore. Being on a stable platform with no heeling cuts down on crew fatigue and seasickness leaving the crew more alert and in control of the vessel. Even novice sailors feel more confident on catamarans.

When we built our monohull Royal Salute in the early 90s, catamarans were not established and were looked upon with extreme suspicion by most cruisers, including ourselves. “Safety and the capsize” issue were always the first things to come up against sailing catamarans. It is a fact that monohulls can get rolled in heavy seas but will right themselves because of the heavy lead keel, and while crew and vessel will be battered, the roll is survivable.

However a catamaran once capsized, will remain upside down (jokingly referring to this state of the catamaran as “reaching its most stable position when upside down”). The inability of a catamaran to self-right was and still is a major bone of contention. However, what is not often discussed is that a monohull has about a 5,000 pound keel of lead that is constantly trying to drag the boat to the bottom of the ocean versus a catamaran that has no ballast and is in most cases with modern catamarans, unsinkable.

So the options are to either sail the world on a boat that, if it springs a leak, will sink like a stone or a vessel that cannot self-right in the event of a capsize but will not sink no matter what. So from a practical point of view, here are our observations over the last 25+ years of living aboard, on the advantages and disadvantages of a catamaran.

ADVANTAGES OF A CATAMARAN

1. speed equals safety.

The speed of a catamaran makes it possible to outrun bad weather. While catamarans do not point as high into the wind as a monohull (or if it does, it makes more leeway or slides sideways), it is about 20% faster than a monohull. This means that even if you sail upwind at a slightly wider angle to the wind than a monohull and have to cover more distance, you will still arrive at your destination long before a monohull.

A modern performance catamaran with daggerboards and good quality sails will point as high as a similar sized monohull. It will point the same as a comparable monohull and sail much faster and therefore arrive at an upwind position much sooner than a the monohull. It is important to note that most of the production catamarans on the market are under-powered and are equipped with standard smaller sails. In lighter breezes many of these designs perform poorly unless fitted with bigger headsails, a Code Zero and a square-top mainsail.

While we believe that more comfortable and safer in rough weather , we have to concede that when the weather gets really bad (60 knots of wind or more) we would personally prefer to be on a monohull from the standpoint of surviving. I would say that a monohull is preferable for serious offshore single-handed sailing because you can more easily hove-to in a monohull. We have been in some extreme weather on a number of catamarans and never really felt that we were in danger, although it takes some nifty seamanship.

A monohull could capsize in extreme weather or even roll in a storm, but they generally come back upright. A catamaran on the other hand, will not right itself. But the cat will generally stay afloat, offering a good place to survive while you wait out the storm or until help comes along. Well-designed modern catamarans are very hard to capsize though.

Having said all that, most catamarans can do 200 to 250 miles a day and with modern technology allowing one to pull down weather at will, there is no good reason why you should get caught in extreme weather. A faster boat is a safer boat as it will in many cases be able to outrun bad weather. With good weather routing information a catamaran can avoid most serious weather and, at worst, place itself in the most favorable position to avoid the brunt of a storm.

2. A Catamaran is a Stable, Safe Platform Underway

Catamarans have no ballast in the keels like monohulls do and therefor it relies on beam and buoyancy for stability. Typically cruising catamarans will have a beam to length ratio of roughly 50%, although many designs nowadays exceed the 50% rule of thumb. So, a 45-ft long catamaran will be about 22-ft wide, providing a very stable platform when sailing. Unlike catamarans, monohulls cannot overcome the rolling and pitching with their narrow beam and the lead ballast for stability.

This rolling and pitching makes the deck on a monohull very unsafe whereas on walking around on the deck of a catamaran while underway is far easier since the boat is much more stable, and it doesn’t heel. This makes sail changes and reefing much easier and a lot safer for the crew. Without the rolling and pitching motion, the danger of falling overboard on a catamaran is considerably less than on a monohull.

3. Crew Fatigue Reduces on a Catamaran

Because a catamaran does not heel over like a monohull, it offers far more comfort underway because the motion is mostly fore and aft pitching and very little beam-to-beam rolling. On all points of sail, a catamaran tracks upright and significantly reduces crew fatigue and seasickness. Seasickness is usually caused by things like anxiety, fatigue, hunger and cold, which all add to a sense of disorientation. This leads the crew to making bad decisions and seamanship errors that could be fatal to the crew and vessel. The more stable platform of the catamaran will hugely keep those issues at bay, making the crew more alert and energized.

Every action and chore including cooking is much easier on a catamaran when underway. It is much more pleasant to be on the deck level looking out rather than being stuck “down below.” It is also much nicer to sleep on a boat that doesn’t heel. I remember nights at sea in our monohull when I was rolling around in my bunk unless I was properly wedge in a little corner. That is simply not the case on catamarans.

All these factors ensure that your crew will not expend unnecessary energy to simply try and stay upright, onboard and safe on a long passage. Your crew on a catamaran will be well rested and alert and will be able to function well if a stressful situation arises.

4. Comfort at Anchor

Catamarans provide a wide platform and therefore offer lovely spaces to relax at anchor without the rolling motion that monohulls have a tendency to do in a swell. During our 15 years of cruising on a monohull, we have often had to leave anchorages that we really were not finished exploring because of a rolly, uncomfortable anchorage. Big rollers or swells coming into an anchorage can make conditions in an anchorage very uncomfortable and unsafe.

We were anchored off Funchal on the island of Madeira in our monohull Royal Salute once, when we were forced to leave our anchorage. The rolling became so bad, we were rolling from gunnel to gunnel. The anchorage became untenable to remain anchored, forcing us to go out to sea in foul weather in the middle of the night. This is an extreme case but believe me, we have left many an idyllic anchorage because of a rolling swell into the anchorage. Catamarans, on the other hand, do not roll from like monohulls have a tendency to do and are far more comfortable at anchor.

5. Anchor Bridal Setup

Catamarans are fitted with a bridle, attached to both bows and down to the anchor chain, resulting in a very stable position at anchor. What we found with our monohull was that because the bow acts as a sail (because of the high freeboard), the boat tended to sail at anchor in high winds. It sailed in one direction until the chain snatched and tacked over and sailed in the other direction, feeling like it might dislodge the anchor altogether. The catamaran on the other hand sits at anchor a lot more stable and doesn’t sail around as much.

6. Ease of Boarding on a Catamaran

Thank goodness we were much younger and more agile during our monohull days. Royal Salute and most monohulls of her generation or older, have high free-boards, making it quite a feat to get onto the boat from the dinghy. It was one of the most challenging things to do because unlike the more modern monohulls that have a scoop at the back, we had to climb up on the side of the boat to get on and off. We, of course rigged steps, etc. but it was always a hassle compared to the ease of getting on and off a catamaran from a dingy or from the water.

7. Shallow Draft Equals Better Anchorages

Catamarans have significantly shallower drafts than monohulls, allowing for safer anchorages closer to shore. Most catamarans in the 40-ft to 50-ft range draw between 3-ft to 4.5-ft, so they can anchor in places that a monohulls can not even consider. In the shallow waters of the Bahamas for example, the catamarans have a big advantage. We often anchor our own catamaran just a few feet away from a beach. It definitely allows one to be able to explore areas where the water is shallow without the fear of running aground.

The shallow draft also allows for emergency repairs in shallow water and even doing the bottom job when the tide goes out as we have done in places like Mtwapa Creek in Kenya, East Africa. The catamaran easily rests on her keels on the sand without help making it a breeze to do the “annual haul out” even in remote locations.

8. Dinghy Davits & Dinghy Size

All catamarans have a set of davits that make it very easy to raise and lower the dingy. Our monohull and most cruising monohulls do not have an efficient or easily accessible set of davits. This makes raising and lowering the dingy an elaborate production. Catamarans on the other hand, has davits systems easily accessible and some even have platforms to rest the dinghy on.

The lack of beam and difficulty of lifting the dinghy also limits the size and type of dingy that one can reasonably carry on a monohull. As we all know, the dingy is your transport to and from shore and diving or fishing spots, so the bigger and faster the dingy, the better off you are. A catamaran can carry both a heavier and bigger dinghy which makes the popular center consul dinghy so much more possible.

9. Interior Space and Comfort on a Catamaran

We sailed 32,000 NM on our 45-ft monohull, happy as clams, not realizing that sailing does not have to be done lying on your ear 24/7 while on passage or sitting knee-to-knee in the cockpit at anchor with your two other guests at the dinner table! One can liken sitting in a monohull cockpit to sitting in an empty Jacuzzi, you are always nice and close to the other folks.

Now that we are on our fourth catamaran, there are a few things that have become more evident to us than the incredible space and comfort of a catamaran, not only at anchor but also underway. The cockpit and living space in general are huge compared to a monohull, making for very comfortable and spacious living conditions. It feels more like you are at home, rather than just on a camping trip.

Knowing that one spends at least 90% of one’s cruising life at anchor, it’s important to have good open living space, which most modern cats nowadays offer. A lot of cats have walk around beds, lots of storage, every modern appliance including washer/dryer, etc. However, one has to fight the urge to fill the space if you want to keep the cat light and fast.

Sailing with guests onboard for extended periods of time, in close quarters can become claustrophobic but on a catamaran people are spread out and separated. With guests sleeping in one hull and the owners in another, catamarans offer much more privacy and separation. Some cats even have privacy doors that will close off the entire hull and has a separate entrance onto the deck, which really separates you from the guests completely.

There is very little heeling on a catamaran, so there is no need for hand grips and safety harnesses inside the boat. There is nothing better (and safer) than being able to walk from the cockpit into the living room (saloon) on one level or one step down at most. In a monohull, when heeling at a severe angle, you would have to claw your way from the companionway steps down to the living area, while fighting to stay upright, significantly tapping your energy.

Unless you hit extreme conditions, everything stays put on a catamaran reducing the anxiety before doing passages of having to stow and secure everything. This very issue makes a lot of cruisers reluctant to weigh anchor and explore more often. It is just too much effort to pack away all your stuff once comfortable in an anchorage!

One thing you will notice is that the stove on catamarans are not gimbaled like it is on monohulls and this should tell the story in itself. The stability and comfort on a catamaran is far superior. Cooking is easy and safer. I often open a nice cold beer, put it down to do something and forget about it only to find a warm beer later in the same place I left it. This is not something that happens on a monohull.

10. Redundancy on a Catamaran

Unlike monohulls, catamarans have a lot of critical redundancies. That of course means two hulls to clean and anti-foul, double the engine maintenance, etc. but having two of the critical equipment like engines for instance, outweighs the downside.

With two engines, if one fails you still have adequate propulsion to go anywhere. If by some fluke the second engine also fails, you have a full set of spares to fix at least one of them. Our friends once hit a sleeping whale off Tanzania, and when it dove, it hit the prop, bending it. They limped into the narrow channel on the one engine but at least they could make it to a safe harbor where we surveyed and repaired their damage.

We often only use one engine when motoring while making passage in order to conserve our fuel. The one engine is totally capable of moving the boat along at a good speed unless you are in heavy seas and you may need more power. Other than that we only use two engines to dock or maneuver the boat in close quarters.

Because there are two engines there are also two independent charging systems via the alternator on each engine. If one alternator goes out, there is still another complete charging system. There are two rudders and if one fails or falls off (as has happened to our friends on a monohull off Columbia, where they almost lost their boat) you have a second rudder that is completely capable of steering the boat by itself indefinitely. That holds true for several things on a catamaran!

11. Maneuverability

The engines are spaced far apart on a catamaran and it makes maneuvering much easier and more precise than monohulls, unless the monohull has a bow thruster. We did not have a bow thruster (not many monohulls do) and had to rely on prop-walk and using prop wash on the rudder. A modern catamaran can do a 360 turn on her own axis. A monohull cannot do this and have a bigger turning circle. However, a monohull under sail is much more maneuverable and certainly will tack a lot faster than a catamaran. The ease in maneuverability under engine on a catamaran in close quarters specifically, is vastly superior comparatively.

12. Rigging

Because of the beam on a catamaran the spinnaker pole has become unnecessary equipment. Hallelujah, I say. That pole on our monohull was a pain the behind and I always hated having to use it. On a catamaran, one can fly an asymmetrical cruising chute or spinnaker, using the bows to tack the clew or run a guy through a block so it is very much simplified, easier and safer.We also sail wing-on-wing with twin headsails when we sail downwind. We use our furling jib and furling Code Zero. It is as easy as one, two, three.

DISADVANTAGES OF A CATAMARAN

1. bridgedeck slamming.

One advantage most monohulls do have when underway is that they don’t slam. Catamarans with a low bridgedeck clearance can experience significant slamming in confused seas sailing upwind. This slamming can be quite disconcerting when you first experience it as we did on a Shuttleworth 44 design, our first ever catamaran experience, 20+ years ago. At times, it felt as though the boat was falling apart. Of course the boat was fine but nevertheless, the stress on the crew from the constant noise and discomfort was significant.

Monohulls don’t have a bridgedeck which means no slamming and are therefore a bit more comfortable than l ow bridgedeck catamarans when beating into severe confused conditions or “washing machine” conditions as we call it. Modern catamarans mostly have better bridgedeck clearance and the slamming is significantly less. However, not all cats have a good clear tunnel under the bridgedeck. Some manufacturers build beds into the bridge deck in order to make more space in the chest of the catamaran where the slamming occurs. These protuberances into the bridgedeck tunnel will likely increase slamming. So be mindful of that when selecting a catamaran. We currently own a Bali 5.4 and the bridgedeck clearance on this boat is more than adequate and the tunnel is clear. We therefor experience very little slamming compared to our Prout 45 that we previously owned (picture of sister ship below) with a much lower bridgedeck.

We Explain Bridgedeck Clearance

In the pictures below, the Bali 5.4 has very good clearance from the water to the bridgedeck and has a nice clean tunnel versus the very low bridgedeck of the Sunreef 50.

2. Sailing Downwind

Monohull spreaders are set at 90 degrees to the mast whereas a catamaran has to have backswept spreaders. The reason is that, on a monohull, there is a backstay and using this, plus the intermediates you can get a nice pre-bend in the mast (the pre-bend is to flatten out the main sail and allow for better performance).

On a catamaran with no back stay, you need to use the back swept spreaders and the diamonds to pre-bend the mast. The reason I point this out is because on a catamaran, if you want to broad reach or run, the mainsail cannot be let out all the way because the backswept spreader tips could punch holes in the fabric.

On a monohull, the spreaders are at 90 degrees so you can let the main and the boom out much further which is, of course, much more effective. This is one of the reasons it is better to broad reach and tack downwind on a catamaran.

Whether a monohull or multihull, sailing dead downwind doesn’t usually make great VMG. Therefor a regular cruising cat, much like a monohull, needs a lot of sail area and has to sail deep downwind if it is to achieve a decent speed made good (VMG). This video demonstrates how we achieve this by sailing wing-on-wing downwind.

It is more difficult to find a dock either as a transient or a permanent slip for a catamaran in general because of the wide beam. But this is changing fast and will soon not be too much of an issue. In the USA dockage is charged by the length of the boat in feet, so there is no disadvantage there but, in some places, (the Mediterranean for example), dockage is charged at length times one and a half because of the additional beam.

Since the catamaran is stable at anchor, we mostly anchor out. We have more privacy, a better breeze and usually a stunning view.We have a nice dinghy with a good outboard engine and is big and comfortable enough to get to shore fast and together with the modern conveniences like the generator, watermaker and washer/dryer, docking becomes a non-issue.

It is definitely more difficult to find a travel lift with enough beam for a catamaran for a haulout, while, for a monohull, there are absolutely no problems anywhere. The wide beam of cats also greatly limits the number of shipyards that can haul them out. Most catamarans over 40-ft must be hauled out with a 50-ton travel lift. This not only increases the cost of the haulout, but greatly limits the choice of the shipyards for repairs and maintenance. With limited choice, prices are high for shipyard services.

Catamarans do tend to have a lot more windage than monohulls. This can be an issue especially when maneuvering in close quarters with a strong wind. But I have found that, provided the engines are powerful enough for the size of catamaran, that twin engines negate this problem. Also, many modern large catamarans now have a bow thruster fitted. It is super easy to dock.

The cost of getting into a catamaran is much higher than that of monohulls. That could put a serious dent in your cruising kitty or require you to put your dream on hold a little longer. Pre-owned monohulls on the other hand are very cheap to buy comparatively, because the supply presently far outweighs the demand.

Catamarans are in high demand and they typically hold their value much better and longer and the trend is now heavily in favor of the catamaran market. When prospective buyers contact us for catamarans under $250,000 the choices are very limited and catamarans under $100,000 is near impossible to buy. In this case, your best bet is to go with a monohull unless you go with much older boats like the Prouts or the less expensive Geminis.

Our Own Catamarans & Monohulls

FYI: Royal Salute , a Bruce Roberts 45 monohull, was the first boat we owned and sailed approx. 30,000NM on. Mythral, a Seafarer 30, was our “toy boat” while we were waiting for our catamaran to be built. Even though this classic little monohull sailed around the world, it didn’t have much in modern conveniences like running water. Siyaya was an Island Spirit 40 catamaran that we sailed from Cape Town to Florida on and then taught live-aboard sailing classes for several years. Zuri I was a Prout 45, a beautifully crafted catamaran but by today’s standards is considered old technology. Our Lagoon 450 SporTop ( Zuri II ) is a fantastic live-aboard catamaran. We lived and taught aboard her for three years but sold her last year and we currently own a Bali 5.4 ( Zuri III or Z3 as we call her now). Read about our various boats .

CONCLUSION: CATAMARAN vs MONOHULL

We were dyed in the wool monohull sailors for 15+ years. We loved the pretty lines of monohulls, the sailing ability and what we believed at the time to be much safer vessels. However, now that we have been avid catamaran enthusiasts, we simply can never go back to monohulls. Catamarans have come of age and with modern technology have overcome most objections that sailors of old had against them. They are well designed and built, are safe, and we simply love that they sail fast and upright. There is not a whole lot to dislike about a catamaran when you live aboard. We have weighed all the pros and cons of catamarans and found that the pros far exceed the cons. We made the change to a catamaran and do not regret it one bit!

We hope that this article will clear things up for all the prospective catamaran owners out there.

4 thoughts on “Catamaran vs. Monohull: We Changed, Should You?”

I read that the engineering on the catamarans were improved over the years. Whats the oldest year would you recommend designwise?

Scott, my apologies for the late reply. We’ve been traveling in Africa. Anyway, catamarans have come a long way and improvements in technology is happening at lightning speed. I reckon that even the older model catamarans are good. It depends on what your needs are. If you want something a little better performance wise, I would go for something no older than 15 years.

After buying a catamaran what is the difference in expense of a catamaran vs a monohull. Many articles state that not only the initial cost of a catamaran is more it the operating cost as well.

Hi Todd, it is more expensive. The annual dockage and haul out as well as maintenance will be more expensive. You obviously have two engines to maintain and various other pieces of equipment to service in both hulls. While there is more equipment there is also more redundancy and of course you have the comfort factor. So, depending on your situation, it’s probably worth it.

Catamaran vs. Monohull: Which Is Better?

Table of Contents

It used to be that sailors and powerboaters (blowboaters and stinkpotters, respectively) used to hold the loudest arguments about which was better– sailboats or powerboats. Today, the debate is centered around catamarans and monohulls— how many hulls are best? Is there a best?

Let’s look at what each boat offers— and continue to read for all Pro Boatsetter Tips .

Got a boat? Put it to work

The benefits of catamarans

Spacious for large crews, easier on your body, shallow drafts, safety system in case of emergencies.

Pro Boatsetter Tip: Did you know catamarans have seen a great surge in popularity over the last decade?

If you’ve got a large crew or plan on throwing parties aboard, you’ll probably benefit from the catamaran’s (also known as “cats”) roominess. Cats offer separation on deck with the aft cockpit , forward lounge or trampoline, and maybe even a flybridge .

Inside, cats have cabins and multiple heads for convenience. A cat of a given length (let’s say 40 feet) has 1.25 x the space of the same length monohull. In other words, it feels the same as a 50-foot monohull. It’s also usually laid out in a more user-friendly manner.

Cats have two hulls, making walking easier for kids, older folks, and pets! Because of its steadiness, you and your crew are less likely to be fatigued by the end of your boat trip. Maybe stay out longer to catch more fish.

Best of all, you’re less likely to feel seasickness because they don’t feel “on their ear” even when sailing in high winds and rough conditions. Not to mention, they’re much easier to sleep on.

Most sailing catamarans have a shallow draft perfect for skinny water cruising like the Chesapeake Bay and Florida. They can venture into areas previously off-limits to deep-draft monohull sailboats.

Most cats have double the systems, including bilge pumps, freshwater pumps, showers, heads, engines, etc. This means if one system fails, you’ve got a backup!

Twin screws also offer easier docking and increased maneuverability. It’s much easier to drive a large sailing cat than a single-engine monohull, especially in a cross-breeze and when docking, backing, or maneuvering in tight quarters.

The benefits of monohulls

Performance
Easy cruising
Familiarity
Availability & expense

Pro Boat Type Tip: Operating a monohull can be challenging! If this is your first time sailing on a monohull , make sure to rent with one of our pro captains.

Competitive performer

If you want to win a sailboat race, use a monohull. This boat’s design makes it a favorable contender even when weather conditions are working against you.

Let’s add a caveat here for cruising under power– cats tend to be more fuel efficient because they’re lighter and they’re not dragging a heavy keel through the water.

Easier motion

Monohull sailboats have their own groove. This motion is predictable and distinguishable by pro sailors. Cats, on the other hand, depend on the body of water’s condition state. Also, cats pound when going upwind into big seas if their bridge deck is pummeled by waves, while monohulls tend to slice through the waves.

Familiar handling

Monohulls have been around for centuries, and chances are that you learned to sail or powerboat on one, so their handling is more familiar. A cat’s dimensions may seem intimidating at first, especially if you are short-handed.

Availability & cost

Monohulls are more available, especially for rent. There are simply more of them. They’re also usually less expensive to rent and less expensive to moor in a marina.

The good news about catamarans and monohulls

There’s no right or wrong choice. It all depends on your budget but, above all, your boating lifestyle. So the better question is: what will you use your sailboat to do?

Party at hidden coves with your crew. Take the kids out for a fun sailing excursion. Sunset cruises with your partner. Enter a regatta; win! Rent it out for an extra income.

Fast Bluewater Cruisers: the best new performance bluewater catamarans on the market 2018

Toby Hodges
August 20, 2018

Many monohull sailors who are thinking of converting to mulithulls for distance cruising seek a combination of the speed and feel of performance cruisers together with the space multihulls provide. To offer proper bluewater cruising ability yet not be too sluggish, a fast cruising cat or tri needs to be smartly designed with payload in mind and built relatively light. Here ’ s where the fast distance cruisers like Outremer, Catana, Swisscat, Seawind, Balance, Atlantic, Neel and Ocean Explorer help offer that potential sabbatical or retirement dream.

Just launched: Outremer 51

The original Outremer 51 launched in 2014 and proved popular, selling more than 50 models. It also garnered a number of European and US yacht of the year titles. But things can always improve, so the French catamaran builder has updated the design with the help of feedback from hundreds of owners. The improvements are superficial and substantial: the interior and exterior styling has been changed, but the boat’s performance has also been tweaked. Not only does this make the boat more fun, it is also “an important safety attribute”, says Outremer. With speeds in excess of 20 knots perfectly achievable, you could certainly outrun bad weather and potentially clock up 400 miles over 24 hours. This sleek-looking boat has on-trend reverse bows, curved coachroof and low-profile steering positions. The helms are slightly raised above the cockpit with a clear 360° view out over the coachroof. It may lack the real estate of a flybridge helm station, but it saves weight and allows the boom to be lower on the mast, all of which helps stability and performance. Control lines all lead back across the coachroof to winches within easy reach of the helmsman, except for the mainsheet, which runs along a track on the aft crossbeam behind the cockpit.

The saloon has comfortable seating and a table for six to eight, with a forward-looking navstation that is a good size. Accommodation is three or four cabins, depending on whether you opt for an owner’s-only hull. If you do, there’s a separate heads and shower, desk, seating and storage. Outremer makes much of the boat’s quietness, free from the grinding and cracking noises you hear as some cats flex. For liveaboards this could be a welcome feature.

First impressions

Outremer has done an impressive job of updating its most popular model, outside and in. I like the modern, muscular look of the sculpted-out topsides and dreadnought bows. Improved build techniques – partly acquired since its takeover of Gunboat – have also allowed the yard to save 600kg over the original model. The 51 has enough of a go-faster appeal for those converting from performance monohulls – the majority of Outremer’s clients, says sales manager Matthieu Rougevin-Baville – while at the same time retaining the seaworthy build and features for which the brand is known. It’s about keeping things simple, good-looking yet durable. For those with the budget, this is the ideal size of boat, in terms of speed bought by long waterline length, volume for accommodation and payload capacity (3 tonnes), for long-term, fast bluewater sailing.

LOA: 51ft 3in (15.65m) Beam: 24ft 4in (7.42m) Draught: 3ft 1in-7ft 7in (0.94m-2.31m) Displacement: 13.7 tonnes Price: from €735,000 Contact: Catamaran Outremer

Just launched: Ocean Explorer 60

Rubbing shoulders with Nautor’s Swan in Jakobstad, Finland, the new team behind this boat have a long track record in building low-impact yachts with high performance. And it’s not just a postcode they share with Swan – German Frers is also the designer of this yacht. The OE60 is the first in a range running to 78ft. There is carbon  load-point reinforcing and an  all-carbon rig for performance, with the further option of a carbon hull as well. Cutter rigged with a self-tacking jib and staysail, it has a long, sculpted bowsprit for launching downwind sails. Dual helm stations on each hull have long clear views ahead.

I wrote about this catamaran during its conception five years ago, but La Grande Motte was the first time I had seen one. Wow, talk about worth the wait… this is quite simply one of the most impressive luxury multihulls I have been aboard. Four main subcontractors to Nautor’s Swan and Baltic Yachts formed the company and the quality of their craftsmanship is, as you would expect, world class. It is the first production cat for Frers, yet the Argentinian designer has managed to maintain his reputation for alluring lines – this is a long, low and particularly elegant design. I like the helms right in the quarters, a more familiar position for monohull sailors, while the glass-based coachroof allows the helmsman a reasonable sight to the opposite bow. Step inside and it is the true panoramic view these vertical windows all combine to give that really appeals. The forward cockpit is a practical area for manning halyards or standing watch. I also like the clean, spreader-less rig and massive yet practical stowage areas. The skipper told me he had sailed a Gunboat 60 across the Pacific and that this OE60 matches its performance. A key is the C-foils, the most reliable appendage system he has used. This was the second OE60 to be built (the first has done four Atlantic and one Pacific crossing in four years) and is being used for charter. What I’d give for a week aboard this…

LOA: 60ft 7in (18.50m) Beam: 29ft 8in (9.07m) Draught: 2ft 6in-6ft 6in (0.85m-2.00m) Displacement: 18 tonnes Price: from €3.6m Contact: Frers

Just launched: Seawind 1600

The new flagship performance cruiser from the Australian brand made a welcome world debut at La Grande Motte in April. The Reichel Pugh design sits in a similar market to the Outremer 51 – a fast composite cruiser, aimed at couples going long-distance cruising. The first six 1600s sold off plans and Seawind, which owns Corsair, now builds in Vietnam. All boats are built using vinylester and Diam foam. The 1600 is Reichel Pugh’s first production multihull and has a practical air about it that sailors will appreciate. “It has been properly designed to sail fast when loaded,” says Seawind sales manager Jay Nolan. The helmsman can steer from under the solid bimini or can stand outboard, with a good view over the low coachroof. Retractable, captive daggerboards, along with foam-cored lifting rudders in cassettes, allow true shoal draught capability. The daggerboards are housed underdeck and controlled from the cockpit. The running rigging is, unusually, led under the coachroof and bridgedeck aft to a single central winch on the aft crossbeam. Reefing lines and the self-tacking jib sheet also lead to this protected, vertically mounted winch. The cockpit is smallish, linked to the interior via a huge sliding window.

I quickly took to this boat. The choice of performance monohull specialists to design a cruising cat is unusual, yet here the combination of Reichel Pugh’s reputation for winning lines and Seawind’s three decades of catamaran building experience has worked admirably. Sailors will appreciate the practical elements incorporated throughout. The design itself has particularly narrow hulls at waterline level, a low freeboard and coachroof, and the incorporation of a proper payload capacity into the light displacement. The use of captive boards and rudder cassettes allow for both sailing to windward and shoal cruising. The cassettes also create the option to replace  or repair a blade easily and the low coachroof allows proper forward visibility  from either helm. With the addition of larger portholes in the cabins, the 1600 gives an interesting fast cruising option for couples.

LOA: 51ft 8in (15.74m) Beam: 25ft 10in (7.90m) Draught: 8ft 6in-2ft 1in (2.6m-0.54m) Displacement: 13 tonnes Price: from €740,000 Contact: Seawind

Catamaran vs Monohull – Which is Better?

Which is better a catamaran or a monohull.

I’m often asked by my students why one would choose a sailing monohull or a sailing catamaran for their adventures. The simple answer is: There is no simple answer — it depends on a lot of things, perhaps the most important one is your preference. “Yeah, well, this is my first week sailing ever, so how do I have a preference?” Let’s explore the differences and discuss the ins and outs of sailing, chartering, performance, and living aboard either vessel.

Notice that I don’t say “pros” and “cons” when considering the differences between the two vessels. To some, the gentle rocking of the monohull elicits nostalgia for a bygone youth spent sailing dinghies in the bay. To others, it represents sleepless nights, banging kitchenware, and angry spouses.

Short Summary – Catamaran vs Monohull

Generally, I describe my preference as follows: If I want to invite guests that are not frequently on the water, have less tolerance for “bumpy” nights, or expect a more “luxury” experience (you’ll see why I put it in quotes shortly) then I select a sailing catamaran. There is more room to spread out (vs the same length mono), rocking at anchor/mooring is minimized, and the kids love playing on the trampoline. Or perhaps phrased differently, “If you want to drink from beach to beach…”

DO NOT DRINK ALCOHOL WHILE OPERATING ANY VESSEL. EVER.

If, however, you want to put some miles down sailing from port to port in the Med (or wherever you have variable wind direction), then the mono is probably the better option. It has better upwind performance and costs less in marinas.

Let’s get into the details. We’re going to compare a suitable, common charter catamaran ( Lagoon, 40 ’) with a good, common charter monohull (Beneteau, 41’).

Sailing and Performance

The monohull total tacking angle is about 90-100 degrees apparent wind angle (AWA). This means that the closest close-haul sailing angle achievable is approximately 45-50 degrees off the wind. The comparable catamaran has a total tacking angle of about 110-120 degrees (55-60 degrees AWA off the wind). This loss is due to the extra leeway experienced in the catamaran. This is a significant difference when trying to beat to windward and can mean the difference between sailing the entire distance vs putting the sails up for show only. For those interested in math, the progress into the wind is determined by the cosine of the close haul sailing angle (angle of the wind) times the length of the leg on that tack.

windward distance = cosine(𝜶) x leg length

Where α is the close haul sailing of the vessel. Table 1 compares the windward distance achieved of 3 sailing angles over a leg length of 1 unit (nautical mile, km, etc). For example, if the leg length is 1 nm, and 7 legs are sailed, a total distance of 7 nm is covered. However, the progress to windward is not 7 nm, but

cosine(𝜶) x leg length = cos(45°) x 7 nm = 0.71 x 7 nm = 5.0nm

for a monohull sailing 45° to the wind, and 4.0 nm for a catamaran sailing 55° to the wind. The final difference after 7 tacks each is 1.0 nm, which would take the catamaran an additional 2 tacks (and just shy of 2 nm distance sailed) to make up the difference.

Table 1. Sailing Angle and Distance Comparison Sailing Angle (off the wind) Windward Distance Achieved % loss from 45°

Figure 1. Sailing Angle Mono vs Cat

A real-life example

Sailing from Mallorca on a new Lagoon 40. We needed to sail directly upwind in about 20 knots of wind, 3 miles from Cala Mondragó to Cala D’Or. It took over 2 hours and we sailed over 7 nm. As you can see, the tacking angle is far from 90º typical to a monohull.

Additionally, the loss to each tack must be considered. Speed and headway is lost with each tack – the mono carries its momentum much better (minimal speed loss) through the tack and has minimal leeway loss compared to the catamaran. The cat loses a tremendous amount of its momentum and experiences significant leeway loss. And it has to take more tacks to make the same windward distance, rendering the loss greater than that just lost to having to sail a greater distance due to the tacking angle.

Daggerboards greatly reduce leeway and give catamarans excellent upwind performance on par with monohulls. There are reasons why all cats don’t just have daggerboards. Especially on charter boats, one mistake, leaving the boards down, in shallow water can destroy the boat.

Across the wind (most reaching situations), the catamaran is faster. Upwind, the mono makes better progress due to the tacking/sailing angle. Downwind is a competition.

Downwind is where catamarans really shine. The stability and smooth ride is no comparison to a monohull. We sailed Never Say Never, our Lagoon 400S2 from Hilton Head SC to Ft Lauderdale, we had a NE wind of 20-25 knots. For us to stay inshore of the Gulf Stream to avoid rough conditions, we were wing-on-wing for over 24 hours, surfing down gently at over 7 knots. We covered over 160 miles in 24 hours. Escorted by dolphins, this was one for the books —non-stop 3-day delivery.

Comfort & Stability

The catamaran doesn’t heel (well, it shouldn’t. I guess if that’s the case we’re having another conversation ). No heeling can mean easier walking about while underway: we’re all familiar with walking on level ground; walking with the ground at an angle is a less-common experience. However, there is an oft-missed discussion about the mono’s stability on a heel. Waves tend to roll under the mono’s hull. Once sea legs are found, the motion of the hull on the water is predictable and smooth.

The cat’s motion on waves tends to bounce between two “stable” states: one resting on the starboard hull, the other resting on the port hull. You get a slight, but sudden rock to starboard when the wave passes under the port pontoon, then a sudden return to port as the wave passes under the starboard hull. This tends to be a jarring motion all day. So while some argue that mono heeling is tiring, others will argue that this cat phenomenon is tiring. A sarcastic captain often says:

“One benefit of a cat, you get each wave twice!”

Each vessel has its own quirks for sail trim, so that is a wash. I can read a mono’s sails much easier than a cat’s, but I sailed monos for 20+ years before trying cats so I may be biased.

Catamaran vs Monohull Safety

The mono gives lots of feedback about being overpowered long before it becomes a problem: heel angle and weather helm are the loudest. The cat is much more subtle: mast and boom groans, light windward pontoon, lack of steerability. Experiment with the main traveller position and reefing on a schedule per the owners manual to find the optimum sail configuration on a cat.

When the seas pick up, catamarans do much better downwind. Monohulls tend to roll, yaw and wallow in the troughs and round up on the face of the waves. Catamaran’s tend to surf straight down the waves. A force 7-8 blow can be enjoyable. Stow your main and run with just the jib downwind on a cat and you’ll see the beauty and ease to steer this configuration.

“When the seas pick up, catamarans do much better downwind. Monohull’s tend to roll, yaw and wallow in the troughs”

Chartering and Living Aboard Considerations

Charter cost – cats are 30-60% more expensive than the equivalent mono.

In marinas, the cat rate is usually 50% greater than the mono rate. And, unless you get a reservation long in advance, they might not have room for you.

On moorings, depending on the bow cleat location, the mooring lines can run over or along portions of the hull of the cat. This leads to line stretch-and-relaxation noise all night long. For anyone in the forward cabins, this is a nightmare. Or worse since you can’t even get to sleep to have a nightmare.

Cats tend to have shallower draft and therefore can anchor closer to the beach. If wind and swell are from the same direction, cats tend to weather it better at anchor. Due to the bridle, cats do not swing on anchor. Older monos used to swing a lot, modern designs have reduced this swing tremendously.

There is lots more room on a cat to house the luxury amenities like A/C, water makers, and generators. Though, modern design is allowing for clever locations for these items in the mono, so there will probably be more monos becoming available with these options.

Cats tend to carry more potable water than the mono. They also carry more fuel. And burn more. Our weekly mono fuel bill ranges from $80-150 USD. Our weekly cat fuel bill ranges from $180-300 USD. (1.) Though you pay more for a catamaran, most systems are redundant. Two engines are better than one.

Catamaran vs Monohull Maneuverability

Cats are far easier to maneuver under power due to the two engines being separated by such a great distance. This makes picking up moorings, dropping and weighing anchor, and docking a breeze.

I would argue that monos are easier to manoeuvre under sail due to large rudders and heavy keels. The heavy keel maintains its momentum through manoeuvres much better than the cat. The large rudder means a small helm adjustment is quickly experienced in the respective heading. This large rudder also reduces steerage way to about 0.75-1.0 kts, whereas the cat is about 2.5 kts. While I doubt we’ll see cheaters , I mean bow thrusters, on 40’ monos, I have seen them on 44’ monos before. This added amenity makes up for greatly increased manoeuvrability while docking or weighing anchor.

Dinghy Storage

Storing the dinghy on the davits is a wonderful location for passages of any length. The reduced drag from not towing it is immediately seen in increased sailing speed. Monos must carry theirs on the bow or tow it astern. And you have to take the engine off too. Usually by hand, so you are not going to see a 20HP electric start engine on a dinghy for a 40’ mono. Not that you’d see that size for a 40’ cat either, but a 9.9 – 15 HP isn’t out of the question.

Ultimately, it boils down to what your preferences are. Do you like the extra space and amenities the cat provides? Do you like the sailing performance of the mono? Again, I choose a cat to sail from island to island in the Caribbean, where having a water maker or A/C is nice, fairly flat water is expected at all times, and anchoring close to the beach is a cool experience for everyone on board. I choose a mono to sail greater distances, go offshore, or hop from one marina to another in the Med.

Monohull vs Catamaran: A Deep Dive into Design and Performance

The genesis of two designs.

In the world of sailing, the debate between monohulls and catamarans is a tale as old as time. The history of these two iconic designs stretches back to antiquity, reflecting the evolution of human innovation and our insatiable desire for exploration.

The monohull's genesis lies in the early days of human seafaring. Traditional cultures from the Mediterranean to the South Pacific have all used some form of monohull craft for fishing, trade, and exploration. The monohull's sleek, single-hulled design, characterized by a deep keel and distinct bow and stern, offers an efficient shape for cutting through waves. Over centuries, the monohull design has been refined and perfected, culminating in the magnificent yachts we see gracing our waters today.

On the other hand, the catamaran, a vessel with two parallel hulls, boasts a legacy equally steeped in seafaring history. Its origins can be traced back to the outrigger canoes used by ancient Austronesian cultures.

The word 'catamaran' itself is derived from the Tamil word 'kattumaram', which loosely translates to 'logs tied together'.

These innovative sailors discovered that by adding a second hull, they could greatly improve the stability and speed of their vessels, a design principle that holds true to this day.

Exploring the Monohull Design

Stepping into the present, let's delve deeper into the modern monohull design. Its traditional single hull offers a quintessential sailing experience that's hard to match. Monohulls are typically seen as the embodiment of the romantic sailing ideal, thanks to their elegance and the graceful way they heel under sail.

One of the major benefits of monohulls lies in their seaworthiness. Their deep keels provide excellent stability, allowing them to handle heavy seas and high winds effectively. In addition, the keel acts as a counterbalance, enabling the boat to right itself after being heeled over by a gust of wind. This 'self-righting' characteristic is a significant safety feature exclusive to monohulls, adding a level of reassurance when navigating challenging sea conditions.

Monohulls are also known for their responsive handling and satisfying sailing performance. The mono-hulled design cuts cleanly through waves, resulting in a smooth and predictable ride. If you're the type of sailor who enjoys feeling the wind and waves' raw power, the visceral connection that a monohull provides is unparalleled.

However, as with everything in life, monohulls also have their downsides. For one, space can be at a premium. The deep keel and the rounded hull shape necessary for stability and performance take up much of the interior volume, leaving less room for living space compared to a similarly sized catamaran.

Another consideration is the heeling motion. While some sailors love the feeling of a boat leaning into the wind, others may find it uncomfortable or disorienting, especially during prolonged passages.

Despite these trade-offs, monohulls continue to hold their charm for many, offering a blend of tradition, performance, and adventure that has stood the test of time. In the next part of this deep dive, we'll shift our focus to the twin-hulled wonder of the sailing world: the catamaran.

The Catamaran Conundrum

As we switch gears to catamarans, it becomes apparent how contrasting they are to their monohull counterparts. Catamarans, with their dual hulls connected by a central platform or cabin, present an entirely different set of strengths and challenges.

Let's start with one of the most prominent features of catamarans: their stability. The wide beam of a catamaran provides a significant increase in stability over a monohull, reducing the boat's tendency to roll. This stability not only enhances the comfort of your crew but also allows for safer and easier movement on deck and below. If the notion of preparing a meal in a level galley while underway appeals to you, a catamaran might be the perfect fit.

Space is another major advantage of catamarans. With essentially two hulls worth of volume, catamarans typically offer much more living space than a similarly sized monohull. This makes them an attractive option for those planning extended cruises or living aboard. The additional space also allows for separate, private cabins in each hull, perfect for accommodating families or groups.

When it comes to performance, catamarans have a distinct edge in certain areas. Their dual-hulled design and lack of a ballasted keel result in less drag, allowing them to often outpace monohulls in moderate conditions. However, this speed advantage may be offset in heavy weather, where the ability to cut through waves (rather than ride over them) can make a monohull's ride smoother and faster.

But, just like monohulls, catamarans aren't without their drawbacks. While their stability and flat sailing characteristics are often seen as benefits, they can also create a false sense of security, leading some sailors to push their boats beyond safe limits. Additionally, while catamarans are significantly harder to capsize than monohulls, if they do flip, they generally won't self-right like a monohull would.

Furthermore, catamarans can be more challenging to handle in confined spaces due to their wider beam. Docking, in particular, can be trickier, especially in marinas designed with narrower monohulls in mind. Also, the increased beam and dual hulls often lead to higher mooring and maintenance costs.

Monohull vs Catamaran: Performance Parameters

Before we take this deep dive to its conclusion, it's important to touch on a few key performance parameters. These can greatly influence whether a monohull or catamaran would be a better fit for your sailing needs.

For starters, how a boat handles various wind conditions is critical. Monohulls, due to their keeled design, tend to excel upwind. Their ability to 'point' into the wind is usually superior to that of a catamaran. On the other hand, catamarans, with their lighter weight and reduced drag, often have the upper hand in downwind and lighter wind conditions.

Another factor to consider is load carrying capacity. While catamarans have more space for storing gear and provisions, they can be more sensitive to overloading. Additional weight can significantly impact a catamaran's performance, whereas monohulls tend to be more forgiving in this regard.

In the final part of this blog, we'll wrap up our deep dive by considering these and other factors to help determine which design might be the best fit for your sailing needs.

Choosing Your Vessel: What Suits Your Sailing Style?

Now that we’ve explored the design principles and performance traits of monohulls and catamarans, it’s time to consider what kind of vessel will best cater to your personal sailing needs and preferences.

If your sailing plans involve long passages in open waters, especially in rougher seas or challenging wind conditions, a monohull's sturdy and seaworthy design might be the most fitting choice. Their excellent upwind performance and smoother ride in heavy weather will provide you with both comfort and safety on lengthy oceanic voyages.

For those attracted to the exhilaration of speed, catamarans, with their swift downwind capabilities, can offer a thrilling sailing experience. They can be the ideal choice if your sailing adventures are primarily focused on coastal cruising, island-hopping, or participating in sailing races where their speed advantage can shine.

Lifestyle preferences play an essential role as well. If you value space and comfort, and perhaps are contemplating living aboard or planning extended family cruises, the spacious interior of a catamaran, with its level sailing and private cabins, may be the superior option.

Monohull boats offer several advantages that make them popular among sailors.

One of the key advantages is their excellent seaworthiness, particularly in challenging conditions. The deep, V-shaped hulls of monohulls provide stability and a smoother ride through waves and choppy waters.

This design allows monohulls to cut through the water efficiently, making them well-suited for offshore sailing and bluewater cruising.

When out in huge waves during an unexpected storm I found it hard to imagine how a catamaran would cope compared to our heavy bluewater monohull that just plowed through the waves as though they were butter.

Another advantage of monohulls is their superior upwind performance. The single hull design allows them to tack more effectively and maintain a higher pointing ability, making them ideal for sailors who frequently navigate against the wind. This advantage is particularly important for racing sailors and those who enjoy exploring areas where upwind sailing is common.

Monohull boats are typically more maneuverable than catamarans. The single hull allows for sharper turns and greater agility, which can be advantageous in tight spaces, marinas, or when docking.

The ability to maneuver easily makes monohulls more versatile in navigating narrow channels, entering small harbors, or handling in confined areas.

Additionally, monohulls offer a wide availability and variety of models, sizes, and configurations. They have been the traditional and widely available choice in the boating industry for a long time. This abundance of options allows boaters to select a monohull that suits their specific preferences, needs, and budget.

It’s important to note that the choice between a monohull and a catamaran ultimately depends on individual preferences, intended use, and specific requirements. Both types of vessels have their unique advantages and considerations, and it’s crucial to carefully evaluate these factors when selecting a boat that best suits your needs.

Catamarans, despite their advantages, also have some disadvantages that should be taken into consideration.

One notable disadvantage is the cost. Catamarans are generally more expensive than comparable monohull boats. The construction, materials, and design complexity of catamarans contribute to their higher price tag.

Additionally, maintenance, docking fees, and insurance costs can be higher due to the larger size and wider beam of catamarans. We’re only just starting to find out just how much more they cost, and it isn’t insignificant!

Another disadvantage of catamarans is the limited availability of berthing options. The wider beam of catamarans can pose challenges when it comes to finding suitable berths in marinas. Many marina slips are designed to accommodate monohull boats and may not have sufficient space for catamarans.

This limitation may require catamaran owners to seek specialized marinas or rely more frequently on anchoring.

The wider beam of catamarans can make maneuvering more challenging, especially in tight spaces, narrow channels, or crowded marinas. The increased width may require additional care and skill when docking or navigating in confined areas. Catamarans may also require specialized docking arrangements or wider slips to accommodate their size.

In heavy weather conditions, catamarans may experience some performance limitations. While they generally provide excellent stability, their wider beam can make them more susceptible to windage and slamming.

The larger surface area exposed to the wind can result in more resistance and difficulties maintaining course in strong winds. Skillful handling and careful sail management are necessary to optimize performance in challenging weather conditions.

Additionally, some sailors enjoy the heeling sensation experienced on monohulls when sailing close to the wind. Catamarans, with their stable platform, lack this sensation since they do not heel to the same degree.

This absence of heeling can be seen as a disadvantage for sailors who enjoy the dynamic experience of monohull sailing.

a monohull vs catamaran anchoring deeper

Monohull boats also have their own unique set of disadvantages.

One of the main disadvantages is their stability compared to catamarans. Monohulls typically have a narrower beam and a single hull, which can make them less stable in certain conditions, particularly in rough seas.

This may result in more rolling and pitching motions, which can be uncomfortable for some passengers.

Another disadvantage of monohulls is their potential for heeling. When sailing close to the wind, monohulls have a tendency to heel or lean to one side. While this is a characteristic appreciated by many sailors, it can be a disadvantage for those who prefer a more stable and level sailing experience.

Monohulls also tend to have limitations when it comes to living space and interior layout. The narrow beam of monohulls can result in smaller cabins and reduced interior space compared to catamarans. This can be a consideration for individuals or families looking for more spacious accommodations on their boat.

Additionally, monohull boats may have more limited access to shallow or restricted areas due to their deeper draft. The single keel design of monohulls often requires a deeper depth requirement, which can limit their ability to explore certain cruising grounds or navigate shallow waterways.

Lastly, monohull boats generally have a lower initial stability when at rest compared to catamarans. This means that while they may have better stability underway, monohulls can feel less stable and more susceptible to rolling when anchored or at the dock.

This may require additional measures such as stabilizers or careful weight distribution to enhance stability at rest.

When it comes to determining which is better in rough seas, whether a catamaran vs. a monohull, it depends on various factors and personal preferences.

Both types of vessels have their own strengths and considerations in rough conditions and it took us a lot of research to work out that really there isn’t a ‘better vessel’, just different preferences.

Catamarans, with their wide beam and twin-hull design, generally offer better stability and reduced rolling motion in rough seas. The separation of the hulls provides a larger base and increased resistance to rolling, resulting in a more stable platform.

This can contribute to a smoother and more comfortable ride, particularly in waves or when the sea state is challenging.

The inherent stability of catamarans can also be advantageous when sailing in rough seas, as it reduces the tendency to heel excessively and maintains a more level deck. This can enhance safety and comfort for crew and passengers, as well as provide better accessibility to onboard amenities and reduce the risk of items shifting or falling.

Adam and I have always found that the constant rolling on our monohull caused lots of opportunities for accidents, and even sometimes prevented us from checking things on deck because we felt too unsafe to move around up there in heavy seas.

On the other hand, monohulls are known for their ability to handle rough seas and heavy weather conditions effectively.

Their single hull design, with a deep keel and ballast, allows them to slice through waves and provide a more predictable motion in challenging sea states. The weight and ballasting of monohulls contribute to their ability to maintain course stability and resist being pushed around by waves and wind.

Monohulls also have a reputation for their ability to “self-right” in extreme situations, where their inherent stability helps them recover from a knockdown or capsize. This characteristic can provide added safety and reassurance in rough seas.

It’s worth noting that the specific design, size, construction, and condition of a vessel can significantly influence its performance in rough seas.

Heavy weather sailing often requires proper preparation, including reefing sails, securing loose items, and ensuring the boat is seaworthy and equipped with appropriate safety gear.

Additionally, the skill and experience of the captain and crew play a crucial role in handling a boat in rough seas. Understanding the vessel’s limitations, practicing good seamanship, and making sound decisions based on prevailing conditions are vital regardless of the type of boat.

Which Makes A Better Liveaboard Sailboat?

Monohulls also offer advantages for liveaboard sailing:

Sailing Performance: Monohulls are known for their sailing performance, particularly upwind. They typically have better windward ability and can handle a wider range of sailing conditions. If sailing and performance are priorities, a monohull may be preferred.
Cost: Monohulls generally have a lower purchase price and maintenance costs compared to catamarans of similar size and condition. This can be advantageous for those on a tighter budget or looking to minimize expenses.
Traditional Experience: Many sailors appreciate the traditional experience of sailing a monohull. The heeling sensation and close connection to the water can provide a sense of adventure and immersion in the sailing lifestyle. We have to say, we loved the romance that living on board our monohull gave.
Docking and Marinas: Monohulls generally require narrower slips, making them more suitable for certain marinas and docking situations where space may be limited. This can provide more flexibility in choosing berthing options (and cheaper too!)

Ultimately, the choice between a catamaran and a monohull as a liveaboard sailboat depends on individual preferences for space, comfort, stability, performance, budget, and intended use. Check out the best shallow draft liveaboard sailboats .

We would recommended you spend time on both types of boats, perhaps through charters or boat shows, to experience firsthand their layout, handling, and suitability for living aboard.

If you can’t do this, then we would suggest you buy a cheap boat to start with and spend six months living aboard to work out what you really want and need from a liveaboard boat.

Consulting with experienced liveaboard sailors can also provide valuable insights and perspectives based on their own experiences, and watching sailing YouTube channels can also help you form an idea of what you might need.

Conclusion: Catamaran Vs. Monohull

In conclusion, the choice between a catamaran and a monohull depends on various factors and personal preferences. Both types of sailboats offer distinct advantages and considerations.

Catamarans excel in areas such as spaciousness, stability, and comfort. Their wide beam provides ample living space, and their twin-hull design offers inherent stability, making them popular choices for liveaboard sailors seeking a comfortable and roomy living environment.

Catamarans also have advantages in terms of maneuverability, fuel efficiency, and shallow draft capabilities.

Monohulls, on the other hand, are known for their sailing performance, particularly upwind. They offer a traditional sailing experience with a heeling sensation and a closer connection to the water.

Monohulls generally have lower purchase and maintenance costs compared to catamarans, making them more budget-friendly options. They can also be advantageous in certain docking situations and marinas that have narrower slips.

It is important to consider factors such as space requirements, stability preferences, sailing performance, budget, and specific cruising plans. It is advisable to spend time on both types of boats to gain firsthand experience and insights into their handling, comfort, and suitability for specific needs.

Consulting with experienced sailors, attending boat shows, and seeking professional advice can also provide valuable guidance in making an informed decision.

Ultimately, selecting the right sailboat, whether a catamaran or a monohull, is about finding the vessel that aligns with your preferences, lifestyle, and goals for the sailing experience.

Catamaran Or Monohull? 27 Important Facts (Explained)

Catamarans and monohull boats are two very different kinds of vessels. Each craft offers distinct advantages and disadvantages that you’ll want to consider before choosing between the two.

In this post, we’ll go over some of the important things to consider when choosing between catamarans and monohull boats:

Table of Contents

Cost & Availability

Both catamarans and monohull boats come in small recreational sailing versions, larger motorboat versions, and larger sailing models. In all cases, the catamarans will cost more and will be harder to find.

The reason catamarans are harder to find because there are not as many of them, and they’re mostly made overseas.

Also, there aren’t as many catamaran manufacturers, so sailors have fewer options when buying them.

On top of this, catamarans have only recently become popular in the United States and other areas of the developed world. This means the used market for boats doesn’t have as many catamarans on it. You might find that you have fewer options when making a used catamaran purchase, which could bring costs up to a premium.

Two Times The Fun with Catamarans

Another reason that catamarans are more expensive than monohulls is the fact that catamaran buyers have to purchase two hulls, two engines, and two of all of the components that help make an engine work.

Traditional sailboats and large powerboats with one engine don’t have this cost issue.

On top of this, a catamaran is much wider than a monohull, and thus you have more space to build and equip.

On the other hand, once you’ve purchased the boat, you do get to enjoy the benefits of having two of everything. We’ll talk about the advantages of this further down in this post.

Maintenance Cost Makes A Difference

The maintenance on a catamaran is also more expensive than the maintenance on a monohull boat. This goes back to the fact that there is twice as much of everything to maintain.

Catamaran owners will need to do preventative maintenance on two different engines, and they’ll have two hulls and a large deck area to clean and maintain as well. If they’re getting the bottom of the boat treated, they’ll have to do this twice (once for each hull).

Even the interior components can usually be found twice.

Each cabin will usually have a head in it, so you’ll have at least two toilets and sinks to maintain, which obviously has its plusses and minuses.

One positive aspect of this is that catamaran owners do have the option of deferring some of their maintenance. For example, if one head is no longer functioning properly, you always have the second one that you can use.

It also adds a bit of safety as well.

This is because while the catamaran does have two engines to maintain, the owner does have power even if one of the engines happens to go down.

Some catamaran owners also like to point out that maintenance may not have to be done as frequently. This is because the engines don’t have to work quite as hard, and other items like additional bathrooms and sinks might only be used half as much.

How Much Space Do You Need?

A catamaran has more space than a monohull. This is because the boat is wider, and it has a much larger deck area. It also has twice as many hulls, so you have more overall space between the two of them.

The additional space is great for people looking to throw parties on their boats.

Most boat owners would agree that the catamaran is usually the party boat of choice at the docks.

Even if you aren’t into throwing parties, the extra space can still be nice for relaxing on the deck or getting a suntan. The wide-open space also makes it easy to use the boat as a fishing platform.

Additionally, you have more space for stuff like surfboards, rafts, and other items that can easily clutter up the deck of a monohull. Even fishing can be easier from a catamaran as the deck provides plenty of space between different anglers.

Catamaran owners also have additional space for carrying fresh water and adding generators and solar panels.

Interior space is generally more plentiful on a catamaran, and luxury catamarans have an easier time fitting large items like washers and dryers inside of them. You can have these on larger monohulls as well, but it will be harder to make them fit than it is in a catamaran.

On the other hand, all of the additional space means the catamaran owner has more space to maintain and clean. Also, all of the additional items that can be brought onto the boat will make it heavier. A heavier boat will use more fuel, and it will travel more slowly.

Living Quarters Vary Between The Two

The living quarters on a catamaran are much different than they are on a monohull. Most people would agree that the berths in a monohull are much more spacious than in a catamaran.

A monohull offers people the opportunity to have a large bed with space on either side to walk around it. This is great for couples who want to get out of bed without waking up their partner.

Catamarans, on the other hand, have the advantage of being able to offer large above-deck salon areas. The galleys, the dining areas, and the living areas can all be above-deck, while the two hulls can provide heads and berths.

Some boat owners say that living in a monohull is akin to living in a basement apartment . Other boat owners prefer the monohull because it brings them closer to the water and gives them the feeling of being at sea.

Privacy Can Be Prioritized On Catamarans

A catamaran offers up many different living areas that people can take advantage of. For example, each hull will typically have its own bathroom and bedroom.

This gives each sleeping area complete privacy from the other.

The living quarters are usually up on the deck, so early risers can wake up and move to these quarters without waking up the others.

The same holds for night owls. A night owl can stay up late without bothering the people who want to retire to their beds earlier.

With two hulls, large catamaran owners can hire a crew and give them their own hull to live in so that there is separation between the cruisers and the crew. This is a wonderful advantage for honeymooners looking to have their own space.

The downside to all of this, of course, is that sometimes a family may not want the additional privacy. For example, a family with small children might not want their children in a different hull than they are.

Additionally, the extra privacy can make it hard for people on the boat to communicate. This could become a big problem in the event of an emergency.

For this reason, it is often recommended that each hull have a radio in it so that the occupants can quickly communicate with each other. Remember, even in inland areas, cell phone reception may not be very good inside the boat hulls.

Recreation In a Monohull vs. a Catamaran

Most sailors agree that sailing a monohull boat is much more exhilarating than sailing a catamaran. Traditional sailboats heel, and sailors get instant feedback while they’re sailing. For the most part, catamarans stay stable, and you don’t get the same feeling with the movement of the wind and the water.

When it comes to monohull powerboats, you have the advantage of being able to pull water skiers, kneeboarders, and tubers with ease, as long as the boat has the power and a planing hull. A power catamaran usually doesn’t have the speed or maneuverability to pull off these recreational opportunities because they are displacement hull designs.

Catamarans excel in more leisurely recreational activities. A catamaran makes a great party deck as well as a great cruising deck. Catamaran owners can comfortably walk around a catamaran without having to worry that the boat might knock them over the next time it decides to heel. This allows boaters to sit and talk with one another comfortably.

A catamaran can also be used as a beaching vessel. This makes it a great platform for people looking to go swimming or fishing around sand bars and other shallow water areas. It also makes it a great boat for sailors looking to sail a larger boat on a river or lake known for having shallow areas.

Swimming and Diving

Swimming and diving off of a catamaran are usually much easier than doing the same from a monohull. The wide stance of the two hulls offers boat designers the option to put in staircases at the back of both hulls.

In between these staircases, some boats will have an additional diving platform and/or a dedicated frame for pieces of equipment and dinghy storage. This makes catamarans great for swimmers, snorkelers, and divers.

On the other hand, modern monohull sailboats can also have good transom stairs for easy access to the dinghy and swimming. Both types of boats can easily travel far out to sea, giving boaters the option of diving in areas that can’t be accessed from beaches and developed areas.

Boat Draft In Shallow Waters

For the uninitiated, the boat’s draft refers to how deep the boat’s hull sits within the water.

A monohull typically sits deep within the water, while a catamaran sits much higher on the water. This is why we stated that a catamaran is good for shallow waters.

The advantage of having a boat that can go into shallow waters isn’t restricted to just recreational activities like swimming and fishing. A boat that can go into shallow water is safer to operate in areas where a boat with a deeper draft might become damaged.

Additionally, a catamaran has more stability on calm waters. This helps make a catamaran more comfortable to relax or sleep on while at anchor or the dock.

The deeper draft of a monohull boat has its advantages as well. A deeper draft provides more stability in rough waters and allows a boat to go further into the sea.

For this reason, many coastal cruisers will prefer catamarans, while many ocean voyagers will prefer monohull boats. In fact, some areas of the Caribbean and the Florida Keys can be off-limits to boats with deep drafts as it simply isn’t safe for the boat to navigate these waters.

This isn’t to say that you can’t navigate these waters in a monohull boat, but you will have to be cautious depending on how deep your monohull’s boat draft is. You wouldn’t have this issue in a catamaran.

Stability On The Sea

A catamaran offers a lot more stability in shallow waters, in calm waters, at the dock, and anchorage. This makes the boat great for cruising and for relaxing in port.

A monohull offers a lot more stability in rough waters.

This makes this boat great for heading out to sea and for navigating vast distances.

Safety Issues To Consider

Both catamarans and monohulls can be built to navigate the waters they were made for safely. This will be determined more by the boat’s category designation rather than the type of boat.

However, each boat deals with unsafe situations in different ways. For instance, a monohull boat is likely to right itself if it is capsized.

This means that even in rough seas, you’re unlikely to find yourself permanently capsized.

The downside to this is that should you become completely swamped from a capsize in a monohull boat, you are much more likely to sink. In fact, if there is a hull breach on a monohull boat, your boat could sink.

Catamarans are said to be unsinkable. This isn’t completely true, but it is very unlikely that a catamaran will sink. Even if a hull is breached, you still have a second hull to keep the catamaran afloat.

However, a catamaran can’t right itself. If you capsize your catamaran, it will stay capsized.

One other safety concern to consider is that a monohull sailboat will heel while a catamaran will not. This increases the chances that someone could fall off the boat or onto the deck in a monohull boat.

Catamarans Are Faster Than Monohull Boats

A catamaran is faster than the average monohull boat.

This is because they face less water resistance, and their narrow hulls don’t have to deal with their own bow waves as a monohull does.

Of course, catamarans aren’t always faster. Old cruising catamarans may not go faster than 8 knots, and modern monohulls can exceed 10 knots.

Monohull boats tend to sail downwind and in choppy seas better than catamarans. This gives them a speed advantage during ocean voyages.

We have a separate post with complete average speeds per type of catemaran . It’s a must read if you are at all concerned about speed!

Fuel Consumption Considerations

Catamarans have two engines to burn fuel, which can drive up fuel costs.

However, a catamaran is lighter on the water, so it usually takes less energy to move a catamaran. This means you’ll end up using less fuel in a catamaran than you would in a monohull.

On top of this, catamarans can decide to use just one engine in low wind areas. This further decreases the amount of fuel that a catamaran consumes.

These rules only apply to calm waters.

A monohull navigates waters with high waves and strong winds much more efficiently than a catamaran. In this case, you’ll use less fuel in a monohull than you would in a catamaran.

Sailing Differences To Notice

Sailing a monohull boat can be exhilarating. These boats can glide through choppy waters, and you get to feel the motion of the boat as the sea rushes by the cockpit and the wind causes you to heel.

This type of sailing also provides instant feedback as you’ll know what you need to do with the sails as you’ll feel what is going on through the boat’s motion.

Sailors all over the world have been using monohull sailboats for years, and you’ll find plenty of outlets for recreational sailing with a monohull sailboat.

Sailing catamarans do not heel like a monohull sailboat.

These boats, therefore, do not provide the sailor with instant feedback. Also, if you incorrectly sail a catamaran, you do risk capsizing the boat more easily.

Training Can Be Quite Hard

Sailing a catamaran and sailing a monohull boat are two different experiences. People looking to sail either should probably get professional training.

Obtaining this training will always be easier with a monohull boat.

This is because monohulls are more popular, so you’ll have more instructors available to you.

Do You (Or Your Friends) Get Seasick?

People who are prone to getting seasick easily might want to consider a catamaran. A catamaran provides much more stability in calm waters, and you get a lot less movement.

On the other hand, people who are not prone to getting seasick might prefer a monohull in choppy waters.

This is because a monohull will deal with deep and choppy waters with high waves much better than a catamaran will.

As a result, a catamarans movement can seem extreme under these types of conditions. People who have never gotten seasick before can end up sick under these conditions.

Here’s a separate article we wrote with everything you should know about seasickness on Catamarans . There are some things you can do and some things you should know!

Docking Is (Usually) Easier With A Monohull Boat

Docking a catamaran can be a difficult endeavor.

This is because catamarans are often too wide to be docked within the slips located in central areas of a marina.

Because of this, they need to be docked at the end of the dock. This leaves them with fewer spots to dock. It also makes docking more expensive.

Catamaran owners traveling through areas that are unlikely to have many catamarans in them may find it difficult to find a dock at all. This is true in areas of the northern Atlantic where monohulls are much more popular than catamarans.

Storage Issues To Consider

Even storing a catamaran can be more difficult. This is because storage facilities often do not have the equipment to get a catamaran out of the water.

The wide width of these boats requires special lifts, and not all boat marinas will have them.

Storage facilities that do get the catamaran out of the water will often charge more money for it. They’ll charge additional fees for taking the catamaran out of the water, and they’ll charge additional fees for the actual storage of the boat as well.

Redundancy And Backup Equipment

We touched upon this earlier, but it is worth repeating that catamarans have many redundancy built into them. This can be a big advantage when it comes to safety.

For example, if one rudder becomes inoperable, the boat can still be steered with the other one. If one engine becomes inoperable, the boat can still be driven with the other one.

In extreme cases, a hull could become damaged, and you could still stay afloat because the other hull will keep the boat safely above water. These safety advantages can save lives and keep people from becoming stranded out at sea.

The primary downside is the maintenance issue that we mentioned earlier. All of these redundant components will need to be maintained. As a result, maintenance costs will be close to twice as expensive in a catamaran.

Cooking Is Easier On Catamarans

Cooking on a catamaran is usually easier than it is on a monohull. The main reason for this is that a catamaran doesn’t heel like a monohull, so you don’t have to worry as much about things falling over.

This not only makes cooking easier, but it makes cooking safer as well.

Additionally, catamaran galleys tend to have more space in them to move around. Also, they are often up on the deck, so you don’t have to climb in and out of the hull with your dinner in hand.

Dinghy Storage

Monohulls and catamarans can both hold dinghies. The larger the boat, the larger the dinghy can be.

However, catamarans have a wide area at the rear of the boat that is perfect for holding dinghies.

This makes getting in and out of the dinghy easier. Also, people can often have larger dinghies on their catamarans because the boat’s stern is so accommodating.

Power Generation Is Easy On A Catamaran

A catamaran has a lot of space for solar panels and wind turbines. Rigid panels can be placed in areas that won’t be walked on, like overtop of the bimini, and flexible panels can be placed in areas where the panels might end up getting stepped on.

The width of a catamaran even gives them more opportunities to put hydro generators into the water.

This means catamarans can generate more power than the average monohull boat can generate.

On the other hand, a monohull usually has less powered items to worry about. Monohulls need less power to operate at full capacity, so you may not need all of the additional space for generating power.

Ventilation Issues To Think About

Some people feel that monohull boats don’t offer enough ventilation. This is especially true in warmer areas of the world.

Catamarans also lack ventilation within their hulls, but fortunately for them, much of the living space is located up on deck. This gives catamarans an edge when it comes to cruising in warm weather.

On the other hand, monohull owners aren’t exposed to the cold winds that you might find up on deck in harsher climates.

This lack of airflow may actually be of benefit in this instance.

Some people find monohulls to be better looking than catamarans and vice versa.

This all comes down to personal preference, so you’ll have to decide for yourself which type of boat has the advantage in this case.

Some people think catamarans are the most elegant thing in the world while others prefer monohull boats as they look more classic.

Resale Value Is An Important Factor

If you read our extensive guide to boat depreciation per boat type , you know that no matter what boat you buy, it will always go down in value. This is just a sad fact of boat ownership that people need to consider before buying a boat.

Many factors go into how much you’ll be able to get for your boat when you resell it. These factors are the condition of the boat, the age of the boat, and the economy in general. For example, people are less likely to want to buy boats during a recession. This is especially true when it comes to smaller boats.

However, one additional factor that catamaran owners need to consider when thinking about resale value is the value of the dollar.

People from the United States don’t have many American catamarans to choose from and will usually need to buy these overseas.

This means that a catamaran will be less expensive to buy when the dollar is strong compared to the Euro and more expensive to buy when the dollar is weaker in comparison. This will affect the used market as well because higher values on new catamarans can help to bring up the value on the used market.

With a monohull boat, you may not have to consider situations like this as there are makers of monohull boats all over the world.

Don’t Let The Length Trick You!

One thought to keep in mind when comparing monohull boats and catamarans is that their different shapes account for different space advantages.

For example, a 40-foot long catamaran will have much more cubic space than a 40-foot long monohull.

Because of this, when comparing boats, you should look at the cubic space rather than the length. In this case, you may be comparing a 48-foot long monohull with a 40-foot long catamaran.

When you compare the two types of boats in this manner, the price differences aren’t quite as large, and the comparison is fairer. It also may make the operating and maintenance costs more similar.

This is an important distinction to make because the length of the boats can trick you!

Consider Trying Both (Before Buying)

Boats can be an expensive purchase, so it makes sense to try them out before you decide to make your purchase.

Rent each type of boat and use it on the types of waters that you intend to cruise on the most.

Try the boat out in different weather conditions as well, and don’t be afraid to do multiple rentals before you make your final choice. The time and money invested into making sure you get the boat you really want will be more than worth it in the end.

Catamaran vs Monohull: Why the Cat is Better for Your Sailing

We enjoy the extra lounge space a cat provides, especially a flybridge if available - that's where we'll spend most of our time during the day
We like the common areas being above the waterline and the better stability
We care less about sailing performance - we are the type of crew that is OK dropping sails if the winds are light or it's more convenient to motor
As the captain, I appreciate the maneuverability twin engines provide for docking - it keeps some stress out of the equation
Most tend to come with generators, AC, and water makers: all features we enjoy on these trips

Space & lounging

Sailing performance, maneuverability.

Catamaran vs. monohull, 12 comments:.

Great post! As you said, both types of sailboats are great ... they both take you out on the water! We love our mono-hull, but also appreciate the catamaran. We love the lean too!

Great piece. I've always heard cats are great for gunkholing around the Caribbean -not great for extended cruising. The reason being their poor performance and lack of comfort sailing upwind. Personally, I am only considering monohulls for a lot of the same reasons you cite.

It's an endless debate, but I'm with you, although you [b]MAY[/b] consider a cat when you start having grandchildren. Plenty of time before that happens, eh? Cheers! Tom

Mono has a better chance in Hurricane weather while at sea. Wind seems to make Cat and Tri Vessels Fly. Also heavy lead sinkers give a better motion to windward with weight inertia, in heavy seas and high winds. This coming from a 25 year 50foot Trimariner. I will be buying an under 36 foot leadballast Bluewater Mono Classic plasticfor my single handed senior years of liveaboard retirement this summer....with extended cruising planned.I have enjoyed both....just prefer one hull with lesser maint.to do....smile ! Thats what retired is about ...afterall!

Great post, as always. It's nice to be so sure of what you want, since searching for just the right boat is already fraught with layers of decisions. Looking forward to stories and pics of your little trio aboard the next adventure.

As always Brit, fun read. You forgot one vs. however; Cubs and Sox! Like your family and monohulls, I didn't know the American League existed until I was in high school! How much longer are you going to keep us waiting to see and hear about the new yacht?! Hope the sea trials are going well and she is all you hoped she would be.

Well said. Jeff and I are certainly on your same page with history (I too have memories of 'banana peel' on the low side with my brothers!). We have sailed mono hulls both with our families growing up and together for over 10 years... Some days I wonder why we are building a cat! Life is a learning experience, right? By the way, Isla is amazing... Some day it will be great to get our kiddos together on a beach, San Blas maybe? Xo. Abby

"We grew up heeling over on boats and surfing along on a tilt. That is what sailing is to us." You could have stopped with that statement. :) I think I understand your passionate desire and the way a monohull appeals to all of your senses. Sailing period gives my wife and I those same thrills. We own a monohull now which is lake bound in Texas and are one year away from buying what we call our phase two boat which will be a monohull. (We're looking at a 45' Morgan CC now.)Our ultimate goal is to end up on a Catamaran in the 44' range.(Something like a Fountaine Pajot or Leopard) I don't ever see us being able to afford the following boat but I have to say it is one of the prettiest cats I've seen. http://www.gunboat.com/ We are going into this as the boat is a means of getting to where we want to go so it has to be capable and comfortable. We know that a catamaran will be much more difficult to find marina berths or haul out for maintenance and that is why we are starting out with a bigger monohull. (Well that, and money. :) ) Love reading your blog and good luck on the new boat.

That's it, I'm canceling your dinner invitation on our cat. ;) Mike www.ZeroToCruising.com

Haha - Mike, ZTC doesn't count ;)

Hi guys, And, hi Mike from ZTC! Much debate and much fun to be had during these discussions! For another take on the subject, read my article "Catamaran or Monohull" in the April 2013 issue of All At sea Caribbean: http://www.allatsea.net/catamaran-or-monohull/ All the best and happy cruising, reading, writing and blogging (and raising the newborns! :-)), Liesbet SV Irie www.itsirie.com

I have been busy doing a lot of cat vs monohull research. I get very motion-sick, and have read that monohulls aren't good for people like me. Is this a problem for you? Thanks!

‍ Safety of Bluewater Catamarans

Cruising catamarans that are capable of bluewater sailing are some of the safest vessels on the water. In fact, they're often preferred for ocean crossing due to their miraculous speeds and excellent rough-water handling qualities.

Catamarans are uniquely equipped for safe and comfortable offshore sailing. They're not subject to the traditional limitations of hull speed, and they have a mild planing effect which reduces drag and the effects of rough seas.

Safest Catamaran Design for Crossing an Ocean

The safest ocean-crossing category is cruising catamarans, as these vessels include design elements and safety features that aren't found in recreational racing catamarans. An example of this is additional positive buoyancy material and watertight hatches.

Cruising catamarans have high-strength cockpit windows, which are designed to resist damage if a wave crashes on them. They also have redundant systems such as bilge pumps, navigation lights, and radios—which are all essential in an offshore voyage.

In fact, cruising cats are so safe that they're often recommended by expert sailors to more novice individuals. They aren't necessarily easier to sail, but they can handle rough weather safely and with better stability.

This keeps the crew dry and rational while the boat handles much of the ocean's beating all on its own.

Is it Safe to Sail a Catamaran During the Winter?

Catamarans can actually be safer to sail in winter weather conditions than monohulls. This is because cruising catboats almost always have enclosed cockpit spaces that are completely shielded from the elements. This is particularly helpful during the winter, but it's also a great feature in the tropical rainy season.

Catamaran crews can usually pilot their vessels from inside or behind these enclosed cockpits, keeping them warm and dry for as long as possible.

Additionally, given the premium nature of cruising catamarans, many of these vessels have automated winches and sails, allowing complete control from the interior cockpit.

How do Catamarans Handle Rough Weather?

Catamarans handle rough weather well, especially larger vessels with more displacement. But unlike monohull sailboats, draft and displacement aren't the most critical factors when evaluating foul-weather safety.

Catamarans are more difficult to swamp than monohulls. This is because they create a channel between their hulls that acts as a pressure relief valve, thus decreasing the likelihood of a rogue wave pushing the vessel under or knocking it over.

Catamarans are famous for their ability to weather high winds and chop. An equal-sized monohull may be just as strong and seaworthy, but the crew certainly wouldn't be praising its easy-riding qualities after a strong storm.

Catamaran captains are sometimes guilty of underestimating the danger or intensity of storms because a storm that beats the confidence out of a monohull crew may not even spill the coffee off the galley table in a catamaran.

Catamaran Buoyancy

Catamarans also have design elements that make them difficult—or nearly impossible—to sink. Or, to sink completely anyway. It's all about buoyancy, and catamarans have tons of it.

Monohull sailboats can handle well offshore, provided they have a low enough center of gravity and enough displacement to stay upright in violent gusts and large waves. Usually, monohull designers achieve this by working in an extremely heavy and deep ballasted keel.

In other words, offshore monohulls sit artificially low in the water due to added ballast for stability, both inside the cabin and deep in the keel. This is great until something starts to throw off-balance, like a bunch of water in the cabin.

Catamarans don't sit very low in the water because they're much more buoyant than monohulls and carry no large keels or ballast.

On their own, catamaran side hulls would probably roll over due to their lack of low ballast. But when strung together, they balance each other out and keep the hull far out of the water.

Catamarans don't often sink because they're simply too buoyant. They use their width and dual hulls to make up for the lack of ballast.

Plus, catamaran builders sometimes add additional positively buoyant material such as foam, to the point where sinking an intact vessel would be utterly impossible.

Are Catamarans Strong Enough for Ocean Sailing?

All production bluewater catamarans are extremely rigid and structurally sound. Catamarans make ocean journeys all the time and suffer tremendous stresses, which monohulls never experience. As a result, they're built using stronger materials and reinforced in all necessary areas.

Do Catamarans Break in Half?

It seems easy enough to believe—a catamaran hits a funny wave and breaks in half. After all, catamarans are only held together by a thin strip of fiberglass, right? Wrong—catamaran design is very robust, and all production catamarans are thoughtfully designed and strong.

Apart from the odd story in a sailing magazine, catamarans rarely just break in half. There have been some cases of it happening, but only due to extreme conditions, specific design flaws, or shoddy amateur construction.

Catamarans hulls break off far less often than regular monohulls sink—often in much less hazardous conditions than the few catamarans that did break in this way. So no, you don't have to worry about a production catamaran breaking in half while on the ocean.

Catamaran Comfort and Safety

Comfort can actually be a safety benefit on the open ocean, especially when sailing with a limited crew. Catamarans are known for their stability and increased motion comfort, which can improve the overall health and ability of the crew.

Think about it this way. A seasick and exhausted crew won't be able to deal with navigation or emergencies as efficiently and safely as a well-fed and well-rested crew. This is one of the indirect benefits that offshore catamarans have above most traditional monohull designs.

Catamaran Roll Safety

What happens if a catamaran suffers a knockdown? Usually, nothing good—catamarans can't self-right after a knockdown, unlike some monohulls with a low center of gravity. You're much more likely to have a knockdown or nail-biting roll on a monohull than a catamaran.

That said, catamarans don't suffer knockdowns nearly as easily as similarly-sized monohulls. This is because catamarans distribute their weight widely, and they have a much greater natural roll resistance.

Catamarans have great buoyancy in some parts of the hull and minimal buoyancy in others, which can actually increase roll resistance. For example, catamarans can slice through waves instead of riding over the crest and rolling violently.

It's not easy for the wind to push a catamaran down—quite the opposite. Catamarans actually rise out of the water slightly when sailed properly, even at angles perpendicular to the wind. Catamarans tend to increase in speed as wind speeds increase, directing more energy forward instead of to the side.

Monohulls have completely different high-wind handling characteristics. At some wind angles, high winds can push a monohull dangerously to one side. This is distinct from normal heeling, as the water can begin to rush over the deck and swamp the single-hull vessel.

Can Catamarans Survive Flooding?

Catamarans benefit from another safety feature that's not necessarily a design choice but a design element nonetheless. Catamarans are essentially compartmentalized, and they have a center cockpit high above the waterline.

These characteristics increase the amount of flooding necessary to seriously endanger the vessel. For example, a small leak in one hull needs to be fixed promptly—but it doesn't endanger the boat nearly as much as the same leak in your only hull.

Additionally, much of a catamaran's interior space is in the center console, which is above the waterline and thus can't be flooded from the hulls. Or at least not immediately. This is one of the reasons why catamarans rarely sink.

Catamaran Safety Equipment

Catamarans have a large amount of flat, open space between the hulls. These areas are useful for stowing equipment such as high-tech covered life rafts.

A small boat may have to make do with a small life raft and limited emergency supplies, yet a catamaran can store safety equipment for much larger vessels.

Catamaran Speed

Speed is an important and often overlooked aspect of safety, and we can use an example to demonstrate why. Picture two boats somewhere between Florida and the Bahamas. Dark clouds begin to form overhead, indicating a possible afternoon thunderstorm.

Boat A is a catamaran with good speed and sea keeping abilities. Boat B is a heavier monohull of the same length but greater displacement and technically better seaworthiness.

The catamaran, Boat A, deploys full sail and makes a speed of about 15 knots to outrun the forming storm. Boat B is a monohull and can't make more than 8 knots, even in the best conditions.

Boat A makes it back to port with time to spare, but Boat B is well out to see taking a beating from the storm. Speed means safety in many situations, even though it's never smart to try and beat the weather if you can stay in a safe location instead.

Monohulls vs. Catamarans: Which One is Best for You?

If you’re considering purchasing a sailboat, you might be wondering which type of vessel is best suited for your seafaring adventures. Fear not, for we’re here to help you weigh the differences between monohulls vs. catamarans to make an informed decision.

Now, before we dive into the nitty-gritty details of hull design, sail handling, and the like, let’s take a moment to appreciate the quirky personalities of these two boats. Sloop rigged monohulls are the classic, old-school sailboats with a single mast and a triangular sail. They’re like the wise old grandpa who’s been sailing the seas for decades and has plenty of stories to tell. On the other hand, catamarans are the younger, hipper cousins of the boating world. With their twin hulls and sleek designs, they’re like the trendy millennials who are always up for an adventure.

But enough with the stereotypes, let’s get down to business. In this article, we’ll explore the pros and cons of monohulls and catamarans across various factors such as stability, maneuverability, accommodations, and cost. By the end of it, you’ll have a better idea of which boat is best suited for your sailing style and preferences. So, hoist the anchor and let’s set sail!

What are classic monohulls?

Let’s start with the basics – what exactly are classic monohulls? Well, sloops. To put it simply, a sloop is a type of sailboat with a single mast and a fore-and-aft rigged mainsail. But there’s more to these boats than meets the eye.

Sloops are the OGs of the sailing world, tracing their roots back to the 17th century. They were the go-to boats for explorers, pirates, and adventurers alike, with their simple yet effective design making them perfect for long journeys at sea. Nowadays, they’re still a popular choice for sailing enthusiasts who appreciate the classic, traditional look and feel of a sloop.

One of the defining characteristics of a sloop is its versatility. They come in a range of sizes, from small day sailers to larger offshore cruisers, and can be easily handled by a single sailor. Their rigging is relatively simple, making them a great option for beginners or those who prefer a less complicated sailing experience. But don’t let their simplicity fool you – sloops can pack a punch when it comes to speed and performance upwind.

Of course, there are some downsides to monohulls as well. Due to their single-hull design, they can be less stable in high winds or rough seas. They also tend to have less living space below deck compared to their bigger brothers. But if you’re looking for a classic, reliable, and versatile sailboat, a monohull might just be the vessel for you.

What are catamarans?

Now let’s talk about the other contender in this seafaring showdown – catamarans. These boats are a bit like the cool kids in high school – they’re sleek, modern, and always turning heads.

So, what exactly are catamarans? Well, to put it simply, they’re boats with twin hulls that are connected by a platform. But don’t let their basic design fool you – these boats are anything but ordinary. Catamarans come in a range of sizes, from small day boats to luxurious yachts, and offer a unique sailing experience that’s hard to beat.

One of the biggest advantages of catamarans is their stability. With two hulls instead of one, they’re less likely to tip over or roll in rough waters. This makes them a popular choice for families or those who prefer a smoother sailing experience. They also have more living space above and below deck compared to monohulls, with spacious cabins, lounges, and kitchens that are perfect for extended trips.

But let’s not forget about performance – catamarans are no slouches when it comes to speed and agility. Their twin hulls create less drag in the water, allowing them to glide through the waves with ease. And with their sleek, aerodynamic designs, they can often outpace traditional monohull boats.

Of course, catamarans do have their downsides as well. They can be more complicated to handle compared to monohulls, and require more space to in marinas or docks. They also tend to be more expensive than other types of sailboats, but hey, you can’t put a price on luxury.

Hull design

Per definition, the hull design is the biggest differences between monohulls and catamarans.

Let’s start with monohulls. These boats typically have a single hull that’s shaped like a long, narrow tube. This design allows them to slice through the water with ease, making them great for speed and agility. The hull is usually rounded or V-shaped at the bow, which helps to cut through waves and reduce drag. At the stern, the hull flares out to create a wider, more stable base.

Now, onto catamarans. These boats have two hulls that are connected by a platform, giving them a unique look and feel. The hulls are usually wider and flatter than those of monohulls, which provides a greater amount of stability. This can be especially beneficial for those who are prone to seasickness or prefer a smoother sailing experience. The flat shape of the hulls also creates less drag in the water, allowing for higher speeds and better maneuverability.

When it comes to sailboats, stability is crucial for a comfortable and safe journey on the high seas. So, which type of boat – monohulls or catamarans – reigns supreme in this category?

Well, let’s start with monohulls. These boats have a single hull, which means that their stability comes from the shape and weight distribution of the hull. Generally speaking, monohulls tend to be less stable than catamarans, especially in rough waters. This is because the single hull has to work harder to maintain balance, and can be more prone to tipping or rolling.

With two hulls connected by a platform, catamarans are the kings and queens of stability. The twin hulls provide a wider base and more buoyancy, making them less likely to tip over or roll in rough conditions. This can be especially beneficial for those who are new to sailing or prone to seasickness.

Maneuverability

Let’s talk about maneuverability – the art of smoothly navigating your vessel through the choppy waters. When it comes to monohulls vs. catamarans, the level of maneuverability can vary depending on the design and size of the boat.

Starting with monohulls, these boats are typically designed for speed and agility, which can translate to better maneuverability in certain situations. Their narrow hulls and single keels allow them to slice through the water and make quick turns, which can be useful in tight spots or when navigating through busy marinas.

Now, onto catamarans. With two hulls and a wider beam, these boats can be more challenging to maneuver in tight spaces. However, they do have some tricks up their sleeves. For example, many catamarans have engines that can rotate 360 degrees, allowing for greater control and maneuverability in tight spots.

Of course, when it comes to maneuverability, the skill and experience of the captain also plays a big role. A skilled sailor can make even the most unwieldy vessel dance through the water with ease, while a novice may struggle with even the most nimble of boats.

So, whether you’re piloting a monohull or a catamaran, it’s important to keep your wits about you and stay alert to your surroundings. And if all else fails, just remember the time-honored sailor’s adage – “When in doubt, let it out!”

Accommodations

Starting with monohulls, these boats typically have a more compact interior layout, with limited headroom and sleeping quarters. However, this can be a trade-off for a sleeker and more agile vessel that can slice through the waves with ease. Plus, with some creative packing and organization, a monohull can provide all the basic amenities you need for a comfortable voyage.

With their wider beam and spacious design, catamarans offer more room for living and sleeping quarters, as well as additional amenities like a galley kitchen and a bathroom. This can make for a more luxurious and comfortable sailing experience, especially for longer voyages. In addition, the two-hull design offers more space on deck for dinner parties or sunbathing in the trampolines

Of course, when it comes to accommodations, everyone’s preferences are different. Some sailors may prefer the cozy intimacy of a monohull, while others crave the roominess and luxury of a catamaran. It all depends on your personal style and needs as a sailor.

Performance

Let’s delve into the topic of performance, which is a critical factor when selecting a sailing vessel. Each sailor may have a different perspective on what constitutes optimal performance, but generally speaking, it comes down to speed and efficiency.

When it comes to speed, catamarans have an advantage in downwind performance. Their wider beam and twin hulls give them more sail area and a greater ability to surf down waves, resulting in faster speeds. However, monohulls are often faster when sailing upwind, as their pointed hull allows them to sail closer to the wind.

The upwind angle is an important consideration for sailors, as it affects how close to the wind they can sail. sloop rigged monohulls are known for their ability to sail at a higher angle upwind, which can be a major advantage when sailing in areas with narrow passages or limited space to maneuver. Catamarans, on the other hand, may need to tack more frequently in order to reach their destination when sailing upwind.

Maintenance

When it comes to sailing, we all know that proper maintenance is key to keeping your vessel in tip-top shape. So, when it comes to choosing between a monohull vs. a catamaran, it’s important to consider the maintenance requirements for each type of vessel.

Monohulls generally have simpler systems and structures, which can make maintenance a bit easier and more straightforward. However, the tradeoff is that they may require more frequent maintenance and repairs due to their smaller size and simpler design.

Catamarans, on the other hand, can be more complex and may require more maintenance in terms of their twin hulls, rigging, and systems. However many important systems like engines, bathrooms, or water tanks are in both hulls which give you redundancy and options. Also, their larger size can make accessing and maintaining these components a bit easier.

Regardless of which type of vessel you choose, regular maintenance is a must. From checking and maintaining the sails and rigging to ensuring the engines and electrical systems are in good working order, taking care of your vessel will ensure that you’re able to sail safely and confidently.

When it comes to the cost of a sailing vessel, there are many factors to consider. Let’s take a closer look at how monohulls vs. catamarans stack up.

First off, monohulls are generally considered to be more affordable than catamarans, both in terms of the initial purchase price and ongoing maintenance costs. This is due in part to their simpler design and smaller size, which requires less materials and labor to build and maintain.

On the other hand, catamarans can be quite costly to purchase and maintain, especially if you opt for a larger or more luxurious model. The wider beam and heavier construction of a catamaran can also mean higher slip fees and storage costs at marinas. But don’t let that deter you! If you have the means and the desire for a more spacious and comfortable sailing experience, a catamaran might be worth the investment.

Of course, the cost of a sailing vessel is just one piece of the puzzle. You’ll also need to consider other expenses like fuel, insurance, and ongoing maintenance and repairs. And let’s not forget the most important cost of all: the cost of living your best life on the open sea!

So weigh your options carefully, and remember that the true value of a sailing vessel goes far beyond the price tag. May the winds of fortune guide you to the vessel of your dreams, and may you sail with joy and a full wallet!

Resale value

Resale value is an important consideration when it comes to buying any type of vessel, and monohulls and catamarans are no exception. Generally speaking, catamarans tend to hold their value better than monohulls due to their popularity among sailors and their reputation for being spacious and comfortable. However, resale value can also depend on the specific make and model of the boat, as well as its age, condition, and location.

Of course, there are always exceptions to the rule. Some monohulls may have a cult following and fetch a higher price on the resale market, while some older catamarans may not hold their value as well as their newer counterparts. Additionally, factors such as maintenance, upgrades, and customization can also affect resale value.

In conclusion, when it comes to monohulls vs catamarans, there is no one-size-fits-all answer. Each boat has its own advantages and disadvantages, and the decision ultimately depends on your personal preferences, needs, and sailing goals. If you have the money, looking for a faster ride downwind and don’t mind sacrificing a bit of upwind performance, a catamaran might be the way to go.

Resale Value

On the other hand, if you want something cheaper, prioritize sailing close to the wind and want a boat that is more easily handled in a variety of conditions, a sloop rigged monohull might be the better choice. Of course, other factors such as accommodations, and maintenance also play a crucial role in the decision-making process.

So whether you prefer the sleekness of a monohull or the stability of a catamaran, make sure to consider all the options and weigh the pros and cons carefully before making your final choice. And as with any big decision, it never hurts to consult with experienced sailors, boat dealers, or brokers to get their expert opinions. Happy sailing!
