Sailing a Daysailing boat that has one of the worlds largest racing classes

Thanks Dave. I agree. I raced on Scots and they perfectly fit the bill. Unfortunately they remain popular and really hold their value. But a Scot will top my list.

Dave, I just shot him an e-mail. That July end date is long gone, but I gave it a shot anyway. Definitely my price range. I'm willing to drive 2 hr. and fix two flat tires for a Scot! jim

Rhodes 19 with a keel? I don't know if it's self bailing or not, but I don't think the Flying Scot is either.  

I'm adding the Rhodes to my list. Lots of sailors love them. Lots of clubs have fleets. That's gotta be saying something.  

Barnacle Bill

I learned to sail on a Flying Scot. Can't say anything bad about them. Others: Rhodes 19 (stated already above), Precision 15 or 185, Tanzer 16, Lightning 19 and if cat boats are a consideration, there are many to choose from.  

B. Bill, Thanks for those suggestions--I'm adding them to my list. I know nothing of the Precisions nor Tanzer. If I spot a good deal on one locally now I'll know to check it out.

Ken does want a boat he can sit IN, not ON. The Mini ticks that box!

Especially for those cold northern waters you can't beat a Rhodes 19. They come in many configurations (keel, centerboard, etc.) and they are nice, forgiving, and safe small sailing boats. You aren't going to win any races (unless you are sailing against other Rhodes 19s), but I think they are just about the perfect 1st boat for many sailors. I also like the Colgate 26. Many consider the Colgate 26 to be absolutely the best value you'll find for a daysailer and racing keelboat in the 22 ' to 30' range. With her positive foam flotation and durable fiberglass construction, the Colgate 26 is unsinkable. But remember, that's what they said about the Titanic, too.

Colgate 26 just went on my list. Thanks.  

The Colgate 26 was designed by Jim Taylor for the Colgate sailing programs. Taylor designs attractive fast boats that are easy to sail. Designs by Jim Taylor Yacht Designs with Photos, Plans & Details

If you're considering a Colgate 26, have a look at a Soling, too. Most will be rigged with self-tacking jibs, and will likely come with trailers. (This makes winter storage quite simple.) Since they're no longer an Olympic class they can be found pretty cheaply all over the East Coast. They sail and handle beautifully, and will plane if you can get enough wind to make it happen.  

Thank you Dave and Capta. Colgate 26 and Soling now on my list. I used to see Solings sailing in Boston Harbor. Sailing school there used them. Lovely!

I'll throw in a good word for the MacGregor 26S (not to be confused with the X or the M). Pro's -Being a water ballast boat, it is very lightweight when trailering. 1650 lbs for the boat (with ballast tank empty) and 800 for the trailer, it trailers nicely behind my Dodge Grand Caravan. -Easy setup when using the gin pole with attached winch, or use your trailer winch with a mod I developed. I will send you the link if you are interested. -Full queen-sized berth under the cockpit - VERY few boats offer this. No tangling with the Admiral's feet like in a V-berth. Has sleeping space for five, but frankly I would three grownups is about the limit for overnighting. Four if you are really good friends. -Performs really nicely. I have taken first place in several races. -Very affordable. In good condition, they go for about $8000. If you are patient, you can probably find one for a lot less. -Points pretty well (though not as good as a J-boat, of course). With the airfoil rudder and decent sails, it points as well as the other boats I race against. -With the centerboard and rudder up, draws 1.5 feet. Great for shallow or unknown waters, and can be beached easily. Both the centerboard and the rudder kick up if you strike bottom, so grounding is far less a problem than fixed keel or swing keel boats. -Parts (and helpful advice from a knowledgeable source easy to find at bluewateryachts.com. -Self righting, and factory-installed flotation renders it practically unsinkable. -Active and helpful forum at macgregorsailors.com. Con's -Not a blue water boat -Will heel more than a fixed keel or swing keel boat I look at ads for other boats all the time, but I have yet to see a boat that I would rather own than my MacGregor 26S.

Ensign is a good boat. She’ll take care of you. But like a lot of boats mentioned here, not self bailing and not really trailerable. The OP did mention keeping the boat on a mooring so self bailing would be nice - not mandatory but nice. OP did not ask for trailer-ability.

The Ultimate Bug Out Boat: Living on a Self-Sufficient Sailboat for 10 Years

While I doubt I could willfully live for months or years on a boat like these folks did, I think the idea of a self-sustainable watercraft is an amazing idea for preparedness, and this boat clearly takes the idea of bugging out to a whole other level! Just think how awesome it would be to bug out to the ocean and avoid nearly everyone, especially when the SHTF?

In any case, their setup is really neat. They have communications (including satellite broadband internet), 1000-liter water storage and desalination equipment, hot water, freezers for food, solar and wind power (enough to power everything onboard), a nice kitchen and laundry setup, and more storage space then I would have guessed. Of course, if you’re not a very tidy or organized person then this probably isn’t going to work out for you.

A major drawback is all of the ongoing maintenance the boat seems to require. It’s not just an expense but a real problem if this were to be your main bug out option. Regardless, watch this and get ready to be jealous…

All three articles were quite interesting, especially the sailboat. I think that is the way to go. Providing you are completely prepared, of course. It sounds like they did everything correctly. I’d like to do it but I’d need an unsinkable ship. Not like the Titanic.

My neighbor and I each have land bound live aboard boats. My small fiberglass sailboat sleeps four [ugh!] His powerboat sleeps more. Each has electrical systems tied in to the grid, but they aslso have inverters and can use microwaves for cooking. The sinks are stainless, each will accommodate a water supply and sewage. Two hundred yards away is Lake Superior, thousands of fish.

Conclusion :

Choosing the best small sailboat under 20 feet when you are getting ready to sail ultimately depends on your preferences and sailing goals. The Hunter 17 offers a spacious cockpit and stability, making it an excellent choice for families and beginners. On the other hand, the O’Day Javelin focuses on simplicity and affordability, making it an accessible entry point into the world of sailing. Lastly, the Catalina 18 strikes a balance between performance and comfort, with the added bonus of a cabin for overnight stays.

Regardless of which small sailboat you choose, each of these options provides a unique sailing experience. Whether you’re seeking adventure, family sailing , relaxation, or a way to connect with nature, these boats have something to offer. So, set your sails and embark on your sailing journey with confidence, knowing that you’ve chosen one of the best small sailboats under 20 feet to accompany you on your maritime adventures.

Determining the absolute safest sailboat in the world is challenging, as safety can depend on various factors, including the crew’s experience, weather conditions, and maintenance. However, sailboats designed for offshore cruising, such as those from renowned manufacturers like Hallberg-Rassy or Oyster, are often considered some of the safest due to their robust construction and advanced safety features.

The most efficient sail shape varies depending on the specific point of sail and wind conditions. However, in general, an aerodynamically curved shape, similar to an airfoil, is often considered the most efficient for harnessing wind power and generating forward propulsion on a sailboat.

A sailboat size suitable for two people typically ranges from 20 to 30 feet, with 25 to 30 feet being a popular choice for couples. This size provides enough space for comfortable living quarters and maneuverability while still being manageable for a two-person crew.

The size of a sailboat that one can single-hand largely depends on the sailor’s experience, skills, and the boat’s design. Many experienced sailors can comfortably single-hand sailboats up to 35-40 feet, but with the right equipment and know-how, even larger vessels can be handled solo.

How Does A Self-Righting Boat Work? Life-Changing Approach!

A voyager who has ever encountered tremendous waves or heavy wind riding in a boat must have observed how a boat heels at one side but rolls back to the upright state. A self-righting boat is the most correct choice if sea conditions are so poor that heels exceed angles.

When external forces like heavy wind or large waves push a boat and cause it to incline in a direction, a boat tends to get back to its self-right position because of the buoyancy force that emerges from the underwater hull shape.

However, based on the design, a boat can not get back to its initial position anymore after reaching a maximum angle of heel. The only boats which tend to get back to their upright condition, even up to a 180-degree inclination, are called self-righting boats .

How Does A Self-righting Boat Work?

Mighty wind pressure or pushing from large waves causes a boat heeling. However, in spite of the inclination, a well-designed boat tends to return to its upright condition.

The self-righting boat rolls back to the upright condition because of the positive righting moment. The underwater portion of the vessel creates a buoyancy force that manages to roll back to its initial condition. A self-righting boat can roll back to the upright condition even after 180 degrees of inclination.

The gravity force pushes downwards and the buoyancy force pushes the vessel upwards. So, when these two forces are not in a line, a rotating moment emerges that actually causes the self-righting action of a boat.

Thus, falling in a mighty storm, a boat naturally rolls from one side to another and attempts to get back to an upright condition.

How Can A Lifeboat Right Itself?

A lifeboat can right itself because of its self-righting moment. The self-righting moment in a lifeboat develops from the gravity and buoyancy force. The principle of uprighting can be better explained in the two following diagrams.

Self-right boat diagram: Upright Condition diagram

In a normal upright condition, the gravity force (G) is due to the self-weight of the vessel, and the buoyancy force (B) is due to the underwater pressure acting in a line. In this condition, the righting moment is zero. When external forces cause the heeling of the lifeboat, the shape of the underwater volume changes as the healing occurs.

Thus, the acting position of the buoyancy force also shifts. So, gravity force (G) and buoyancy force (B) do not act in a line anymore. Consequently, the distance between the gravity line and the buoyancy line, which is called righting lever (GZ), increases.

Self-righting boat diagram

These two opposite forces cause a rotating moment on the lifeboat to right it back to the initial condition. The more is righting lever, the higher is the righting moment.

As long as the righting lever remains positive, the self-righting moment remains positive. This positive self-righting moment causes the lifeboat to roll back to the upright condition. 

What Does Self-righting Mean?

Self-righting boat means a boat that can roll back to upright condition by itself even after mighty external forces like wind and wave cause the vessel upside down.

The vanishing stability of a self-righting boat is almost 180 degrees. The vanishing stability is an angle up to which a vessel shows a positive self-righting moment.

What Makes A Boat Self-righting

A boat to be self-righting must have the righting moment positive up to 180-degree inclination, which means even after a vessel gets upside down because of heeling.

The keel of this type of vessel needs to be very heavy and usually occupies most of the percentage of the total weight. So, the vessel becomes unstable in the inverted state and rolls back toward the upright position.

Furthermore, the topside of this type of boat remains watertight so that the buoyancy force can act on the vessel even if the vessel is inverted.

Are Pilot Boats Self-righting?

Rafnar Cross Cabin SAR vessel - Example of the Self-righting boat

The boats that are used to facilitate the pilots’ transportation from one vessel to another are called pilot boats.

The capsize of the pilot boats is generally unexpected since they are usually considered self-righting.

However, in some cases, pilot boats have fallen in fatal and unexpected situations because of the steep waves of excessive heights and their direction of attack.

However, there are examples of the use of self-rightening pilot boats produced by Rafnar with ÖK Hull desi gn from Rafnar Professionals models .

Can You Right A Capsize Yacht?

There are several ways to upright a capsized yacht. The choice of the method depends on the wind and wave conditions you are sailing in along with the yacht’s capsized state.

If your yacht is capsizing in the direction of the wind blowing, release the mainsheet and tiller. Then, climbing over to the top edge of the yacht, step over the side deck to make the way up to the daggerboard.

Another method is the scoop method. In this method, a heavy person stands on the centerboard, and another person is picked up aboard. Furthermore, the main sheet and jib sheet need to be released to minimize the wind effect when the yacht is in an upright condition.

The traditional method is turning the boat in a way so that the bow and wind directions are along a line. In that state, one of your crew members should keep the boat towards the wind and another one should stand on the centerboard. Then the first crew should get on board from the stern side and pull the other crews as well.

When the vessel is in completely upside-down condition, the centerboard can be moved back into its position. In such a condition, you should stand on the gunwale and pull on a jib sheet and lean out so that the boat comes to the horizontal capsized position. Then adopt a suitable righting technique to bring your yacht to a completely upright state.

How Do Cruise Ships Handle Hurricane Season Cruises?

Thankfully, modern cruise ships can handle a hurricane season cruise. Due to past experiences and new advancements, crews prove these boats operate well no matter the weather.

M.B. Marsh Design

Understanding monohull sailboat stability curves.

One of the first questions people ask when they discover I mess around with boat designs is: "How do you know it will float?"

Well, making it float is just Archimedes' principle of buoyancy, which we all know about from elementary school: A floating boat displaces water equal to its own weight, and the water pushes upward on the boat with a force equal to its weight. What people usually mean when they ask "How do you know it will float" is really "How do you know it will float upright?"

That's a little bit more complicated, but it's something every skipper and potential boat buyer should understand, at least conceptually. (Warning: High school mathematics is necessary for today's article.)

A yacht at an angle of heel

Let's consider a boat at rest, sitting level in calm water. The boat's mass is centred on a point G, the centre of gravity, and we can think of the force of gravity as acting straight down through this point. The centroid of the boat's underwater volume is called B, the centre of buoyancy. The force of buoyancy is directed straight up through this point.

We now heel the boat over by an angle "phi". Point G doesn't move, but point B does: by heeling the boat, we've lifted her windward side out of the water and immersed her leeward side. The centre of buoyancy, B, therefore shifts to leeward.

The force of buoyancy, acting upward through B, is now offset from the force of gravity, acting downward through G. The perpendicular distance between these two forces, which by convention we call GZ, can be thought of as the length of the lever that the buoyancy force is using to try to bring the boat upright. GZ is the "righting arm".

If we draw a line straight upward from B, it will intersect the ship's centreline at a point called M, known as the "metacentre". (Strictly speaking, the term "metacentre" applies only when phi is very tiny, but a pseudo-metacentre exists at any given angle of heel.) The metacentric height is a useful quantity to know when calculating changes in trim and heel.

(Can't see the images? Click here for now , then go update your web browser.)

We can easily draw a few conclusions simply by looking at the geometry:

  • The boat will be harder to heel, i.e. more stable, if GZ is increased.
  • Lowering the centre of gravity, G, will increase GZ.
  • Moving the heeled centre of buoyancy to leeward will increase GZ.
  • If GZ changes direction- i.e. if Z is to the left of G- the lever arm will help to capsize the boat instead of righting it.

Stability Curves: GZ at all angles of heel

To prepare a stability curve, the designer must find GZ for each angle of heel. To do this, she must compute the location of B at each angle of heel, and determine the height of G above the base of the keel (the distance KG).

In the early 20th century, finding B at each angle of heel was an extremely tedious process involving a lot of trial-and-error, a lot of calculus, and days or weeks of an engineer's time. Today, this can be computerized, and takes only a few seconds once the hull is modelled in a CAD program. Finding KG, though, is still a tedious process: it can either be measured by moving weights around on an existing boat and measuring the resulting angle of heel, or it can be calculated by tallying up every piece of structure, ballast, equipment and cargo on the boat.

Once that math is done, the designer can plot GZ (or righting moment, i.e. displacement times GZ) over all possible angles of heel. This produces the familar stability curve:

All yacht skippers should be at least somewhat familiar with their own boat's stability curve, and it's a useful thing to study when buying a boat. To read the curve, we look at the following features:

  • The slope of the curve at low angles of heel tells us whether the boat is tender (shallow slope) or stiff (steep slope).
  • The righting moment at 15 to 30 degrees of heel tells us about the boat's sail-carrying power. A large righting moment indicates a boat that can fly a lot of sail; a boat with a lower righting moment will need her sails reefed down earlier.
  • The maximum righting arm (or righting moment), and the heel angle at that point, tells us where the boat will be fighting her hardest to get back upright. If this is at a low angle of heel, we have a boat with high initial stability- she'll feel very stable under normal conditions, but a bit touchy at her limits, and relies on her skipper's skill to avoid knock-downs. If the maximum righting arm occurs at a very large angle of heel, the designer chose to emphasize ultimate stability- she'll be hard to capsize, but will heel more than you might expect in normal sailing.
  • The angle of vanishing stability is the point where the boat says "Meh, I'm done" and stops trying to right herself. Looking at the diagram above, this means that Z is now at the same point as G. A larger AVS indicates a boat that's harder to capsize.
  • The region of positive stability is the region in which the boat will try to right herself. The integral of the righting moment curve (i.e. the area of the green region) is an indicator of how much energy is needed to capsize her.
  • In the region of negative stability , the boat will give up and roll on her back, her keel pointing skyward. The integral of this region (i.e. the blue area) tells us how much energy it'll take to right her from a capsize; if this area is relatively small, the waves that helped capsize her might have enough energy to bring her back upright.

Try it on a real boat

How does this apply to some real boats? Let's consider a 10 metre, 8 tonne double-ender yacht of fairly typical layout and proportions. The parent hull looks something like this:

Keeping her draught (1.5 m), displacement (8 tonnes), length (10 m), freeboard, deckhouse shape, etc. the same, we'll adjust the shape of the midship section to yield four boats that are directly comparable in all respects except beam and section shape. Hull A is a deep "plank on edge" style , hulls B and C are moderate cruising yacht shapes, and the wide, shallow-bilged hull D resembles an old sandbagger - or a modern racing sloop.

Now, assuming that G lies on the waterline (so KG = 1.5 m), we can compute the righting arm GZ as a function of the heel angle. If we multiply the righting arm GZ by the displacement, we get the righting moment.

Some immediate observations from this graph:

  • The narrow hull "A" has relatively little sail-carrying power at low angles of heel, but will self-right from any capsize. Her good "ultimate stability" comes from using ballast to get G as low as possible.
  • The wide hull "D" can fly a lot more sail, but if she goes over, she ain't coming back up. She gets her high "initial stability" from her wide beam, which moves the heeled centre of buoyancy farther to leeward.

There's a problem, though: We've assumed an identical centre of gravity for all four boats. That's not realistic. The deep, narrow hull will have her engine and tanks low in the bilge; the wide hull must mount these heavy components higher up. Let's reduce hull A's KG measurement to 1.35 m, and increase hull D's KG measurement to 1.65 m, a more realistic value. We'll scale KG for the other two accordingly.

The overall conclusions don't change much, but we now have some realistic numbers to play with.

  • Hull A, the narrow one, will have a hard time flying much sail. She'll heel way over in a breeze. But she can't get stuck upside down.
  • Hull B, a moderately slender cruising shape, also can't get stuck upside down- her AVS is 170 degrees. Her extra beam causes the centre of buoyancy to move farther to leeward when she heels, so she has more initial / form stability than hull A and can carry more sail.
  • Hull C, which is typical of modern cruising yachts, has over twice the sail-carrying power of the slender hull A. She'll heel less, and since her midship section is much larger, she'll have more space for accommodations. The penalty is an AVS of 130 degrees. That's high enough that she can't be knocked down by wind alone, but wind plus a breaking wave- such as in a broach situation - could leave the boat upside down until a sufficiently large wave comes along.
  • Hull D, the broad-beamed flyer, can hoist more than three times the sail of hull A at the same angle of heel. She'll be quite a sight on the race course with all that canvas flying. Her maximum righting moment, though, is only 37% more than hull A's, which leaves less of a margin for error- hull D is more likely to get caught with too much sail up, and will reach zero stability at a lower angle of heel. If she does go over, she has considerable negative stability, making it unlikely that she'll get back upright.

Work to capsize

If you're one of that slim percentage who paid attention in high school physics, you're probably looking at those curves and thinking: "Force (or moment) as a function of distance (or angle).... hey, if you integrate that, you get the work done !

And so you do, with the caveat that we're using a static approximation to a dynamic situation. The results are valid for comparison, but the actual numbers may not mean very much.

Let's do that for each of our hulls. We'll integrate the righting moment curve as a function of heel angle, up to the angle of vanishing stability, to get the work done to capsize the boat. We'll also integrate from the AVS to 180 degrees to get the work done to right the boat from a capsize.

Our four boats require roughly the same work to capsize! Changing the shape of the midsection affected the shape of the stability curve- a wider boat had more initial stability and less ultimate stability. In this case, though, our vessels are all about the same size and require about the same amount of work to capsize.

Righting from a capsize is another matter. The narrow, deep hulls A and B will self-right without any outside influence- a nice confidence-booster if you're heading into the open ocean, although the reduced sail-carrying power and limited interior space of these vessels will probably be more important to most skippers.

The moderate cruising hull, C, needs a bit of help to self-right, but any combination of wind and waves that can do 95 kN.m.rad of work on the boat is likely to produce a wave that can do 10 kN.m.rad of work on that same boat.

Our broad-beamed racer, hull D, is not so fortunate. Righting her from a capsize takes one-third the work that capsizing her in the first place did, and her acres of canvas were probably a major factor in the initial capsize- they're now underwater, damping her roll motion instead of catching the wind. The odds are that this boat will stay upside-down until someone comes along with a tugboat or crane.

Lessons Learned

What's the take-home message from all this?

If you're buying a new boat: Look at her stability curve, and compare it to other boats.

  • Good: Large region of positive stability, small region of negative stability, high angle of vanishing stability, steep slope at low heel angles.
  • Iffy: Shallow slope at low heel angles (makes it hard to fly lots of sail, excessive heeling when underway).
  • Risky: Low angle of vanishing stability, large region of negative stability.

If you already have a boat:

  • If you know her point of maximum stability, you can be sure to reef the sails well before  that point.
  • If you know her AVS and the shape of the curve in that region, then when a broach or knockdown happens, you already know how hard she'll fight to come back upright.
  • If you know how much area is covered by the negative stability region of the curve, you'll have some idea of whether she'll come back from a capsize on her own or else have to wait for help.
  • Determine if anything you've changed- a dinghy added on the deck, perhaps- has moved the centre of gravity.
  • If G has moved, adjust your mental model of the stability curve accordingly: just shift the curve up or down by (change in height KG) * sin(heel angle).

Confounding Factors

What we've discussed here is just about how to read the stability curve- it's not a complete picture.

There are many other factors that must be considered to get a complete understanding of a boat's stability. Among them:

  • Dynamic effects. Everything discussed so far is for the static case, and is good for comparison purposes. But in practice, boats move.
  • Waves. Stability curves are calculated for flat water, ignoring the effect of waves.
  • Differences in rigging. Weight aloft has a much larger effect on the boat than weight down low- particularly where the roll moment of inertia, an important property for dynamic stability, is concerned.
  • Keel shape. Keels tend to damp rolling motion; this behaviour is quite different with a long keel than with a fin keel, or with a fin keel underway versus a fin keel at rest.
  • Downflooding. Everything we've discussed here assumes that the boat is watertight in any position. If she takes on water when rolled, everything changes.
  • Cockpits. Our demonstration boat doesn't have a cockpit. A large cockpit could hold several tonnes of water- and with a free surface, no less. That means that G will move all over the place, usually in the wrong direction.

Further Reading

Steve Dashew's article " Evaluating Stability and Capsize Risks For Yachts ", and others on his site, discuss stability-related risks as they relate to cruising yachts.

Technically-minded readers should refer to a naval architecture textbook, of which my present favourite is Larsson & Eliasson "Principles of Yacht Design" (McGraw-Hill).

Don't even think about buying a cruising yacht without first reading John Harries' extensive series of articles on boat and gear selection .

Great stuff.

A really great piece, thank you. You have the very unusual gift of being able to make complex issues easy to understand.

Other confounding factors

One major confounding factor which most English-speaking designers still seem to routinely dismiss, or overlook, is to do with the nature of knockdown lever moments in a 'survival storm' situation:

You specifically state you're not taking waves into account, so this is addressed at those who do, in the conventional way -- generally led by the insights of academics and researchers tracing their conceptual methodology back to the likes of Marchaj.

The lever moments I'm thinking of arise from the vertical offset between: Where the wave force vector acts, and Where the hull resistance vector is located.

It has long been contended by the school of expedition yacht designers, going back to around the days of Damien II, from France in the 70s, that the greatest risk ... and arguably the only one worth worrying about for such vessels ... was due to the tripping moment caused by the vertical offset between the centre of effort of a true breaking wave, and the centre of resistance of the hull AND UNDERWATER APPENDAGES

When a large ocean wave breaks entirely forwards, the part which was formerly the crest avalanches down the front of the wave. Admittedly this behaviour is VERY rare offshore - where almost all 'breakers' actually spill most of the water down the back, but it's these events which present a real survival threat, and which define the limits to a vessel's capability.

Unlike the water particles in the body of the wave, which are circulating in the well known way of text book diagrams, and effectively not going anywhere over time, this "former crest" water has escaped from the wave system and is travelling rapidly under the influence of gravity down a steep ramp whose geometry (as opposed to constituent particles), in the case of a Southern Ocean wave of truly heroic proportions, might itself be advancing as fast as 30 to 40 knots.

So we have an aerated but still rather massive entity tumbling down above this already very fast moving ramp, hitting the topsides and cabin coamings, in the worst case, perpendicularly.

The contention of the French school was that, in this situation, while a high freeboard is clearly undesirable, the absolute last thing you want, which trumps everything else, is deep appendages providing lots of lateral grip, situated down in green water. This would provide a lever arm converting the sideways impulse (which is at a height not very far from the centre of mass, and hence not inherently an insuperable problem) into a very dangerous overturning moment.

The insight was based on simple empirical observations, such as of a flat wooden plank, or a surfboard with no appendages, floating side on to breaking waves at a surf beach. Despite having no ballast whatsoever, and a zero GZ in the plank case, this will sideslip down those waves and stay happily the same way up, in conditions where (say) a windsurf board with a deep centreboard (whether ballasted or not) will be tumbled repeatedly.

They reasoned that the thing to avoid at all costs, for a well found expedition yacht, was a knockdown with an angular acceleration sufficient to snap the rig.

This turned everything on its head with regard to the conventions of stability calculations: the relative positions of the centre of mass and the centre of buoyancy become largely irrelevant: the former should if anything ideally be high, so the vector from the striking crest passes through or near it, (to minimise the inertial overturning moment) while the latter is almost irrelevant because on the face of such a steep wave, the hull is in virtual freefall, and the hull is largely disengaged from green water. Aerated water offers little buoyancy.

This is so divorced from statics (which are arguably most useful for calculating how to prevent ships capsizing at a dock) that it is a shame to see so much reliance on static measures persisting to this day, in educating sailors, defining ultimate seaworthiness, and framing regulations and recommendations.

Be that as it may: this insight led to a completely different school of storm management by the adventurous people who sailed off to places like the subAntarctic and Antarctic in the new generation of beamy, generally low-freeboard # hulls, equipped with swing (or even dagger) ballasted keels capable of retracting - in many cases - right within the canoe body.

# ideally, no cabin trunk - which on the face of it is bad for self-righting...

In survival conditions, these sailors began retracting these keels, even though on the face of static stability calcs, this is entirely wrong. And (AFAIK*) not one of these yachts has yet been lost in the deep south, despite them making up the majority of the fleet, and I'm not even aware of a single 180deg knockdown to such a vessel configured in this way.

There have been, and continue to be, numerous knockdowns and dismastings of fixed-keel yachts designed to the other, older paradigm.

*(The first two losses of private expedition yachts in Antarctic waters both occurred within the last two years, and neither was a vessel of this type)

So even if these sailors are not right, they're clearly not VERY wrong.

Re: Other confounding factors

You are quite correct that when you are facing breaking waves, static stability analysis is not going to show the whole picture. Being caught in large breakers is certainly one of the highest-risk situations a yacht can face.

The "let it slide sideways" approach can have considerable merit in such a situation, if the boat is designed with this in mind. On a monohull sailing vessel, this calls for a retractable keel and a canoe body with relatively little lateral resistance of its own. If you do this, of course, you also have to ensure that the vessel won't trip over the leeward gunwale when she's surfing sideways with the keel retracted. There are plenty of good, seaworthy vessels out there with such a configuration.

The price you pay for doing it that way is that it's harder to right the boat if she does capsize. Frankly, though, I would rather not capsize in a non-self-righting boat than be upside-down in one that will eventually get herself back up. There are tens of thousands of catamaran sailors out there who would seem to agree.

This is not to say that static stability traits are not important: they certainly are. Given two vessels of generally similar configuration, the stability curves will tell you quite a lot about what kind of behaviour can be expected from each.

Static stability curves are certainly not the whole picture. There are several important dynamic aspects- the lateral resistance effects and the roll moment of inertia, among other features- that can have a huge effect in extreme situations. I'll discuss these in more detail in future posts.

I am thinking about. Buying a

I am thinking about. Buying a 38 foot guimond lobster boat. I am thinking Of widening the stern to 10 feet from 8 ft 8 in. Also I want to add some fiberglass to the keel to make her a little deeper maybe 36 in from present 32 inches. Should I make the new hull water line 90 degrees? Will this be better than a round traditional edge? Should I add bilge keel fins for more stability?

Modifying a design

The kind of modifications you're describing are fairly extensive. You would be wise to arrange a meeting with a naval architect, or with a builder who has extensive experience with that type of boat. With the boat's drawings and a good description of what performance characteristics you want, the professional will be able to assess what modifications (if any) would be appropriate- or if you'd be better off choosing a different design from the start.

Stabilty of Twin Keel Monohulls (Bilge Keel)

Wondering about the stability of bilge keeled sailboats, specifically the Snapdragon 26. How does a second keel affect relative stability of this kind of vessel? Any thoughts appreciated.

Static stability is determined by the hull shape and by the distribution of mass, i.e. the centre of gravity. Two identical hulls, one with a single fin and one with twin keels, will have approximately the same stability curve if they have the same centre of gravity. The twin keel configuration is usually chosen to allow shallower draught, though, so the centre of gravity will often be higher than for a single-fin boat.

There is a significant performance sacrifice with this configuration. A higher centre of gravity reduces the sail-carrying ability, the lower aspect ratio foils are not as efficient to windward, and the extra wetted surface increases drag. The flip side is that you can safely dry out at low tide in places where most monohulls would never be able to go.

Ultimately, though, the keel configuration is a fundamental part of a design, and there's no real answer to "How does a second keel affect stability". It's the performance of the entire boat that matters, and unless you have two boats that are identical except for keel configuration, it doesn't make much sense to separate out this one aspect of the design. The class's performance record and the experiences of skippers who have sailed that class in bad weather are better ways to assess the relative seaworthiness of an existing design.

Stability Curves for Hunter 34

I'm french and it's not that easy for me to understand all of this but here is my question:

Do you know who I can contact to know the stability curves of my sailboat. It's a Hunter Sloop 34' 1985

I asked directly at Marlow-Hunter, they said they don't have this information.

Someone told me that Hunter Manufacturer has it and that I can have it for some dollars but it seems that this is not the case.

Can you help me?

Tracking down data for old boats

Danielle, if I'm not mistaken, that Hunter would be one of Cortland Steck's designs. There's a chance that he might have the data you're looking for.

Stability curves are incredibly tedious to calculate without a computer, though, so many- if not most- boats designed prior to the advent of modern 3D CAD never had one calculated at all. It's possible to build a computer model of an existing boat and calculate the required data, but for most practical purposes you can find the important information through an inclining experiment. This essentially consists of moving known weights around the boat and measuring how she heels in various load conditions, and it's one of the more common ways of measuring stability data for an existing vessel in commercial service where all of these details must, by law, be properly measured and documented.

Righting a Capsized Vanguard Nomad 17

I read on the web that it takes 420 lbs of crew weight to right a capsized Nomad. Is that true? I weigh 135 lbs and I sail single-handed. It's now November and the water is getting too cold to find out.

Re: Righting a Capsized Vanguard Nomad 17

Gerardo, A 625 pound boat with a beam of 8 feet is not going to be an easy thing to right. You might find Sailing World's article on the boat interesting. They were advised by the manufacturer's rep that the boat can't be righted by one person in the way that you'd right something small like a Laser. But if you flood the tank (through the spinnaker well) on one side, you'll be able to roll her far enough to pull her back up like a dinghy, and then drain the tank again. I agree that you would NOT want to test this in November!

37 Foot Sailboat

I am from the Maldives in the Indian Ocean. I am building a fiberglass sailing yacht using local boat builders. Its 37 feet and 11 feet with a long keel of 3 foot deep. And will use concrete in the keel. They will be putting 9 fiberglass mats. Interior and the bulkheads will be done using marine plywood. The hull is going to look more like a Fisher 37. And the cabins like a Nauticat. I am intending to use ketch style two masts. I was surfing the internet and am trying to understand what are the issues that I need to take into consideration. Your explanations is very helpful. I am just wondering whether you will comfortable if I communicate on this topic. Thanking you.

Re: 37 Foot Sailboat

Ahmed, it's good to have you here and feel free to chime in on relevant threads, or to contact me directly. It's always neat to see what everyone else is building.

Help with stability estimate

Matt, I found your article very informative, good stuff! Where might you think my vessel Crusoe might fit A thru D.
 57' O.L. 13' beam-25 tons-4.5 ton ballast lifting keel. Here is the vessel:
 
 http://yachthub.com/list/yachts-for-sale/used/sail-monohulls/pilothouse-... 
 thanks,
 
 Thomas

To summarize, in very general terms: Category A is an offshore-capable yacht. Category B is a coastal cruising vessel, able to handle weather at sea but not recommended for extended offshore use. Category C is a short-range inshore vessel that is expected to take shelter rather than facing a storm out in the open. Category D is a small, fair-weather vessel such as a skiff or dinghy. The static stability properties are the main factor that determine which category a particular boat design is intended to fall in. But, in addition, the builder must comply with dozens of requirements for structural integrity, watertightness, emergency equipment, etc. for the boat to actually fall in that category. It's quite possible for a boat designed for Category A to end up being a Category B vessel because of corner-cutting during the build.

Assessing Southerlies and Tayanas

Would you care to give an opinion on the Southerly Yachts with retractible keels and twin rudders, also on Tayanas as to seaworthiness and construction. Thank you

Southerly & Tayana

I don't have first-hand experience with either of these marques, so I'm afraid I can't offer much that's meaningful.

Southerly tends to have a fairly good reputation. You do pay a fairly substantial premium for the complicated retracting keel, but there are some cruising grounds where the only options are a retractable keel or a multihull.

The Tayana line has produced a mix of models from several different designers, some very traditional, rugged and slow, others relatively modern. I'd have to know exactly which one you have in mind to say much more than that.

Your best bet for meaningful data on either line would be to prowl some forums looking for the owner's club for each marque. Yacht owners generally love to talk about their yachts, and if you're patient, you can usually find most or all of a particular model's weak spots by asking owners how they handle rough weather and what they've had to fix or replace so far.

I really enjoyed your article

I really enjoyed your article. I'm trying to make a stability model myself and I was interesting in the equations you used to find GZ as a function of heel angle and then how you found the displacement. I'm also interested in how you calculated the different curves for the different hull designs. Any pointers would be greatly appreciated. Thanks!

I'm not sure if I mentioned

I'm not sure if I mentioned it in my last comment, but I'd also like the equations for getting the displacement you multiplied GZ by. Thanks!

Sources for calculations

Hi Cole, Finding the displacement from the lines is pretty easy. If it's a CAD model, just find the volume; if it's a 2D drawing, find the area of each of the stations and use Simpson's rule to integrate over the waterline length. Finding G is just a matter of adding up the weights and moments for every component of the ship - each frame, the hull planking, the engine, each piece of hardware, and so on. Finding GZ for a given heel angle is relatively tedious, but it's essentially the same procedure (find the station areas, integrate over the waterline length, find the station centroids, weight the centroid offsets by station area to find the CB). There is an iterative step here as you must adjust the waterline position to make the displacement the same as in the at-rest case. For practical purposes, though, virtually everyone computes their stability curves using a proven software tool like Orca3D or ArchimedesMB. The actual calculations are described in detail in most good yacht design textbooks, eg. Larsson & Eliasson's "Principles of Yacht Design".

Stability of Chinese Junk Hull

Hi Matt, Your article is very informative. I am studying the feasibility of building a wooden ocean going Chinese Junk. History recorded that there were huge junks sailing 600 years ago in Zhenghe's days. The latest record for a large junk sailing across oceans is the Keying which sailed from Hong Kong to New York and London in 1848. She is 160ft LOA, 33ft BEAM and 13ft (rudder up) 23ft (rudder down) DRAFT, 700-800 ton DISPLACEMENT. As it is too difficult to re-build a wooden junk of such size, I am studying the record of fishing junks built about 30 years ago. A junk capable of sailing in force 8 wind. She is 23m(75.4ft)LOA, 5.66m BEAM, 1.69m(DRAFT), 1.2m(FREEBOARD), 138000kg (DISPLACEMENT). There is a dagger board extending 2.5m from the bottom, located about 1/3 waterline from the bow in front of the main mast. The rudder can be raised in shallow water. It is perforated with an area of 6.7sq.meter. The bottom is almost flat. The design of junks were evolved from generations of experience without scientific verification. I am surprised that the length and beam is so close to Volvo 65, but the displacement is 10 times those of Volvo. I am wondering if a flat bottomed boat is stable in rough ocean condition until I read the comment by Andrew Troup in 2012 about a boat without appendages can surf safely on the steep slope of the waves. I am glad if you can shine some light on the stability of traditional Chinese junks. John Kwong

Chinese Junk

A hundred and thirty-eight tonnes on 23m LOA? Yowzah, that's quite the boat. There's nothing fundamentally wrong with a relatively flat bottomed shape, or with retractable appendages. The risk of a flat bottom is more to do with slamming and pounding, which is much less of a problem in a heavy boat. Before investing hundreds of thousands of dollars in such a boat today, it would certainly be prudent to have the design drawn up and analyzed with modern software tools. There are certainly improvements from the last 50 years that could be applied to a much older design. A six-century pedigree is nothing to sneer at, though, and the fundamental design - updated with some modern construction techniques and with the added confidence of a full stability analysis - might still be a good one.

Relative locations of G and B

Hi Matthew. Thanks for such an interesting and informative article. Most diagrams show B below G so I guess this must be the most usual arrangement. However, I wondered if there might be a class of yacht (lightweight but with deep bulb keel) where G moved below B. I guess this would give a very good static G-Z curve (but I note also the comments made by Andrew (above) re dynamic stability that this might not be the best design to go winter sailing in the Southern Ocean!)

Monocat Hull

Matt what would you think this Monocat 50 Hull Form (see link)? Its a very different design- Monohull at the Bow, Catamaran at the Stern, 2x Lift Keels, One Ballasted, the other Forward non ballasted dagger board. I just cannot find information on it anywhere? I'd assume it would have similar characteristics to a very beamy monohull and thus would not self-right from a knockdown!? This is what im wanting to find out, will it self-right & is it safe offshore? Mashford Monocat 50 15.24m LOA 5m Beam 3Ton Ballested Lift Keel 0.8m - 2.1m

(there is a cad drawing of its underwater hull design in this advert) NB: Unfortunately your Spam Filter will not let me paste the link, but if you search the internet for MASHFORD MONOCAT it comes up for sale everywhere.

Ive been trying to locate the Designer Chris Mashford with no luck? feel free to email me too any info, cheers. Mal

Mashford Monocat

I'm not too familiar with the Monocat. My educated guess would be that stability-wise, it'll be much like a "skimming dish" racer - very stiff and powerful at first, hairy at the edge, and not self-righting. I'd have to sail one to be sure, but I have a suspicion that it could have the worst of both worlds - the relatively high drag and the ballast burden of a mono, with the complexity and high sailing loads of a cat. The main appeal seems to be the huge living space in a relatively modest beam, suggesting it's meant for short-term coastal cruises and charter work. Reliable reports on them seem to be very hard to come by, I suspect they weren't built in large numbers.

Great article! Thanks. My question is on actual statistics of vessels that have actually capsized. Understanding that this would likely be under reported, it would seem fruitful ground to examine questions of which static or dynamic factors pan out and are predictive for hulls that ended up upside down, and the stories behind them?

Does such a database exist?

reason for knowing the departure gm

Sorry I am bringing in a different topic entirely . pls I have read most of your articles and I have found them to be very useful . Pls I really want to know the importance of knowing your departure gm before commencing on a voyage... thank you

downflooding

Hi Matthew - I was reading your blog just now on Aug 23. I wanted to know how intake of 450l water affected the stability of a 9000kg / 41ft sailing yacht that I was skippering in a force 9 storm around Dover on Aug 3rd 2017. We encountered rather high waves of estimated 7m and had 52 kts apparent wind, which may have been the beginning of a force 10, because we did only 4kts through the water under storm jib and 3x reefed main. Once safely parked in Dover, we pumped 450l water out of the boat. Floorboards were floating... Any idea how that amount of water may have affected stability?

Kind regards

Martin Lossie

Calculating a stability curve

You mentioned calculating stability curves is tedious, and mostly done with CAD these days. I'm a new owner of a 1969 Columbia 26 Mk II and would love to understand the stability curve for my boat. A few enterprising owners have rescued the blueprints of this boat and placed them online, so I have the measurements available. Are there folks out there willing to do the CAD work to create the curve? Otherwise, what would be the easiest way for me to get one created for my boat?

Thanks for a GREAT article explaining this concept!

  • Self righting boats

Some vessels with a centre plate are considered self-righting with no crew on board, with the centre plate down, and the mast at no more than 90 degrees.

Experience shows self-righting boats can and do get ‘knocked down’ or capsize, increasing the risk of inversion and entrapment. There are known examples where through a variety of factors they have subsequently inverted, including with the keel or weighted centre board retracted. There are known examples where a sailor has slipped out of a knocked down boat, increasing the risk of entrapment and reducing the ability to right the boat. If you are faced with such a situation, the important thing is knowing what to do and how to do it.

Mitigations, such as mast head floats, may increase the time a boat is on its side rather than inverted.

Manufacturers will use owner manuals and guides to share information about a vessel’s limitations (e.g. rigging, safety features, conditions, number of people, load).

Some sailors may have restricted mobility or ability to help themselves if they ended up in the water or partially in the water. Equipment is available to maintain posture or improve control of steering / sails that has the effect of securing the sailor to the vessel. Both of these factors can increase the risk of entrapment.

Boats with a ballasted lifting keel are heavy and while the standard techniques to right them work, they may require more power.

The self-righting characteristics of any boat are compromised if a lifting keel or weighted centreboard are not in the down position, as is the ability to right from an inverted position.

Actively trimming sails, rather than cleating them off enables them to be released quickly if needed.

Implications for practice and procedures

  • Users of any vessel should familiarise themselves with its stability and righting characteristics.
  • Use vessels within the limits and safety features described by the manufacturers.
  • Any mechanism for securing the plate or keel in the down position should be checked to ensure it is operating as intended and all sailors and volunteers should be briefed on the importance of its use.
  • Brief volunteers, instructors and participants about the value of actively trimming sails rather than cleating them off.
  • If a sailor is limited in their ability to help themselves if they ended up in the water or where they are secured to the vessel in any way, it is worth considering additional mitigations:
  • mast head buoyancy
  • reducing sail area
  • the level of safety cover to ensure supervision in the immediate vicinity.
  • when the conditions may limit operation (see manufacturers recommendations).
  • Procedures and drills for recovering a 'self-righting' boat should include scenarios where a) the boat has inverted with the keel in the lowered position and b) where the keel or centreboard has retracted from its ‘lowered’ position,
  • When choosing engine size and vessel type for safety boats, consider the types of vessels you may be recovering,
  • The preference is to right a knocked down or inverted boat in reverse, with the engine away from anyone who may be in the water. However, if low engine power may cause concern and potentially restrict the ability to recover the craft, you could consider using a longer tow rope and recover by driving forwards.

Any modifications that deviate from the original design may alter the stability of a vessel and limit access to the full range of controls. Find out more.

  • An approach to safety

An overview of the key elements of safety systems

Providers of activity have a clear duty of care to keep those involved in the activity safe. People of all ages, with a wide range of impairments go sailing. It is important to consider the person, the situation and the staff / volunteers involved before making safety decisions.

  • Personal flotation

It is important to get the choice of personal flotation device right each time a person goes afloat, particularly for people who may not be able to actively participate in their own self-righting if they were to end up in the water.

  • Strapping and harnesses

Strapping and other equipment are used for several reasons including to maintain posture and improve control of sails and steering. Straps and harnesses can be used by a person day to day (for example, in a wheelchair) or as a specific part of sailing equipment.

Self-righting means different things for different vessels. Experience shows self-righting boats can and do get ‘knocked down’ or capsize, increasing the risk of inversion and entrapment. There are known examples where through a variety of factors they have subsequently inverted, including with the keel or weighted centre board retracted.

  • Adaptations to boats

Any modifications that deviate from the original design specification may alter the stability characteristics of that vessel and access to the full range of controls (steering and sails).

  • Recovering boats

When towing vessels participants usually remain in the boat. The seating arrangements in some vessels used for disabled people, and participants’ own limited mobility, may make it harder for the crew to stay out of the way of a tow rope, particularly if multiple vessels are being towed

  • Recovering people

Explore equipment like slings or wet nets, the importance for having a plan for individuals who may not be able to fully help themselves and the role really good communication plays

  • Seating and posture

Seating and posture are important for both personal safety and the ability to take an active part in sailing.

Boat Profile

Ptarmigan 17

A Selway Fisher pocket cruiser

From Issue   December 2021

Y ears ago, I had built and sailed a 14′ flat-bottomed skiff, but the time had come for something with more capacity, capability, and comfort. A few times my wife Ramona and I had been caught in rough conditions that made me feel more than a bit uncomfortable, and I didn’t feel confident heading out to distant shores with the little boat. And sleeping under a tented boom, well, I’d had enough of that. Still, it was nice to have a boat I could tow home and store in the garage where I could keep it in good repair.

Selway Fisher’s Ptarmigan 17, as drawn, met most of my needs and could be adapted to suit the rest. The options detailed in the plans took care of my wants, and the design appears to accommodate amateur builders with a range of skills and requirements. There are drawings for both stitch-and-tape and glued-plywood lapstrake construction. You can also choose between a simple catboat rig and a yawl rig. With all the options for customization, I wouldn’t be surprised to see 10 different boats built from the same set of Ptarmigan 17 plans.

best self righting sailboat

The glued-plywood lapstrake construction accentuates the hull’s curves. Stitch-and-tape construction without the laps is an option included in the plans.

The boat’s optional yawl rig had piqued my interest. I liked the idea of sailing under a balanced helm if the conditions got too serious, and I thought that the smaller mainmast on the yawl rig would be a bit lighter to lift. The combination tabernacle-equipped mainmast, small cabin, and ease of trailering led me to finally choose this design.

The building package comes with seven sheets of construction plans and a 14-page booklet of instructions. Dimensions are metric. A concise building schedule outlines each step of the build with recommendations on the choice of plywood, instructions on using epoxy, and what fastenings to use. There’s a section on how to lay out and draw the side panels on the plywood, and how to draw curved elements using a grid pattern. Measured drawings for the molds, stitch-and-tape side panels, bottom panel, and stem are clear and easy to follow. You do not need to do any lofting to build this boat. There are detailed drawings and instructions on stitching and filleting. The plans are complete with details for building sub-components such as rudder, centerboard and trunk, and the tabernacle. The plans are cross-referenced with the instruction booklet and provide the recommended scantlings.

There are instructions for building an outboard well or a transom cutout. All specifications for the standing and running rigging are listed. For builders interested in making their own sails, there’s even a reference to a Selway publication on that topic. The booklet is light on details for the four-strake, glued-lap plywood version; however, there are several good books available on the topic.

Both of the Ptarmigan 17’s sail rigs are gaff-rigged. The single-mast catboat rig carries a sail area of 139 sq ft and includes the dimensions for an optional 24-sq-ft jib. The yawl rig’s total sail area is a little smaller at 135 sq ft, with a main of 79 sq ft, a jib of 36 sq ft, and a leg-o’-mutton mizzen of 20 sq ft. There are two reefpoints drawn on the mainsails. With the yawl rig you can douse the mainsail in high winds and sail with a balanced helm under jib and mizzen. The yawl—with bowsprit and boomkin —is almost 23′ in sparred length. The mizzen is self-tending and only requires attention when coming off the wind. The plans do not specifically address tackle, but we made our own blocks in keeping with the overall look and feel of the boat. There are several good articles on making your own blocks in various publications.

I found the plans for this boat detailed, complete, and accurate, and while a few questions did arise, they were quickly answered via email. When I started this build, I found many ways of keeping safe and saving time; the project took me five months of full-time effort.

T he boat tows well behind an SUV or pickup truck, and the trailer does not require brakes for the boat’s 1,300 lbs. The flat bottom and shallow 6″ keel help keep the weight low in the boat. For trailering, I keep the bowsprit attached and secure the mast in a cross-framed 2×4 support; the gaff, boom, and mizzen are supported and strapped to the frame and the forward ends pass through the companionway.

The yawl rig has an 18.9 sq ft mizzen, a 78.8 sq ft main, and a 36.6 sq ft headsail.

With some practice, the yawl can be rigged and ready to go in about 20–25 minutes. It saves time to tag the rigging to help remember where the stays go and in what order they go on. The mast is lifted with its three stays, three halyards, and the topping lift set in place. The foot of the mast is secured in the tabernacle. Lifting the rigged mast requires some effort but is manageable and made easier with the help of someone pulling on the headstay. I secure the jaws of both the gaff and the boom using 1/8″ braided nylon cord with several parrel beads threaded on. I lace on the sails, add the rudder and motor, take off the securing straps, and I’m set to launch. When hauling out at the ramp, I have a 2,000-lb single-speed hand-operated winch that handles the boat with ease. The boat always seems to attract a crowd filled with compliments, comments, and questions.

The plans call for open slats for the cockpit seating and sole. The builder’s modification to plywood enclosures provides convenient storage.

The 5′x 6′ cockpit will accommodate four but is most comfortable with one or two. With two, there’s plenty of room to hoist the sails and move around when coming about. The helmsman has a clear view forward of the small jib over the cabin. The mainsail is high enough off the cabin roof to have a clear view to port and starboard. All sheets and halyards are led aft into the cockpit and can be easily handled without the need for winches. The throat and peak halyards need a hefty tug. The plans call for 7mm (3/8″) halyards, which I find easy on the hands. The 65″ x 25″ footwell is 17″ deep. The trunk is 4″ wide and its cap is 12″ above the cockpit sole. It extends into the footwell 20″ and passes through the main bulkhead to within a foot of the forepeak bulkhead. The steel centerboard is raised and lowered with the help of a worm-gear winch that is operated from the cockpit. With the board down, the boat draws 3-1/2′.

best self righting sailboat

The cabin has bunks for two. The centerboard trunk divides the footwell between them.

The cabin interior is 6-1/2′ x 5-1/2′ and is 52″ high at the crown. There are two bunks that run the length of the cabin and are 26″ at their widest. For sitting there is good headroom and ample legroom in the footwell between the bunks. Storage compartments are built into the underside of each bunk. It’s a simple interior, but it keeps you dry. The yawl cabin has a support post under the tabernacle that is about 16″ abaft the forepeak bulkhead. The tabernacle in the catboat version is supported by the forepeak bulkhead. The plans call for a sliding plywood hatch over the companionway, but I chose to make mine with a plexiglass top for added light in the cabin. There are two 12″ x 16″ windows on the cabin sides. If you wish to build a self-righting boat, the instruction booklet calls for adding buoyancy under the cockpit benches and forward of the forepeak bulkhead. An additional 160 lbs of lead can be bolted to the floor as extra ballast.

The boat’s 1,300-lb weight gives the feeling of stability—it is not tippy when you step aboard—and will carry through when tacking in light air. The Ptarmigan 17 was designed for inland lakes, estuaries, and coastal areas, and I have never felt uncomfortable in these waters. Adding one or two larger sails both on the jib and mizzen would be nice to have for sailing downwind and in lighter wind conditions. In windy conditions, the first reef goes in when the winds approach 20 knots. Anything above this and the main is doused and tied off. Even in these conditions the boat has never left me feeling unsafe; it feels stable and there is no need to put the rail in the water. The ride is generally dry, with little spray. Passengers in the cockpit can sit close behind the cabin to shelter from the elements. The rudder is shallow and extends 3’ beyond the transom. It controls the boat well in all conditions.

While the builder ultimately chose to use an outboard bracket, his Ptarmigan 17 has a built-in motorwell appropriate for a small outboard. The opening of the well is visible at the bottom of the transom.

The plans and notes describe an optional motorwell, set to starboard, but do not specify the size of the auxiliary outboard motor. A 2.5-hp is all Ramona and I need to get into and out of the harbor, or back home when the wind dies. I built the motorwell to house an electric trolling motor but found that I needed more power, so I switched to a small gas motor that I set on a transom-mounted bracket. The motorwell could easily accommodate the 2.5-hp outboard.

W hen I decided to build this boat there wasn’t a lot of information on how the boat would perform. A few pictures and a description by the designer were all that I had. My experience with a smaller boat helped refine my requirements for the new boat, which the Ptarmigan 17 met: capable of crossing the larger lakes in almost any condition, easily towed behind our pickup, and equipped with a dry bed to crawl into at night. I did make some modifications, such as building a self-draining footwell and building fiberglass-covered benches to drain the rainwater over the side. To provide more storage space, I extended the forward ends of the side benches, covering the centerboard trunk with more seating. Now I can leave the boat unattended at a mooring without having to worry about the cockpit filling with water.

If you’re looking for a small cruising sailboat to explore far and wide, that you can easily trailer and store at home in between adventures, then you should take a close look at the Ptarmigan 17. Just be ready for the many admirers you’ll meet along the way.

Steve Cormack is a self-taught amateur builder with a workshop in Pender Harbour, British Columbia. He started building boats nearly 40 years ago and has completed several small plywood kayaks and strip canoes. In addition to the Ptarmigan, he has built a Handy Billy motorboat (which he uses for day trips), and a Selway Fisher Blackswan 22 for cruising. He is currently finishing a 32′ Lake Union–style dreamboat based on a Katherine 30, designed by William Hand Jr.

Wow! Amazing! Do these plans include the modifications of the self draining foot wells and benches and storage space? Or are those changes a builder would have to figure out on their own?

Stacey, I modified the design according to a few of my own preferences. One was for a self-bailing cockpit floor and the other was for seats that would shed the rain water. These adaptations are well suited to our climate here on the west coast of Canada.

Hello Steve, You have built a very charming pocket cruiser. You obviously have some accomplished woodworking skills. Are the protruding frames above the deck and the strong bulwark attached to them a modification to original design plans? A lovely and practical feature. How is the deck sealed around frames to ensure waterproofing? Is there room for a portable loo and small galley flat in the cabin? Any frustrating weather helm issues with the yawl rig? Lawrence

Thanks, Lawrence. Yes, I did extend the frames to allow for the small bulwarks. I used epoxy putty to fill any voids then covered the deck with a 6-oz glass cloth set in epoxy. I have not had any issues with leaks as of yet.

I suppose you could fit a small portable loo if designed in during construction; same for the galley. I might suggest a galley that could be set up when needed and stowed especially at night when you need the space for the berth.

I don’t recall any issues with weather helm as of yet, and am more than happy to have the option of dousing the main altogether should the conditions require it.

I watched your video of your Black Swan project and of your Ptarmigan 17 build. I am certain Paul Fisher must be very pleased and honoured by your handiwork. Congratulations! Lawrence

Do you suppose the cat rig could be replaced by a junk rig fairly easily, with the sacrifice of a through-cabin mast?

10 Best Small Sailboats (Under 20 Feet)

Best Small Sailboats Under 20 Feet | Life of Sailing

Last Updated by

Daniel Wade

December 28, 2023

Compact, easy to trailer, simple to rig, easy to maintain and manage, and affordable, the best small boats all have one thing in common: they offer loads of fun while out there on the water.

So whether you're on a budget or just looking for something that can offer ultimate daytime rides without compromising on safety, aesthetic sensibilities, alternate propulsion, and speed, the best small sailboats under 20 feet should be the only way to go.

Let's be brutally honest here; not everyone needs a 30-foot sailboat to go sailing. They come with lots of features such as electronics, entertainment, refrigeration, bunks, a galley, and even a head. But do you really need all these features to go sailing? We don't think so.

All you need to go sailing is a hull, a mast, rudder, and, of course, a sail. And whether you refer to them as daysailers, trailerable sailboats , a weekender sailboat, or pocket cruisers, there's no better way to enjoy the thrills of coastal sailing than on small sailboats.

There are a wide range of small boats measuring less than 20 feet available in the market. These are hot products in the market given that they offer immense thrills out on the sea without the commitment required to cruise on a 30-footer. A small sailboat will not only give you the feel of every breeze but will also give you the chance to instantly sense every change in trim.

In this article, we'll highlight 10 best small sailboats under 20 feet . Most models in this list are time-tested, easy to rig, simple to sail, extremely fun, and perfect either for solo sailing or for sailing with friends and family. So if you've been looking for a list of some of the best small sailboats , you've come to the right place.

So without further ado, let's roll on.

Table of contents

{{boat-info="/boats/hunter-15"}}

The Marlow-Hunter 15 is not only easy to own since it's one of the most affordable small sailboats but also lots of fun to sail. This is a safe and versatile sailboat for everyone. Whether you're sailing with your family or as a greenhorn, you'll love the Hunter 15 thanks to its raised boom, high freeboard, and sturdy FRP construction.

With high sides, a comfortable wide beam, a contoured self-bailing cockpit, and fiberglass construction, the Hunter 15 is certainly designed with the novice sailor in mind. This is why you can do a lot with this boat without falling out, breaking it, or capsizing. Its contoured self-baiting cockpit will enable you to find a fast exit while its wide beam will keep it steady and stable no matter what jibes or weight shifts happen along the way.

This is a small sailboat that can hold up to four people. It's designed to give you a confident feeling and peace of mind even when sailing with kids. It's easy to trailer, easy to rig, and easy to launch. With a price tag of about $10k, the Hunter 15 is a fun, affordable, and versatile boat that is perfect for both seasoned sailors and novices. It's a low-maintenance sailboat that can be great for teaching kids a thing or two about sailing.

Catalina 16.5

{{boat-info="/boats/catalina-16-5"}}

Catalina Yachts are synonymous with bigger boats but they have some great and smaller boats too such as Catalina 16.5. This is one of the best small sailboats that are ideal for family outings given that it has a big and roomy cockpit, as well as a large storage locker. Designed with a hand-laminated fiberglass sloop, the Catalina 16.5 is versatile and is available in two designs: the centerboard model and the keel model.

The centerboard model is designed with a powerful sailplane that remains balanced as a result of the fiberglass centerboard, the stable hull form, and the rudder. It also comes with a tiller extension, adjustable hiking straps, and adjustable overhaul. It's important to note that these are standard equipment in the two models.

As far as the keel model is concerned, this is designed with a high aspect keel as the cast lead and is attached with stainless steel keel bolts, which makes this model perfect for mooring or docking whenever it's not in use. In essence, the centerboard model is perfect if you'll store it in a trailer while the keel model can remain at the dock.

All in all, the Catalina 16.5 is one of the best small sailboats that you can get your hands on for as low as $10,000. This is certainly a great example of exactly what a daysailer should be.

{{boat-info="/boats/hobie-16"}}

There's no list of small, trailerable, and fun sailboats that can be complete without the inclusion of the classic Hobie 16. This is a durable design that has been around and diligently graced various waters across the globe since its debut way back in 1969 in Southern California. In addition to being durable, the Hobie 16 is trailerable, great for speed, weighs only 320 pounds, great for four people, and more importantly, offers absolute fun.

With a remarkable figure of over 100,000 launched since its debut, it's easy to see that the Hobie 16 is highly popular. Part of this popularity comes from its asymmetric fiberglass-and-foam sandwiched hulls that include kick-up rudders. This is a great feature that allows it to sail up to the beach.

For about $12,000, the Hobie 16 will provide you with endless fun throughout the summer. It's equipped with a spinnaker, trailer, and douse kit. This is a high-speed sailboat that has a large trampoline to offer lots of space not just for your feet but also to hand off the double trapezes.

Montgomery 17

{{boat-info="/boats/montgomery-17"}}

Popularly known as the M-17, The Montgomery 17 was designed by Lyle C. Hess in conjunction with Jerry Montgomery in Ontario, California for Montgomery Boats. Designed either with keel or centerboard models, the M-17 is more stable than most boats of her size. This boat is small enough to be trailered but also capable of doing moderate offshore passages.

This small sailboat is designed with a masthead and toe rail that can fit most foresails. It also has enough space for two thanks to its cuddly cabin, which offers a sitting headroom, a portable toilet, a pair of bunks, a DC power, and optional shore, and a proper amount of storage. That's not all; you can easily raise the deck-stepped mast using a four-part tackle.

In terms of performance, the M-17 is one of the giant-killers out there. This is a small sailboat that will excel in the extremes and make its way past larger boats such as the Catalina 22. It glides along beautifully and is a dog in light air, though it won't sail against a 25-knot wind, which can be frustrating. Other than that, the Montgomery 17 is a great small sailboat that can be yours for about $14,000.

Norseboat 17.5

{{boat-info="/boats/norseboat-17-5"}}

As a versatile daysailer, Norseboat 17.5 follows a simple concept of seaworthiness and high-performance. This small sailboat perfectly combines both contemporary construction and traditional aesthetics. Imagine a sailboat that calls itself the "Swiss Army Knife of Boats!" Well, this is a boat that can sail and row equally well.

Whether you're stepping down from a larger cruiser or stepping up from a sea kayak, the unique Norseboat 17.5 is balanced, attractive, and salty. It has curvaceous wishbone gaff, it is saucy, and has a stubby bow-sprit that makes it attractive to the eyes. In addition to her beauty, the Norseboat 17.5 offers an energy-pinching challenge, is self-sufficient, and offers more than what you're used to.

This is a small, lightweight, low-maintenance sailboat that offers a ticket to both sailing and rowing adventures all at the same time. At about 400 pounds, it's very portable and highly convenient. Its mainsails may look small but you'll be surprised at how the boat is responsive to it. With a $12,500 price tag, this is a good small sailboat that offers you the versatility to either row or sail.

{{boat-info="/boats/sage-marine-sage-17"}}

If you've been looking for a pocket cruiser that inspires confidence, especially in shoal water, look no further than the Sage 17. Designed by Jerry Montgomery in 2009, the Sage 17 is stable and should heel to 10 degrees while stiffening up. And because you want to feel secure while sailing, stability is an integral feature of the Sage 17.

This is a sailboat that will remain solid and stable no matter which part of the boat you stand on. Its cabin roof and the balsa-cored carbon-fiber deck are so strong that the mast doesn't require any form of compression post. The self-draining cockpit is long enough and capable of sleeping at 6 feet 6 inches.

The Sage 17 may be expensive at $25k but is a true sea warrior that's worth look at. This is a boat that will not only serve you right but will also turn heads at the marina.    

{{boat-info="/boats/laserperformance-laser-sb3"}}

Having been chosen as the overall boat of the year for 2008 by the Sailing World Magazine, the Laser SB3 is one of the coolest boats you'll ever encounter. When sailing upwind, this boat will lock into the groove while its absolute simplicity is legendary. In terms of downwind sailing, having this boat will be a dream come true while it remains incredibly stable even at extraordinary speed.

Since its debut in 2004, the Laser SB3 has surged in terms of popularity thanks to the fact that it's designed to put all the controls at your fingertips. In addition to a lightweight mast, its T- bulb keel can be hauled and launched painlessly. For about $18,000, the Laser SB3 ushers you into the world of sports sailing and what it feels to own and use a sports boat.

{{boat-info="/boats/fareast-18"}}

As a manufacturer, Fareast is a Chinese boat manufacturer that has been around for less than two decades. But even with that, the Fareast 18 remains a very capable cruiser-racer that will take your sailing to the next level. In addition to its good looks, this boat comes with a retractable keel with ballast bulb, a powerful rig, and an enclosed cabin.

Its narrow design with a closed stern may be rare in sailboats of this size, but that's not a problem for the Fareast 18. This design not only emphasizes speed but also makes it a lot easier to maintain this boat. Perfect for about 6 people, this boat punches above its weight. It's, however, designed to be rigged and launched by one person.

This is a relatively affordable boat. It's agile, safe, well-thought-out, well built, and very sporty.

{{boat-info="/boats/chuck-paine-paine-14"}}

If you're in the market looking for a small sailboat that offers contemporary performance with classic beauty, the Paine 14 should be your ideal option. Named after its famous designer, Chuck Paine, this boat is intentionally designed after the classic Herreshoff 12.5 both in terms of dimensions and features.

This is a lightweight design that brings forth modern fin keel and spade rudder, which makes it agile, stable, and faster. The Paine 14 is built using cold-molded wood or west epoxy. It has varnished gunnels and transoms to give it an old-time charm. To make it somehow modern, this boat is designed with a carbon mast and a modern way to attach sails so that it's ready to sail in minutes.

You can rest easy knowing that the Paine 14 will not only serve you well but will turn heads while out there.

{{boat-info="/boats/wd-schock-lido-14"}}

Many sailors will attest that their first sailing outing was in a Lido 14. This is a classic sailboat that has been around for over four decades and still proves to be a perfect match to modern small boats, especially for those still learning the ropes of sailing.

With seating for six people, the Lido 14 can be perfect for solo sailing , single-handed sailing, or if you're planning for shorthanded sailing. While new Lido 14 boats are no longer available, go for a functional used Lido 14 and you'll never regret this decision. It will serve you well and your kids will probably fall in love with sailing if Lido 14 becomes their main vessel during weekends or long summer holidays.

Bottom Line

There you have it; these are some of the best small sailboats you can go for. While there are endless small sailboats in the market, the above-described sailboat will serve you right and make you enjoy the wind.

Choose the perfect sailboat, invest in it, and go out there and have some good fun!

How To Sail A Sailboat By Yourself | A Complete 9 Step Guide

best self righting sailboat

Until this point, you’ve always sailed with others onboard, but this time, you’re thinking of going solo. You’ve watched enough experts and have some firsthand experience, so you think you’ll fare well. Still, there are a few knowledge gaps you wish to fill in before you embark on your journey. How do you sail alone?

To sail a sailboat by yourself, make sure you follow these steps:

  • Learn everything about your boat 
  • Practice everything on tranquil seas
  • Take a safety class
  • Know some basic knots
  • Don’t sail without jacklines 
  • Have a capsizing preparedness plan
  • Let someone know where you’re going and for how long 
  • Master anchoring 
  • Never leave without a life vest or life raft 

In this comprehensive guide, we will cover all the above steps in much more detail, explaining everything you need to do to set sail solo. By the time you’re done reading, you’ll feel confident enough in your skills to safely navigate the waters by sailboat alone.

Sailing a Sailboat by Yourself: Steps to Follow

1. know your boat inside and out.

When you sailed in the past, more than likely, you divided your responsibilities among you and the other sailors onboard. For that reason, you’re very familiar with some parts of a sailboat, but maybe not all of them. Some sailors may even know all the sailboats components but never used a lot of them.

That won’t do when you’re riding solo. You now do everything there is on the sailboat. You’re the engineer, the bow-person, the navigator, the dial trimmer, and the skipper. You need to not only become comfortable with every last square inch of your sailboat, but you need to know every last secret your boat holds. When you close your eyes, you should envision the layout of your sailboat in your head. 

This may sound excessive, but it’s completely necessary. If you’re fortunate, you’ll have calm conditions on your voyage, but that’s not always realistic. You need to know how to handle your sailboat in emergencies, and that means memorizing every last part of it. This knowledge will take you far and help you feel more comfortable and confident in the idea of sailing by yourself. 

2. Practice, Practice, Practice

You know the old saying that practice makes perfect, right? It’s true. When planning your solo expedition, you want to give yourself lots of leeway. If you can space the trip out a few weeks or even months ahead of time, that will give you ample time to practice. 

After all, you can read about boating terms until you go cross-eyed, but nothing can beat first-hand experience. This is where your familiarization of your sailboat will come from. You want to spend as much time on the water as you can. It’s best to practice in the calmest conditions possible. 

Yes, as we said, the weather probably won’t be perfect every day of your voyage. However, you don’t need the added pressure of a storm when you’re trying to hoist your sails for the first time. It’s going to make it nearly impossible for you to get the job done sufficiently. 

Instead, what you can do is simulate emergency situations. For instance, time yourself on certain tasks, such as trimming, sail hoisting, mainsail reefing, and more. If you’re getting these jobs done quickly enough, then you’ll know that should you have to do them fast, like in a storm, you’ll be fine. You can do that without a single gray cloud in the sky. It’s like having a safety net, which is nice for first-time solo sailors. 

3. Enroll in a Sailing Safety Course 

In your time preparing for sailing your sailboat by yourself, you have probably learned a lot. You might think you know all there is about sailing, but trust us when we say you can always learn more. Sometimes you don’t even realize there are topics you glossed over until you get on your boat and you have no idea where to find the spinnaker pole.

To augment your knowledge and maybe even teach you a new thing or two, we recommend you take a sailing safety course. At the very least, you’ll be all caught up on the latest safety rules and regulations. Plus, like we said, there’s the opportunity to learn, and that’s always good, too. Even if the course acts like a refresher for you, you’ll have all that info in the front of your mind when you set sail.

If you’re doing any kind of offshore racing or cruising, then we suggest taking the Safety at Sea Seminars through the Cruising Club of America specifically. Here, you’ll glean lots of great safety info for offshore racing on your sailboat. 

4. Familiarize Yourself with Tying Knots

There are three general types of sailing knots. Do you know them all? Hitches can attach your line to the stanchion, piling, or cleat. Knots that connect more than one line, like a sheet bend, go by the name bends. Then your stopper knot or your bowline knot would be categorized under basic knots.

Besides those classifications, you must also learn how to tie a handful of sailing knots if you’re going to commandeer your sailboat alone. While maybe you don’t have to know all of the following by heart, get comfortable with them anyway:

  • Cleat hitch: A cleat hitch attaches your dock lines to your cleat. To make a cleat hitch yourself, take your rope and rotate it around the cleat’s base once. The line should be led until its length extends beyond the cleat. Move the line to the cleat’s first horn, making a figure eight there. Then repeat on the other horn. Tuck the line in and secure it by pulling it.
  • Rolling hitch: If your winch drums lines get jammed up, then you’ll rely on a rolling hitch. You want to begin by taking your line and securing it around a post or fixed line. Now do this again. For the third go-around, take your original line’s standing end and put the working end atop it. Go back to the secondary line, tying the original line’s working end over the turns of the secondary line. Give the standing line a tug.
  • Two half hitches: The two half hitches knot can secure many items aboard your sailboat, so learn how to do it. You can start by wrapping your line around the item in question. Attach the first hitch to the turns by taking its working end and tugging it through is standing end. Do the same thing with your second hitch. 
  • Sheet bend: Instead of square knots, try a sheet bend instead. They’re more stable, so they won’t untie under pressure. Tie your own sheet bend by making two half hitches as explained above. You want to then create a running nose between the two half hitches. 
  • Clove hitch: It should take you mere seconds to tie a clove hitch once you become familiar with it. When you want to connect your toerail, stanchion base, or lifeline to your fender whips, a clove hitch comes especially in handy. To start, take your line and wrap it once fully around the item. The line should overlap itself by the second turn. Leave no spare line, so make sure the working line is part of the knot. Give the whole thing a tug to secure it.
  • Stopper knot: Last but not least, we recommend you know the stopper knot. This will keep your line where you want it, unable to slip through your rope clutch or block. Start at the back of the line with a stopper knot. With your working knot, pull it around your hand, keeping it open as you do so. Wrap it around a second time and then push the line’s working end beneath. Release the knot from your hand, holding onto the working end and pulling so the knot will tighten. 

5. Get Your Jacklines Set up and Always Have Them Ready

In case you don’t know (although we hope you do), your sailboat’s jackline connects from your stern to the bow via wire or rope. You can attach a safety harness to the jackline so you can get across the sailboat’s deck in an emergency, such as when capsizing (more on this in a moment). 

Jacklines serve an incredibly crucial purpose, then. While it’s great to know how to tie some of the above sailor’s knots, you want to make sure that your jackline is in place above all else. Besides emergencies, they also come in handy once night falls, in fog, and during storms. 

Now, you’ll have to rig the jackline yourself, starting it at your sailboat’s bow to its stern. Make sure you do this on both the port side and the starboard. You should have your jacklines set up even if you’re not expecting bad weather. This way, should a storm roll in, you don’t have to waste valuable time stringing the jackline. It’ll be ready to go. 

6. Learn How to Come Back from Capsizing

As we’ve written about on this blog before (see here ) capsizing is something that can and likely will happen to your sailboat at some point or another. If you recall from that blog post, when sailboats heel or turn at an angle, they’re at a higher risk of capsizing. Also, the lightweight design and shape of a sailboat doesn’t do it any favors when it comes to staying upright.

You shouldn’t think of capsizing or tipping over as a “what if” scenario, then. In fact, depending on the conditions you ride in and how long you plan on sailing, you could end up capsized more than once. Unfortunately, capsizing can lead to death, so it’s very important you’re not caught off-guard. 

You need some sort of plan of attack for what to do when your sailboat capsizes. Whether you get a self-righting boat from the get-go or you learn to right your sailboat when it tips, you need to be ready. 

7. Never Sail Without Someone Knowing about It 

Woo-hoo! You’re about to set sail for your first solo trip and you couldn’t be more excited. You’ve already put in a lot of legwork, studying up on all the terms and parts of your boat, passing a sailboat safety course, practicing your sailing, and tying lots of sailor’s knots. Now you’re ready to ride the open seas on your sailboat. You feel more than prepared.

Wait, hold on. Before you embark, did you let anyone else know of your plans? We don’t just mean vaguely, but detailed information of your trip? If not, then you need to change that ASAP. This sailing communication plan can save your life. It’s ideal if the person you choose is someone with a modicum of sailing knowledge (or even some moderate knowledge), but even if they’re not as experienced as you, it’s still good to have someone aware of your plans.

You want to tell this person where you’re going, how long it should take you to get there, the day and time you’re leaving, and the day and time you estimate you’ll arrive. If that date and time passes and there’s still no sign of you, this contact of yours could try reaching out. 

You have a few means of staying in touch, even on your sailboat. Your smartphone works, but you will have to keep it charged. Also, sometimes, connectivity can be spotty since you can sail pretty far from any cell towers. You could always get a satellite phone or sailboat Wi-Fi installed on your vessel, although neither come very cheap.

8. Know How to Anchor Your Sailboat

If you’re sailing or cruising on a multi-day trip, then you’ve got to stop and sleep sometime. When you do, you’ll have to anchor your sailboat so you don’t lose control of it during your respite. Otherwise, you could end up lost. Your boat could also hit other vessels, crash into a shoreline, or plummet against some rocks, all of which would end your trip very fast. 

Where you choose to anchor matters. You want to make sure you’re not close to a lee shore, since sometimes even when you anchor your sailboat, it will drag a little. The place you select should also offer adequate safeguarding from both waves and wind. If you can stick your anchor in mud or sand, that’s best. It can slip off grass, seaweed, and rocks. You should drop your anchor to a depth of 30 feet, sometimes even 40 feet, but you must make sure you have the right amount of anchor rode, between 200 and 300 feet of the stuff. 

When you do finally drop your anchor, you don’t want to rush it. Stop your sailboat completely and then let the anchor go. If you do this too fast, the anchor might not settle where you want it, which is just as bad as not having anchored your sailboat in the first place. 

9. Have a Life Vest or Life Raft Onboard

As we’ve said already, when you’re sailing by yourself, you assume all duties onboard the vessel. There’s no one else looking out for your safety but yourself, so you must take your own safety very seriously. In all the hustle and bustle of preparing for your first solo sailing trip, you could forget some things. 

While that does happen, one item you must absolutely not forget is a life vest or life raft. You might even bring both since you only need one of each. If it’s a life vest you prefer, then you want to get it fitted before you set sail. The vest should fit close to your body but not to the point where it’s constricting. If you can’t maneuver freely, then the vest is too tight. If it slips right off you when you try to do anything, then it’s too loose. 

We’re not asking you to wear your life vest 24/7, but you can if you want to. You do always want to know where it is and have it within arm’s reach. If you need to put it on very quickly, it won’t be too far away. Having a life vest can be the difference between life and death in a sailboat incident, so please, never forego yours.  

Related Questions

Will a sailboat right itself.

Sailboats won’t right themselves unless you get a model that’s self-righting. These boats can flip themselves back upright without any intervention on your part. If you’re in the market for a new sailboat, then it’s recommended you get a self-righting model. That’s doubly true if you plan on sailing alone. It can be very difficult to push a sailboat upright if you’re by yourself.

Will a sinking boat pull you under?

If your sailboat begins to sink and you’re still onboard, you may wonder what the risk is of it pulling you under with it. It can happen if the sailboat gets full of water and you don’t move or swim to safety. By staying with the boat, a rip current-like situation can develop, where the force of the water pulls you down, potentially causing drowning.

How to Right a Capsized Sailboat

How to Right a Capsized Sailboat

Capsize is the term used when a Sailboat is tilted at a 90º angle or turned over in the water. It has something to do with the movement of the crew weight or excess weight concentrated on the wrong side of the boat. It can also be due to too much power in the Sail.

In this section, learn how to avoid capsizing or deal with a small capsized sailing Dinghy :

How to Avoid Capsizing

  • Familiarize yourself. Keep in mind that Capsizing is very common when sailing a small boat. This fact can make you prepared. Know the different situations where Capsizing becomes inevitable. Getting familiar with the causes can help you in avoiding them as you go afloat. It is wise to know the things you need to do if the boat capsizes. In protected waters with good conditions, practice dealing with a capsized boat. Get familiar with the steps to do to make the boat upright again. Make sure that you wear a Life Jacket. It will be better if you have someone on another boat to give assistance when necessary.
  • Know your limitations. Sail within the limits of your skills and ability to respond to situations. Knowing how to make the boat upright when sailing a Dinghy or small boat is very crucial. If you do not know how to deal with a capsized boat, sail on a more stable one. Small Keelboats and other types of Dinghies are more stable and less likely to capsize. For obvious reasons, do not go afloat if the conditions are not favorable for Dinghy Sailing.
  • Know how to reef a Dinghy. A Dinghy becomes easier to handle in strong Winds if it is reefed. Reefing, or reducing the Sail Area, is an important skill to learn. Knowing how to properly adjust the Sail area of a Dinghy while on the water can help you in keeping it upright.
  • When Sailing Downwind Place crew weight astern and keep the boom down.
  • When Sailing Upwind Place crew weight to windward. Slightly raise the Centerboard or Daggerboard to decrease the Heeling effect. Take control of the speed of the boat. It is more likely to capsize if it heels and slows down.

Knowing the causes of Capsizing will help you in avoiding it. In the event that your boat capsizes, do not get embarrassed. Having a capsized boat is not something to be ashamed of. Many sailors have their own share of experiences in getting their Dinghy capsized. The important thing is that you learn from the experience.

Methods of Righting a Capsized Boat

Dealing with a Capsized boat generally depends on the size of the Sailboat and on what circumstances you are sailing in. Wind and wave conditions at that particular time should be taken into consideration.

Here are some Techniques in Righting a Capsized Boat:

  • Release the mainsheet and tiller and climb towards the opposite side.
  • Climb over the top gunwale (top edge of the side of the Hull). Step over the sidedeck to reach the Daggerboard.
  • Stand on the part of the Daggerboard nearest to the Hull and hold the gunwale.
  • Pull the boat upright. Climb back to the boat as soon as it is upright again.
  • Scoop Method The heavier person rights the boat by standing on the part of the Centerboard nearest to the Hull to pull the boat upright. The other person is scooped aboard. His weight will prevent the boat from another Capsizing once it is upright. In this method, release the mainsheet and jib sheets in order for the Mainsail to wave loosely when the boat is upright again.
  • Walkover Method As the boat capsizes, you and your crew member should climb over the opposite side of the boat to reach the Centerboard. Climb back into the boat as soon as it is righted.
  • Traditional Method Turn the boat in such a way that the Mast is downwind or the bow is pointed into the Wind. The first person should stand on the Centerboard, while the second crew member keeps the boat into the Wind. From the Stern, the first person boards the boat and helps the other crew member onboard.
  • Righting an Inverted Boat The buoyancy distributed on the bottom and sides of the Hull makes a lot of Dinghies more at risk to turtle (turn completely upside down). In this situation, the Centerboard will likely to slip back into its case. When this happens, stand on the opposite gunwale and pull on a jib sheet or fixed righting line and lean out. Bring the boat to its horizontal or capsized position. Do the suitable Righting Technique to make the boat upright.

In recovering a Capsized boat, ensure that you and your crew (if you are sailing with another person) are safe at all times. Wear a Life Jacket afloat and remember to stay with or near the boat when it capsizes.

How to Right a Capsized Sailboat – Conclusion

Do not be embarrassed if your boat capsizes. In general, getting wet because your boat capsized is both a learning and fun experience. This is actually a good way to teach you several important skills in boat handling and techniques on how to deal with different situations.

Self-righting

  • Add to quote

Hello, I''m new to sailing so apologies if this is a dumb question. Is there an easy way to tell if a boat is self righting in a capsize by looking at figures like ballast, displacement etc? At the moment I am learning in (on?) toppers these capsize easily ( well, they do when I sail them ) and do not self right - but that is part of the fun. Single handing bigger boats, say 16 to 22 ft, this could be a problem. Thank you for any info. Paul  

I think most manufacturers can tell you if their boat is self-righting. I grew up sailing a San Juan 21 and the manufacturer said it was self-righting. After sailing the boat for years, I had a sudden squall hit me once while I was beating into the wind. The boat went over, the sails hit the water, and in a fraction of a second, the boat popped right up. After experiencing this, I always felt alot safer sailing the boat in heavy winds. I think for most people this should be a rare event. It happened only once in my 20+ years sailing the boat. The time it happened, my single crew member was inexperienced, and he didn''t let the jib sheet go quickly enough. Good Luck. Rob ~~~~_/)~~~~

Self righting is a comparative term. All boats have a point at which they are stabile upside down. In most keel boats that point comes between 120 and 140 degrees of heel. In unballasted boats that typically occurs somewhere around 80 to 90 degrees of heel. The statically calculated angle of "ultimate stability" or "negative stability" for a production boat is a pretty inexact number as it is affected by the way the boat is equipped and loaded. Because the calculation needs to include factors related to hull and cabin shape as well as weight distribution it is also a pretty elaborate calculation. There are a variety ''surogate'' formulas that try to apporximate the ultimate stability of a particular design but because they ignore the two most critical factors in determing stability, namely the locations the center of gravity of the boat and the location of the boats center of bouyance over a wide range of heel angles they are terribly misleading. These formulas primarily focus on secondary factors affecting a boat''s ultimate stability as Follows: Beam- Wide beam contributes to a boat''s stability when it is standing up straight but as the boat heels beam becomes a liability to the boats ultimate stability. Weight- Weight adds to a boat''s inertia (a heavier boat feels more stabile when you step aboard from the dock) but weight really does nothing for stability in an of itself. If that weight is carried high, (in teak decks, heavy hull, hull rig and interior furnishings) as it often is in heavy cruising boats, it can actually result in pretty poor ultimate stability. Surogate stability formulas use weight a major determinant but without the vertical center of gravity being taken into account that info is useless. Draft- All other things being equal, the deeper the center of gravity the greater the ultimate stability. Deeper fin keel boats, with their lower center of gravities often will generate greater stability than their heavier bretheren. So back to your question. Generally keel boats are advertized as being self-righting and unballasted centerboarders are not. You will sometimes see surogate stability numbers published. Bigger race boats that have been certified under the IMS racing rule have a calculated ultimate stability on their rating certificate that is a reasonably close to correct number. Otherwise assume that to a point a ballasted boat will be self rescuing and an unballasted boat will not. (One more aside- boats with water ballast and other low density ballast materials tend to not have great reserve stability.) Does that Help? Good luck Jeff

Will a Sailboat Right Itself? (Explained for Beginners)

Categories Sailing

Regardless if it is your hundred times sailing at sea, you might have a pinch in your heart whenever big waves try to capsize your sailboat. 

There is a real chance that your sailboat might tip over to fight against big rocking waves but will your sailboat try to upright itself in that situation. Well, here we are to dissect every part of whether the sailboat will right itself or not through this article.

Will a sailboat right itself?

The boat’s stability depends on some factors like gravity, the center of buoyancy, angle of heel, etc. The sailboat will eventually right itself immediately when the boat’s arc doesn’t cross the angle of heel because that is the last point from where the sailboat will be able to right itself.

Table of Contents

best self righting sailboat

Sailboats can right themselves automatically because the manufacturers construct these boats by following some physics rules.

Also, to prove your boat’s stability power, the manufacturers will provide you a graph for your new sailboat that plots all the righting points against the angle of heel.

Modern yachts, ships, or sailboats can be more stable than the narrower boats because they can reduce the angle of vanishing stability more quickly, which makes them stable if it is in a fully inverted position.

Can a capsized sailboat right itself?

A capsized sailboat will right itself automatically , but it depends on some factors, and the factors are discussed down below:

The boat’s stability depends on the primary factor: creating rotational forces by two forces that are center of gravity and center of buoyancy.

The center of gravity always works down the boat, and the center of buoyancy works up the ship.

When the boat leans over one side from the other due to waves or centrifugal force, the center of buoyancy changes from the center of gravity; at that moment, the creation of rotational force due to the evolution of angle from the two forces makes the boat return to its upright position. 

This is the main reason why your sailboat will not tip over so quickly, but there are some exceptional cases where boats could not be able to right themselves.

This may be because of a manufacturing fault, or maybe the boat’s angle has crossed the angle of the heel, or the ship could not maintain a similar optimum angle of drive to the wind of sails.

Thus, your boat will not be capsized very quickly, but the ship will eventually upright itself to a stable position if it does.

Do sailboats capsize easily?

The sailboats don’t capsize easily , but there may be some exceptional situations where your boat might flip over. There are a lot of reasons where your boat might capsize very soon.

Firstly, you have to make sure that your boat can stabilize itself and does not cross the angle of the heel. To prove that your ship has the ability to be stable properly, the manufacturers will provide you a graph that plots the righting moment against the Angle of Vanishing Stability.

Secondly, the weight of your crew can cause your boat to lose its balance because the crew sits on one side of the ship, there is a big chance that the boat will flip over to that side.

That is why a small board can be steered without a rudder on another side to shift the crew’s weight on that side to stabilize the boat.

Thirdly, speeding can put your boat at risk of flipping over because you can hit a rocking wave while you are speeding, which will make your boat tip over.

On the contrary, taking sharp turns can also force your boat to capsize because taking sharp turns at high speed will roll your boat. Always keep in mind that the rules of physics are the same everywhere, whether you are driving on water or road.

Finally, rough weather can make your sailboat capsize, too, as the bad weather brings strong winds, which usually is the main reason for forming huge and rocking waves.

Also, there is a massive risk that the strong winds will blow off your sail, and we know that sail is very important for keeping your sailboat stable. Strong winds can make your boat rollover if you are climbing big waves one by one.

Therefore, it is really crucial to keep the above points in your account if you don’t want your boat to capsize.

How to right a capsized sailboat?

There are necessary measures you can follow to right a capsized sailboat. But before taking any of the steps, you should make sure that the people in your sailboat are in a safe condition.

Most importantly, you will need to determine the boat’s position to be sure that it is not sinking. If the ship is not sinking, then there is a high chance that the boat will right itself, but if it isn’t, then swim away from the boat as far as possible.

However, you can also try the scoop method, where you can scoop one of your heavier crews in the cockpit as the other will try to upright a capsized boat. The weight of the person will help the vessel to upright the position of the boat.

You also can try the walkover method where you and your crew will climb over the centerboard of your boat on the opposite side and then climb back into the boat as soon it gets right.

You can also follow the traditional method where you have to keep the Mast downwind and the bow to the way of wind and then turn the boat.

The first person will stand at the centerboard, and the other crew will keep the boat to the point of wind. While from the Stern, the first person will board the boat and help the other crews to board on the boat.

In the case of an inverted boat, you can try to stand on the opposite upper edge and try to pull out the jib sheet or try to fix the righting line and then move out. Then try to move the boat to its capsized position and then apply the correct righting method to make the boat stable.

How do you keep a sailboat from capsizing?

There are few techniques you can follow to keep a sailboat from capsizing, but among them, the essential method is to maintain weight displacement on the sailboat.

You always have to make sure that the weight is kept in the middle rather than keeping it on one side of the boat.

It is better if you take less weight on the boat because a lot of weight can put your boat at risk of capsizing. Always remember, the lighter the boat, the less there is a chance that the boat will flip over.

You need to test your sailboat before buying so that they can make right themselves during capsizing situations.

Otherwise, you can check the manufacturer’s manual to see if they have been tested before, and also, there are instructions on to make your sailboat right during leaning situations.

Also, make sure that you are not speeding by any means because speeding is the most common reason why the sailboats rollover. Adding to that, you should not also speed while taking turns on the corners or taking sharp turns.

Finally, if you find yourself in a capsizing boat, try to remain calm as much as possible and try to follow the above-discussed steps to make your sailboat upright.

Why do sailboats lean so much?

Sailboats which include displacement hulls, will literally flip over/lean as they turn. As it goes along, the mass of a displacement hull boat is balanced between the above and below water components.

The sailboat’s above-water pressure has an inertia or momentum effect as it turns, pulling it towards the other side of the turn. Thus the more sharply the turn is made, the more it can capsize out of it.

This ensures you’re pretty likely to get a flip out of it, even though most shipping vessels and naval ships have precautions in place and the ability to keep their cargo stable during an occurrence like this.

Why does a sailboat not tip over?

Modern sailboats don’t tip over because they have the resistance to reduce the angle of the heel, making them stable quickly from the leaning position.

Also, if you select sail correctly and also keep it in the right direction with the wind, then there is less chance that the sailboat will tip over.

Also, the keel is a hidden weapon under the deck that obstructs the boat from being pulled out across the water sideways. While the keel’s force is balanced with the sail’s force, the sideways pressures are canceled out, and the boat moves towards without capsizing.

What does a keel do on a boat?

The keel is the structural building member and foundation of the vessel, extending around the centreline of the lower surface on which the ship’s hull is constructed. It is the ship’s central portion, to which all other critical mechanical parts are related, both wholly or partly.

Why do boats need ballast?

Modern sailboats use the ballasts or weight on the ship’s hull to keep the boat from tipping over in rough water or rocking waves. The ballast keel also helps to maintain the balance of the boat from capsizing due to strong wind.

How far can a sailboat heel?

Well, It depends on the boat’s heel ability, but one thing’s for sure any kind of sailboat has the ability to heel about 20 degrees. But it is suggested from the experts that the boat should not heel too much that it crosses the angle of the heel, and the boat gets flipped over.

Although the wind direction can play the bitter role to heel your boat to that point where it crosses the angle of positive stability, you need to have better knowledge about the correct technique of righting your sailboat.

Best Self-Righting Pilot Boat – Willfreedom – Safehaven Marine

best self righting sailboat

Through the impressive performance and safety record of its pilot and patrol boats, Ireland’s Safehaven Marine has achieved a global record for excellence. This has helped it achieve a remarkable record of vessel sales.

This a very impressive pilot boat and a typical example of Safehaven’s outstanding quality.

best self righting sailboat

“The boat is special as she has the capability to operate as a conventional pilot vessel but also as a crewboat,” Safehaven told Baird Maritime . “As such, she is capable of carrying up to 12 persons all seated comfortably on shock-mitigation seating.”

The company said that, having built over 35 examples of boats from the same series, no significant difficulties were encountered. However, it was still useful to understand the specific customer  requirements for such dual roles in a single vessel.

When asked to comment on the future of the pilotage industry, Safehaven said durability and safety will become increasingly important attributes in new vessels.

“We predict that the industry will continue to require our type of proven all-weather-capable heavy duty pilot craft with an increasing emphasis on pilot safety and vessel efficiency.”

Traxxas RTR Spartan SR (Self Righting) Boat [VIDEO]

Traxxas RTR Spartan SR (Self Righting) Boat [VIDEO]

From Traxxas : XTREME FULL-THROTTLE FUN WITH SELF-RIGHTING SECURITY

Spartan SR is built for speed and performance. Pull the trigger and Spartan SR immediately jumps on plane and rips across the water to its heart-pounding 50+ mph top speed! There’s nothing else like it and nothing holding you back. If a wave pitches the wrong direction, self righting is on board and within seconds, Spartan SR is back to extreme, full-throttle fun.

SELF-RIGHTING SECURITY

Self righting is more than a convenience feature, it’s an all-access pass to exploit Spartan’s full 50+ mph fury. Boaters of all skill levels will enjoy the confidence-inspiring security of self righting. There’s no need to back off the throttle or tone down the action. Just pin the throttle and Spartan SR takes care of the rest.

RAZOR-SHARP HANDLING

Spartan SR’s deep-V ABS hull carefully balances speed with agility for a truly thrilling driving experience. A new electronics layout and battery tray drastically improve handling precision by concentrating the weight inboard along the centerline. The result is razor-sharp handling, no-lift turns, and superior high-speed stability.

50+ MPH SPEED

Grab a fistful of throttle and Spartan SR’s VXL-6s™ Marine power system transforms 22+ volts of LiPo power into furious acceleration. The high-performance prop digs in, getting the boat on plane quickly and efficiently as it slices through the water at speeds of 50 mph and beyond.

SELF-RIGHTING FLOOD CHAMBER

If Spartan SR flips over, the flood chamber immediately begins filling with water until the boat rights itself. A molded foam insert in the bow provides excess buoyancy. Once Spartan has righted itself, hit the throttle to drive away and the water in the flood chamber instantly exits the rear of the boat. The entire process takes only seconds and Spartan is back in the action.

HIGH PERFORMANCE PROP

Spartan’s prop gets the hull on plane quickly to reach maximum speed with the least current draw. Traxxas engineers tested countless prop configurations to find the perfect balance of performance, efficiency, and durability. Molded composite construction makes the prop light and tough, with no balancing or sharpening required.

  8. How Does A Self-Righting Boat Work? Life-Changing Approach!

    Self-righting boat means a boat that can roll back to upright condition by itself even after mighty external forces like wind and wave cause the vessel upside down. The vanishing stability of a self-righting boat is almost 180 degrees. The vanishing stability is an angle up to which a vessel shows a positive self-righting moment.

  9. Understanding monohull sailboat stability curves

    A larger AVS indicates a boat that's harder to capsize. The region of positive stability is the region in which the boat will try to right herself. The integral of the righting moment curve (i.e. the area of the green region) is an indicator of how much energy is needed to capsize her.

    Self righting boats. Self-righting means different things for different vessels. An all-weather lifeboat can recover from a full 180-degree inversion.

  12. How do lifeboats self-right?

    What self-righting looks like. The weight (W) is the force of the boat pushing the water down through the centre of gravity (G). The buoyancy (B) is the force of the water pushing up through the centre - and this doesn't change, even when moving in waves. A boat floats upright when these forces are balanced. As the boat begins to capsize ...
