WHAT IS IT?

The UFO is a simplistic modern hydrofoiling boat, that allows anyone to fly through the air, freeing the hull from draggy water. More stable than the International Moth -or even a child’s pram- with a simple rig, and a set of fully retractable hydrofoils, all for $11,500 USD the UFO makes flying attainable. Thousands less than it’s nearest competition. Built in the United States in high volume and quality control, the UFO maintains a one-design philosophy, creating close and exciting racing on foils!

FUN FOR ALL AGES

The wand system controlling the foils, which can be set to fly very high, very low (even ‘no fly mode’) and all points in between. This means you can progressively add challenges to your UFO experience as you feel ready for them, from ‘beginner mode’ all the way to ‘extreme mode’. Additionally, the highly tunable sail can be set up to provide only the amount of power that your body type needs, and no excess. This means that the UFO is accessible and fun for sailors of all sizes, ages and skill levels. Merely set up the boat for your skill level and body type and go play around.

The UFO is very broadly applicable and has flown payloads from 70 pounds -a tiny kid- to 270 pounds -a tall grown man and a teenage boy-. The foil package just needs power to climb. Ultra light sailors have been caught on camera flying in 5 knots of breeze and the baseline for 225 pound sailors to take off is 10 knots. 270 flies in 12 knots of breeze.

SETUP AND BREAKDOWN

While the boat can be left on shore with everything in place, but the sail down, that doesn’t mean the UFO isn’t easy to put together or take apart. Quite the opposite. Simplicity begets simplicity and the boat is a cinch to put together and take apart.

MANAGEABILITY

Being small is it’s own reward when it comes to handling the boat through all sailing experiences. When you start to really push yourself learning to foil, there are good odds you’ll manage to capsize it. The UFO is easy to right from capsizes and even full “turtle” inversions. This last part is critical, because when catamarans are too heavy to right from turtle the only option is to make the mast float. This has the unintended downside of making the boat very likely to blow away from you. The UFO is designed to stay right alongside you in the event you are separated from the boat. Additionally, the boat possesses an uncommon “park” mode in which it will hold station of its own accord, apparently indefinitely without external input of any kind. The full benefits of that upside have not begun to be fully exploited.

FOILING AT ALL POINT OF SAIL

The Fulcrum design team strictly adhered to the axion “if there’s a point of sail (say, upwind or downwind) that it can’t always foil on, you can’t call it a foiler”. The design team achieved their goal and the UFO is a fully flying boat on all points of sail, which drastically increases its fun-factor.

At what points of sail does the UFO foil at?

The UFO fully foils at all points of sail. Upwind, downwind and reaching. Additionally, you can set it to not foil when you’re tired and it will do that as well, so you can get home easily. These two factors make the UFO uniquely good for learning to foil.

Who can fly the UFO?

Within reason, anyone.

UFO pilots have ranged from 8 years old to 72, from 90 pounds to 235. Young sailors do well sailing as pairs or with a middleweight to light adult. It’s rare that anyone on the fulcrum team conceives of a boat with a narrow niche in mind. Why bother? It’s a mistake in yacht design to design a boat for a narrow range of users, when for the most part people are diverse and the objective of one-design boats is to garner large fleets. That said, the boat is likely to be most satisfactory in all wind conditions in the hands of teens, small and medium men and all women. At the extreme low end of the weight range, sailors may find themselves overpowered and at the extreme high end, the wind speed required for takeoff is about two knots higher than average. UFOs have been sailed “two up” as well, though the above limits of weight range still apply to the sum of the two sailors weights.

What wind and waves can I fly a UFO in?

The UFO will sail in practically any wind condition. However, it’s important to remember that with all sailboats there are days that are great to sail in and days where you do something else.

While the UFO can at times with a skilled skipper take off in very low wind speeds, the baseline for reliable flight is around eight knots. Trying to squeeze enough power to fly out of too little wind is tiresome and in those circumstances, it’s best to do something else. In 8 knots and above, flying is magical and unforgettable. In under 8 knots, the UFO reverts to being a pleasant displacement catamaran and goes from being exciting and fast to relaxing and tactical. This is another benefit of being a catamaran.

Over the last six years the UFO has proven to be uniquely good at flying safely and consistently in very high windspeeds. In multi-class foiling regattas the UFO has proven to be the only foiler built to date that simply loves high windspeeds. In winds above 22 knots when other foiling boats make for shore, the UFO wants to keep playing. The upper wind limit is more a matter of taste and skill. UFOs have been sailed in 36 knots, but that requires a great deal of skill and focus. The UFO rig having shared DNA with a windsurf rig seems to play a part in the boat’s remarkable ability to get a kick out of big wind. Since the upper wind limit on the UFO is so much higher, this makes the number of optimal days to fly a UFO (if skilled in sailing one) higher per year than with any other production foiling boat.

Most chop and wave conditions present no issue for a UFO set for the days’ conditions. After all, powered hydrofoils were first developed by various leading Navy’s as a means of smoothly flying over challenging sea-states. Choking up the ride height helps the UFO fly smoothly through the bottom of the wave pattern, undeterred. Rolling seas present even less issue, as the UFO will ride along them just like any other. Extremely tight and tall chop can be very annoying, which is not peculiar to the UFO.

Waves do effect baseline windspeeds to achieve takeoff. Imagine getting a plane to take off on a bumpy runway. This is true for all hydrofoil boats. In choppy water, ten to twelve knots can be necessary to achieve fully easy takeoffs. Some UFO sailors use aggressive kinetic techniques to overcome this and take off in choppy water and low wind.

Will I fly my first time out?

Most people do, but bear in mind that flying is a whole new experience and it takes some learning.

Conditions, setup and technique matter and if you use it incorrectly, you are likely to get some degree of incorrect results. That’s the challenge that the UFO is built to address. Over six years on the market and over 500 boats delivered, the UFO has proven to be the best and most reliable platform for ordinary sailors to reliably teach themselves foiling technique on.

What happens when I crash my UFO into something?

You’ll probably do some damage to it.

The UFO is built with durability as a core objective but it’s worth noting that the gulf between “Feather light under engineered ragged-edge high performance craft” and “literally indestructible” is extremely wide. The UFO represents neither of these extremes. Do not attempt your first flight inside a densely packed mooring field. Obstacles only make you better once you’ve mastered the basics.

How easy is it to rig a UFO?

Best in class, vs other foiling boats on the market. With that said, it’s not easier than doing nothing. Doing nothing is very easy! Putting a boat together is worthwhile but obviously involves effort.

The current cartop to launched speed record is roughly 15 minutes. Socket the mast together. Attach the boom and stays in one go. Step the rig. Flip the boat on its side, insert the foils, right the boat, hoist the sail and launch. Complexity is best avoided.

Leaving the UFO on a dock or a beach with the rig in and the foils simply in the “up” position, achieves an ease of daily use on par with any light beach cat. To go foiling all you need to do is hoist the sail with the halyard, clip the sail to the boom and attach the downhaul line and you’re ready to launch. This brings setup and breakdown to a matter of five minutes or less.

How do I launch and land a UFO?

Far far far more easily than any other foiling boat on the market.

Because the UFO is a very small catamaran, while floating the hulls float relatively deep in the water and create lateral resistance, like the hulls on a hobie 16 or hobie wave. This means that it can sail upwind without a daggerboard of any kind in the water. This is not the case with non-catamaran foilers. The rudder is outfitted with a friction brake and a down-halyard to allow its depth to vary and allow steering in shallow water. So from 16 inches of water and beyond, you can sail away from and back to shore reliably.

Because the UFO’s forward foil assembly is located in front of the mast, the UFO can tack and gybe while the forward foil is fully withdrawn from the water. This is unique. It allows the UFO to navigate reliably in the period between launching or landing and flying. The benefits for usability and safety cannot be overstated.

Once you’ve got to deep enough water, lower your foils fully and fly away!

That’s if you’re using a dolly.

If you aren’t using a dolly, the UFO has even more party tricks to show off. Since the foils withdraw to above the waterline of the hull, the hull can be beached or slid up onto a dock float or boat deck without any risk to damaging the foils. The UFO is a boat that’s eager to go sailing.

Can I easily cartop a UFO?

At this hull weight, the boat is very easy to put on top of a car, and its flat bottoms allow it to be strapped down hard with no drama. The other components of the boat collapse down to the point of easily fitting in a standard hatchback.

Where can I store my UFO?

Anywhere you can carry it to. Anywhere it fits.

Behind couches, under beds, under porches, in basements, inside larger boats, chained to apartment fire escapes, hanging in garages. Anywhere it can go that’s convenient for your lifestyle is a good place for it to go.

Why does X look like Y? Surely it would be better to make it like Z.

Just trust us.

If you’ve thought of it, we’ve weighed the pros and cons and its been included or excluded for good reason. Creating a boat that can be produced at an affordable price, for a wide range of sailors with a maximum quantity of accessible performance is an extremely hard target to hit. The UFO meets all of its objectives and does so by blatantly ignoring a few conventions and norms. You simply don’t make an omelet without breaking eggs.

Boat of the Year 2020 F101: Best Foiler

By Dave Reed
Updated: December 10, 2019

At A Glance

Price As Sailed: $24,750

Design Purpose: Learn to foil, advance skills

Crew List: One or two

Rob Andrews and his business partner Alan Hillman have been teaching foiling for a few years now, and one thing they’ve learned is we get better by sailing, not by swimming. Thus was the genesis of the F101, a craft with which they could teach the fundamentals of foiling—without the crash and burn. But it’s not just a learn-to-foil boat, either. It’s a platform with which new and experienced converts alike can take their foiling skill set to a higher level.

The key to mastering the F101, Andrews explains, is grasping righting moment. With the trimaran platform, you get plenty of it, as well as a stable boat that’s more forgiving than any other small foiler. “The trimaran configuration gives you righting moment direct from the foil in the middle hull,” he says, “and gives a measure of safety. It’s hard to capsize the boat.”

The judges learn as much when it comes time to sail the F101. In 15 knots and more, and a steep Chesapeake chop, Powlison is first to give it a go. He settles into the boat, gets his bearings, perches skittishly on the weather hull, sheets on the mainsail (no need to use the boat’s gennaker above 12 knots) and off he goes like a bat out of hell, popping up on the foils without even trying.

“The trick is getting used to the sensation of heeling to windward,” he says. “It takes a bit of trust. Once foiling, it’s quiet and fast, and I felt like I had to be really active on the mainsheet to keep it on the foils.”

That’s true of any foiler, but the beauty of the F101, the judges agree, is when you do lose it, it’s no big deal. The boat drops off its foils, the bows auger in and you get a face full of water; but just reset, bear away and try again.

“The hull shape picks up the buoyancy gently,” Stewart says, “which makes it depress smoothly and prevents it from pitchpoling. When I dumped it a few times I thought I was going in, but not a chance. You quickly realize there’s plenty of floatation there to save you. In flat water, with one day of training you’d get up to speed quickly.”

When teaching people to foil, Hillman starts with “skimming,” a ride height barely above the surface. As the sailor becomes more accustomed to how the boat behaves, there’s a simple line adjustment at the foil head: Dial it up one setting and increase your ride height.

As you’re sailing, the foil wand hanging behind the trailing edge effectively feels where the boat is riding relative to the water and actuates the main flap. In light winds, it gives you more lift, and the boat pops up on the foil. Get too high, and the wand drops down even further, forcing negative lift on the flap, which brings you back down to your desired height and prevents the foils from breaking the surface.

In terms of construction, the judges praise its carbon-and-epoxy build quality and the all-up weight of 180 pounds, which makes it easy to get to and from the water. With the F101 sitting on its dolly in the boat park, going sailing is as simple as pulling back the covers, hoisting the main and launching from a dock, beach or boat ramp with minimal fuss.

“What I like about it is that it’s one of those boats that you buy and don’t need to add anything to it,” Allen says. “There’s nothing to change out or upgrade.”

For simplicity, the boat is set up with adjustments that let you ratchet up the experience as you climb the learning curve. On the rudder foil, for example, there is a clear numbering system so that as you twist the tiller extension, you change the rudder rake. The baseline setting is zero, and it’s the same for the main foil. The only thing left is to balance the forces with the mainsheet.

“When I first got up on the foils, I was thinking to myself, ‘This is too easy; I should be working harder,’ ” Powlison says. “As they said, this boat solves a lot of the problems associated with other foiling dinghies. It’s a great high-performance boat that represents the next step in making foiling accessible to the public.”

The New Befoil 16 Sport Catamaran Finally Unveiled

Do you remember the Voilavion ? Befoil 16 came from this R & D project, imagined by Benjamin Magnard, aiming to create a hydrofoil boat equipped with a tilting mast, which flew from its first sea trials.

Specifications were drawn up in collaboration with VPLP, a naval architecture firm whose reputation is well established, to create a hydrofoil catamaran that is easy to use and accessible to all: the Befoil 16. It is a 16-foot hydrofoil catamaran designed for lovers of new sensations and sailing schools, which is easy to handle, and which, thanks to its large surface area and stability, allows safe navigation over water.

The new Befoil 16 Sport

Made in Europe and assembled on the premises in Lorient, the Befoil 16 Sport is a high-quality construction thanks to the infusion manufacturing process.

This sportier version was launched at the end of 2020. The 16 Sport is lighter, stiffer and more canvasy, for performance on the water. Intended for private individuals and sailing schools, this hydrofoil catamaran adapts to all sailing programmes, to learn how to fly on the water easily and to fill up with sensations.

With its self-regulating T-foils and its 2 load-bearing rudders and glass/epoxy hulls, the Befoil 16 Sport is the latest addition to the Befoil series. In trapeze sport mode, or in comfort mode with theoptional ladders, the 16 Sport provides a great feeling of speed. The boat takes off from 8 knots and can reach up to 20 knots.

Benjamin Magnard, president of Befoil adds: “ Everyone dreams of flying on water! Thanks to the Befoil 16 Sport, all flying boat enthusiasts – whatever their level – can take off as soon as the weather is light, combining pleasure and speed! “.

The 16 Sport recently took off thanks to its distinction as “Foiler of the Year 2021” by French magazine Voile Magazine.

Hydrofoil yachts can be retrofitted on both monohull and multihull sailboats.
The International Moth class is one of the most widespread uses of hydrofoils in sailboats.
Hydrofoil yachts can achieve impressive speeds, with some reaching over 50 knots.

Hydrofoil technology has been around for over a century, with the first patent for a hydrofoil boat filed in 1898 by Italian engineer Enrico Forlanini. Since then, hydrofoil yachts have undergone significant advancements, transforming the sailing experience and pushing the boundaries of speed and performance.

The concept behind hydrofoil yachts is simple yet ingenious. By using wing-like foils mounted under the hull, these yachts can lift themselves out of the water as they gain speed. This lifting action reduces the wetted area of the hull, minimizing drag and allowing the yacht to glide effortlessly through the water.

Hydrofoil yachts come in various configurations, each designed to optimize performance and stability. Let’s explore some of the most common types of hydrofoil yachts:

Monohull Hydrofoil Yachts : Monohull hydrofoil yachts feature a single hull and employ a “ladder” arrangement of hydrofoils. These hydrofoils typically have a dihedral angle of around 50 degrees and are complemented by a stabilizing rudder foil. This configuration provides stability and control, allowing the yacht to sail smoothly on foils.

Multihull Hydrofoil Yachts : Multihull hydrofoil yachts, such as catamarans and trimarans, offer increased stability and performance. These yachts use wider planforms, allowing for greater lift and control. Some multihulls utilize three foils, with two main forward foils providing lift and a horizontal foil on the rudder for additional control.

Hydrofoil Catamarans : Hydrofoil catamarans, also known as foilcats, combine the stability of a catamaran with the speed and efficiency of hydrofoils. These yachts can achieve impressive speeds while maintaining excellent stability, making them popular choices for racing and recreational sailing.

Hydrofoil technology has found its way into various sailing classes, revolutionizing the way we sail. Let’s take a closer look at some of the notable hydrofoil classes:

International Moth : The International Moth class is one of the most widespread uses of hydrofoils in sailboats. These single-handed dinghies feature foiling capabilities, allowing sailors to achieve incredible speeds and maneuverability. The class has seen rapid growth since 2001, with carbon fiber foils and advanced design techniques pushing the boundaries of performance.

Waszp : The Waszp class is similar to the International Moth class but utilizes aluminum foils instead of carbon fiber. This makes the Waszp more accessible to a wider range of sailors while still providing the exhilaration of foiling.

AC75 : The AC75 is a foiling monohull sailboat class used in the 2021 America’s Cup. These impressive yachts can reach speeds of up to 50 knots, showcasing the incredible potential of hydrofoil technology in the world of competitive sailing.

IQFoil : The IQFoil windsurfer class was selected by World Sailing for the 2024 Summer Olympics. These windsurfers feature hydrofoils, allowing athletes to glide above the water and achieve impressive speeds.

IMOCA 60 : Originally designed as non-foiling offshore racers, the IMOCA 60 class has embraced hydrofoil technology. These yachts now feature S-shaped daggerboard foils, providing partial foiling capabilities and enhancing performance in various conditions.

F50 : The F50 sailboat class is used in the SailGP series and is the first sailboat class to break the 50-knot barrier during a race, with a top speed of 52.2 knots. These high-performance catamarans showcase the incredible speed and agility that hydrofoil technology can offer.

Several brands have embraced hydrofoil technology, offering a range of hydrofoil yachts to cater to different sailing preferences. Here are some notable hydrofoil yacht brands and models:

Gunboat : Gunboat is a renowned brand in the world of luxury hydrofoil yachts. Their models, such as the Gunboat 68 and Gunboat 72, combine performance, comfort, and elegance, providing an exceptional sailing experience.

GC32 : The GC32 is a hydrofoil catamaran designed for high-performance racing. This foiling catamaran offers thrilling speeds and precise control, making it a favorite among competitive sailors.

AC72 and AC45f/AC50 : These hydrofoil catamarans were used in the America’s Cup, showcasing the cutting-edge technology and innovation in the world of hydrofoil yachts. These yachts pushed the boundaries of speed and performance, captivating sailing enthusiasts worldwide.

Nacra 17 and Nacra F20 : Nacra is a well-known brand in the world of multihull sailing, and their Nacra 17 and Nacra F20 models feature hydrofoil capabilities. These yachts offer a perfect balance of speed, stability, and maneuverability, making them popular choices for recreational and competitive sailing.

Hydrofoil yachts offer a range of advantages that make them appealing to sailors seeking speed, performance, and an exhilarating sailing experience. However, they also come with some drawbacks. Let’s explore the pros and cons of hydrofoil yachts:

Advantages:

Increased Speed : Hydrofoil yachts can achieve impressive speeds, thanks to reduced drag and increased lift. This allows sailors to cover more distance in less time, making hydrofoil yachts ideal for racing or simply enjoying the thrill of speed on the water.

Smooth Ride : By lifting the hull out of the water, hydrofoil yachts provide a smoother and more comfortable sailing experience. The reduced contact with the water minimizes the impact of waves and chop, resulting in a smoother ride even in rough conditions.

Improved Efficiency : Hydrofoil yachts are more efficient than traditional sailboats, thanks to reduced drag and improved lift. This increased efficiency translates to better performance and reduced energy consumption, making hydrofoil yachts an environmentally friendly choice.

Disadvantages:

Complex Design : Hydrofoil yachts require a more complex design compared to traditional sailboats. The addition of foils and the associated control systems can increase the complexity of the yacht, requiring more maintenance and potentially higher costs.

Learning Curve : Sailing a hydrofoil yacht requires a certain level of skill and experience. The handling and control of a hydrofoil yacht can be more challenging compared to traditional sailboats, requiring sailors to adapt to the unique characteristics of foiling.

Higher Costs : Hydrofoil yachts, especially high-performance models, can come with a higher price tag compared to traditional sailboats. The advanced technology, materials, and design required for hydrofoil yachts contribute to their higher cost.

How fast is the hydrofoil racing yacht?

Hydrofoil racing yachts can achieve impressive speeds, with some models reaching over 50 knots (57.5 mph or 92.6 km/h). The F50 sailboat class, used in the SailGP series, holds the record for the fastest sailboat class, with a top speed of 52.2 knots (60 mph or 97 km/h).

What does a hydrofoil do to a boat?

A hydrofoil lifts the hull of a boat out of the water as it gains speed. This reduces the wetted area of the hull, minimizing drag and allowing the boat to achieve higher speeds. The lifting action of the hydrofoil also provides a smoother ride by reducing the impact of waves and chop.

BOAT SPEEDS FAR BEYOND DOUBLE WIND SPEED CAN BE ACHIEVED . Enjoy high speed foiling with top speeds far beyond 25 knots – in ideal conditions up to 30 knots.

CONTROLLED FOILING EVEN IN THE UPPER WIND RANGE BEYOND 22KNOTS OF WIND SPEED – supported by the new FlySafe® Automatic Foil System.

FOILING PLEASURE AND PERFORMANCE ALSO IN CHOPPY WATERS

FREEDOM ! FLYING SOLO OR OPTIONAL WITH CREW . You have the choice. No manhunt for crew. But still enjoy the opportunity of taking a friend or family to fly with you. Up to 140kg of crew weight. (To keep the boat and especially the mast light, we specified the iFLY15 components intentionally not for double trapeze.)

NO HOISTING AND LOWERING OF DAGGERBOARDS while sailing. (Only for beaching or in shallow waters.)

FREEDOM TO SWITCH BETWEEN FLYING MODE OR SAILING AS A CONVENTIONAL CATAMARAN (with at least the leeward hull touching the water). Within seconds iFLY15 can be switched to Non-Flight mode, even while sailing. In that mode, iFLY15 will not take off, but the foils will still create lift and give an extra agile sailing behavior, which is on the same time very stable as rudder Foils will avoid pitch poling. Non-Flight mode is providing additional security in extreme high wind speeds. It is also useful for less experienced sailors or in all situations, where taking off is undesirable (e.g. in the harbor or while towing…).

EASY TO LEARN FLYING BY AVERAGE SKILLED AND TRAINED SAILORS

EASY BEACHING AND SLIPPING , as simple as with any conventional beach catamaran by using a standard catamaran beach trolley. Foils remain flat under the keel, with the daggerboard lifted as on a conventional catamaran.

SIMPLE TO DISASSEMBLE PLATFORM . Width of 2.50m is also road legal in most countries for horizontal transport without disassembly.

DAGGERBOARDS CAN BE PLUGGED IN FROM ABOVE and Foils securely anchored from below with one central screw.

FAST SET-UP OF THE iFLY15 FROM ROAD TRAILER TO SAILING . Simple rigging the mast, no genacker boom, no foresail, no spi.

SILENT AND CALM PLANING ABOVE THE WAVES . Flight height of up to 90cm, avoiding even high waves below.

EASY TO FOIL THE JIBE (without landing). Stable maneuvers are made easier by the fact that the four T-Foils always remain in the water.

Hydrofoils for Sailboats

By By Steven Callahan
Updated: July 29, 2020

Hydrofoils have been providing dynamic lift since fish sprouted fins. And people have been employing foils ever since they first put paddle to water, and certainly since adding keels and rudders to boats. But the modern, flying America’s Cup boats, kiteboards, Moth dinghies, shorthanded offshore thoroughbreds—these are all playing in a new world in which the terms “hydrofoils” or “lifting foils” describe those oriented to raise a hull or hulls from the water. In these racing realms, if you ain’t got foils, you ain’t got nothin’.

Lifting foils that allow these boats to sometimes home in on three times the wind speed might appear to be of little interest to cruising sailors, but with such common cruising features as self-steering and autopilots, self-tailing winches, rope clutches, fin keels and faster hull shapes all having been passed down from the racing scene, one must ask, “What promise, if any, do hydrofoils hold?”

Lifted or partially lifted boat patents extend back to 1869, but workable watercraft took roots along with early flight. Italian Enrico Forlanini began experimenting with foils in 1898. In 1906, his 1-ton 60 hp foiler reached 42.5 mph. Alexander Graham Bell’s HD-4 Hydrodrome flew on Bras d’ Or Lake at 70 mph in 1919. And several sailing foiler patents began appearing in the 1950s. Notably, JG Baker’s 26-foot monohull, Monitor, flew at 30-plus mph in 1955. Baker experimented with a number of foil configurations, and at least built, if not used, the first wing mast. The first offshore foiler was likely David Keiper’s flying trimaran, Williwaw , in which he crisscrossed the Pacific in the 1960s.

By the 1980s, numerous speed-trial and foil-enhanced offshore-racing multihulls showed huge promise, and have since evolved into behemoth trimarans clocking 30 to 40 knots continuously for long periods, not to mention the monohulls in the Vendée Globe (and soon the Ocean Race) that are capable of speeds exceeding 30 knots. But as boat designer Rodger Martin once reminded me, “If you want a new idea, look in an old book.” He was right. The fully foiling monohulls that will compete in the 2021 America’s Cup will bring things back full circle to the foiling monohull Monitor .

Fluid Dynamics Primer

Any foil—a wing, sail, keel, rudder or lifting foil—redirects the flow of fluid (air included), creating high- and low-pressure areas on opposite sides of the appendage, while developing lift perpendicular to the foil’s surface.

Advancements in foiling science is due in part to the hundreds of foil shapes that were tested, with tabulated results, by the National Advisory Committee for Aeronautics, the forerunner of the National Aeronautics and Space Administration. For the better part of a century now, aircraft and boat designers have been able to choose from a spectrum of refined foil sections that produce predictable amounts of lift and drag for known speeds of fluid and angles of attack, or the angle at which the foil passes through the fluid. Sections of efficient faster foils, as seen on jets or as we flatten our sails to go upwind or reach high speeds, have smaller nose radii and are thinner, with the thickest section of the foils farther aft, up to nearly halfway toward the trailing edge.

The most efficient foil sections at slow speeds are fatter, with the maximum thickness farther forward, and with larger nose radii, than faster foils. The angle to fluid flow or angle of attack also is greater. We see these slower foils on wings of prop planes and sails when off the wind or in light conditions.

Most sailors are familiar with traditional foils on boats, the teardrop sections of keels that produce lift to weather, reducing leeway, and of rudders, allowing them to steer. Even a flat plate can be a foil, but these tend to be inefficient. Such a shape is prone to fluid separation from the surface, meaning they stall easily, and they maintain poor lift-to-drag ratios. Even keels and rudders are somewhat lift-compromised because they are symmetrical and have to work with fluid coming from either side, whereas lifting foils are more like aircraft wings or propellers, with asymmetrical sections honed for performance in a more stable, fluid flow.

The point is, any foil can be employed at various angles to the surface to prevent leeway, produce increased stability, or help lift the boat out of the water. But those not required to work with fluid flowing from opposite sides can then be honed to maximize lift and minimize drag. Asymmetrical foils were used on boats like Bruce King’s bilgeboarders, including Hawkeye , back in the 1970s. And, designers, including Olin Stephens, had previously employed trim tabs behind keels to improve keel performance.

Sails, which are heeled airfoils, not only drive the boat forward, but they also produce downforce, actually increasing the dynamic displacement of the boat. To counter this and keep the boat sailing more upright, multihull designer Dick Newick first employed slanted asymmetrical hydrofoils in the outer hulls of his small charter trimaran, Lark , in 1962. A portion of the lift developed by the hydrofoil resisted leeway, while a portion worked to actually lift the leeward hull, keeping the boat more upright and reducing dynamic displacement and drag.

Anyone who has ridden on even a foil-stabilized boat will know how riding at least lightly on the waves, and especially above them, beats smashing through them. When boats lift off, everything gets a lot smoother, drag falls away, and the boat accelerates.

Cruising on Foils

But why would a cruiser want to whip over the sea? Wouldn’t this demand an inordinate amount of attention by the crew? Would lifting foils even be applicable to a boat that must have substantial displacement to carry crew and stores? Aren’t cruising-boat hydrofoils an oxymoron?

Maybe, but I believe our boats’ hulls are likely to sprout fins much as fish have as we orient foils to more efficiently resist leeway, add stability, aid steering, reduce drag, increase comfort, allow for shallower draft, and enhance wider variations in hull shapes.

Boats have gotten increasingly wide through the years to advance form stability, improve performance (primarily off the wind), and boost interior volume. But the downside is that fat boats tend to slam more upwind. What if you could reduce dynamic displacement of the boat and lift that hull even partially from the water? The result would be less slamming, especially upwind.

At the same time, what about narrower boats that are known for being more seakindly, especially when closehauled, but lack form stability to carry adequate sail area for powering upwind, and tend to roll badly downwind? Or shallow-draft vessels that are lovely for cruising, but again, tend to suffer from reduced stability? Foils can give that stability back.

Looking ahead, boat designers might choose to reduce ballast, making up for it with a foil. In short, lifting foils can reduce boat drag and motion while increasing power and performance.

Pitching also does no favors for speed or crew comfort. Foils can come into play here as well. Foils parallel to the sea’s surface resist motion up and down, and a lifted boat skating above chop also is less prone to hobby-horsing through waves. Multihulls have always been particularly susceptible to pitching for a number of reasons, but watching videos of multihulls sailing to weather show an obvious huge advantage that foilers have compared with nonfoilers. Offshore multihulls now routinely employ T-foils on the rudders to control the fore and aft angles of the boat (attitude), a feature easily adaptable to any vessel.

OK, so what’s the cost? Obviously, the more things sticking through the hull, especially if they are retractable, the more it’s going to impact the interior. There would be added weight, complexity and cost. Foils also create noise, and there’s susceptibility to damage from hitting stuff. And let’s not forget compromises with shapes, purposes and things not yet imagined.

As for damage, it’s possible to fold the foils back into the hull. Think swinging center- boards or actual fish fins. Daggerboardlike foils can at least employ shock-absorbing systems similar to the daggerboard arrangements found in many multihulls. This includes weak links that are outside the hull, so if a foil is struck, it frees the foil to fold back or to come off before being destroyed or damaging the hull. Or, foils might hang from the deck rather than penetrating the hull, allowing them to kick up (and to be retrofitted to existing boats). These configurations also relieve the interior of intrusions, and keep the noise more removed from it. I have no doubt that numerous talented designers will be exploring all kinds of options and compromises in coming years, finding ways to make foils both practical and more than worth the compromises.

Sailing more upright, shallower draft, speed, comfort—what’s not to like? Just what is possible? I have a feeling the cruising community is about to find out.

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

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

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.

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

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

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.

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.

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.

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.

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.

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!

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

Homebuilt Hydrofoil for Sailboats test sailed – end to hiking out?

Launching our Homebuilt Foil stabilised dinghy – this article is to use our experiment as the basis for low cost foiling that anyone can use to build or modify a boat – it sailed nicely in 5 to 10 knots and I didn’t have to do any hiking.

This is not about outright speed (wrong hull type for a start). It is about stability without hiking out. On the other hand if it works on this boat … it will work on anything!

No worthwhile video I am afraid – little wind when the photo boat was available on Sunday. We will get some next weekend with luck.

This is part of a four article set

Part 1 – Sailing Trials in 5 to 10 knots of the hydrofoil stabilised dinghy.
Part 2 – Building a Hydrofoil Stabilised dinghy – and proposal for comparison using any hull. Up later today
Part 3 – Video in more wind – Next weekend if there is wind!
Part 4 – Three Homebuilt hydrofoiling Projects – democratising foiling! Up Next week

Myth busting Foiling Boats – you don’t need a factory and you don’t need carbon fibre.

Everyone knew this once – because the recent history of making foiling work was achieved with homemade foils using timber and fibreglass.

The great Myth about foiling boats is “that it is high tech and everything has to be carbon”. But all the significant development in the Moth Class was with wooden hydrofoils that were fibreglassed with only small amounts of carbon or stainless steel.

The specification itself is to provide a basis for cheap experimentation and comparisons of performance.

The Foiling Moths advanced so quickly because there was a specification and people messed around with the spec and shared information. Wood and glass make fast modifications to homebuilt hydrofoils easier (and cheaper)

Maybe even racing if anyone has a mind to. But also as the basis of comparison with boats in other areas.

What does it feel like – a homemade foil stabilised boat upwind

We had good luck for the first day of testing – 5 to 10 knots and a well sailed Oz Goose as a pace boat. Started to get a feeling of the speed potential.

This section is about that.

Second day when we had a chase boat with cameras – of course the wind died. Hopefully we will have video next weekend.

The lateral foil to leeward needs to be kept in the water in the lulls. In 5 to 10 knots this meant sitting a little to leeward.

Initially as gusts hit I would follow instinct and make the wrong move. Hiking out brings the foil would to near the surface, would ventilate (suck air from the surface) and then the boat heel and slow.

Well … it is obvious … sit to leeward in the lulls, when the gust comes let the foil do the work – don’t move out to windward.

No Hiking. But with the same sail they were hiking in the accompanying Oz Goose .

So what to do when a boat with a lateral foil heels?

Don’t move your butt! Ease the sail and point a fraction lower to get the boatspeed up. The lateral foil starts to rise because of more lift – fly it up again.

Then I could wind in the sheet again to increase the heeling force. It is a feeling like flying. Boat heels then get speed without increasing the heeling force. Wind drops, move your body a little to leeward. Sheet loads seem higher – greater stability than hiking?

It becomes quite mesmerising watching the foil a foot or two below the water surface.

As the foil produces lift there is a depression in the surface of the water above the foil – which turns into a series of waves that make up the foil wake stretching back. It it like being followed by a small Loch Ness Monster.

It does also show that the homemade hydrofoil is developing lift at low speed.

The photo is at a very low windspeed/boatspeed. These wavelets go quite a way back. On Saturday with more wind and boatspeed I thought the transom was digging in and making a commotion.

But, it was the combination of the hull’s sternwave and the foil’s wake making a noisy quarter wave on the leeward side

So this is the exciting thing – not pure speed but less physical effort

At the moment many foiling systems are more or less being retrofitted to conventional boats.

Many of those boats are very wide – like the IMOCA 60s or some of the supermaxis.

Interestingly it is more moderate beam boats that win most races. They are faster in light winds, faster upwind and can sail deeper angles downwind without losing speed. A bit easier to steer too.

The question is … if we gain stability from a lateral hydrofoil – what is the beam for?

Canoes are light, fast and easy to store and transport. But can be hard to hold upright. PERHAPS this is a good place to start.

Another aspect is that modest length boats for disabled sailors have limited stability (and speed) because the centre of gravity of the crew is so high.

I also think about what will happen when I can’t hike out so hard. That’s why I win Oz Goose races. But I can certainly feel it in my 60 year old bones. The day is not close, but it is coming.

The inspiration of the Quant 28 and 17

Normally a keelboat this size without a canting keel would need 5 to 7 people on the rail.

Same lateral foil but a more beautiful version by Hugh Welbourne for Quant Boats in Switzerland.

The lateral foil is the simplest possible lifting foil.

Quant 28 defying gravity with Dynamic Stability Systems

In terms of stability – see how the crew on the Quant 17 go from full trapezing and hiking to sitting inside the boat when the foils are deployed and to leeward as soon as the boat has any downwind component.

Testing the Q17 on Lake of Garda E sound

I’m interested in the stability component.

In homebuilt hydrofoil boats Ian Henehan’s modified Oz Goose saw him chuck the hiking wings and start sitting inboard too.

Texas Goose - Foiling with No Hiking Wings

It was like this with a hiking rack before – no longer needed. Simplification and less effort.

Perhaps: an advantage of some rocker for foiling dinghies

We didn’t fit a rudder foil at this stage – even though we built the rudder extension.

The purpose of a rudder foil on all foilers is to hold the main foil at an optimum angle of attack. Usually the rudder foil is adjustable in some way to allow the adjustment of the angle of the main foil.

If the rudder foil is sent lower then the angle of attack of the main foil is increased.

But with the 8ft boat with the extreme rocker it was possible to move back to increase the angle of incidence of the main foil. The base angle is 2 degrees Angle of Attack relative to the static waterline of the boat.

In the gusts of around 10 knots, going upwind, it was possible to move forward or back to reduce or increase lift – speed changes from doing so were instant. So where you sit in/on a rockered boat is a critical tuning factor.

Less rocker might be OK, but some rocker is going to be important. Maybe concentrated in the back end of the boat. I’m not sure if the foil fitted IMOCAs do this with water ballast.

Overview of comparison sailing the hydrofoiled boat against the larger Oz Goose

This is not necessarily a question of speed, though it is nice to get.

Our 8ft boat is absolutely sub optimal as a foil stabilised boat.

It is short, so potential hull speed is low – 8ft long. This limits foil lift (square of velocity).
It has a lot of rocker (fore and aft hull curve)
Crew weight is a very large part compared to the boat volume – it was meant to be a prototype kid’s boat but the curved cockpit was too hard to build. So we repurposed it.

Saturday it was sailing around in company with Job and Jazmine in a Goose who I compete against in that class. They are among the top sailors in the Oz Goose so I know the speeds they hit. And the new boat has an Oz Goose Rig but is only 8ft to the Oz Goose’s 12ft length.

In the lighter patches it was noticeably slower than the Goose, but it was still sailing properly (felt normal/good). It was a faster choice to retract the foil. Pushed out to windward the hydrofoil is above the water to reduce the wetted surface.

With a bit more wind and foil deployed it started to equal the goose upwind. This is not something the shorter boat should be able to do.

The biggest difference – no hiking. While Job and Jazmine were hiking in the Oz Goose I found it best to move to keep the foil in the water in the lulls – which meant I was sitting centrally or to leeward and not hiking in the gusts. It is low effort sailing.

Downwind differences – was the 8ft foiled boat able to stick with the 12ft Oz Goose?

Downwind the Goose should have walked away from the smaller boat. I’ve a lot of experience with the 8ft Oz Racer and a GPS and know the boat tops out at around 4.2knots or just about 5. It can go quite a bit faster (up to 8knots) but it takes a lot of wind and it drops back to the 4 to 5kn range as soon as the gust drops slightly. The Goose, however just loves to accelerate into the 6 7 or 8 knot range and on stronger wind days gets up in the 8 to 12 knot range. And beyond.

So the Goose should get away from the shorter boat.

It did … but not too dramatically. More comparative trials to come.

Now we hope there is more wind next Saturday when we have the photographer and a chase boat.

Merci Daniel!

Can you provide a link here to the article on your website.

Also we hope to get more wind to show how the foil behaves. We had one day of moderate wind but no photo/video boat. But last three weekends have had very light wind – sub 5kn. A more active video when Poseidon grants our wish.

Best hydrofoil boats: 6 of the most spectacular foiling motorboats money can buy

Electric boats
Top stories

Foiling technology has really taken off in the past few years. We pick out 6 of the best hydrofoil boats you can buy right now…

With its roots in the 19th century, foiling technology is as old as the hills, but in the past five years we’ve noticed an explosion of hydrofoil boats coming onto the market.

In part inspired by the foiling raceboats of the America’s Cup , the popularity of foiling is easy to understand – fuel efficiency gains are substantial, noise is almost eliminated (particularly if your foiling boat also happens to be an electric boat ) and they look as cool as a snowman in a freezer!

To help you understand the dizzying array of foiling boats available right now, we’ve put together the following guide to what we think are the most promising designs out there.

6 of the best hydrofoil boats

SEAir foiling RIB

Founded in 2016, French yard SEAir builds foiling RIBs, having been inspired by the speed of foiling racing yachts.

We tested their 5.5m model back in 2018 and since then they have expanded their range to cover superyacht chase boats, commercial and military vessels.

Our tester recorded a top speed of 32 knots, with the foils doing their best work at around 20 knots, but SEAir claims that 42 knots is possible in the right conditions.

Enata Foiler

Dubai-based Enata Marine added a healthy dose of glamour to the world of foiling boats in 2018 with the launch of its Foiler.

In addition to a superyacht tender-worthy exterior, this 32fter includes a bow window for spectacular views while underway.

A 40-knot top speed and a 190nm range makes this a very appealing option, although the premium price tag of $938,000 may put some off.

Princess R35

When British boatbuilding giant Princess Yachts got in on the foiling boat game in 2019 with a 35ft carbon-fibre dayboat, we knew that things had really taken off.

While the foil-assisted R35 may not have the spectacular cruising-above-the-waves appeal of some other foiling boats, it is highly efficient, beautifully designed (in collaboration with Pininfarina) and handles like nothing else we’ve ever driven.

In our review, we praised its rare combination of agility, refinement and stability, with spray kept in check impressively at high speeds.

Candela C-8

Swedish firm Candela burst onto the scene in 2021 with its debut, the Candela C-7 , which was billed as the world’s first electric foiling boat, but it was the 2022 launch of the Candela C-8 that really moved the game on.

Available with a 69kWh battery, adapted from the Polestar 2 electric car, owners can expect a range of 57nm at 22 knots, more than enough for dayboat use.

The consumption figures are truly staggering, with Candela’s figures suggesting that the C-8 is more than 12x more efficient than an equivalent 300hp outboard powered sportsboat.

Iguana Foiler

Not content with being at the forefront of the amphibious boats market with its caterpillar-track offering, French yard Iguana has set its sights on the world of foiling too.

Announced last year, the Iguana Foiler will be powered by the world’s most powerful electric outboard engine, the 300hp Evoy Storm .

Having tested both the engine and the boat separately, we can’t wait to see the result when they come together with the added advantages of foiling technology. Watch this space…

Mantaray M24

Another exciting model in the hydrofoil boats pipeline, this 24ft runabout is particularly interesting is its simplicity. Unlike its main foiling rival, the Candela C-7, the Mantaray M24 requires no complicated electronics to ‘fly’.

Instead it uses the builder’s patented mechanical hydrofoil system, which it has trademarked as Dynamic Wing Technology or DWT. The technology is said to be the result of ten years’ development work and uses a retractable T-foil in the bow and H-foil amidships that self-stabilise mechanically.

This allows it to lean naturally into corners and ride serenely over waves without relying on a network of sensors and algorithms to monitor and adjust the foils. If it proves effective this could drastically reduce the cost and complexity of foiling boats, while simultaneously increasing reliability.

which hydrofoil is best on a small outboard?

I have a 12" whaler clone trihull that rides front high under acceleration no matter how you distribute weight, I have a nissan 9.8 four stroke that is heavier than its 2 stroke brother so I am going to try a stabilizer for my boat to get a better ride even if I lose a coulple of mph off of the top end. Whats your vote for the best one?

Re: which hydrofoil is best on a small outboard? I think a trim tab would fix your problem not a fin

Supreme Mariner

Re: which hydrofoil is best on a small outboard? Although the claims for them on the package may say this is a good application for a fin, its not what they do well. You need tabs.

Mar 23, 2009

Re: which hydrofoil is best on a small outboard? This is a 12 foot boat, I think tabs will cost more than the boat.

Re: which hydrofoil is best on a small outboard? Smart Tabs are not that much. I will try to explain my problem with the foil. Let's look at it from a stability stand point. a foil creates a pivot point along the keel of your boat. Picture trying to trailer your boat with only the center bunk. The boat will fall to one side. That is why there are bunks on each side in addition to the center bunk. The same holds true with the foil. I took a large wake sideways from a speed boat while running about 30mph in my old 19' cuddy. My cuddy almost rolled over and scared my kids so bad I had to buy a pontoon to get them back on the water. Trim tabs provide stability on the outside of the transom and actually keep the boat stable. The foil also adds additional stress to your transom. Adding the Smart Tabs to my cuddy was the best $130 I had ever spent and the new owner loves them.

Re: which hydrofoil is best on a small outboard? You can always pick up a low cost fin and give it a try, if you don't like it just take it off.

Re: which hydrofoil is best on a small outboard? Just to be the voice of the other side, on my 19 foot boat the SE Sport foil works great. I see that they now have a way of attaching it without drilling your cavitation plate. Iboats sells them. Go for it.

Re: which hydrofoil is best on a small outboard? I've seen it argued the a fin on the motor puts stress on the motor mounts. Look at it this way- you're adding a lot of lift to the motor mounts that they weren't designed to handle. Start slamming over waves, and it makes it worse. I really don't know if that's true or not, but my '83 Johnson 35 had all of the motor mounts broken when I got it. I took the fin off.

Re: which hydrofoil is best on a small outboard? I have a Stingray on my 7.5HP and am happy with it's performance. It came with an outboard I bought and after a couple months I took it off to see how it would affect the boat's handling/speed. There was no performance gain with it off and the boat was a lot slower coming on plane,,, so it went right back on.

'Flying over water': Why this electric car-boat vehicle will move like a plane

The trident ls-1 is expected to reach speeds of up to 95 mph on land and drive directly onto the water. the first models are planned to be sold by december 2025..

Flying cars are no longer a thing of the future, and neither is the need to choose between commuting on land or sea, at least for those who live by the water.

Poseidon AmphibWorks, a company based in San Diego and Miami, plans to revolutionize the car-boat vehicle by delivering a what it says will be a tranquil experience, whether you're on a busy freeway or in a bustling bay. Since most existing amphibious vehicles move over water as bumpy as a jet ski, CEO and founder Steve Tice said he sought to create a vehicle for the day-to-day commute.

Since 2021, Tice and amphibious vehicles expert Andy Langesfeld have been working on the Trident LS-1. As a hydrofoil, the vehicle features blades, or vanes, that elevate the body of the boat for a smoother ride. Hydrofoils remove 60% of the drag oversea and make steadier turns because the hull is out of the water, Tice said.

The Trident LS-1 will be the world's first hydrofoil electric car-boat designed to prevent seasickness caused by a vessel's erratic motion on water, according to the company.

"People that couldn't even ride in small boats will finally be able to ride without any motion sickness. So basically flying over the water," Poseidon AmphibWorks founder Steve Tice recently told USA TODAY. "Because gravity is still pushing you through your rear end, you still feel like you're on an airplane. When you make a turn you don't feel strange, it feels natural."

Three-wheel car-boat fits four people

The electric three-wheel vehicle will reach speeds of up to 95 mph on land and drive directly onto the water along a launching ramp, Tice said. For those who live near water, the Trident LS-1 will use multi-modal transportation for getting to the office or having a weekend fishing trip.

The vehicle features three permanent seats, including a center driver seat and two rear ones, as well as an additional fold-down center seat, Tice said.

Drivers will be able to park the 7 foot-long vehicle in their garage, a key requirement for the engineering company. The vehicle also removes the need for a tow vehicle, which runs the risk of falling into the water while releasing a boat, Tice said.

Tice said the company decided the vehicle would run on three wheels to avoid adding extra weight while maintaining the stability of any four-wheeler. He added that the car-boat will have all necessary safety feature from air bags, a tubular aluminum roll cage and multiple cameras.

'Basically flying over water'

As a hydrofoil, the Trident LS-1 is a car-boat that moves like a plane. While not made for high surf, the vehicle ensures riders avoid all the ripples of 1- to 2-foot waves.

"You're basically flying over the water at about 3 feet," Tice said.

When driving on land, Tice said the hydrofoil's vanes, or blades, retract into the vehicle so they can't be damaged by road objects like rocks. When moving on water, users have control over much of the vanes are deployed, depending on the depth of the water.

Tice said it's also a "vey maneuverable boat" that uses thrusters that turn on a dime, allowing the vehicle to stay in one spot over water for fishing or head toward any direction.

Vehicle to be sold in $100,000 to $130,000 range

The Trident LS-1 is expected to be sold directly to the consumer at $100,000, Tice said.

Poseidon AmphibWorks will work with a number of dealers who will provide service and local support for around an additional $30,000.

With proper boat registration and a driver's license, anyone will be able to take the car-boat for a spin.

"You don't need a special license," Tice said. "We are certainly going to train people. We don't want them to crash this thing."

The company said the vehicle will appeal to a number of markets, including people who live on the coast, near waterway rivers or on islands. He added that it will also appeal to RV owners who can eliminate the burden of having to tow two vehicles, as well as yacht owners who don't want to steer their home to shore to buy groceries. He also said it makes the perfect starter boat for electric car owners.

The company is looking into commercial taxi uses, delivery services and military interest, Tice said.

Trident LS-1 joins league of car-boats

Car-boats are not a thing of the future and the Trident LS-1 is far from being the first.

The Amphicar was built in Germany in the 1960s. The small but heavy amphibious vehicle reaches speeds of 7 mph on water and 70 mph on land.

In 1999, the first WaterCar vehicle was introduced, and in 2007 it earned the Guinness World Record for being the fastest amphibious vehicle at 60 mph across water and 127 mph on land.

Other amphibious vehicles include the Amphi-Ranger , Gibbs High Speed Amphibians , the Hobbycar and the Dutton .

Prototype to be completed later this year

The creators have not started building and are currently finalizing the plan for the prototype, expected to be finished by the end of the year, Tice said.

"By December 2024, we will have a prototype in the water here in San Diego," he said.

By then the company plans to begin accepting deposits for the vehicles. Around December 2025, the company will sell to California customers so they can be helped at their San Diego location in case of service. Tice said non-California customers should also be able to pick up a Trident-LS1 in California at that time and hopes the company can ship to out-of-state customers by June 2025.

"It's not a vehicle for everybody," he said. "But if you're within a distance of a body of water that you'd like to recreate at or wish you could, there's your first boat."
