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.

Boat of the Week: Meet the ‘Patriot,’ the New Lightning-Fast America’s Cup Foiling Yacht Representing the US

After being airlifted 9,000 miles from the factory, the 45-foot sailing racer exceeded designers' initial expectations by zigzagging around the auckland waterfront at insane speeds., michael verdon, michael verdon's most recent stories.

Patriot , the just-launched America’s Cup racing yacht representing the United States, completed its first week of sailing last week in New Zealand . The New York Yacht Club’s representative team, American Magic, tested the potential of a design that had only been proven by computer simulation. The 75-foot navy-hulled Patriot , which just days before had been shipped by cargo plane 9,000 miles from Rhode Island, streaked across the Auckland waterfront, zigzagging on its foils, videos suggesting it reached its “sound barrier,” or top speed, of an estimated 50 knots (America’s Cup teams don’t like to talk about top speeds), or 57 mph.

“We went off the dock thinking that if the breeze filled in, we’d have a good sail,” Terry Hutchinson, skipper and executive director of American Magic, said after the sail. “Straight away, we came into 21 knots [of wind pressure], and we were into it. Despite having a brand-new boat that we were all excited about, the whole session felt normal. That’s a great validation of our shore team and all of the work put in since we launched the Mule in 2018.”

“The Mule” was the first prototype that American Magic built to train its crew on at its facility in Pensacola, Florida, and that basic design was followed by Defender , a more complex boat that has been decommissioned since Patriot ’s arrival. Like its competitors Lunna Rossa from Italy, Britannia from the UK and the America’s Cup defender, Te Aihe from New Zealand, American Magic won’t divulge technical details about Patriot , beyond the fact its steering station is more forward than on Defender .

The 75-footer is clearly fast, even out of the box, and for the next three months, designers and specialists will tweak the carbon-fiber hull and 1560-square-foot mainsail to make it even faster.

The world’s foremost sailing event, the America’s Cup has been around since 1851, though the last three Cups were more like Formula One racing, compared to the stately, slow-sailing monohulls of previous generations. The last three Cups have all been designed around foils, starting in 2013 with the AC72, and then three years ago, the boats became smaller, and much more nimble, 50-ft. catamarans that not only accelerated like an F-22 Raptor, but could nearly pivot on their own axis.

The last-generation cats were a bit too wild, so the powers that be came up with the current AC-72 class using a one-design rule where all competitors had to use common parts. The idea was to level the playing field. Organizers supply some parts of the boat, including the mast, rigging, foil-cant arms and hydraulics. The boats—16 feet wide with a crew of 11—are also built of lightweight composites because they’re designed to fly, rather than plough through the water.

While America’s Cup teams do not release top speeds, it’s estimated that the AC75 boats break the Cup’s “sound barrier” at about 50 knots, or 57 mph.  Courtesy Will Ricketson

Patriot ’s foil-cant arms are also designed to move both under or outside the boat to provide the leverage to keep it upright. If it does capsize, the crews can right the boat much easier than the previous generations of foiling racers. Another new evolution for this America’s Cup is the twin-skin mainsail on the 87-foot-tall mast. The double-sail skins combine with the spar to generate the power the AC75 needs to foil. On the last two generations, the sails were much stiffer sail-wings that many non-Cup racers complained about because there was no trickle-down technology for the rest of the sailing world.

Beneath the water, Patriot also has an interesting breakthrough design. The foil-cant system uses new technology that employs a battery-driven, hydraulic-power unit to raise and lower the strong, but very heavy, foil-cant arms, that give the boat its stability and speed. As the boat changes tacks, the cant system is activated, placing one hydrofoil in the water, and lifting the other one out, where its weight becomes ballast.

Beyond the sail plan and hull design, the foil wings at the end of the arms will be another of Patriot ’s secret weapons. American Magic designers will have the ability to create any design they believe will be most effective to give the boat an edge over competitors, and the next month will be devoted to trying new shapes and sizes.

Considering the America’s Cup’s ambitious timetable, and the unexpected time pressures Covid-19 put on design and production of Patriot in Rhode Island, it’s amazing that this yacht came through so well. “This team didn’t exist three years ago, and now we have three boats built and two AC75s launched,” said Marcelino Botin, American Magic’s lead designer. “The first thing we need to focus on next is to make sure the new boat is sailed the way we want it to be sailed.”

Botin said this initial “analysis” phase will be critical to future modifications to the design. “We are all interested in knowing how the boat performs compared to our predictions and compared to our previous boat,” he says.

Hutchinson says that Patriot ’s initial performance was encouraging, especially on its first gybe. “We had a great nosedive, and that was exciting,” he said. “It was nothing that we haven’t seen or done on our other boats, and our familiarity with Patriot will increase rapidly over the coming days.”

The powerful foils allow Patriot to tack and jibe at high speeds, and to self-right if it capsizes.  Courtesy Will Ricketson

Helmsman Dean Barker described the boat’s performance as “lively.”

After the America’s Cup World Series and Christmas Cup from December 17 to December 20 will come the Prada Cup Challenger Selection Series, from January 15 through February 22, 2021, where Patriot will compete against Luna Rossa and Britannia II for the challenger title. The winner of that event will then compete against Emirates New Zealand for the America’s Cup, which runs from March 6 through 15, 2021.

The boat’s name ‘l’Hydroptère’ was derived from two Greek words: hydro and pteron, which mean water and wing respectively. In January 2012, DCNS, a French naval defence company and one of Europe’s leading shipbuilders, became the ship’s sponsor and consequently her name was changed to l’Hydroptère DCNS.

In August 2012, the sailboat arrived in San Francisco Bay to participate in America’s Cup World Series race.

History of l’Hydroptère

The conceptualisation of l’Hydroptère dates back to 1975 when late Éric Tabarly (July 1931 – June 1998), a famous French yachtsman and an officer in the French navy, was told about viability of such a project.

In 1983, Alain Thébault took over the project. With Éric Tabarly’s guidance, he was able to build a model of the boat in 1985 and sailed it on the Grand Canal at the Château of Versailles, France. In 1992, Alain was able to get support from DCNS, Aérospatiale, Dassault and the Chantiers de l’Atlantique shipyard. They all decided to become a part of the project.

Construction of the boat commenced in 1993, with DCNS manufacturing the hull. It was completed in 1994 and in her maiden flight, l’Hydroptère was able to achieve a speed of 28kt.

The ship was taken out of action in 1998 after one of her hydrofoils was torn away. The incident occurred when she was trying to break the speed record for 24 hours. She returned to the water two years later after being fitted with a new hydrofoil. She was also armed with a 3D flight simulator.

Design of the experimental trimaran

The l’Hydroptère DCNS project was made possible by combining aeronautical and marine techniques. The three-hulled trimaran can fly five meters above the surface of water. In flight mode, the boat’s contact area with water is reduced to 2.5m 2 .

The boat’s take off is attained by her hydrofoils, which are fitted underneath each of the outrigger hulls. These are angled at 45° in water and give an upward thrust as soon as the boat reaches 10kt speed. The thrust that makes the ship to rise above the surface of water is produced due the difference in pressure between the upper and lower surfaces of the foil. The lift increases with the increase in speed. The ship can reach a speed of 45kt from 20kt in ten seconds.

The ship’s hydrofoils or wings are made of titanium coated carbon fibre to make them stand against powerful stresses. The boat’s optimised shape, which was attained by applying aerodynamic principles, ensures that she gets maximum efficiency from her sails and at the same time keeps the wind-resistance to a minimum.

Adastra is a trimaran-type superyacht built by McConaghy Boats for Hong Kong-based shipping baron Anto Marden. The 42.5m (140ft) superyacht has been designed by UK-based John Shuttleworth Yacht Designs.

The overall length of the boat is 22.48m. The beam is 24m and draft (while in water) is 3.5m. The ship’s draft is reduced to 2m while flying. The length of outrigger hulls is 6.7m, while the length of each hydrofoil is 5.7m. The boat’s weight is 7.5t.

The mast is 28m tall. Gennaker area and mainsail area of the sails are respectively 315m 2 and 185m 2 in size.

The trimaran requires about 12kt of stabilised speed to take off. Her speed is approximately two times that of wind; in other words the boat cruises at 30kt with 15kt of established speed. Maximum speed of the boat is 56kt and maximum average speed on one nautical mile is 50.17kt.

Contractors and suppliers involved in the hydrofoil trimaran project

Van Peteghem Lauriot-Prévost (VPLP), a French naval architectural company, and HDS were the main architects of l’Hydroptère DCNS.

The central hull of the boat was manufactured by DCNS Lorient, while floats and crossbeams were built by shipyards Decision and Airbus Nantes respectively. Foils and rudder were built by B & B and Airbus Nantes, and mast by Lorimat. Strain absorbers were provided by Legrand & Revigny.

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.

How fast do hydrofoil boats go?

Hydrofoil boats can reach impressive speeds, depending on their design and purpose. Racing hydrofoil yachts can achieve speeds over 50 knots (57.5 mph or 92.6 km/h), while recreational hydrofoil boats can reach speeds of 20-30 knots (23-34.5 mph or 37-55.5 km/h) or more.

Why don’t boats use hydrofoils?

While hydrofoils offer significant advantages in terms of speed and efficiency, they also come with certain limitations. The complex design and higher costs associated with hydrofoils can be prohibitive for some boat owners. Additionally, the handling and control of hydrofoil boats require a certain level of skill and experience, making them less accessible to novice sailors.

Airbus Joins Sailing Team

American Magic, the U.S. challenger for the 36th America’s Cup sailing competition, named Airbus its official innovation partner on Tuesday. Together, they will design, build and test a cutting-edge AC75 Class monohull sailboat in time for the Cup races in 2021. As shown in the AC75 concept video below, the 75-foot boat will incorporate hydrofoil technology, allowing its hull to lift fully out of the water and making Airbus’ aerodynamics expertise particularly useful.

“This is a true challenge for the team to see how they can optimize technological innovation under tight time and resource constraints,” said Airbus Executive Vice President Engineering Jean Brice Dumont. “We love good, clean competition. That’s what pushes us to continually improve at innovating, solve challenges, learn from experience and, ultimately, win.” According to Airbus, the company will provide engineering support for the project, including simulation capabilities development, systems architecture design and testing, hydrodynamic calculation and optimization, boat control and instrumentation.

Airbus also partnered with Oracle Team USA for the 35th America’s Cup, which was held in June 2017. Given shared and parallel technologies in sailing and flying, Airbus says the Oracle partnership resulted in an improved wingtip design for the A350 and instrumentation the company now uses on all aircraft development.

The America’s Cup was first awarded in 1851. The competition is considered one of sailing’s oldest and best-known racing events.

The Most Insane Yacht on Earth Just Got Even Insaner

As far as sporting trophies go, it's hard to find any older than the America's Cup . Sailing teams have been fighting over the ornate, sterling silver ewer since 1851. But while Queen Victoria would recognize "Auld Mug" today, she likely wouldn't even register the watercraft racing after it as boats.

These vessels are like luxury yachts the way Formula 1 cars are like family sedans: They drive, and the similarities stop there. The folks eager to win sailing's greatest prize sink fortunes on the latest modern technology and materials, yielding vessels that don't so much plow through the water as fly above it.

In February, America's Cup defending champion Oracle Team USA unveiled the boat it would take to the briny deep in 2017. It looks like two black and red missiles, bound together with a lattice of carbon fiber tubing, and towered over by a fabric sail---the only conventional element. If it seems ready to take flight, it might be because Oracle tapped aviation giant Airbus to fine tune the design.

This yacht, dubbed AC50, is in some ways a tamer version of the design that won the last America's Cup, but was criticized for being so powerful, even pro sailors had trouble handling it. In the 2013 races in San Francisco, several boats crashed; one sailor died . So this newcomer is 50 feet long instead of 72, and demands a crew of six, not 11. (Every competing yacht uses the same basic design, which the defending champion selects.)

Modern catamarans generate lift with a hydrofoil suspended under the hull. It boosts the boat out of the waves, like an underwater wing. Flying above the water for most of the race cuts drag and raises speeds.

But the heart of what makes these yachts so fierce has only been strengthened. America’s Cup Class catamarans use lift generated over a hydrofoil suspended under the hull---like a wing under water---to boost the boat up out of the waves and make it fly. Instead of pushing its hull through the water, the yacht skims the surface, riding on what look like little feet.

"You just have this little hokey stick foil section cutting through the water,” says Aaron Perry, Oracle Team USA designer, who has spent the last year and a half in Bermuda developing the new boat. Less drag equals more speed, which is why velocities have doubled since yachts started using hydrofoils. In 2013, Team Emirates topped 50 mph. Despite the smaller boats, this year’s racers are likely to go even faster.

There's not much room for creativity to make that happen. The 50-page design guidelines demand every boat be identical, save a few key elements, including the hydrofoil shape and control systems. So that's where Airbus engineers focused their aerodynamics expertise. "What is amazing for an aeronautical engineer like me is that the technology used to design these flying boats is very similar to the ones we’re using to develop and test aircraft,” says Pierre Marie Belleau, Airbus' head of business development and a keen sailor himself.

The planemaker even invited Oracle to experiment with its foils at its Hamburg testing facilities. They put them through some vibration, torsion, and bending tests, as well as a pressure test to breaking point---treatment usually reserved for commercial airliner wings.

The result? Where the old boat could only "fly" when going downwind, Oracle has nearly perfected how to rest on its foils no matter the conditions. "The boats are completing practice races without coming off the foils," Perry says. "The hulls are now almost irrelevant."

The defending champions, not wanting to leave anything to chance, also worked with BMW to integrate a steering system derived from touring car racing. Applying the semi-automated systems designed for automotive applications, the engineers made a yacht that responds to a turn of the wheel nearly instantaneously---instead of taking two seconds.

Even with all the technology and trials, on race day, it will come down to human factors. “It’s been a combination of getting time on the water, and really good crew work," says Perry. "To get around the racecourse without touching down off the foils requires a kind of a symphony." Everything has to happen with perfect timing, adjusting and trimming on the fly. The sailors still matter.

And they're in for a challenge. Oracle Team USA will face challenges from teams from the UK, France, Sweden, New Zealand, and Japan, vying for the chance to wrest the ancient trophy away when qualifiers start in May.

Sailing’s Hydrofoiling Revolution

• By Herb McCormick
• January 18, 2023

There’s a revolution underway in the sport of sailing, and it can be summed up in one simple word: foiling.

More specifically, we’re talking about hydrofoils , the winglike appendages mounted beneath the hull of a vessel that, at a certain speed, lift the hull clear of the water. When this happens, the foiling sailboats can reach speeds two or even three times faster than possible in “displacement” mode.

And sailboats are just one element of the foiling revolution: Surfboards, paddleboards and powerboats are also getting in on the act.

An Italian naval architect named Enrico Forlanini is credited with developing the first waterborne hydrofoils, which he affixed to a 60 hp, airscrew-driven craft that topped off at 36.9 knots back in 1906. In the century that followed, a series of would-be inventors took a swing at the concept with varying degrees of success. Foiling sailboats finally ascended into the mainstream during the 2013 America’s Cup, when Oracle Team USA beat Emirates Team New Zealand in a match between foiling 72-foot catamarans (the Cup has been contested in foiling cats ever since).

Surprisingly enough, my first foiling experience happened some three decades ago, aboard something called a Hobie TriFoiler, from the popular manufacturer of Hobie surfboards, beach cats and kayaks. The TriFoiler, basically a 22-foot trimaran with a central pod and a pair of mainsails stepped on the twin outriggers, was invented by a fanatical California engineer named Greg Ketterman. The sail controls were laid out just forward of the tiny airplane-style cockpit; you steered with foot pedals. It was so ridiculously easy that even a gremmie like me had the thing foiling within moments of getting in and reaching off.

But after the initial thrill, it was actually kind of boring. Which, I believe, is why it went out of production soon after. The TriFoiler was, unfortunately, way ahead of its time.

Such was the extent of my personal foiling experience until this past summer, when a new class of foiling monohull skiffs called Persico 69Fs rolled into my home waters for a series of races among youth squads in the class’s inaugural season. I got an invitation to take a spin.

After donning my helmet, wetsuit and life jacket, I was handed the helm with a pair of skilled young sailors on board. At 25 knots, we were towed into Narragansett Bay behind a powerful RIB, foiling all the way. It was terrifying. And a preview of coming attractions.

Once the tow dropped us, the sails went up and we bore off. I skied the tiller extension while scrambling out onto the hiking racks. Which sent us off on a screaming reach. Which flipped the 22-foot-7-inch carbon rocket ship.

Twenty seconds into foiling, and I’d capsized the bloody thing. How embarrassing.

The kids, bless them, were kind and patient. We got the whole shooting match, including ourselves, back upright and tried again. The mainsail trimmer sheeted it home, we started to accelerate, and he said: “Here we go! You’re up. You’re flying!” Indeed, we were.

Hard on the breeze in the 12-knot southwesterly, things unfolded quickly. Spray was flying, and I took more than one solid wave to the kisser. I was mostly too frightened to concentrate on anything but driving, but I did glance at the speedo once: 17.4 knots. (I felt pretty chuffed until later learning a 69F’s top speed is 34 knots. Ugh.)

However, I guess I’d proved the point: With a couple of sailors who know what they’re doing, foiling is for everyone. From now on, just call me Mr. Foiler.

‍ Discover the Magic of Hydrofoil Sailboats

Hydrofoils saw their early development as a concept for enhancing speed and efficiency on the water. From Alexander Graham Bell's experiments to the application of foils on sailboats in the 1950s, the quest has always been for greater speed.

But it wasn't until Russell Long championed these designs with the CEC foiling catamaran and the development of the Hobie Trifoiler that hydrofoils began to carve a distinct niche in the sailing world.

This sailboat operates on a simple yet ingenious principle: as the speed increases, the foils submerged beneath the boat generate lift. This lift thrusts the boat's hull above the water, dramatically reducing drag.

It’s similar to how air flows around the wing of an airplane, only with water's denser environment offering a different dynamic. This revolutionary foiling system allows boats to glide over waves, offering an incredibly smooth ride.

The variety of hydrofoil sailboats is astounding, from the foiling catamarans that have revolutionized the America's Cup to the twin sail trimaran designs. The fastest production sailboat, the Hobie Trifoiler , showcases what hydrofoils are capable of.

Additionally, boats like the innovative Emirates Team New Zealand vessels continue to push the boundaries of technology in competitive sailing. Whether for recreational purposes or high-speed racing, the range of hydrofoil sailboats caters to different sailing experiences and preferences.

Now, let’s explore the various aspects of hydrofoil sailboats that make them truly magical.

The Thrills of Hydrofoil Sailing

When I first stepped onto a hydrofoil sailboat, I knew that sailing would never be the same for me. Harnessing the power of the wind to achieve remarkable speeds while hovering above the water was nothing short of revolutionary.

It's an adrenaline-infused blend of sailing, flying, and innovation that promises high performance and stability with a significant reduction in wetted areas.

The allure of hydrofoiling is not just about the speed; it's the sensation of flying over the waves, defying the conventions of traditional sailing. With each gust, my hydrofoil sailboat becomes a silent, swift car, slicing through the air rather than merely sailing on the water.

When sailing with hydrofoils, you get to experience the following benefits.

• High Speed: With hydrofoils, I've seen and achieved speeds I never thought possible on water.
• Less Wetted Area: As the hydrofoils lift the hull out of the water, drag is reduced, further contributing to the craft's efficiency and speed.
• Stability: Surprisingly, the flying sensation is accompanied by stability once airborne, making the ride smoother.

The America’s Cup Competitive Foiling

Over the years, I've witnessed first-hand how hydrofoil technology has radically altered the landscape of competitive sailing. The introduction of hydrofoils has not only redefined what we consider possible in the sail area but has also brought a fresh surge of excitement to the racing circuit.

The most illustrious event in sailing, the America's Cup , underwent a transformation with the embrace of hydrofoils. Emirates Team New Zealand, a frontrunner in hydrofoil innovation, redefined the America's Cup racing in 2017.

Alongside them, the US team and Luna Rossa played pivotal roles in reshaping the landscape of America's Cup racing.

With their AC50 class catamarans soaring above the waves at top speeds that defy traditional sailing limits, they clinched the title and shifted the focus of competitive racing toward technological prowess.

The spectacle of these vessels racing is not just about the crew's capabilities but equally a testament to engineering marvels.

Also, the advent of hydrofoils in racing has certainly led to a spike in performance metrics. Here's a concise table highlighting the before and after impact of hydrofoiling in competitive Sailing:

This table illustrates just how much the racing landscape has shifted; it's not only sailing anymore.

It’s similar to piloting a high-speed aircraft, with each crew member playing a crucial role in harnessing the raw power of the strong winds in harmony with state-of-the-art technology. Watch this video for a more detailed explanation of hydrofoil sailboats and their magical power.

Technical Aspects of Hydrofoil Sailboats

In diving into the technical aspects of hydrofoil sailboats, I'll give you an insight into the intricate designs that enable these marvels to glide above the water, as well as the cutting-edge foil technology propelling them.

The design of a hydrofoil sailboat revolves around its capability to elevate the hull above the water, reducing drag and enabling high wind-speed travel. Control mechanisms are central in maintaining stability, especially when the sailboat interacts with varying wind conditions or maneuvers through shallow waters.

The hull's length and overall design are calibrated for balancing aerodynamics with hydrodynamics. In designing sails and hulls for foiling, one must carefully balance the need for power with the propensity for lift.

The sails are tailored not only to harness the wind's energy effectively but also to match the unique mechanics of a vessel in flight. Meticulous engineering ensures that the sail configuration works in harmony with the foils to propel the sailboat forward swiftly.

Additionally, the foil technology, which is pivotal to modern hydrofoils, has undergone significant further development over the years . From the materials used to the manufacturing processes, every element incorporates the latest in technology to yield extreme performance.

Advancements have led to foils that can automatically adjust to sailing conditions and speed, which is instrumental for achieving and maintaining high speeds.

Currently, the future of hydrofoil technology seems bound for even further breakthroughs. Customization and refinement of foils for specific water conditions, such as the challenges posed by shallow water, are ongoing.

Each new iteration builds upon the last, consistently advancing the field and informing the next leap in hydrofoil sailing. This persistent innovation in foil and hull technology is a testament to the potential that lies ahead for hydrofoil sailboats.

Are Hydrofoil Sailboats the Right Options for You?

Hydrofoil sailboats offer a unique and thrilling sailing experience, but whether they are the right option depends on your preferences and goals. These high-performance vessels are known for their exceptional speed and stability, making them ideal for thrill-seekers and competitive sailors.

If you're passionate about cutting-edge technology and want to push the boundaries of traditional sailing, hydrofoil sailboats could be a perfect fit.

However, they may require a learning curve for beginners and are typically more expensive than traditional sailboats.

Consider your skill level, budget, and desire for speed and innovation when deciding if hydrofoil sailboats align with your sailing aspirations.

The Future of Hydrofoil Sailboats and Their Transformative Potential

Over the years, I've been captivated by the evolution of sailing and the recent advancements in hydrofoil technology, which promise a thrilling future for these marine crafts.

The technology supporting hydrofoil sailboats is rapidly advancing, bringing us closer to a world where boats gliding above the water's surface is a common sight.

These boats use 'wings' or foils submerged in water to lift the hull above the surface, reducing drag and allowing for greater speeds. This innovation is not just limited to racing but is expected to influence recreational and transport vessels in the future.

Today, we see hydrofoils in action with hydrofoil kiteboards, which have become popular among thrill-seekers. This is due to their ability to harness wind power and achieve impressive acceleration and agility on the water. This same principle is being applied to larger sailing vessels, where performance and sustainability converge.

The further development of hydrofoil technology involves intensive research into materials and design optimizations that can handle the challenges of varied sea conditions.

Electric and solar-powered hydrofoils are on the horizon, poised to significantly impact our world by offering greener alternatives to traditional boats.

THE TECHNOLOGY

Although foiling feels like a recent revolution to take the world of watersports by storm, it has been at the heart of America’s Cup racing for 10 years. It was August 2012 when the sailing world was turned upside down by a 72- foot catamaran flying in the Hauraki Gulf. Emirates Team New Zealand had brought foils to the America's Cup, changing the face of top-level yacht racing forever. Six years later, in 2018, the publication of the AC75 Class Rule marked the beginning of a new sailing era. The engineering and sailing techniques needed to get the AC75 to fly were completely different from anything seen before. During the 36th America's Cup in 2021 the AC75 proved themselves to be unique and kept millions of fans worldwide glued to their screens.

Therefore On the 15th of November 2021, eight months after Emirates Team New Zealand successfully defended the America's Cup, an updated 'Version 2' of the AC75 Class Rule was released. The foiling monohulls to be used in Barcelona in 2024, will be slightly different, with rules being tweaked partly to improve light wind performance and reduce crew numbers from 11 to 8. The move to reduce the crew means cycle power is again legalised, and the cyclors, introduced by Team New Zealand in 2017, might return in the game. But what's the technology behind the AC75?

Therefore On the 15th of November 2021, eight months after Emirates Team New Zealand successfully defended the America's Cup, an updated 'Version 2' of the AC75 Class Rule was released.

The move to reduce the crew means cycle power is again legalised, and the cyclors, introduced by Team New Zealand in 2017, might return in the game. But what's the technology behind the AC75? To start with, the AC75 is big - 75-feet long and 16-feet wide - but, it's also light, which is crucial, because the AC75 is designed to fly. It's also different - rather than a keel, a brand new concept keeps it standing. Foil Cant Arms move under, or outside, the boat to provide the leverage it needs to stay upright. Some parts of the boat are supplied - the mast, rigging, foil-cant arms and their hydraulics are all stock components. But, there are still plenty of areas that designers can experiment with to find a race-winning edge. The double-sail skin Mainsail combines with the D shaped mast to form a wing, generating the power the AC75 needs to foil. Underwater is where things get really interesting, the foil cant system is a battery-driven, hydraulic power-unit that supplies the energy to lift and lower the immensely strong - and heavy - foil cant arms. As the boat swaps tacks, the cant system is activated, placing one hydrofoil in the water, and lifting the other one out, where its weight becomes ballast. At the end of the arms lie the teams' secret weapons - the foil wings. Apart from basic rules governing dimensions and weight, these are open territory for designers. With the teams allowed to build only one AC75, will a lot change from what we have seen during the last Cup, or will the new monohulls resemble the winning Kiwi boat?

The $10 Million Boat That Will Win the America’s Cup

The five things you should know about the tech competing in this great, intense sailing race

Heading out the door? Read this article on the Outside app available now on iOS devices for members! >","name":"in-content-cta","type":"link"}}'>Download the app .

Think of the America’s Cup as the Indy 500 on water. Yes, it’s a boat race, but calling these things “boats” is like calling Elon Musk’s Hyperloop a choo-choo train. These are some of most advanced racing vessels on earth, capable of speeds in excess of 55 miles per hour. In fact, thanks to the technology that lifts the boats above the surface of the water (more on that later), they can actually travel faster than the wind. With another race in the lead-up series happening on June 11-12 in Chicago , and the main event set for next summer in Bermuda , now is the perfect time to get up to speed. Here’s what you need to know about the technology used to compete in the greatest show on two hulls.

I’m Guessing It’s Expensive to Race?

In a word: Yes. The boats alone cost between $8 million to $10 million, and most teams have a backup just in case. However, the boats are only part of the story, because you also have to take into account the entry fee ($3 million), the staff (Oracle Team USA had 130 people in 2013), the cost of shipping all that sailing equipment around the world, plus costs of maintenance, operations, and incidentals. It has been estimated that mounting a successful America’s Cup campaign costs over $100 million. Larry Ellison may have spent $250 million to $300 million defending the title in 2013.

That said, organizers are attempting to reduce costs. For 2017, competitors will race a smaller class of boat called the AC45, which is 45 feet long, rather than the AC62, which is 62 feet long. (Boat size had been previously reduced in 2013 from 72 feet to 62 feet.) Typically, smaller boats can be developed faster, require smaller crews, and cost less to transport.

How Do They Get the Boats from Race to Race?

At one point you had to sail your competition boat to the race, but today’s vessels just aren’t made for that kind of mileage. Teams typically disassemble them, package them up, and ship them on larger boats or planes to the tune of hundreds of thousands of dollars in transport and insurance fees.

How High-Tech Are These Boats?

Each team designs and develops its own boat and tries to keep the proprietary technology secret from other teams (despite the best efforts at spying when competitors are practicing on open water). What we do know is that everyone will be racing a twin-hulled catamaran that uses a hydrofoil to lift itself out of the water at speed. Of course, there are hundreds of nerdy boat rules that teams have to follow, but specifics around materials and drag-reducing technologies to provide an edge are kept under wraps. Various teams partner with aerospace companies like Red Bull Advanced Technologies, Airbus, and Cosworth to develop the technology.

What Makes the Boats Unique?

For starters, the hulls are made of honeycombed aluminum (so they’re light as can be) and the fixed-wing sail is made of Kevlar and carbon fiber instead of a flappy fabric sheet. But the biggest difference is in how they move. Where a traditional boat muscles through water or skips across the surface, an America’s Cup boat barely even touches it. This is made possible by L-shaped hydrofoils or “daggerboards” that lift the hull completely out of the water at speed. Since the introduction of hydrofoil technologies, race speeds have literally doubled.

What Other Technologies Do the Teams Use?

In 2013, the name of the game was live performance data. According to Forbes , Team Oracle USA’s winning boat had over 300 sensors analyzing 3000 variables ten times per second—things like mast strain and sail effectiveness. Meanwhile, video feeds monitored every detail and course adjustment. This boat collected 200 gigabytes of data per day. Just imagine how far these kinds of data collection methods have advanced in the four years since the last America’s Cup. (To put things in perspective: during the last event you were likely rocking an iPhone 4 or 4S, maybe the 5 if you were an early adopter.)

iFLY15 – Technical SPECS

Length 4.63 m, 15 ft..

A Foiling Catamaran for 1-2 person(s) does not need to be any longer than this. The ancient rule that says you need length to achieve speed does not apply, as hulls do not touch the water at most times.

Width 2.50 m.

This width provides plenty of righting moment, still being road legal ato be transported in horizontal position without disassembly.

7.5 m mast / 11.2 sqm mainsail

7.5 m mast with 11.2 sqm deck-sweeper mainsail. – 8.5 m mast on iFLY RAZZOR Pro with bigger rig

Draft: 95 cm

Innovations and more   >>>

In the hand of the experienced sailor, iFLY15 is a high-performance racing machine. STABILITY IS NOT CONTRADICTORY TO HIGH PERFORMANCE OR SPORTINESS , on the contrary, it is a prerequisite for safe reaching and maintaining constant high speeds. Stable flight allows the sailor to concentrate on the course, on the wind, as well as on opponents and strategy – rather than permanently getting distracted by working on the foiling balance.

EARLY TAKE OFF IN WINDS AS LOW AS 2Bft. / 6 KNOTS , by combining the innovative “KickOff” foil control with a trampoline that provides boost and with the latest generation of rig and foils.

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.

« INTERNATIONAL FORMULA 15 FOIL » Class Association. The new development class for FOILING, SINGLE HANDED on MULTIHULLS. Multi manufacturer class in the tradition of a Formula18, A-Class or international Moth. Enables large regatta fields and evolution of the boats, following the technical progress (which is especially essential in the case in Foiling). Strict regulations to avoid uncontrolled exaggerated development.

Airbus commissions three wind-powered ships to sail the Atlantic

To move parts while making less co 2 , so it can build more planes that make plenty.

Airbus has decided to commission three ships powered, in part, by the wind.…

The plane-maker on Thursday revealed it has “commissioned shipowner Louis Dreyfus Armateurs to build, own and operate these new, highly efficient vessels that will enter into service from 2026.”

The ships will have conventional engines that run on maritime diesel oil and e-methanol, the latter fuel made with a process that produces less CO2 than other efforts. Many ships run on heavy fuel oil, the gloopiest, dirtiest, and cheapest of the fuel oils. Airbus has therefore gone out of its way with the choice of diesel and e-methanol.

The ships will also feature half a dozen Flettner rotors, rotating cylinders that produce the Magnus effect – a phenomenon that produces lift thanks to pressure differences on either side of a rotating object. The rotors were invented over a century ago and are generating renewed interest as they reduce ships’ fuel requirements.

Here’s what they’ll look like on Airbus’s boats.

Airbus expects its three vessels to enter service from 2026 and has calculated they will reduce its average annual transatlantic CO2 emissions from 68,000 to 33,000 tonnes by 2030. However, the ships will also help the planemaker to increase the number of A320 aircraft it makes to 75 per month, and each of those craft will make plenty of CO2.

The craft will have capacity to move around seventy 40-foot containers and six single-aisle aircraft sub assembly sets - wings, fuselage, engine pylons, horizontal and vertical tail planes. Airbus’s current ships can only move three or four of those sets.

The ships will most often travel from Saint-Nazaire, France, to an A320 assembly line in Mobile, Alabama.

Airbus also operates custom planes to move its parts. The company’s Beluga features an expanded and bulbous fuselage and lowered nose. The planemaker made a fleet of Belugas based on its venerable A300 but has since planned replacements that use the A330 as a template. ®

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.

The foiling Candela C-8 is the first boat to use Candela’s proprietary C-POD, but bigger craft will follow later

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.

The electric Iguana is capable of three knots on the land and 30 knots at sea

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…

The foils lift up at slow speeds to reduce the draft

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.

It doesn’t end here, with fascinating one-off projects from Spirit Yachts and BMW on the water, it’s clear that foiling has a huge potential for transforming the world of boating.

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!

FLY WITH THE UFO

• Designed and built in the USA
• $11,500 USD
• Compatible and rewarding to all skill levels
• Lightweight for easy maneuverability
• Solid, nearly dent-proof, hull
• Unique patented hull and rig designs
• Stable on and above the water
• Small footprint for carefree storage and shipping
• Takeoff from about 8knts of wind
• Fast, fun, easy to control foiling

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.

Electric boats

Candela raises record funding to solve the biggest problem with electric boats.

The innovative Swedish electric boat maker Candela has just announced its biggest funding round ever, reeling in €24.5M (US $26.6M). Fresh off the announcement of the first commercial user of the company’s new P-12 electric ferry , Candela is now flying closer to its goal of replacing combustion engine watercraft with efficient electric boats in both the recreational and commercial boating industries.

The company is well on its way to achieving that goal, using an innovative design with computer-controlled hydrofoils that help its boats fly above the surface of the water. The hydrofoils enable the boats to use 80% less energy than comparable vessels covering the same route.

That efficiency improvement is an even bigger achievement in the water than on land, since electric cars only have to consider aerodynamics when they push air out of the way. Boats dealing with the hydrodynamic issues of much heavier water result in significantly lower efficiencies. Electric boats thus typically require incredibly powerful motors and massive battery banks. But Candela’s high-tech hydrofoils mean the boats can be much more efficient and economical with smaller motors and batteries that still achieve longer range.

And major boatbuilders seem to agree with Candela’s approach. In fact, one of the key contributing members of Candela’s latest record funding round is Groupe Beneteau, a leading global boat maker with a turnover of €1.46B, 15 factories, 9 brands, and more than 8,000 yachts built annually.

As the company explained, the move correlates with its own goals.

“Our investment perfectly aligns with Groupe Beneteau‘s ecological transition objectives, scaling up innovative solutions for more sustainable boating and unparalleled navigation experiences. Candela’s technology, enabling significantly more efficient electric vessels, will transform waterborne transport into its next sustainable phase”, said Bruno Thivoyon, CEO at Groupe Beneteau.

It’s a major score for Candela, as the company’s CEO Gustav Hasselskog added:

“We couldn’t be more excited about having Groupe Beneteau on board. As the leading global boat company, their trust is a stamp of approval for our technology to transform waterborne transportation. We’re excited for the possibilities ahead.”

Candela expects the new investment round to help scale up production to meet demand for the recently launched Candela P-12, the world’s first electric hydrofoil ferry.

The P-12 marks a new chapter in waterborne transport, as it’s the first fast and long-range electric ferry on the market. Its efficient hydrofoil tech cuts lifetime emissions by an impressive 97.5% compared to diesel vessels, while simultaneously cutting operators’ costs in half.

Since it generates minimal wake, the P-12 has been granted exemptions from speed limits in many no-wake areas, such as on its maiden route in Stockholm, where in July it will begin cutting travel times in half compared to road transport and legacy diesel vessels.

The superyacht world is speculating that Mark Zuckerberg just bought this 118-meter boat

• The 118-meter superyacht Launchpad made her maiden voyage last week.
• The yacht world is speculating that her owner is Meta CEO Mark Zuckerberg.
• Here's what we know about the luxury vessel.

In the world of superyachts , privacy is the most valuable asset. It can be next to impossible to discern the details of a superyacht transaction — and that's particularly true if the vessel in question is worth nine figures.

Yet some in the boat blogging world are speculating that Meta CEO Mark Zuckerberg is the new owner of Launchpad, a megayacht currently moored in Fort Lauderdale, Florida after she made her maiden voyage from Gibraltar to St Maarten last week. Launchpad clocks in at 118 meters long, about nine meters shorter than Jeff Bezos' superyacht Koru .

The transaction could not be confirmed, with yacht world insiders declining to share what they know and representatives for Zuckerberg not responding to a request for comment from Business Insider. In the past, reports about Zuckerberg owning superyacht Ulysses have proven false.

"It is Feadship's standard policy to never divulge any information about our yachts with reference to ownership, costs, or delivery, etc," Feadship, the ship's builder, wrote to BI. "Whether it is an 18-meter Feadship from the 1960s or a 118-meter Feadship from the 21st century, we do not share private information."

But Zuckerberg's name has been connected to Launchpad for a few months now, beginning in December when reports swirled that he visited Feadship's shipyard in the Netherlands.

Then, earlier in March, yachting bloggers like eSysman SuperYachts and Autoevolution started speculating that he officially snagged the boat, originally built for a sanctioned Russian businessman, at a $300 million price tag. (While that's a seemingly huge amount, it's still less than 0.2% of Zuckerberg's $177 billion net worth.)

Another clue that might point to US ownership is that the yacht bears the flag of the Marshall Islands, a US territory and commonplace for American buyers to register their ships, according to public marine tracking.

If Zuckerberg were to have bought Launchpad, he would join a cohort of superyacht-owning tech billionaires . Along with Bezos, the likes of Oracle cofounder Larry Ellison and Google cofounders Sergey Brin and Larry Page have purchased impressive boats with even more impressive amenities.

SuperYacht Times , an industry publication and intelligence platform, has some of the best images of the yacht. Photos show a swimming pool on her main deck and a large helipad.

While less is known of the interior, a vessel of her size can likely sleep dozens of guests and crew and may have amenities like an expansive gym where Zuckerberg could practice his jiu-jitsu or a spa with a massage area. We suspect there's also space for plenty of toys — which could include his viral hydrofoil foil .
