SIT&FLY

you can  fly

THAT FLIES ALONE

Extended version on your desktop computer

A foiler designed for any sailor.

The idea was to create a SIT & FLY foiler, that is to say a boat with foils that practically flew alone, and endow it with an exceptional stability so that any sailor could fly easily, regardless of their physical or technical preparation, also allowing them to access into the competition with foils so far suitable for only a few specialists.

The mothquito foiling catamaran perfectly meets this objective. proof of this is that none of our riders had ever flown on a boat with foils before and as you will see in the videos they all fly without any difficulty. , i sincerely believe that it is the best guarantee that the mothquito is made for you., you will soon be able to try it for yourself. happy flight.

Designer and CEO:

IFS Foiling & MOTHQUITO

THE BOAT THAT FLIES ALONE

The Mothquito Foiling Catamaran is the first foiler in the world with an increased dynamic stability and performance, by the IFS system, a system that increases its dynamic length and beam to make foiling easy, safe and fun for any sailor.

Due to this system, the Mothquito surprises with its great stability, both at take-off and during flight, requiring the crew member simply the same physical effort that would be required to sail in any conventional dinghy boat without trapeze and without the need for a special technique.  

In the Mothquito you just have to sit down to sail and the boat will practically will flies alone.

For all these reasons, the Mothquito is an easy and suitable foiler for all types of sailors, a true SIT & FLY.

At the same time, it can be a fundamental tool for schools and training centers, which are increasingly in demand for easy-to-fly, stable, yet fast and fun foilers.

But make no mistake, the Mothquito is more than just a docile and stable foiler. The Mothquito is a high performance catamaran racer. With a dynamic beam in flight of 4.8 m2, this boat manages to significantly increase its righting moment, which allows it to have a sail area of ​​17.5 m2 in its basic configuration, to launch the boat at high speeds without heeling or feeling of risk.

With mothquito you don`t need:.

Previous experience.

Specific technical training.

Special physical preparation.

Navigate against heeling as in the Moth.

Hang on a trapeze compromising your safety.

Height sensors and flaps to regulate the flight height, since its V foils automatically regulate the height.

Increasing the dynamic length:

You increase longitudinal stability, improving dynamic longitudinal trim in flight and reducing the risk of nose dive and pitch poles., increasing the dynamic beam:, increased transverse stability is achieved, increasing righting moment and performance, with a significant reduction in heeling., that is why mothquito marks a before and after, a new concept in the world of foiling which is summarized in a single expression:, sit & fly.

With Mothquito you know how.

BACKGROUNDS

As foiling progresses, more and more fans and sailors want to experience the sensation of flying, even if only once.

But the reality is that many of them are in doubt as to whether they will be able to fly continuously and controlled, since flying these machines does not seem as easy as sitting down.

In many cases, it requires significant physical preparation and endurance to be able to keep the balance in flight based on counter-heeling, making counter balance and playing with the mainsail sheet hunting and molding to maintain balance and not repeatedly go overboard.

In other cases, as in the majority of catamarans, it will be necessary to hang on the trapezoid to reduce the heeling, and at high speeds the maneuvers are very fast and precise, so the risk in these circumstances does not It exactly coincides with the idea of ​​enjoy it.

In summary we can group the current foilers into 3 large groups:

They are small foilers, monohull or multihull, for a single handed and they have a central inverted T-foil and another inverted T-foil in rudder on the same line. When they are monohull, flying on these boats without falling into the water is not easy. You have to establish a continuous balance by flying against heeling and keep your balance playing with the main sheet, and your weight.

In the case of multihulls, the outer hulls act as a float to stop preventing the overturns, as the small lateral wheels do on a bicycle when the child learns. but this solution does not eliminate the difficulty of the flight and slows down the speed of the boat every time the float enters into the water. they also use flaps with mechanical height sensors to control the flight height, and therefore require care and maintenance., they are dinghy catamarans for single or double handed and have four inverted t-foils., with a dynamic beam of around 2.5 m, which usually coincides with their hull beam, these foilers are much more stable than the 2t foils, but in them the use of trapezoids is usually common to compensate the heeling, which not everyone likes and less at high speeds., they also use flaps with mechanical height sensors to control the flight height, and therefore require care and maintenance., 2j + 2t foils, they are high-performance catamarans, of greater length and for more than two or three crew. it is common to see them compete on international circuits. their main foils are in j, which is the same as an underwater v when the boat heels, so they regulate the flight height without the need for flaps. they are very technical boats that require a lot of training and good physical shape. in addition they are not affordable since their price is usually not within the reach of every pockets..

If you are a training center or sailing school...

We are developing a strategic plan for the commercialization and international expansion of the Mothquito that may interest you.

FAQs 35' IFC

35' Internal Foiling Catamaran (IFC) - Frequently Asked Questions

IFC is Insetta Boatwork's Internal Foiling System.

You can expect a significant increase in cruise speed; Improved handling and stability in rough conditions; Better acceleration; A boat that is less affected by increased payload; A 20-40% increase in fuel efficiency; and a 20-40% further cruise range! Additionally, the IFC technology will also provide a drier ride in choppy conditions and Provide for more responsiveness when turning at speed!

The system is a fixed setup, there is nothing to operate and there are zero moving parts.

The IFC Technology in effect smooths out rough seas by allowing the boat to run from wave crest to wave crest at a relatively smooth and stable attitude. The IFC System creates lift which help to in effect “Carry” the hull higher in the water. The system acts as a set of wings carrying the boat at speed, keeping the hull from having to follow each wave across its entire contour. In other words the surface of the waves have less effect on the hull as the IFC system is lifting the boat. Additionally, the aerodynamic lift created by the catamaran hulls creates even more lift at the bow of the boat, keeping the nose high and preventing the “slamming” or sneezing found in other catamaran hulls.

No, you don’t. The foils are flush mounted to the bottom of the keels of each sponson (as well as up in the tunnel.) At its centerline the main foil of the IFC system is only slightly lower than the keel line. The boat will easily load onto a standard catamaran trailer. There is no big contraption hanging way down under the boat.

Remember, the foils are INTERNAL to the tunnel. At its lowest point the main foil is only slightly lower than the hull and is higher than the props. Because of this the odds of striking the foils are extremely low. The boat is designed to be lifted by the foil. The structural integrity of the foil system is such that the weight of the boat could be supported many times over by the foil. As such, if you did somehow manage to strike the foil on something EXTREMELY SUBSTANTIAL, like a stone shoal, the likely outcome is that you may (in a very worst case scenario) bend or break a foil wing. If that were to happen, you could still operate the boat to port with the remaining foils. The IFC foils are made from a very high-grade stainless steel and designed to meet or exceed relevant guidelines for impact and strength.

As water travels through the tunnel and around the foil, a tremendous vortex is created. This force keeps most debris from being trapped in the tunnel or around the foil. Between the pressure of the air moving through the tunnel, and the vortex created in the water, the tunnel and foils will stay clean and clear.

The outboards of the 35 IFC are mounted on a slight outward angle to place the propellers properly to maximize the thrust and flow efficiency created as the water travels through the tunnel and around the foils. This mounting also helps the boat to lean into a corner, much like a monohull.

Firstly, we’d ask, “Why would you want to?” But the short answer is no. IFC is an integrated system that is integral to the design of the boat.

The short answer is that boats with technology similar to IFC have been in use for many years, but not in the recreational market. Commercial and Military applications are quite prevalent. The initial design of a hull and system like this is quite complex and can be cost prohibitive. We at Insetta feel the gains in efficiency, speed, range and ride quality far outweigh the initial design and build cost.

Upon deciding to build a foiling Cat, Insetta assembled a team of naval Architects and Marine Engineers to refine an existing and proven design. Using their own state of the art construction techniques, Insetta brought an application specific version to the Center Console fiberglass market.

The transducer location on the 35IFC is ideal. We install transducers before the lifting strake immediately after the flat section of the keel, resulting in very clean water flowing beneath the transducer for optimal function while the boat is on plane or lifted by the foils.

How Do Hydrofoil Catamarans Work? (The Science Behind It Explained)

Have you ever wondered what it would be like to fly on the water? Hydrofoil catamarans are designed to do just that, and many people are amazed by the experience of gliding across the water at speeds that are unheard of with traditional boats.

But what are hydrofoil catamarans, and how do they work? In this article, well explain the science behind these revolutionary boats and explore the advantages, design considerations, and safety precautions that come with them.

Well also look at some examples of hydrofoil catamarans to show you just how powerful and advanced they are.

So, if youve ever wanted to know how these boats work and what sets them apart, read on!

Table of Contents

Short Answer

Hydrofoil catamarans work by using foil-shaped wings that protrude from the bottom of the boat, below the water line.

The foils are designed to lift the vessel out of the water, reducing the surface area touching the water, and therefore reducing drag.

As the boat moves forward, the airflow on the foils generate lift, causing the boat to rise out of the water and glide along the surface.

The foils act as an air cushion, allowing the boat to travel at higher speeds than a regular catamaran.

What are Hydrofoil Catamarans?

Hydrofoil catamarans are a type of boat that use hydrofoils to lift the hull above the water.

This reduces drag, allowing for faster and smoother sailing than traditional boats.

Hydrofoils are wings that protrude from the hull of the boat and are designed to lift the boat out of the water.

This reduces the amount of water resistance and allows the boat to travel faster.

The hydrofoils are adjustable, allowing the boat to be tuned to the desired speed.

Hydrofoil catamarans offer an efficient and fast way to travel on the water, making them a popular choice for recreational and competitive sailing.

The hydrofoils work by creating lift as the boat moves through the water.

As the boat moves, the water flow pushes against the hydrofoils and creates a pressure differential.

This pressure differential creates lift, which lifts the boat out of the water and reduces drag.

The hydrofoils also reduce the amount of wave resistance, allowing the boat to glide through the water.

The hydrofoils can be adjusted to match the speed of the vessel, allowing the boat to be optimized for maximum performance.

The angle of attack of the hydrofoils is also adjustable, allowing the boat to be tuned to the desired speed.

The fins are designed to keep the boat stable and can be adjusted to match the speed of the vessel.

In conclusion, hydrofoil catamarans are a type of boat that uses hydrofoils to lift the hull above the water.

How Do Hydrofoils Work?

Hydrofoils are a type of boat that uses a set of wings or fins to lift the hull above the water.

The hydrofoils are attached to the hull and use the water pressure to propel the boat forward.

The wings of the hydrofoils are designed to reduce the amount of wave resistance, allowing the boat to glide through the water with greater efficiency.

The wings are usually made of lightweight materials such as carbon fiber or aluminum and are designed to produce lift when the boat is moving at a certain speed.

The wings can be adjusted to different angles, which can increase or decrease the lift.

When the boat is moving, the hydrofoils create a low-pressure zone underneath the boat.

This low-pressure zone reduces the amount of drag and improves the efficiency of the boat, allowing it to move faster and more smoothly.

The hydrofoils also help to reduce the amount of wave resistance, allowing the boat to glide through the water with less effort.

They are suitable for all kinds of sailing, from racing to cruising.

Hydrofoils can be adjusted to match the speed of the vessel, making them an excellent choice for those who want to sail faster.

Hydrofoils are also a great choice for those who want to reduce their environmental impact.

Hydrofoils reduce drag, which means that they require less fuel to move the boat, resulting in lower emissions.

Hydrofoils are a great way to reduce the environmental impact of sailing while simultaneously enjoying a faster and smoother ride.

Advantages of Hydrofoil Catamarans

Hydrofoil catamarans offer a unique and efficient way to travel on the water.

The hydrofoil design reduces drag, allowing the boat to glide through the water with greater speed and stability than traditional boats.

The hydrofoils are attached to the hull and use the water pressure to propel the boat forward, creating less wave resistance than a traditional boat.

This allows the boat to move faster and smoother, while using less fuel.

Additionally, the fins can be adjusted to match the speed of the vessel, making it easier to control.

The design of the hydrofoil catamaran also allows it to ride high above the water, reducing drag and contact with the water surface.

This allows for a smoother ride, allowing the boat to move faster with less fuel consumption, and less noise and vibration.

Additionally, the hull shape of the hydrofoil catamaran is designed to increase its stability and maneuverability, further reducing drag and allowing for a faster and smoother ride.

The combination of the reduced drag, increased stability, and smoother ride makes hydrofoil catamarans a popular choice for recreational and competitive sailing.

The ability to move quickly and efficiently makes them ideal for racing, and the increased stability and maneuverability makes them well-suited for recreational activities such as sightseeing or fishing.

Additionally, the reduced contact with the water surface can help to protect the hull from damage, making the boat more durable and longer-lasting.

Overall, hydrofoil catamarans offer an efficient and fast way to travel on the water, making them a popular choice for recreational and competitive sailing.

The combination of reduced drag, increased stability, and smoother ride makes them an ideal choice for anyone looking to get the most out of their time on the water.

Factors Affecting Hydrofoil Performance

The performance of a hydrofoil catamaran depends on a variety of factors, including the type of hydrofoil, the size and shape of the hull, and the speed and direction of the wind.

The hydrofoil itself is an important factor in determining the performance of a hydrofoil catamaran.

Different types of hydrofoils offer different levels of lift, drag, and stability, so its important to choose the right hydrofoil for the job.

The size and shape of the hull also affects the performance of the hydrofoil catamaran, as the hull is the part of the boat that provides the buoyancy and helps the boat to stay afloat.

The speed and direction of the wind also affects the performance of a hydrofoil catamaran, as a headwind or tailwind can cause the boat to be pushed or pulled in a certain direction.

Finally, the weight of the vessel also affects the performance of a hydrofoil catamaran, as a heavier boat will require more lift from the hydrofoil to remain afloat.

Design Considerations for Hydrofoil Catamarans

Hydrofoil catamarans are a special type of boat that use a unique design to offer efficient and fast travel on the water.

The key component of the design is the hydrofoil, which is a fin-like structure attached to the hull that uses the water pressure to push it forward.

This reduces drag and wave resistance, resulting in a smoother, faster sailing experience than traditional boats.

When designing a hydrofoil catamaran, there are a few important considerations that engineers must take into account.

The hydrofoils must be designed so that they can be adjusted to match the speed of the vessel, as well as provide stability and reduce wave resistance.

Additionally, they must be constructed from durable materials to ensure they can stand up to the elements and provide a reliable ride.

The shape of the hull also plays an important role in the performance of a hydrofoil catamaran.

A rounded hull is ideal for reducing drag, while a flat hull is better suited for stability.

As for the size of the hydrofoils, they should be big enough to lift the boat above the water, but not so large that they create too much drag.

Finally, the placement and size of the hydrofoils must be carefully calculated to ensure the boat can reach its maximum speed while remaining stable.

It is also important to consider the weight of the boat and its passengers when designing a hydrofoil catamaran, as this will affect the performance of the hydrofoils.

By taking all of these factors into consideration, engineers can design hydrofoil catamarans that are both fast and stable, providing an enjoyable and efficient ride.

Examples of Hydrofoil Catamarans

Hydrofoil catamarans come in a variety of shapes and sizes, making them suitable for a variety of applications.

Popular examples of hydrofoil catamarans include the America’s Cup boats, the A-class catamaran, as well as the Nacra and Tornado catamarans.

The America’s Cup boats are the fastest boats in the world and are designed to achieve speeds of up to 50 knots.

The A-class catamarans are lightweight and designed for racing, while the Nacra and Tornado catamarans are designed for recreational sailing.

Each of these boats use hydrofoils to reduce drag and improve performance.

In addition to recreational and competitive sailing, hydrofoil catamarans are also used for transportation.

The Sea Eagle is a high-speed ferry that uses hydrofoils to reduce drag and increase its top speed.

The ferry is capable of carrying up to 250 passengers and can reach speeds of up to 50 knots.

Other examples of hydrofoil catamarans include the hovercraft, which uses a combination of air and water pressure to lift the vessel above the water, and the AirFish, which uses a combination of air and water pressure to fly above the water.

Hydrofoil catamarans are an efficient and fast way to travel on the water, making them popular for recreational and competitive sailing, as well as for transportation applications.

The hydrofoils reduce drag and increase performance, allowing these boats to reach speeds of up to 50 knots.

The design of the hydrofoils can also be adjusted to match the speed of the vessel, allowing for a smoother and more efficient ride.

Safety Precautions for Hydrofoil Catamarans

Hydrofoil catamarans are a popular choice for recreational and competitive sailing due to their efficiency and speed.

However, these vessels require extra caution to ensure the safety of all passengers.

Before operating a hydrofoil catamaran, it is important to understand the safety precautions needed to ensure an enjoyable and safe experience.

First, always wear a personal floatation device (PFD) when operating a hydrofoil catamaran.

This will provide a layer of protection if you fall overboard.

Additionally, if the hull of the boat is lifted above the water, it is important to check the area for any debris or objects that may be submerged.

This could cause damage to the boat or injure passengers.

It is also important to check the weather conditions before going out on a hydrofoil catamaran.

Wind, waves, and storms can all be hazardous for these vessels.

They are not suitable for rough water and should be avoided during inclement weather.

Additionally, it is important to check the engine and fuel levels before embarking on any voyage.

Finally, it is important to understand the limitations of the hydrofoil catamaran.

These vessels are designed for speed and maneuverability, not stability.

They are not intended for large groups or for carrying heavy cargo.

The hydrofoil system can also be easily damaged by impacts with rocks and other objects so it is important to be aware of your surroundings and avoid any obstacles.

By taking the proper safety precautions, you can ensure an enjoyable and safe experience while operating a hydrofoil catamaran.

Always wear a PFD, check the weather conditions, and understand the limitations of the vessel before going out on the water.

With the proper preparation, you can enjoy the speed and efficiency of a hydrofoil catamaran for many years to come.

Final Thoughts

Hydrofoil catamarans are a unique type of boat that offers an efficient, fast, and smooth sailing experience.

The hydrofoils lift the hull out of the water, reducing drag and wave resistance, allowing the boat to glide through the water.

With the right design considerations and safety precautions, hydrofoil catamarans can be an enjoyable and safe way to travel on the water.

If youre looking for a fast and efficient way to get out on the water, hydrofoil catamarans may be the perfect option for you.

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.
