Meet the new TF10 – three hulls bringing triple the fun. The TF10 is a foiling trimaran measuring 11 meters [36 ft] in overall length, designed by Morrelli and Melvin, and built and marketed by DNA.
The foiling TF10 trimaran is fun to sail with friends in, and to compete in. A well-mannered thoroughbred. And when you know your way around the racecourse in monohulls, then your skillset will allow to race the TF10 too; it is merely a different application of sailing skills. The TF10 embodies the race-proved qualities of performance, ‘sailability’, reliability and safety which we believe are all desirable to make the TF10 Foiling Trimaran a success as the next One Design boat for yachtclub racing – a boat enticing men and women, youth and adults.
The TF10 foiling trimaran has been designed to exceed ABS offshore racing yachts requirements and is constructed of pre-preg carbon fibre with a Nomex honeycomb core for a lightweight, yet safe and robust construction. The boat can be offered in strict One Design spec for competition purposes. It is designed to be raced by a competent crew of four or five sailors, in a relatively stable and safe mode over a wide range of wind speeds and sea states.
It can entertain and delight. We hope it fires your imaginations too and we ensure that the TF10 foiling multihull will deliver on the thrill of sailing; after the foiling revolution there is now evolution, and the TF10 is the first boat designed from scratch to introduce lessons learned; making foiling safer and more accessible for the everyday performance sailor. The TF10 is a foiling sailboat with good manners.
Easily transport the TF10 – retract the amas and trailer or ship your boat. The TF10 trimaran has been built with ease of competition in mind. You can arrive in Key West on your own trailer, or ship to Europe on a standard 40’ flat rack.
Open up new inland weekend cruising destinations with the ease of a boat ramp. No need to line up for a hoist, pay for a travel lift or register for a highway permit. The TF10 can be pulled with a standard HD pickup truck and can be launched from a ramp. The TF10 is simple to transport and set up, and can be stored indoors.
The TF10 trimaran is now available for deliveries in 2018 and onwards.

The TF10 was conceived towards the end of 2015. The overall concept was to build a foiling multihull that could act as an effective bridge between America’s Cup-level sailing and technology, and the more prevalent type of active racing sailors. The TF10 class association that conceived of the project, is a group of five sailing friends from the US East Coast (Newport, RI) who united to create what they felt might be needed to bring American yacht club racing more on par with America’s Cup developments from the last decade – and keeping the young guns hooked to the sport of sailing. When the founding members set out to create this boat, considerations of wind range and seastate led to the development of a trimaran rather than a catamaran. The center hull provides exceptional buoyancy and stability which reduces the risk of ‘nose diving’ or ‘stuffing’ and pitchpoling.
These gentlemen have united as the TF10 Class Association and with their wealth of experience in various one-design racing series and experienced flaws earlier, the ultimate goal is to now create a racing series as exciting, honest and fun as the boat itself is.
The boat was designed to be produced as a series, One Design build, with a worldwide active Class. As such, high quality moulds were built, capable of supporting >100 production units. DNA has ample experience in manufacturing advanced composite products per strict requirements and small tolerances, thus ensuring that boats in One Design spec will actually be the same.
The TF10 Class actively encourages young adults and women to join in for racing. As such, the TF10 has been designed to be raced with relative ease by having sound ergonomics, light sheet and steering loads, and the elimination of moving daggerboards up and down (heavy).
The 2018 TF10 Regatta calendar is yet to be released with marquee events planned: Summer Series on the Eastern Seaboard, winter Florida Championship, and a potential European Race Series.

The TF10 is a foiling trimaran. Foiling allows for high speeds, however achieving high top speeds has never been a goal during development. We sought for great performance which is accessible and safe, allowing for high averages.
We meet our performance target when amateur sailors can sail and fly this speed machine always feeling in control, comfortably doing close to 30 knots downwind. The max VMG may be greater however again; that is not the greatest goal.
The foil package consists of Z-boards that offer relative ride height stability by their inherent design, and are meant to be kept deployed during normal upwind and downwind sailing. The Z-boards thus eliminate the need for exceptional crew coordination or large power consumption during manoeuvres. This foil design has been successfully employed in other foiling multihulls – such as the A-cats or the Olympic foiling Nacra 17.
The rudders are fitted with elevators designed to provide lift, and to create righting moment. Foils can be inserted into the floats from above, thereby eliminating the need to launch the boat with a crane. It may also be launched from the road trailer on a normal boat ramp.
The daggerboards are fitted inside of shock absorbing casings in case of a collision, thereby reducing the risk of severe hull damage. The T-rudders will kick-up in the case of impact at higher speeds.
To safely sail and foil, the TF10 is equipped with electrically-powered rake control for the Z-boards and T-rudders. This system allows for similar foil trimming options (rake forward or aft) as the 2017 America’s Cup Class boats had – sophisticated tuning of foil settings while sailing for a higher pace around the course. Rake control is accomplished by electric actuators, commanded by ergonomic switches located at positions easily accessible by the crew.
The mast may be fitted with an inflatable buoyancy balon that prevents the boat from “turtling” following a capsize, improving safety, making recovery easier, and reducing the probability of damage.
As the speeds can be high, safety and comfort have been a big concern throughout the development of the TF10. The wave-piercing bows have a large volume for extra buoyancy. The rigid seating benches with back support provide a comfortable means of increasing righting moment as well as being a barrier to accidental man overboard possibilities in cases of sudden changes in heel or directionality during manoeuvres.
Safety is also ensured by sound ergonomics throughout. A raised wishbone boom reduces the risk of head injuries from boom collisions when seated in the cockpit. A well laid out deck plan reduces tripping hazards when crossing sides and the loads on sheets is kept low, so the boat can be enjoyed and pushed regardless of age or gender.
The TF10 is fitted with a deck mounted rotating, carbon fiber wing mast (with a regatta splice for ease of logistics) and a wishbone boom elevated above deck for safety (mast and boom are made by Southern Spars). The sailplan comprises a decksweeper design mainsail which is reefable (double), a reefable jib, and a furling gennaker.
To walk around safely, the areas between floats and centre hull feature a semi-rigid carbon deck. This also keeps the boat drier when sailing fast.
