TF10 trimaran gives foiling enthusiasts an exciting lift

NEWPORT, Rhode Island _ New York Yacht Club member Malcolm Gefter says if you don’t foil while sailing “you are not sailing in the modern world at the highest level.” The racing enthusiast is one of the first owners of the 10m (36ft.) TF10 trimaran, built by DNA Performance Sailing, part of composite engineer and manufacturer Holland Composites.

DNA conjured up the foiling TF10 trimaran in late 2015 to make America’s Cup-level sailing and technology available to everyday racers.

Mindful of spectacular foiling mishaps in recent years, it made safety and ease of operation “prime goals during development.” Example: DNA opted for a trimaran, not a catamaran, as the center hull provides great buoyancy and stability reducing the risk of ‘nose diving’ or ‘stuffing’ and pitchpoling.

The TF10 achieves a top speed of 30+ knots. By the end of 2018, DNA expects to have launched at least 6 that will all go to the US and Australia. The TF10 already has its own racing class, governed by 5 sailing friends from Newport, RI., keen to share “the most advanced sailing technology on the planet” with club racers, says DNA co-founder Sven Erik Janssen.

“We see a lot of market interest for a safe, fast foiling boat,” he adds. “The aim of the TF10 is to make foiling safer, more accessible.” He calls the TF10 as a “manageable speed machine that bridges the gap between monohull and multihull sailors and embraces both worlds.”

The electronics-packed TF10 is made of carbon and titanium. It has electronic rake control, a tack-and-gybe button and semi-rigid carbon trampolines. Four-point foiling (using Z-foils) eliminates the need to mechanically drive the boards up and down. Flight control comes from electronically adjusting the foils’ angle of attack.

The TF10 boasts a full carbon, Southern Spars rotating mast. Class rules stipulate One Design equipment to keep racing cost of racing “reasonable and approximately the same” for all entrants and “avoid an arms race for equipment, sails and crew. The boat was designed to be raced with relative ease . It has light sheet and steering loads and no heavy daggerboards moving up and down.

The boat was designed to be serially produced. DNA built high-quality molds for 100+ production units. DNA’s current model line-up of foiling boats includes also the 5.5m (18ft.) F1 A-class single-handed catamaran, the 12m. (40ft.) G4 and the 14m. (46ft.) F4 long-distance racer.
