The DNA F4 is an exciting carbon 46-foot foiling One Design catamaran designed and built to push the boundaries of long-distance racing.

The boat is the result of an extensive design collaboration between DNA’s engineers and America’s Cup winner Shannon Falcone. The platform was validated from the fall of 2016 until the late spring of 2017 to have all items signed off for One Design approval. America’s Cup Team Oracle USA skipper Jimmy Spithill foiled the first F4 with a small crew from NYC to Bermuda, for a documentary titled Flying on Water.

The DNA F4 exceeds the speeds of much larger mono-hulls whilst providing the safety and comfort of a similarly sized cockpit. More importantly, racing an F4 requires a fraction of the crew needed to competitively operate a comparable mono-hull, substantially lowering the cost of ownership.

  • Dihedral hydrofoils ensure stable foiling while reaching speeds in excess of 35 knots
  • State-of-the-art carbon prepreg & nomex construction
  • Racing-focused cockpit layout
  • Low-drag aero profile

Each yacht is hand built in The Netherlands, bespoke and built to the highest industry standards by a small team of craftsmen.

The F4 is a one-design racing boat, meticulously hand-built in The Netherlands.

Shannon Falcone and Thomas Loughborough have set out to create a unique owner-driver class with the F4 as the class boat; the class has been named Tour De Foil and its website has launched at www.tourdefoil.com.

The first F4 has featured in two documentaries. Red Bull created the mission ‘Flying on Water’ with sailing legend Jimmy Spithill as offshore foiling skipper from New York City to Bermuda, for more information please visit Red Bulls microsite. A longer, 45-minute edit, of this cool trip aired at Outside TV in the US however is regrefully not available online.

When the F4 got into Antigua, Shannon reached out to his friend and snowboarding superstar Travis Rice to join them on their second offshore foiling trip from Bermuda to Antigua. Another, and really cool, documentary of this trip can be seen here. Recommended!

The goal is to offer speeds normally associated with maxis – for a lesser budget. Performance should be impressive at the least however we will hold off making any claims until we can validate more our ambitions with the sea trials.
