The DNA F4 is an exciting carbon 46-foot foiling catamaran designed and built to push the boundaries of long-distance offshore racing.
The boat is the result of an 8-month design collaboration between DNA’s engineers and America’s Cup winner Shannon Falcone. The platform will be validated from the fall of 2016 onwards and we expect to have all items signed off for One Design approval in the spring of 2017.

The F4 is a one-design racing boat, meticulously hand-built in The Netherlands. We will release more information in the next few months.
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 a provisional website has been launched at www.tourdefoil.com.
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.
Interested in the F4? Please fill in your contact details, make reference to the F4 and drop us a message, we will be happy to respond.
