Next year’s America’s Cup in Bermuda may feature boats whose hulls never touch the water once airborne on their hydrofoils

Advances in foil design and foiling techniques make it possible for crews to tack while riding high. According to Glenn Ashby of Team New Zealand, design and control of daggerboards will ensure stability during upwind runs. Foil shape has changed since the 2013 Cup on San Francisco Bay. Today’s L-shaped models are designed taking into account cavitation, a function of section shape and speed. While foiling requires strengthening certain components, Ashby maintains that boats are safer with foils than without.
