As along last decade, completely new wind boats like Americans Cup AC75 monohull vessels (*) are appearing, completely new concepts with an exceptional efficiency which allows to fly over the sea near to 100 Km/h, or even surpassing (∼104 Km) with a Windsurf (**).
(*) The newest American’s Cup AC75 are 75 feet (22.86m) keel-less yachts, which rise out of the water on hydrofoils and glide across the surface to reach speeds in excess of 50 knots (93 Km/h).
The Challenger yacht “Luna Rossa” had maxed out at 53,4 knots (99 Km/h), (…) and Team New Zealand’s “Te Rehutai” is rumoured to be even faster.
