l’Hydroptère is a 60 foot sailboat, but when it’s moving it doesn’t spend much time in the water. Above 12 knots, it pops out of the water and rides on hydrofoils, which look and act like small airplane wings under water. When riding on it’s foils the Hydroptère has very little surface area in contact with the water (2 square meters) and therefore, very little drag.
