Document Type and Number:
WIPO Patent Application WO/2022/229020
Kind Code:
A1
Abstract:
The invention relates to a hydrofoil (1) for a watercraft comprising a fuselage (2) and two wings (4, 5) arranged on either side of the fuselage (2) and intended to provide hydrodynamic lift to the hydrofoil (1) when it is in motion in the water. According to the invention, the two wings (4, 5) are rotatable with respect to the fuselage (2) between a deployed position when the hydrofoil (1) is stationary and a position retracted towards a rear portion (7) of the fuselage (2) by the water pressure exerted on the wings (4, 5) when the hydrofoil (1) is moving in the water.
