A ship's hull is provided where a substantial portion of the ship's hull, above its waterline, is designed essentially as a section of an aerofoil of the NACA foil type which is symmetrical to the centre line (S) of the ship's hull and where the leading edge (3) of the aerofoil section (2) is facing in the direction of the front of the ship (1), in order, with relative wind, to generate an aerodynamic lift that produces propulsion for the ship (1) within an angular sector of the ship's (1) course or direction of propulsion, the aerodynamic lift being balanced out by a hydrodynamic lift generated below the waterline. Also provided is a ship (1) including the aforementioned ship's hull. |
