ABSTRACT:
A hydrofoil craft, particularly a method of economically modifying a conventional hull with cambered foils to obtain and calculate increased lift from dense spray and to achieve enhanced craft performance is disclosed. The present invention improves speed, fuel efficiency and rough water stability, reduced pitch and vertical accelerations. A catamaran or V-bottom hull is modified with chine mounted aerofoils, flexible dihedral cambered foils positioned beneath the water line and on either side of the bow so as to create turbulence in the forward end of a tunnel(s). Tunnels are created on the V-bottom hull by the chine mounted aerofoils. Fixed forward tunnel cambered foil(s) and/or fixed or adjustable center tunnel cambered foils at the stern end of the tunnel to generate lift from pressure caused by dense spray in the tunnel(s) may also be provided. Adjustable cambered stern foils are mounted on the transom end of the tunnels.
