ABSTRACT:
A hydrofoil for watercraft is provided. The hydrofoil includes a generally flat body including an upwardly extending wing for providing low speed torque control and rudders extending from the bottom surface of the body to provide high speed torque control. The hydrofoil is adapted for mounting to an anti-cavitation plate. The depth of the hydrofoil can be controlled through the use of shims or a bracket including an offset arm to which the hydrofoil is mounted. The angular position of the hydrofoil is adjustable in the horizontal plane, thereby allowing the rudders to compensate for the lateral torque produced by a propeller.
