Abstract
A vessel having adjustable hydrofoils. The vessel is preferably a multi-hull sailing vessel such as a catamaran or trimaran. The hydrofoils diverge upwardly and outwardly from a location below the waterline of the vessel and in the plane of the longitudinal axis of the vessel. The hydrofoils are pivotally mounted at the inner lower ends thereof to permit said hydrofoils to pivot forwardly and rearwardly to alter the angle of attack of said hydrofoils.
