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.

A catamaran vessel incorporating spaced parallel twin hull members interconnected by struts, at least one pair of hydrofoils diverging upwardly from a location below said hull members and adjustable support means interconnecting said hull members and said hydrofoils, the lower end of each said hydrofoil being mounted for pivotal movement about a substantially vertical axis to permit forward and rearward movement of the hydrofoils about said substantially vertical pivotal axis and with respect to said hull members thereby to alter the angle of attack of said hydrofoils, and the upper outer ends of the hydrofoils being slidable on said struts and being selectively fixable at desired positions along the lengths thereof.
