ABSTRACT:
A hydrofoil vessel in which the hydrofoils comprise pairs of rotary members which are inclined in a downwardly inboard direction from opposite sides of the hull or body portion of the vessel. The rotary members have foil-shaped peripheral portions extending into the water at an acute angle with respect to the water surface and are movable both axially and angularly to achieve optimum lift consistent with the vessel's speed.
