A hydrofoil catamaran boat equipped with sail or power propulsion having mechanical type automatic heel, pitch and height control. The hydrofoil configuration has but one main load carrying foil located forward of the center of gravity necessitating two stabilizing hydrofoils at the stern which are differentially operated in angle of attack to provide heel control. Pitch control is attained by cooperative action of the main load carrying hydrofoil's automatic height control and the tracking capability of the stern stabilizing foils. All foils are retractable to facilitate beaching, trailering and storage. The configuration confines the main hydrofoil to the space between hulls thereby reducing normal hydrofoil configuration beam dimensions to more acceptable limits.
