ABSTRACT:
A hydrofoil sailboat comprises forward and aft surface piercing hydrofoils and an asymmetrical wingsail. Both hydrofoils have an inverted arch configuration and have a cross-section which is approximately a circular segment. The wingsail has a reversible asymetry, is carried on a cantilevered rotatable mast and includes a sail sock that is highly tensioned between a single top frame member and a bisectional articulated bottom frame member, the asymmetry of the wingsail being defined by the relative position of the bottom frame member sections.
