ABSTRACT:
A hydrofoil member for a sailboat of the type having a single hull with no fixed ballast includes an elongate arm portion which extends laterally outwardly away from the sailboat along a generally horizontal plane when in use. The arm portion has an upwardly-facing surface, a downwardly-facing surface, and an outer end portion which flares upwardly relative to the horizontal plane. The hydrofoil member further comprises a pontoon element mounted on the downwardly-facing surface of the arm portion at the outer end portion. The pontoon element is adapted to engage and displace water when in use for stabilizing the sailboat. The arm has is capable of being retracted to stow the hydrofoil member in a parallel position against the hull when not in use.
