ABSTRACT:
A multi-hull sailing vessel includes at least a pair of opposing hydrofoils that have their longitudinal axes inclined inwardly toward one another beneath the vessel at a fixed angle to the horizontal, each foil being independently rotatable whereby the angle of attack of each hydrofoil can be adjusted to assist in maintaining the vessel in an upright position. The rotation of the hydrofoils can be automatic to produce greater lift for the leeward hydrofoil to resist the tendency of the vessel to heel to leeward.
