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.
A sailing vessel including at least a pair of opposing hydrofoils having their longitudinal axes inclined inwardly toward one another beneath the vessel at a fixed angle to the horizontal, each hydrofoil being freely rotatable through a predetermined angle about an axis parallel to, but offset from, its longitudinal axis such that the angle of attack of each hydrofoil varies independently according to the forces acting on the hydrofoils when the vessel is sailing, the offset axis of each hydrofoil being positioned aft of the longitudinal axis such that t...
