ABSTRACT:
A multi-hull vessel includes at least a pair of substantially parallel interconnected hulls and the outermost hulls each include a mast for supporting a sail. When sailing close hauled the wind on the leeward sail produces a force having a component tending to lift the adjacent windward hull out of the water which is counterbalanced by a corresponding downward component of the force produced by the wind on the windward sail.
