ABSTRACT:
Mast is pivoted to sailboat hull and carries a counter-balance weight below the pivot. Wind pressure causes mast heeling with the counter-balance supplying the mast-righting force. Additionally, movable weights in the hull bottom are cable-connected to the mast so that, upon mast heeling with respect to the hull, the weights are moved upward and outward. The underwater structure of the sailboat is also controlled by mast listing or heeling. When centerboard-equipped, the centerboard is lowered with mast heeling. When keel-equipped, the pivoted keel is swung for maximum stability.
