ABSTRACT:
A passive roll stabilizer for a boat in which a freely movable weight is supported for movement athwartships at a substantial distance above the deck on a mast or other superstructure. The weight is freely movable along an axis substantially parallel to the deck between widely spaced limits. The limits are defined by energy dissipating stops, such as spring-loaded dash pots or self-restoring plastic foam material.
