ABSTRACT:
A seagoing vessel is stabilized by a passive system including tanks symmetrically disposed on the vessel below the water line. The tanks are connected by a conduit and pressurized with air to a selected pressure level. During each oscillatory roll and/or pitch cycle of the vessel, the tanks alternately fill and drain with selected volumes of water to reduce the righting moment of the vessel. The period of oscillation of the vessel is thus lengthened beyond the period of wave motion.
