摘要： A surface-effect vessel including a central hull (2) and two thin side keels (3a, 3b) located on either side of the central hull and defining therewith, under the deadworks of the vessel (4), an air tunnel (12a, 12b) with an open side facing the water surface and front and rear transverse sides sealed by flexible front and rear skirts (5a, 5b, 6a, 6b), as well as blowers combined with respective air tunnels for blowing air into the space between the front and rear skirts to create two separate compressed air masses (8a, 8b) that each exert a lift force on the vessel. The lower edge (10) of each keel is shaped so that it partially emerges from the water when the vessel begins to roll (O) in the keel raising direction, whereby air leaks out sideways (D) and, the greater the degree of roll, the greater will be the corresponding reduction in the lifting force exerted by the compressed air mass laterally defined by said keel, and the faster it will occur. The rolling motion of the vessel is thus damped.
