Title: Suppressing ejection of water and other surface material from air cushion vehicles

Abstract: To reduce the amount of water or other surface material issuing at the periphery of an air cushion vehicle, a flexible barrier is suspended at the vehicle periphery lateral to the cushion containing means--usually a flexible skirt. The spray or other material is trapped between the vehicle periphery and the barrier, with water or other material dropping down and air venting through apertures at the top of the barrier. Weight can be added to the lower part of the barrier to assist in maintaining the barrier down.
