An air-cushion vehicle comprising a hull which is levitated above a pressure-receiving surface during operation by a cushion of pressurized air from an engine-driven propeller of the vehicle, said hull comprising a bottom hull wall and peripheral side hull walls extending around and connected to said bottom hull wall, said bottom hull and peripheral side hull walls forming an angle therebetween with said peripheral side hull walls being outermost and extending downwardly, a plurality of finger skirts attached to and extending around the periphery of the hull, each of said finger skirts comprising a plurality of connected walls forming a bag-like configuration, said finger skirt walls including an outermost finger skirt wall, two opposing side finger skirt walls and a top finger skirt wall, said outermost, side and top finger skirt walls closing the outermost, top and sides of each finger skirt and the bottom and innermost sides of each finger skirt being open, said outermost finger skirt wall having a bottom edge, said finger skirt when it is in a state of inflation by said pressurized air having said bottom edge open and shaped to extend substantially horizontally where said bottom edge is engageable with said pressure-receiving surface, and said top and innermost finger skirt walls extending closely adjacent said bottom hull and peripheral side hull walls of said hull.
