Abstract: A fluid-cushion-supported pallet or water skate in which the cushion-fluid is generally defined by a multi-part or segmental, flexible skirt, in which the contiguous skirt members have their downwardly and inwardly extending lateral portions flanked by tie portions extending inwardly from the lateral portion toward the space occupied by the fluid-cushion, the contiguous tie portions are secured outwardly of the inner edges to restrict the escape of the cushioning fluid, and the segmental flexible skirt prevents sideways deflection of the skirt segments caused by relative movement between the device and surface over which the device operates.

Abstract: An air cushion vehicle capable of operation over land or water, which includes a hull carrying at least one air supply unit, an outer inflatable member connected to and extending around the entire perimeter of the hull, which supports a flexible skirt system which extends down from the inflatable member, which it is part of, and air under pressure is supplied by the air supply unit to the skirt system in a regulated manner, to provide a balanced cushion at the bow, sides and stern and to prevent decaying of the cushion and ploughing. Self contained ballast apparatus is provided to trim the vehicle.
