Abstract: An air cushion vehicle is provided with at least one stabilizing device comprising first and second members formed from endless bands of flexible impermeable material attached at first edges to the underside of the vehicle so as to extend downwardly therefrom and terminate at second edges. The first member surrounds the second member and is spaced therefrom so that in operation pressurized air from a source on the vehicle passes downwardly between the members to flow from between the second edges in the form of an air curtain which builds up and maintains a localized cushion of pressurized air within the stabilizing device.

Abstract: An air cushion vehicle has a flexible skirt assembly including an inflatable bag member. When inflated, the bag member is supported by a reticulated member, so that loads acting on the bag member are transferred to the reticulated member. Preferably a buffer material is interposed between the bag member and the reticulated member to prevent chafing of the bag member by the reticulated member.
