An air-cushion vehicle of the type having a flat rigid platform with rigid longitudinal walls attached to the platform. In such an air-cushion vehicle a plurality of transverse trough-shaped skirts are provided so as to form a space bounded by the skirt and the platform which, when supplied with higher pressure air, serves to provide an air cushion chamber. The vertical height of the air cushion chamber can be varied in accordance with the present invention by extending or retracting the material of the trough-shaped skirts by way of an adjustment mechanism. In a preferred embodiment, the adjustment mechanism comprises a skirt bar attached to each of two longitudinal edges of the skirt and a mechanism for moving the skirt bars sideways closer together or further apart, thus varying the skirt\s vertical dimension.

In an air-cushion vehicle of the kind having a flat, rigid platform; a plurality of flat, rigid longitudinal walls attached substantially at right-angles thereto and depending therefrom substantially parallel with the major axis of said platform, an outermost two of said rigid walls being disposed as sidewalls along the respective outer edges of said platform; a plurality of longitudinally-spaced, laterally-aligned arrays of flexible trough-shaped skirts respectively looped with a space therein and fastened via each longitudinal edge thereof with respect to the underside of said platform; a source of pressurized air, said air being admissable, via apertures of fixed size at a relatively high pressure, to said skirts and also being admissable at a relatively lower pressure, via variable-sized openings, to at least four open-bottomed air-cushion chambers each bounded by an adjacent pair of said skirts and by an adjacent pair of said walls; a remotely-controllable adjustment mechanism capable of varying the vertical dimension of each said flexible trough-shaped skirt, said vertical dimension adjustment mechanism comprising a skirt bar attached to each longitudinal edge of said skirt and adapted to be slid sideways, in a skirt bar guide, in a direction parallel with the major axis of said vehicle so as to vary the fore-and-aft dimension of said skirt and thus the skirt\s vertical dimension.
