The heave stability of air cushion vehicles hovering over infinitely deep water is examined theoretically. When applied to the Canadian National Research Council craft, HEX-5, the theory predicts that the volume modulation produced by the spatially averaged deflection of the plenum water free surface would increase the stable operating region relative to overland operation. The air flow modulation produced by deflection of the water free surface at the lip of the plenum on the other hand would cause unstable behavior at low cushion pressures.
