Abstract : The patent relates to a method whereby a captured air bubble vehicle is provided with fluid-biased fore and aft semi-flexible seals, each comprised of an upper, relatively rigid panel movable about a transverse axis and a lower relatively flexible panel attached to the upper panel for low drag local compliance with minor surface waves. The local compliance of the lower panel improves roll, heave, yaw and pitch stability of the craft. The co-action of the panels reduces chance of sudden venting of the craft supporting bubble.
