ABSTRACT:
A cushion containing seal particularly suited for use as the bow or stern seal on a large ocean-going sidewall air cushion vehicle or surface effect ship, comprises adjacent elongated stiff members arranged near to one of their ends for attachment to rigid structure of the vehicle so as to be deflectable for contour conformation. Escape of pressurized air from the cushion between adjacent elongated stiff members is substantially prevented by flexible impermeable members that permit the elongated members to deflect with respect to each other. The elongated stiff members may be manufactured from metal so as to be rigid.
