A passive stern seal for a plenum chamber of an air cushion marine vehicle comprising a front rectilinear planar seal member with an upward extending curvilinear rear tip, a plurality of front seal member supporting stay members adjacent to the underside of the planar seal, and pivotally attached to the vehicle at their forward surfaces, strut members pivotally attached and extending from the front planar seal member adjacent the curvilinear tip; a rear seal member extending from an attachment to the vehicle downward and to an attachment to the front planar seal member forward of the curvilinear tip, the free end of the strut members are attached to the upper surface of the rear seal member and a plurality of forming members are attached between the rear seal member and the vehicle. The forming members cooperate with pressure within the stern seal and form at least one transverse convolute in said rear seal member. Apertures are provided through the rear seal adjacent the strut attachment point to provide drainage for any water trapped within the stern seal.
