Abstract
An improved seal design for a Surface Effect Ship, having an inflatable ir seal member, and outer seal member composed of a pliable sheet material scrollably affixed to the hull fore and aft of the inner seal member. The seal may be retracted for hullborne operation by deflating the inner seal member and scrolling the outer seal member tight to hull. The inner seal member has transverse webbing for stability. The outer seal member is periodically scrolled foreward to expose an unworn section to the water surface thereby reducing seal failure due to wear.
