Abstract
There is disclosed an improved air cushion seal system of the inflatable lobe type such as for operating between the sidehulls of a surface effect ship (SES), wherein in accordance with the invention at least the lowermost lobe of the system is partially closed at each of its opposite ends by a fabric sheet which is inset from the ship sidehulls. These substantially impervious to air passage sheets are affixed to the side edges of the lower loop of the lobe and up and around its aft end, and optionally to the upper loop of the lobe, to minimize scooping and water filling of the lobe, and to operationally stabilize the lobe.
