Surface Effect Ship (SES) which has both an air cushion, like a hovercraft, and twin hulls like a catamaran
The vessel’s great performances are made possible by the ship type: Surface Effect Ship (SES), also known as air cushioned catamaran or side hulled hovercraft. She has two side hulls like a catamaran, but has flexible rubber sealing fore and aft between the hulls. Fans blow air into this air cushion between the hulls and rubber seals, and partly lifts the vessel up and out of the water.
