The air-lifted catamaran (ALC) is an innovative fast marine transportation concept, comprising the application and variation of a new, skirtless air cushion and air-lubrication, thus rendering it a hybrid between catamaran and surface effect ship (SES). Its features and capabilities are beyond current conventional high-speed monohull and catamaran. The present paper presents pertinent studies on stability concerning this craft, including dynamic stability, stability in turning and directional stability. The stability analysis takes into account air compressibility in the cushion, and is carried out in time domain. Some simulated results are presented and discussed, and requirements for design and operation of the craft based on IMO HSC Code 2000 are briefly outlined.
