In the last halfcentury, highspeed water transportation has developed rapidly. Novel highperformance marine vehicles, such as the air cushion vehicle (ACV), surface effect ship (SES), highspeed monohull craft (MHC), catamaran (CAT), hydrofoil craft (HYC), wavepiercing craft (WPC) and small water area twin hull craft (SWATH) have all developed as concepts, achieving varying degrees of commercial and military success. Prototype ACV and SES have achieved speeds of 100 knots in at calm con tions; however, the normal cruising speed for commercial operations has remained around 3550 knots. This is partly due to increased drag in an average coastal s way where such craft operate services and partly due to limitations of the propulsion systems for such craft. Water jets and water propellers face limitations due to c itation at high speed, for example. SWATH are designed for reduced motions in a seaway, but the hull form is not a low drag form suitable for highspeed operation. So that seems to lead to a problem maintain water contact and either water propulsion systems run out of power or craft motions and speed loss are a problem in higher seastates. The only way to higher speed would appear to be to disconnect completely from the water surface. You, the reader, might respond with a question about racing hydroplanes, which manage speeds of above 200 kph. Yes, true, but the powertoweight ratio is extremely high on such racing machines and not economic if translated into a useful commercial vessel.
