The Airfish is a wing-in-ground (WIG) vehicle. Like the albatross or Second World War bombers running low on fuel, the craft takes advantage of the ground effect for fast, efficient cruising just above the surface of the water. Flying at about 7m(20ft) or lower it enjoys higher air pressure or a ‘cushion of air’ beneath its body and less lift-induced drag, reaching a maximum speed of 121mph or cruising speed of 90mph – much faster than a 30mph ferry, for example.
