The VT1 introduced several new features on what is even now a fairly large craft, about 100 ft overall length and 90 tons displacement. The cushion system, including the air feed and stability devices, were new and were developed using ship tank models; the skirt followed closely the system developed by Hovercraft Development Ltd (HDL) and successfully demonstrated on craft fitted with air propulsion; the VT1, however, used a modern but conventional marine propulsion system. Skegs to carry the propeller shafts were introduced as a new feature to give the craft a semi-amphibious capability while retaining the marine screw, the combination giving as low airborne noise level, good directional stability and high thrust at low speeds.
