Air Supported Vessels (ASV) utilise pressurised air, generated by lift fans and fed into hull integrated cavities to support a significat part of the operational displacement, often up to 85%.

It is importat to distinguish the ASV concept from "air cavity" and "air lubrication" solutions. The latter concepts are giving non or only marginal lift contribution. The ASV's are closer to the hovercraft in terms of air cushion support. The ASV's do not need rubber skirts og bags as seen on hovercrafts and conventional SES vessels. A major advantage.

The air cushion chambers are integrated partsin the hull design where the perifhery enclosures are rigid parts. The hulls are designed to minimize air ventilation when operated in a sea state and in calm waters. The invention reduces the wetted surface (friction between hull and water) to a minimum. In addition, the ASV's have very effective motion damping characteristics due to the patented hull configurations.

The ASV technology covers both monohull and multihull configurations and we encourage the reader to study the rest of the
