HYDROFOIL -- Mark Rice HYSWAS Explained -- Hydrofoil

Mark Rice is the president of MAPC Maritime Applied Physics Corp's a research and development company in Baltimore, Maryland. (HYSWAS)
HYSWAS Hydrofoil Small Waterplane Area Ship is a hydrofoil craft that receives typically 70% of its lift from a single buoyant pod located below a hull that at rest supports the other 30% of total weight. The pod or “lower hull” has its lift augmented by fore and aft hydrofoils. The lower hull is connected to the upper hull by a rigid strut. The HYSWAS is stable at rest because of the hydrostatic characteristics of the upper hull. Underway the foils generate lift that increases with speed, and raises the upper hull out of water. Dynamic stability is achieved by Active Flight Control System that regulates roll, pitch, and flying height. The result is stable passage through significant waves and in some cases, contour flying over ocean swells. Furthermore, Marks tells us the history of this company and their cutting edge roll played in the development of the HYSWAS concept. He also describes the parallel growth of the International Hydrofoil Society and its past and long term president John Meyer.
