Abstract: This invention relates to a marine vessel hull form, in particular to a high speed planing boat. It describes a new and distinctive shape of hull which, unlike other hull forms developed to date, features the shape which modifies the flow of water underneath and around it in such a manner that the waves behind the hull at speed are reduced to a minimum. This hydrodynamic effect results in reduced resistance and thus increased speed and/or reduced fuel consumption. Further, it will result in reduced wash behind the boat, an effect that will enable it to operate at full speed near shores where local regulations limit crafts' speed because of shore erosion caused by waves generated by boats and ships. The hull form described in this invention offers more stability than the planing traditional hulls do, due primarily to higher beam to length ratio and to the stern shape, which departs from the traditional "V", which is not particularly stable at speed or stationary.
