Abstract
A V-bottom for fast motor boats with longitudinal reaction walls reacting to a lateral trust from an air-water mixture which are substantially parallel and symmetrical in relation to keel is formed so that the reaction walls are the walls of flat-based grooves in a bottom joined to a flat base by a widely curving radius, or the reaction walls are the walls of ribs having a substantially trapezoidal cross-section and a flat horizontal lesser external base.

Hull for fast motor boats, comprising a V-shaped hull bottom surface extending substantially the length of the boat, longitudinal reaction walls which reacting to a lateral thrust from an air-water mixture and are substantially parallel and symmetrical in relation to a keel, characterized in that the reaction walls are walls of grooves each having two walls and a base, and in each of the grooves the base being fiat, the two walls being at 90°to the base, and the two walls being each joined to the base by a widely curving radius, the grooves being recessed inwards from the V-shaped hull bottom surface.
