BOAT WITH TWO CAMBERED PLANING SURFACES

Original (Chinese)

Method and apparatus of various embodiments of a hydrodynamic design of planing boat or vehicle employing two substantially dihedral planing surfaces featuring cambered hydrodynamic profiles with their base lines, positioned successively along length of the boat and comprising a forward planing surface of swept back plan form and an aft planing surface, which, in order to match conformally the disturbance of water surface generated by the forward planing surface, specifically configured and arranged spatially and angularly relatively the forward planing surface, so that within each vertical longitudinal plane a section of aft planing surface is displaced vertically and its base line is turned relatively the base line of corresponding section of the forward planing surface within the same vertical longitudinal plane by the height and angle of the wave trough generated by the forward planing surface at the location of said section of aft planing surface.
