From the general dimensional and mechanical similarity theory it follows that a condition of steady motion of a given shape bottom with constant speed on the surface of water is determined by four nondimensional parameters. By considering the various systems of independent parameters which are applied in theory and practice and special tests, there is determined their mutual relations and their suitability as planing characteristics.
