The inventive combination of a stern wedge and a stern flap demonstrates hydrodynamic properties which, for purposes of enhancing the powering performance of a ship, are superior to those of either a solitary stern wedge or a solitary stern flap. For many inventive embodiments, the stern wedge portions lower surface and the stern flap portions lower surface are slanted at approximately equal angles with respect to the buttock centerline, thereby optimally consolidating the stern portions lower surface and the flap portions lower surface so as to effectively create an overall hydrodynamic lower surface which is slanted approximately at one and the same angle.
