ABSTRACT:
A ship hull has a general frame form defining a bottom surface and two side surfaces. The bottom surface of the hull has a horizontal bottom section that extends longitudinally of the hull midway between the two side surfaces of the hull, and the bottom surface of the hull also has two inclined bottom sections that are located entirely below the design waterline plane and are joined to the horizontal bottom section along respective sides thereof and to the side surfaces respectively. Each join is along a clearly defined longitudinal intersection edge, whereby each side of the hull is divided into at least three clearly defined portions. The width of the horizontal bottom section and of each of the inclined bottom sections is at least 20% of the maximum beam of the hull, and the inclined bottom sections extend over a substantial part of the length of the hull.
