ABSTRACT:
A displacement hull is formed by making a series of cuts in a curves sheet or panel of semi-resilient material. At least one primary cut begins at one end of the panel, and extends in one direction for a substantial distance along the panel, but terminates within the panel. At least one primary cut in the other direction runs substantially-parallel to the primary cut in the one direction and overlaps it for a substantial length of the hull. The panel must have enough resilliency, and the cuts from opposing directions must be long enough to provide at least one, elongated, relatively-narrow, very-flexible strip, within which the panel develops from a flat surface, at the termination of each of the primary cuts, to any desired angle at the start of each cut. Secondary cuts, curving away from the primary cuts along the flexible strip, in either direction, can provide various cruves to the keel or chines. Additional, tertiary cuts, curving away from the primary or secondary cuts, at or near their terminations, in the general direction of the primary cuts, ease the stress in the panel at the termination of the cuts. The edges of the adjacent portions of the beginnings of the primary and secondary cuts, which should be congruent, are drawn together and sealed in a watertight manner to make the hull.
