ABSTRACT:
A hull form for a vessel which hull form is deep-Vee based and is constructed and arranged for use in a displacement mode. The hull includes a bow section which incorporates a plurality of lateral grooves or, alternatively, a single lateral formation and which extends below the base or datum line of the hull in a streamlined teardrop configuration. Preferably, the hull has deep-Vee deadrise angles (1) whose magnitudes in the region of the transom of the hull are not less than 20.degree.. The surfaces extending between the keel and the water line length are non-planar and have developable convex and concave geometry, all buttock lines of the hull having a negative inclination of between substantially 1/2.degree. and substantially 4.degree.. The invention enables the known advantages of deep-Vee based hull forms to be used in displacement mode vessels having relatively large displacements where, heretofore, "round-bilge" hull forms very greatly predominated.
