A boat hull (10) extends between a stem (7) and a transom (8) and has chines (12) bounding chine planing surfaces (13) sloping outboard and down at (14). Convex major planing surfaces (15) each have a lower edge defined by a lateral planing surface (17), the inner edge forming the lower edge of a substantially vertical hull tunnel wall (20), the upper edge meeting a tunnel top (21). Between the respective port and starboard tunnel tops (21) is a vee keel (22) of substantially constant prismatic section and comprising a keel planing surface (23) bounded by upwardly and transversely sloping inner tunnel surfaces (24). The spaced recesses (18) formed thereby maintain a longitudinally prismatic form substantially for the length of the planing surface. The stem (7) above the chine forward (14) presents a conventional monohull appearance. The topsides, deck, interior space, and ratio of LOA to beam, all present as a conventional monohull. |
