Disclosed is a plastic boat hull and a method for making a plastic boat hull by roto-molding a thermoplastic material in a mold cavity. The resultant boat hull in a preferred embodiment has an upper hull portion which is identical to the lower hull portion. The forebody, in a preferred embodiment is identical to the afterbody except that one is rotated 90 DEG with respect to the other about the longitudinal axis of the hull. The boat hull shape provides for minimal weight, windage and surface area. The vessel has a wave-piercing bow which creates an asymmetric water plane even though the forebody and afterbody are conceptually identical. The asymmetric water plane reduces pitching of the hull in rough water. In a preferred embodiment, two smaller hulls and one larger hull are combined with cross beams to form a trimaran sailboat.
