Abstract: A boat hull form includes a dual circular curved outer surface area that is circular concave relative to the plane of symmetry of the hull when viewed horizontally parallel with the plane of symmetry of the hull, and circular convex relative to the plane of symmetry when viewed vertically parallel with the plane of symmetry of the hull, with the hull outer surface area extending in a vertical sense from a lower area extending in a direction that tangentially intersects the plane of symmetry or optionally a plane extending parallel with the plane of symmetry on the same side of the plane of symmetry as the dual circular curved outer surface area and upwardly in a direction tangentially intersecting the waterline plane of the hull or a plane extending parallel to the waterline plane.
