Sailing boat monohull with contoured base forming two mini-hulls with concave centre section, all below waterline when boat is level

摘要

The main hull has two convex mini-hulls (3), whose axes (5) are parallel. Each has a tapered nose (4). They are joined by and are continuous with the concave centre section (8), which remains below the water line when the boat is level. A stabiliser (20) restricts the volume of water displaced in the funnel-shaped channel (11).
