Hull for watercraft, esp. sailing boats and surf boats - has broad stern, and narrow buoyancy-producing projection under hull decreasing in size toward hull and stern

摘要

The hull has a wide hull section, and below it, a longitudinal slim projection. The projection is positioned under the waterline, and generates buoyancy. It decreases in size toward hull and stern, and has a flat stern. The board hull section (1) increases in size in the rear section, below the waterline (WL), in the area, where the projection (2) decreases. The increase is of approx. the same size, as the decrease in the slim projection. The section below the waterline is of approx. even size from bow to stern. ADVANTAGE - Very stable against listing, dropping of stern during high seas is reduced.
