ABSTRACT:
In order to attain a superior performance of a sailboat (1) under different conditions, e.g., dead calm, average winds, high waves, etc., the invention makes possible that the two longitudinal sides of the hull essentially correspond with the gliding surfaces (11,12) of surfboards. These gliding surfaces are arranged in the shape of a V, may contact one another within the central region (T) of the watercraft (1) and transform into a transition area that forms the bow within the front region by providing additional side walls (15,16).
