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).
Claims8
A watercraft, comprising in combination:
- two gliding surfaces for gliding over a water surface arranged in a V-shaped array on either side of a longitudinal keel line, each gliding surface having a longitudinal axis and being configured to support the watercraft for gliding on the water surface substantially by the sole support of a single one of the gliding surfaces,
- a keel portion establishing a longitudinal keel line formed between and connecting the two gliding surfaces in the V-shaped array formed by said two gliding surfaces configured with a bow portion extending upwardly from the keel line to extend substantially above the water surface when the watercraft is gliding on one of the gliding surfaces, and
- means disposing the two gliding surfaces to diverge backwardly from the bow portion.
