Abstract

The boat hull (A) has a relatively flat bottom part (2) with the formation of a very weak V, and flat sides (1) sloping gently upwards. These sides then merge into the stern's (3) lower part. The union between the sides and the bottom is so shaped that air can move through and out under the hull, characteristic of the so-called 'sliding' hull.
