Abstract: The invention relates to a boat hull, in particular for high speed crafts, the underside of which has in at least one longitudinal section through or, respectively, parallel to the center plane a profile similar to the profile of an aircraft wing, the vertex of the longitudinal sectional profile, with respect to the bow-side end point of the chord of the longitudinal sectional profile, being positioned in the front half of the entire length of the chord. According to the invention there is provided that the chord (1) of the unloaded boat hull (2) includes an angle () with the horizontal plane defined by the water level (3) of 1.degree. to 3.degree., preferably of 1.5.degree. to 2.5.degree., in particular of 1.8.degree. to 2.2.degree., so that the stern-side end point (4) of the profile is positioned at the lower end point of the stern or, respectively, of the transom (5) below the water level (3).
