A water ski with improved torsional characteristics delimited on the upper side by the upper surface, on the bottom side by a concave surface and on the sides by curvilinear sidewalls. The ski has a tip at the front side and a tail on the rear side. On the central part of the ski, on the upper surface, a longitudinal groove is provided having a flat bottom surface connected with vertical longitudinal sides of the groove by rounded surfaces, wherein the groove decreases torsional and flexural strength, which depth and width reduce torsional and flexural stiffness of the central part of the ski. The width of the groove may be 30-80% of the width of the ski, and the depth of the groove may be 20-95% of the thickness of the ski.
