A ski offered is characterized in that - the front end of ski is designed in conformity with guide face structure of high-speed boat, and it is wider than rear part, - the sides of ski are formed sloping inwards and are sheeted - the bottom side of ski is curved upwards, and it is provided with grooves fulfilled with porous plastic material, which is saturated with ski liniment by injection, - the bottom side of ski is covered with bristly perforated leather, which is cut out so that bristles flatter with regard to skiing direction and do not impede the skiing, but leather incorporated in bottom side of ski prevents the backslipping when skier ascends the hill, and in that - forming of ski liniment layer between exterior surface of said leather layer and snow is carried out in the similar way as it happens using hydrostatic lubrication method, i.e., the liniment is being delivered to external layer of perforated leather through its capillaries by help of pressure created by skier's self-weight, thus during the skiing it moistens the leather and decreases the surface friction coefficient.
