The snowboard comprises a lower face (7) with a front contact line (LCAV), defined as being a front limit of the contact zone of the lower face of the board on a plane horizontal surface (PH). The board is applied on the horizontal surface and a tip (2), defined as being the front part of the board, is curved upward in order to surmount obstacles. The tip has a front line of maximum width (LbV), defined as being the line of the lower face in the tip zone, in the place where its width (bv) has a maximum. The height (hAV) of the front line of maximum width, measured between the lower face and the plane horizontal surface is between 5 mm and 15 mm.
