Abstract: An apparatus for gliding on snow with improved stability and better edge-setting in turns includes a single board having a raised tip at the front and a heel at the rear, and a safety binding assembly for securely joining boots to the board. The safety binding assembly includes first and second bindings positioned on the board to prevent movement and rotation in translation, and to form an angle between 0 and 20 degrees relative to the longitudinal axis of the board. The bindings are longitudinally displaced so that the longitudinal distance between them is at most equal to 100 millimeters. The sides of the board include center portions which are concave in shape between the tip and heel of the board, and rectilinear portions located where the center portions of the sides intersect with the tip and heel of the board.
