Gliding board with a damping device

A gliding board with a vertical movement damping system in the front or rear zone of the board, said system including an arm the first end of which is integral with an attaching point located in the front or rear zone of the board and whose second end is integral with a piston of a hydraulic device connected to the board near the attaching point, said hydraulic device applying a damping force during a movement of the second end of the arm in order to dissipate part of the kinetic energy from the front or rear zone of the board transmitted by said arm,

• wherein when the arm moves responsive to a downward movement of the attaching point corresponding to a counter-bending movement of the board, the damping force applied by the hydraulic device is less than the damping force applied when the arm moves responsive to an upward movement of the attaching point corresponding to a board bending movement.
