Abstract: A snow ski board (1) such as a ski, monoski, or a snowboard, with a vertical plane of general symmetry (P) includes a body or base (2) that includes at least in a binding zone (3) two hollow lateral recesses (8a, 8b) extending longitudinally. A longitudinal rib (11) is defined between the recesses. Each of the longitudinal recesses (8a, 8b) opens at least towards the top (HA). The body (2) is affixed, at least in the binding zone (3) to a supplementary element (4) having two lateral longitudinal parts (4a, 4b) which extend longitudinally and parallel. The two lateral longitudinal parts (4a, 4b) are affixed into the longitudinal recesses (8a, 8b) and are linked by at least one transverse connector (4c).
