The ski consists of a body (2) with a supporting surface defined by front and rear contact lines (A,D') and a central zone (ZRC) of more or less constant thickness (E) and a length which is more than 40 per cent of the length (Lp) of the supporting surface. It has two zones (ZA and ZED) of variable thickness, located before and after central zone. The length of the central zone is between 600 and 900 mm, and its thickness is between 22 and 35 mm, or between 15 and 30 mm. The central zone of the ski can be made from one piece of material or in two layers, with the forward and rear sections joined to it by strips of a visco-elastic material. |
