Abstract

A ski is provided with a device for damping vibrations which arise in use in the ski by the effect of impacts between the asperities of icy snow and the tip and tail of the ski itself. The device consists of at least one concentrated mass which is floatingly carried by at least one end of the ski in such a way as to be free to move in the vicinity of this end.
