On a "rocker" ski, the tip, and sometimes the tail, comes off the ground sooner than with a cambered ski: this has the effect of moving the contact points toward the centre of the ski. The surface of the ski in contact with the snow is shortened and offers manoeuvrability and floatability in soft snow. When leaning into turns, the edge length offers more edge grip on hard snow. The longer the rocker, the better the handling of the ski.
