A sit-ski includes a ski and a base frame which is mounted on the ski. A seat support is pivotally mounted on the base frame for rotation about an axis that is above the ski and substantially perpendicular to the axis of the ski. This allows the seat to move on an arcuate path about the axis of rotation. A shock absorber has one end which is connected to the seat support between the seat and the axis of rotation, and another end which is attached to the base frame. Accordingly, movement of the seat on its path causes compression or elongation of the shock absorber. The ratio for movement of the seat, relative to compression of the shock absorber is approximately 3.5:1.
