Abstract
Abstract A snow ski of sufficient width to hold both feet in close side by side position in conventional bindings or boot retainers. The ski has a stiff central body portion, with a flexible tail and an even more flexible nose or tip, and a minimum bottom camber. The relationship of the stiffness and flexibility is important to the performance of the ski. Advantages of the snow ski are extreme maneuverability, good pivot turn ability, controlled turns at all speeds and good support on powder snow due to the large surface area.
