A skateboard/ski combination wherein the four wheels of a traditional skateboard have been removed, while the skateboard trucks remain in place, and are then replaced with four ski apparatuses. An anchoring plate connects springs from the underside of the skateboard deck to the ski apparatus base that maintains a traditional ski shape, with rails that protrude outward from the front and rear of the ski base, still maintaining a traditional ski shovel shape. The ski base, which has a flat or concave surface perpendicular to the length of the ski, contains a radius positioned longitudinally to the ski length (rocker) that then transitions to a small radius at the front and rear of the skis, thereby providing a traditional ski shovel in the front and rear of the ski base. Metal or plastic rails are mounted to the ski base on opposing sides of the base in a vertical fashion, extending below the surface of the base. The rails have a radius positioned longitudinally to the ski length (rocker) that transitions to a small radius at both the front and rear ends of the base. An alternative spring suspension system uses torsion springs located in the vicinity of the axle hole on the skateboard truck. This combination allows the user to perform traditional skateboard maneuvers on snow.

We claim: 1. A skateboard/ski combination comprising: (a) a skateboard deck having upper and lower surfaces and opposite front and rear ends; (b) a front truck mounted on the lower surface of the deck disposed toward the front and a rear truck mounted on the lower surface of the deck disposed toward the rear, each said truck having a body supporting a transversely extending axle having opposite ends; (c) an anchor plate interposed between the lower surface of the deck and each of said trucks, each said anchor plate having opposite sides with connectors on opposite sides of the plate; (d) a ski pivotally coupled to the ends of each of said axles, said skis each having a length, inboard and outboard sides, a base and opposite ends, said skis being continuously curved along their length having a rocker with a first larger radius of curvature along its length intermediate the ends and transitioning at the opposite ends to curved shovels each having a second radius of curvature smaller than the first radius of curvature; (e) rails extending along the opposite sides of said skis, each rail projecting below the associated ski base, said rails being detachable from said skis; and (f) detachable extension springs extendable between the connectors on the anchor plates and the inboard sides of the associated ski whereby the rider can selectively attach springs between the anchor plates and the skis to apply tension to the skis to selectively adjust performance characteristics of the skateboard/ski combination without the use of tools. 2. A skateboard/ski combination according to claim 1 where said connectors comprise holes in said plate. 3. A skateboard/ski combination according to claim 1 wherein said connectors comprise prongs on said plate. 4. A skateboard/ski combination according to claim 1 wherein said rails are made of metal. 5. A skateboard/ski combination according the claim 1 wherein said rails are made of plastic. 6. A skateboard/ski combination according to claim 1 wherein said base surface is flat. 7. A skateboard/ski combination according to claim 1 wherein said base surface is transversely concave. 8. A skateboard/ski combination according to claim 1 wherein said rails are interchangeable in order to adjust performance and to quickly and easily repair or replace worn or damaged rails. 9. A skateboard/ski combination according to claim 1 further including a leash and cuff assembly that attaches the skateboard/ski combination to the rider. 10. A skateboard/ski combination according to claim 1 wherein said skis are constructed of plastic. 11. A skateboard/ski combination according to claim 1 wherein said skis are constructed of metal. 12. A skateboard/ski combination according to claim 1 wherein said skis are constructed of a composite material.
