ABSTRACT:
A snowmobile ski including an elongate plywood body member and a flexible, air-impervious material covering the bottom surface of the body member. The body has a generally upwardly curved forward end and a width substantially greater than conventional snowmobile skis to provide support in soft snow, slush, ice, and the like. The flexible material covering the bottom surface of the body member is attached, and hermetically sealed, to the bottom surface along the outer margins and a longitudinal center line of the body member by a thin metal strap and a series of spaced bolts.
