ABSTRACT:
This invention relates to an improved snowmobile ski having a vertical fin on the topside of the ski with a surface area large enough to minimize or prevent sideways slippage of the ski during a turn. The fin, if a single fin is used, is located adjacent the outboard edge of the ski. A snowmobile ski with dual topside fins having outwardly projecting lips along the upper edges of said fins has improved performance in deep snow.
