Snowmobile ski system

Abstract

A snowmobile ski system for reducing frictional resistance and improving overall control of a snowmobile ski. The snowmobile ski system includes a ski having a body, a lower surface, an upper surface, a saddle, and a plurality of dimples within the lower surface of the ski. The plurality of dimples may have various shapes, sizes, depths, designs and patterns to assist in reducing the frictional resistance of the ski upon a snow surface. The plurality of dimples within the lower surface of the ski create a plurality of air pockets between the lower surface and the snow surface during forward travel.

I claim:  
     
         1 . A snowmobile ski system, comprising: 
 a snowmobile ski having a lower surface and an upper surface; and    a plurality of dimples within said lower surface of said snowmobile ski.    
     
     
         2 . The snowmobile ski system of  claim 1 , wherein said plurality of dimples cover at least fifty-percent of said lower surface.  
     
     
         3 . The snowmobile ski system of  claim 2 , wherein said plurality of dimples cover at least ninety-percent of said lower surface.  
     
     
         4 . The snowmobile ski system of  claim 2 , wherein said plurality of dimples have a circular shape.  
     
     
         5 . The snowmobile ski system of  claim 4 , wherein said plurality of dimples are concave.  
     
     
         6 . The snowmobile ski system of  claim 5 , wherein said plurality of dimples are randomly positioned within said lower surface.  
     
     
         7 . The snowmobile ski system of  claim 5 , wherein said plurality of dimples are positioned within a pattern within said lower surface.  
     
     
         8 . The snowmobile ski system of  claim 1 , wherein said plurality of dimples are comprised of at least two sections separated a finite distance from one another.  
     
     
         9 . The snowmobile ski system of  claim 1 , wherein said plurality of dimples are comprised of a consistent size.  
     
     
         10 . The snowmobile ski system of  claim 9 , wherein said plurality of dimples are comprised of a consistent shape.  
     
     
         11 . The snowmobile ski system of  claim 10 , wherein said plurality of dimples are comprised of a consistent pattern.  
     
     
         12 . The snowmobile ski system of  claim 11 , wherein said plurality of dimples are circular in shape.  
     
     
         13 . The snowmobile ski system of  claim 11 , wherein said plurality of dimples are comprised of a polygon shape.  
     
     
         14 . The snowmobile ski system of  claim 1 , wherein said plurality of dimples are comprised of a random size.  
     
     
         15 . The snowmobile ski system of  claim 1 , wherein said plurality of dimples are comprised of a random shape.  
     
     
         16 . The snowmobile ski system of  claim 1 , including a keel extending longitudinally from said lower surface, wherein said keel includes a portion of said plurality of dimples.  
     
     
         17 . The snowmobile ski system of  claim 1 , wherein each of said plurality of dimples have a width less than {fraction (5/8)} inches.  
     
     
         18 . The snowmobile ski system of  claim 1 , wherein each of said plurality of dimples have a width greater than {fraction (1/4)} inches.  
     
     
         19 . The snowmobile ski system of  claim 1 , wherein said plurality of dimples are molded into said lower surface.  
     
     
         20 . The snowmobile ski system of  claim 1 , wherein said plurality of dimples are carved out of said lower surface.
