A longitudinally extending rib protrudes from a top of the middle portion and is laterally spaced from a longitudinal centerline of the ski. An aperture is disposed in the longitudinally extending rib for permitting attachment of the ski to a snowmobile. A ramp extends from a first point to at least a second point. The first point is disposed longitudinally between the front portion and the aperture, and closer to the top of the middle portion than the aperture. The second point is disposed longitudinally between the first point and the rear portion, and further away from the top of the middle portion than a lower end of the aperture. The longitudinally extending rib is disposed between the longitudinal centerline and the ramp. A snowmobile having a pair of the above-described skis is also described.Type: ApplicationFiled: June 26, 2008Publication date: December 31, 2009Applicant: BOMBARDIER RECREATIONAL PRODUCTS INC.Inventor: Rene LEMIEUX
