Abstract
A snowmobile steering ski comprises a longitudinally extending body having a front portion, a central portion, a rear portion, a top surface configured to be secured to a snowmobile, and a bottom running surface configured to travel or glide over snow. The steering ski comprises at least one keel blade typically removably mounted to the body and downwardly extending from the bottom surface and generally extending longitudinally along at least a portion of the bottom surface. The bottom surface is further slightly upwardly arched, generally along the central portion thereof, such that the bottom surface defines a generally front pressure zone and a generally rear pressure zone. The rear pressure zone is located longitudinally behind the at least one keel blade, and is configured for substantially filling the trace(s) formed in the snow by the at least one keel blade such that the steering ski leaves little or no trace(s) in its wake.
