ABSTRACT:
A skag for a ski, such as a vehicle ski. The skag includes a carrier platform to be attached to the bottom surface of a ski. First and second longitudinal rails are disposed on the bottom surface of the carrier platform. The longitudinal rails are spaced apart laterally from one another. The first and second rails are staggered, such that the forward end of the first rail is farther forward than the forward end of the second rail, and the aft end of the second rail is farther aft than the aft end of the first rail. The aft end of the first rail may be at least as far forward as the forward end of the second rail. At least one of the rails may have a longitudinal keel disposed thereon, and at least one of the rails may have a hard-surface weld-disposed thereon. When two skags are used together, as on two adjacent skis, the rails and/or keels on the skags may be arranged so that one skag is a mirror reverse of the other.
