Claim 0:
1. A ski-snowboard system for downhill snowboarding and uphill skinning, the system comprising:
a first ski having an outer edge with a substantially concave outer edge side cut and an inner edge with a substantially concave inner edge side cut, the inner edge side cut having a greater degree of curvature than the outer edge side cut, at least a portion of the inner edge having a cutaway therein forming a first ski inner edge groove;
a second ski having an outer edge with a substantially concave outer edge side cut and an inner edge with a substantially concave inner edge side cut, the inner edge side cut having a greater degree of curvature than the outer edge side cut, at least a portion of the inner edge having a cutaway therein forming a second ski inner edge groove;
an insert having a substantially convex first edge with a first tongue extending from the first edge, the first tongue to engage the first ski inner edge groove, the insert having a substantially convex second edge with a second tongue extending from the second edge, the second tongue to engage the second ski inner edge groove; and
the system having a first uphill configuration in which the first ski and second ski are separated, and a second downhill configuration in which at least a portion of the inner edge of the first ski is attached to at least a portion of the inner edge of the second ski to form a snowboard and the insert is fitted between the first ski and the second ski, with the first tongue of the insert engaging the first ski inner edge groove and the second tongue engaging the second ski inner edge groove to increase a torsional stiffness of the second downhill configuration.
