Dual-edged snowboard and snow skis

A sled structure configured and arranged for gliding on snow, the sled structure comprising:

• a top deck surface comprising:
• an inner top surface;
• an outer top surface that includes an outer top surface portion that is disposed vertically higher than and substantially parallel with at least a portion of the inner top surface;
• and
• an upper step that is disposed along an upper interface between the substantially parallel and laterally adjacent portions of the inner top surface and the outer top surface, wherein a lateral width of the outer top surface is significantly greater than a lateral width of the upper step;
• and
• a base deck surface comprising:
• an inner base surface in opposition to and below the inner top surface;
• an outer base surface disposed laterally adjacent to the inner base surface and in opposition to and below the outer top surface;
• an inner edge disposed along a lower interface formed by laterally adjacent portions of the inner base surface and the outer base surface, wherein a lowest portion of the inner edge is disposed flush with the laterally adjacent of the inner base surface;
• and
• an outer edge disposed at an outer perimeter of the outer base surface, wherein an outermost portion of the inner edge is laterally intermediate an outermost portion of the upper step and the outer edge, such that the outermost portion of the inner edge is disposed directly below a region of the outer top surface portion that is substantially parallel with the portion of the inner top surface.

A deck comprising:

• an upper deck surface that includes and outer region, an inner region that is lower than and substantially parallel to the outer region, and an upper step that is laterally intermediate the outer region and the inner region, wherein a lateral width of the outer region is significantly greater than a lateral width of the upper step;
• a lower deck surface configured and arranged to glide on a surface;
• a longitudinal axis of symmetry that subdivides the deck into a first longitudinal portion and a second longitudinal portion;
• an outer snow carving means disposed on the lower deck surface of the first longitudinal portion;
• and
• an inner snow carving means disposed on the lower deck surface of the first longitudinal portion, wherein a substantially flat lowest portion of the inner snow carving means a lowest is disposed flush with and substantially parallel to a lowest portion of the lower deck surface and intermediate the outer snow carving means and the longitudinal axis of symmetry, wherein the substantially flat lowest portion of the inner snow carving means that is substantially parallel to the lowest portion of the lower deck surface is laterally intermediate a portion of the upper step and the outer snow carving means.
