1. A snow-riding device having edges running along sides thereof and an undersurface between a forward end and a rearward end, the device comprising:
- a tip at the forward end;
a tail at the rearward end;
a mid-portion having a waist, a forward end, and a rearward end, the waist having a width smaller than the average of the widths of the mid-portion forward and rearward ends, such that a concave sidecut is created along the mid-portion;
a fore-body between the tip and the forward end of the mid-portion, the fore-body having a rearward end where it meets the mid-portion and a forward end where it meets the tip, the fore-body being widest at its rearward end and being straight or convex along its side to its forward end, the sides of the fore-body converging towards the tip; and
an aft-body between the rearward end of the mid-portion and the tail, the aft-body having a rearward end where it meets the tail and a forward end where it meets the mid-portion, the aft-body being wider at its forward end than at its rearward end;
wherein, the fore-body is rockered along most of its undersurface, whereas the undersurface of the mid-portion is cambered, camber extending between a fore-body/mid-portion transition to a mid-portion/aft-body transition, such transitions also coinciding with the sidecut transitioning from concave to straight or convex and also being the widest regions of the device.

Abstract
A ski in accordance with the invention increases in width from a tip or shovel portion to a mid-portion. The mid-portion includes at least a slight sidecut. The ski then decreases in width from the mid-portion to a tail portion. The ski also includes an undersurface with a substantial portion being rockered. A substantial portion of the mid-portion of the ski is not rockered.

20. A snow riding device comprising:
-
a shovel end and a tail end each having a raised tip portion; a sliding surface formed on an underside of the device extending between the shovel end and tail end; a binding secured to an upper surface of a central portion of the device; and sidewalls comprising; a concave portion formed along the central portion having concave sidecuts; and non-concave portions extending beyond the central portion from the concave sidecuts to the raised tip portions of the shovel end and tail end, the non-concave portions converging towards the tip portions; wherein substantially all of the sliding surfaces coinciding with the non-concave portions of the sidewalls are rockered and substantially all of the sliding surface in the central portion is cambered. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31)

32. A snow riding device comprising:
-
a shovel end and a tail end each having a raised tip portion; a sliding surface formed on an underside of the device extending between the shovel end and tail end; a binding region on an upper surface of a central portion of the device; and sidewalls comprising; a concave portion formed in the central portion having concave sidecuts; and non-concave portions extending from the concave sidecuts to the raised tip portions of the shovel end and tail end, wherein an uppermost point of the tail end is higher than an uppermost point of the shovel end relative to a horizontal plane parallel to the sliding surface proximate the central portion.

33. A snow riding device, having edges running along sides thereof and an undersurface between a forward end and a rearward end, the device comprising:
-
a tip at the forward end; a tail at the rearward end; a mid-portion having a waist, a forward end, and a rearward end, the waist having a width smaller than the average of the widths of the mid-portion forward and rearward ends, such that a concave sidecut is created along the mid-portion; and a fore-body between the tip and the forward end of the mid-portion, the fore-body having a rearward end where it meets the mid-portion and a forward end where it meets the tip, the fore-body being widest at its rearward end and being generally straight or convex along its side to its forward end, the sides of the fore-body converging towards the tip; wherein, the fore-body is rockered along substantially all of its undersurface, whereas substantially all of the undersurface of the mid-portion is cambered, a transition between the mid-portion and the fore-body forming a widest region of width along the device, the sides converging toward the tip beyond the transition. - View Dependent Claims (34, 35, 36)
