Patent ID: 7690674

Claim:
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.
