| 摘要 |
The disclosure herein is directed toward systems and methods for supporting a person and enabling motion of a person across a surface of snow while satisfying the countervailing requirements of increasing surface area for weight-carrying capacity on soft snow and reducing the opposing forces, like for example drag and friction, in hard snow. More specifically, a snowboard described herein includes an inner edge and an outer edge, and allows the rider to control the amount of board-to-snow contact. This snowboard is configured to improve rider support, increase speed and enhance safety performance. |

1. A snowboard, comprising:
a board having an upper surface and a lower surface, a first edge and a second edge, and a first and second end, the upper surface having locations for a first binding and a second binding to allow the bindings to be arranged transverse to a longitudinal axis extending through the first and second ends, the lower surface having a first and a second rail extending along the longitudinal axis and being separated by a recess extending along the longitudinal axis, the rails and the recess each having a width measured transverse to the longitudinal axis and the width of the recess being greater than the width of each respective rail, and the first and second rails and the recess extending substantially a length of the lower surface, and the second edge being located at a periphery of the upper surface, and the first edge being located on the lower surface and closer to the longitudinal axis than the second edge, wherein the first and second rails have surfaces for contacting a snow surface, the first and second rail surfaces being tapered to narrow a thickness of the respective rail from the recess to the first edge of the board. |
