| 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 second edge being located at a periphery of the upper surface, and the first edge being located on the lower surface laterally spaced away from the second edge to be located closer to the longitudinal axis than the second edge, the first edge being made with a first material, the second edge made with a second material, and the second material has different material properties than the first material, wherein the first material has a first coefficient of friction which is lower than a second coefficient of friction of the second material. |
