| description | Disclosed is a bi-directional watercraft, such as a surfboard, fin systems therefore, and method of use. Example fin systems may allow a user of the watercraft to perform bi-directional maneuvers and stunts. The watercraft may be bi-directionally symmetric or asymmetric with fins mounted on its undersurface on both ends. When underway, the fins at the operating rear of the watercraft deploy for stabilization in cross-currents, while the fins at the operating front remain pivoted out of the way so that they do not "catch" water and destabilize the watercraft. When the watercraft reverses in direction, and the front and rear ends swap with one another, biasing mechanisms cause the fins now at the front to pivot away and hydrodynamic forces cause the fins now at the rear to deploy. In some cases, holders keep the fins from inadvertently deploying when they are not needed. |
