Sci-Five Concave

Sci-Five Channels: 
The Sci-Five Concave bottom to greatly increase the board's overall speed, control and responsiveness. This happens as water is rapidly pushed through the 5 tight hydrodynamic channels creating cavitation which gives lift in the tail thus minimizing friction which reduces drag which equals increasing speed. 

When riding on your rail the Scifive channels are engaged to give you heavy duty traction with out any sacrifice for maneuverability. The gradual 18 inch channels are narrow, and they also stop well short of the center of the board, this is designed specifically in order to allow you the freedom to spin, launch and carve in and around the pocket with ease.
