Future Fin System. The Fling Surfboard is designed as a shorter and more modern/high performance take on the keel fin fish, it has all the grooviness of the throwbacks with none of the weird oldness. It’s young, rad, and classy all at the same time. Crazy fast down the line, lots of lift, smooth and tight through carves, and progressive in the pocket. It’s versatile: it can be surfed assertively off the tail, or with light feet for those that love airs.
