Our 3-Inch Unbreakable Removable Center Flex Fin is a center fin compatible with any U.S. fin box. All center fins come with a Fast Fin Release System, which holds the fin in place with just a 90-degree twist of the system. The Fast Fin Release System is transferable from one center fin to another.
This fin is 100% unbreakable, and can withstand contact with rocks and the seafloor. The low profile of the 3-inch fin is ideal for shallow water paddling. Its curved design allows the fin to go over rocks without getting hung up. The added surface area allows your board to track straight in all paddling conditions.
