Futures Performance Fiberglass Fin

No, this fin is specifically designed for the Futures fin system. It will not fit into standard US Box (center box) longboard setups.

A 2+1 setup uses a larger center fin paired with two smaller side bites. This configuration offers the stability and hold of a single fin while providing the responsiveness and drive of a thruster, making it ideal for longboards that need a bit more maneuverability.

Fiberglass is stiffer and more durable than plastic or composite materials. This provides a consistent, predictable flex pattern that holds its shape well through turns, giving you more stability and drive in varied wave conditions.

A 7-inch fin is generally best suited for mid-lengths or longboards where you want a balance of pivot and hold. If you are running a 2+1 setup, this size provides enough surface area to act as the primary stabilizer without feeling too restrictive.

While it is designed as a 2+1 center fin, you can technically use it as a single fin if your board's box allows. However, at 7 inches, it may feel smaller and looser than a traditional single fin, which is typically larger and more upright.
