JS Industries Twin Fin

This set is designed for surfers looking for speed and projection. The large template and full tip make it ideal for generating drive down the line and maintaining momentum through turns, rather than just loose, pivot-heavy surfing.

The combination of epoxy resin, carbon, and the Soric SF2 core creates a stiffer, more responsive fin compared to standard polyester options. You will notice a snappier, more immediate reaction when you push through a turn, as the fins hold their shape better under pressure.

These are specifically designed for twin-fin setups. While they can technically fit into any standard twin-fin box, they are best paired with boards shaped with a twin-fin rocker and bottom contour in mind to ensure the performance characteristics match the board's design.

Yes, the Soric SF2 core is engineered to reduce the overall weight of the fin without sacrificing the stiffness required for high-speed performance. A lighter fin reduces swing weight, which helps the board feel more agile and easier to maneuver.

With a depth of 5.50 inches and a surface area of 23.03 square inches, these are considered large, high-performance fins. They provide more hold and drive than smaller, retro-style twin fins, making them a better choice for waves where you need to generate your own speed.
