FCS II MR PC Twin

The Twin + 1 configuration gives you the speed and loose, playful feel of a twin fin, but the small center stabilizer adds a crucial bit of hold. This helps prevent the tail from sliding out unexpectedly during steeper turns or in more demanding surf.

These fins use the FCS II system, which is designed for tool-less installation. They are compatible with any board equipped with FCS II fin boxes, though they are specifically shaped to complement fish, funboards, and dedicated twin-fin designs.

Performance Core fins are designed to feel like traditional fiberglass fins but with a significant reduction in weight. They offer a consistent, reliable flex pattern that helps you maintain speed through turns while remaining responsive.

Yes, you can remove the center stabilizer if you want a looser, more traditional twin-fin experience. However, the template is specifically engineered to work as a set, so you may find the board feels significantly different—and potentially less stable—without that third fin.

While these fins are high-performance, they are quite versatile. If you are transitioning from a longboard to a fish or a funboard, the added control from the stabilizer makes this a forgiving and approachable way to experiment with a twin-fin feel.
