FCS Channel Islands CI Keel Twin Fins

Yes, these are designed specifically for the FCS II system, allowing for tool-less installation. They will click directly into any standard FCS II fin box.

Performance Glass provides a stiffer, more consistent flex pattern than molded plastic or composite fins. This gives you more drive and responsiveness, especially when pushing hard through turns at higher speeds.

While they are optimized for fish models, they perform well on any twin-fin setup or funboard where you want to emphasize speed and flow. They are particularly effective on boards with wider tails that benefit from the extra surface area of a keel template.

These fins excel in smaller to medium-sized waves where maintaining momentum is key. Their keel shape helps you generate speed in softer sections, though they remain stable enough to handle more powerful, carving turns.

The keel template offers a looser, more fluid feel that encourages down-the-line speed and drawn-out turns. You will notice less drag than a thruster setup, which makes the board feel faster and more lively on the wave face.
