FCS FCS II Channel Islands Upright Performance Core Thruster Fins - White

Upgrade your surfboard with the FCS II Channel Islands Upright Performance Core fin set. This high-performance thruster set was designed by CI Surfboards for surfers who crave pure speed and lightning-fast, sharp turns (pivoting). Thanks to the more vertical 'upright' profile, your board responds instantly to every input, making it ideal for quick turns in the pocket and easily finding release in the lip. An essential upgrade for your favorite performance shortboard or daily driver.

Speed and Direct Response: The Channel Islands Upright Template

The FCS II Channel Islands Upright Thruster set stands out because of its specific shape. While many all-round fins have a traditional backward bend (rake) for long, drawn-out turns, this CI fin stands much more vertically in the box. This 'upright' design provides a shorter turning radius and unparalleled responsiveness. You retain an exceptional amount of speed (drive) from the bottom turn, after which you can direct the board sharply and vertically into the top.

For which surfers and conditions?

This Channel Islands fin set performs everywhere quick decisions and sharp maneuvers are required, from powerful beach breaks to hollow reef breaks.

• Ideal board type: Excellent for performance shortboards and hybrid shapes. Also works fantastically on boards with a flatter rocker, because the vertical fin template makes the board instantly much more maneuverable and loose.

• FCS II Click System: Fully compatible with the tool-free FCS II Fins System. You click the fins into your board in no time and are ready for your session.

Performance Core (PC) Construction

Made with FCS's premium Performance Core (PC) technology. Through an advanced production process with a foam core and high-quality resin, these fins mimic the flex pattern of traditional fiberglass fins, but with a significant weight reduction. The rigid base guarantees stability and drive, while the flexible tip provides a dynamic, lively 'whip' when you accelerate out of your turns.
