FCS II Channel Islands Upright Performance Core Thruster Fins

Upgrade your surfboard with the FCS II Channel Islands Upright Performance Core fin set. This high-quality thruster set has been 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 tight turns in the pocket and finding an easy release on the lip. An essential upgrade for your favourite performance shortboard or daily driver.

Speed and Immediate Response: The Channel Islands Upright Template

The FCS II Channel Islands Upright Thruster set stands out thanks to its specific shape. Whilst many all-round fins have a traditional backward rake for elongated turns, this CI fin sits much more vertically in the box. This ‘upright’ design ensures a tighter turning radius and unrivalled responsiveness. You retain an exceptional amount of speed (drive) coming out of the bottom turn, after which you can steer the board directly and sharply upwards into the top.

Suitable for which surfers and conditions?

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

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

• FCS II Click System: Fully compatible with the tool-free FCS II Fins System. You can click the fins into your board in a jiffy and you’re ready for your session.

Performance Core (PC) Construction

Made using FCS’s premium Performance Core (PC) technology. Through an advanced manufacturing process utilising a foam core and high-quality resin, these fins replicate the flex pattern of traditional fibreglass fins, but with a significant weight saving. The stiff base ensures stability and drive, whilst the flexible tip provides a dynamic, lively ‘whip’ as you accelerate out of your turns.
