FCS Surfboard Fins FCS II Channel Islands Solution PC Tri Fins

Surfers around the world have a problem with lackluster waves and Channel Islands has the Solution! They have teamed up with CI to produce a brand new Tri Fin Set for their new Solution model.
The FCS II Channel Islands Solution PC Tri Fins are designed in collaboration with Channel Islands Surfboards and based on the proven CI Upright template by Britt Merrick. Built to complement the CI Solution model and beyond, this fin set delivers speed, responsiveness, and tight turning performance across a range of wave types.

The upright template promotes quick direction changes and vertical surfing, making it ideal for punchy, hollow waves and critical sections. At the same time, the fuller profile from base to tip provides the drive and control needed to push hard through turns, while still maintaining a loose, free-feeling release off the top.

Designed to suit boards with a more relaxed rocker, this fin excels in generating immediate start-up speed and acceleration from take-off—perfect for everyday conditions where waves may lack power.

Constructed in Performance Core material, these fins offer a lightweight feel with a progressive flex pattern, delivering a balance of drive, control, and responsiveness.
