Surfers around the world have a problem with lacklustre waves and Channel Islands has the Solution! We have teamed up with CI to produce a brand new Tri Fin Set for their new Solution model.
£119.95
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.
The Channel Islands Solution Tri set feels fast, lively, and highly responsive.
The upright template allows for tight, vertical turns and quick transitions in the pocket, while the fuller outline provides the confidence to push hard through manoeuvres. Off the bottom, the fin generates immediate speed, and off the top, it releases cleanly for a loose, responsive feel.
The result is a balanced fin that blends speed, control, and freedom—perfect for surfers looking to maximise performance in everyday and punchy conditions alike.
Built for speed, tight turns, and snaps.
The Reactor family features a more upright template with less rake, allowing for quicker direction changes and a more responsive, vertical approach to surfing. Ideal for surfers who like to stay in the pocket and perform tight, critical manoeuvres.
Performs particularly well in:
Performance Core (PC) fins are made using a multi-layered resin transfer moulding process. The flex pattern in PC fins extends progressively from the base through to the tip, helping the surfer to maintain drive and hold through a turn. This versatile fin material is light and can be used in a variety of different conditions.
