FCS II Channel Islands Performance Core Tri-Fin Set
The FCS II CI PC Tri-Fin Set is a collaboration between FCS and Channel Islands Surfboards, one of the most celebrated shaping houses in the world. The result is a fin engineered to match the performance demands that Channel Islands boards are built around: powerful drive through the bottom turn, rapid release off the top, and responsive pivot when the wave demands a tight line.
Performance Core (PC) Construction
Performance Core is FCS's fiberglass composite construction. A woven fiberglass layup over a solid core gives the fin a lively, energetic flex that responds immediately to input from the surfer's back foot. The panel flex pattern is tuned to generate speed through turns rather than dissipating energy, making PC the go-to construction for powerful, committed surfing at an accessible price point relative to higher-end carbon options.
The fin face is smooth and consistent, with no voids or delamination risk that can affect cheaper injection-molded fins. The result is a fin that holds its shape and feel across an entire session and over years of use.
The CI Upright Template
Channel Islands worked with FCS to develop a template that reflects how Al Merrick and the CI team shape boards: a relatively upright, full-based outline that maximizes drive and hold through vertical maneuvers. The upright rake keeps the pivot point closer to the surfer's back foot, shortening the arc of the turn and making the board feel more responsive to deliberate, powerful surfing. Compared to more swept-back templates, the CI template rewards surfers who like to engage the fin early in a turn and drive hard through the exit.
FCS II Tool-Free Tab System
This set uses the FCS II plug system, which requires no tools and no screws for installation. Fins lock securely into FCS II-compatible fin boxes and release with a simple two-step motion. The connection is rigid under load, eliminating the flex and rattle that older screw-dependent systems could develop over time. The FCS II system is backward compatible with FCS I boxes when used with an adapter (sold separately).
Designed With and For the World's Best
FCS fins are developed in direct collaboration with professional surfers and shapers on tour. The CI partnership draws on Channel Islands' decades of experience building boards for world-title-level surfing, so the template is tested under real competitive conditions, not just modeled. Whether you surf Channel Islands boards or another high-performance shortboard that demands the CI fin geometry, this set delivers that proven feel.
Who This Fin Is For
The FCS II CI PC Tri-Fin Set is built for intermediate to advanced surfers who want a responsive, drive-oriented tri-fin setup. It suits punchy beach break and powerful reef conditions where generating speed through a bottom turn and snapping hard on the lip matters most. The PC construction hits a performance-to-value sweet spot: better feel than mass-market fins, more accessible than full carbon.

Frequently Asked Questions
- What does PC mean in the FCS II CI PC Tri-Fin Set?
- PC stands for Performance Core, FCS's fiberglass composite construction. It uses a woven fiberglass layup over a solid core to produce an energetic, responsive flex that drives speed through turns. It sits between entry-level injection-molded fins and premium full-carbon fins in performance and price.
- What is the CI (Channel Islands) fin template?
- The CI template is an upright, full-based outline developed in collaboration with Channel Islands Surfboards. The upright rake keeps the pivot point close to the surfer's back foot, producing fast, drive-oriented turns suited to powerful, committed surfing.
- Are FCS II fins tool-free?
- Yes. FCS II fins lock into compatible fin boxes without screws or a fin key. They install and release with a simple two-step motion, and the connection is rigid under load during a surf session.
- Do FCS II fins work in FCS I boxes?
- FCS II fins fit FCS I boxes when used with an FCS II-to-FCS-I adapter, which is sold separately. Without the adapter, FCS II fins require FCS II-compatible boxes.
- What kind of surfer and conditions is this fin set best for?
- The FCS II CI PC Tri-Fin Set is designed for intermediate to advanced surfers who prioritize drive, hold, and responsive pivot. It performs best in punchy beach break and powerful reef conditions where generating speed through a bottom turn and snapping hard on the lip are the priority.
- Is the FCS II CI PC Tri-Fin Set compatible with all surfboard brands?
- Yes. Any shortboard or performance board fitted with FCS II fin boxes can use this set. The CI template benefits surfers across board brands, not only Channel Islands boards.
- How does PC construction compare to FCS carbon fins?
- Performance Core uses a fiberglass layup that delivers lively, responsive flex at a more accessible price than FCS's carbon or carbon/glass hybrid constructions. Carbon fins are stiffer and lighter, which some advanced surfers prefer in larger surf. PC is the preferred choice for surfers who want performance feel with a broader flex range.
