FCS II AM PC Fins

The X-Small size is specifically designed for lighter surfers, typically weighing under 120 lbs (55 kg). This sizing ensures the fin has the correct surface area to provide control without feeling too stiff or overwhelming for smaller riders.

The AM stands for Al Merrick, the legendary shaper behind Channel Islands Surfboards. These fins feature a signature raked template that prioritizes speed and drive, allowing for longer, more drawn-out turns while maintaining responsiveness.

No, these use the FCS II system, which is designed for tool-less installation. You simply click the fins into the fin box by hand, and they are secured by a tension mechanism.

Performance Core construction uses a resin transfer molding process that creates a lightweight fin with a consistent, progressive flex pattern. This gives you a lively feel that helps with maneuverability and speed generation in various wave conditions.

Yes, FCS II fins are backward compatible with original FCS dual-tab plugs. However, you will need to use grub screws to secure them, as the click-in mechanism only functions with FCS II boxes.
