FCS II Channel Islands AM Surfboard Fins

The Channel Islands AM template is designed for versatility. It excels in a wide range of conditions, from punchy beach breaks where you need quick, snappy turns to open-face waves that require reliable hold and drive.

Performance Core construction uses a resin transfer molding process that creates a lightweight fin with a consistent, responsive flex pattern. This gives you a lively feel that loads up and releases energy through turns, making the board feel more reactive than standard glass-on or solid fiberglass fins.

No, these use the FCS II system, which is designed for tool-less installation. You simply insert the front of the fin base into the plug and press down until it clicks into place.

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.

The Small size is generally recommended for surfers weighing between 55kg and 70kg (120lbs - 155lbs). If you are on the heavier side of that range and prefer a looser feel, this size will work, but you may want to consider a Medium if you prioritize extra drive.
