The FCS Al Merrick PC Twin+1 XL Fins bring Channel Islands' shaping philosophy into fin design — a collaboration template tuned for Al Merrick's board outlines, in PC (Performance Core) construction, for surfers who want speed, drive, and versatility from a twin+1 setup.

Key Features:

• Al Merrick Signature Template — designed in collaboration with legendary shaper Al Merrick to complement Channel Islands board outlines; balanced between projection and pivot with a rake optimized for CI's typical mid-tail widths
• Twin+1 Configuration — includes two side fins plus a center trailer fin; run as a twin for maximum speed and looseness, or drop in the trailer for added hold and drive in overhead conditions
• Performance Core (PC) Construction — honeycomb core wrapped in fiberglass delivers a light, lively flex pattern with more response than standard fiberglass; slightly softer than carbon, providing excellent feel feedback through turns
• XL Size — larger template suited for surfers 190 lbs+ or surfers who prefer maximum drive in powerful conditions regardless of their weight
• FCS II Compatibility — tool-free snap-in installation for FCS II fin boxes; no fin key required

The twin+1 setup is one of the most versatile configurations in surfing — it gives you the pure speed and skate of a twin with the option to add the trailer fin when conditions demand more hold. Al Merrick's template input means these fins are particularly well-dialed for Channel Islands boards, though they work equally well in any FCS II-compatible board with mid-width tail dimensions.

Sizing Guide: XL recommended for surfers 190 lbs and above. Heavier surfers or those surfing powerful waves will benefit most from the XL's additional drive.

Compatibility: FCS II fin system only. Sold as a complete 3-fin twin+1 set.
