The FCS CI Keel PG Large Twin Fins are Al Merrick's performance keel twin set — designed for the Channel Islands Fish Beard model and purpose-built for surfers who want speed, flow, and progressive power from a true performance keel. A modern keel template combined with a progressive flex pattern delivers the kind of control and speed that separates the CI Keel from traditional, flow-only keel designs.

• Template: Modern CI performance keel — designed by Al Merrick specifically for the Fish Beard model; focus on speed and flow
• Construction: Performance Glass (PG) — woven fiberglass with a progressive flex for a lively, responsive feel
• Foil: Progressive flex foil — provides excellent control for power surfing while maintaining the classic keel speed and trim feel
• Size: Large — designed for the Fish Beard and similar high-performance fish shapes
• Board Compatibility: Fish, funboard, and twin fin boards — recommended for FCS II boards
• Fin System: FCS II — tool-free installation
• Sold as: A pair (left + right)

Sizing Note: CI Keel PG Large is designed for performance fish shapes. Best matched with the CI Fish Beard or similar large twin fin designs. Confirm FCS II twin fin box configuration before ordering.

Care: Rinse in fresh water after each use. Store in a fin wallet to protect keel edges between sessions.
