FCS Al Merrick PC Large Grey Thruster Fins — Channel Islands shaper-tuned template for powerful overhead surfing.

Al Merrick's signature thruster template has shaped the FCS lineup for decades — and for good reason. The AM Large in Performance Core polycarbonate is designed for surfers 185+ lbs who want the raked side fins' exceptional speed and drive paired with quick release through the center. Built for steep, hollow beach breaks and punchy overhead conditions where the board needs to accelerate hard off the bottom and unload off the lip.

• Template: Al Merrick — raked side fins for speed and drive, smaller center fin for tail release
• Size: Large — recommended for surfers 185+ lbs
• Construction: Performance Core (PC) — injected polycarbonate with consistent, stiff flex
• Color: Grey
• System: FCS II compatible — tool-free installation
• Set includes: Left, right, and center fin

The AM template sits in FCS's Carver family — drive-oriented fins that power through turns and maintain speed down the line. At Large size, the raked template gives bigger surfers the surface area they need to hold rail through critical bottom turns without losing the pivot to snap off the top.

Fit Note: FCS II tool-free tab system. Confirm your board has FCS II fin boxes before ordering.

Care: Rinse with fresh water after use. Store in a fin bag to prevent edge damage between sessions.
