Al Merrick's High-Performance Fin Template in FCS II
The FCS 2 AM PC Tri-Quad Fin Set is built around Al Merrick's proven shaper template, one of the most trusted fin designs in progressive, high-performance surfing. The raked side fins generate exceptional speed and drive down the line, while the smaller centre fin on this template delivers quick release through critical turns. Together, the geometry pushes power through your rail and snaps the board free exactly when you need it.
This is a 5-fin Tri/Quad set, giving you the flexibility to run a thruster configuration for tight, pivoting turns or a quad setup for open-face drive and additional speed in hollow, punchy surf.
Performance Core (PC) Construction
The AM PC fins are built with FCS's Performance Core material: a fibreglass layup over a honeycomb core that balances stiffness and flex in a way that raw fibreglass alone cannot match. The result is a fin that transmits energy from your turns into the water efficiently, with enough flex tip to keep the ride lively rather than rigid. The construction is lighter than solid glass and more responsive than many composite alternatives, making it a strong all-around choice for dedicated surfers who want a step up from entry-level materials without moving into full carbon.
Fin Family: Carver
The AM template belongs to FCS's Carver family, characterised by powerful, drawn-out turns with added hold. This is not a pivot-style fin. It is built for surfers who generate speed through committed rail-to-rail surfing and want their fins to hold through the arc, not spin out. At the same time, the raked template keeps the release point honest so you are not locked in when you want to break free.
Ideal Conditions and Board Match
These fins are optimised for hollow, steep waves and punchy beach breaks where speed and precise drive matter most. They are designed for performance boards with deep concaves and moderate-to-extreme rocker, the kinds of shapes that reward committed, radical surfing. The FCS II tab base fits all FCS II fin boxes without tools, snapping in and out cleanly for quick configuration changes on the beach.
Configuration Flexibility
The 5-fin set supports both Tri and Quad configurations:
- Tri (Thruster): Use the two side fins and the centre fin for pivoting, balanced control in powerful surf.
- Quad: Drop the centre fin and run all four side fins for additional speed and down-the-line drive in fast, hollow waves.
Switching between setups takes seconds with the FCS II toolless system, so you can dial the board to the conditions on any given day.
FCS II Compatibility
These fins fit the FCS II fin system, which is the most widely used fin box system on performance shortboards. No fin key required. The tab base locks securely under paddling loads and releases cleanly when you pull the tab. If your board runs FCS II boxes, these fins drop straight in.

Frequently Asked Questions
- What is the difference between the Tri and Quad configuration in this fin set?
- Running Tri (thruster) uses the two side fins and the centre fin, delivering balanced control and pivot in powerful surf. Running Quad removes the centre fin and uses all four side fins, increasing speed and down-the-line drive in fast, hollow waves. This set includes fins for both setups so you can switch on the beach without buying additional fins.
- What does PC (Performance Core) construction mean for FCS fins?
- Performance Core (PC) is FCS's fibreglass-over-honeycomb-core construction. The honeycomb reduces weight compared to solid fibreglass while maintaining stiffness through the base and allowing controlled flex through the tip. It is a step up from FCS's entry-level materials and sits below full carbon in the performance range.
- Are FCS 2 AM fins compatible with my board?
- These fins fit any board with FCS II fin boxes. FCS II is a toolless system: the tab base snaps in and locks without a fin key. If your board has FCS II boxes, these fins are a direct fit. They are not compatible with the original FCS (non-II) single-tab system without an adapter.
- What type of surfing and waves are the FCS 2 AM fins designed for?
- The AM template is built for radical, progressive surfing on hollow, steep, and punchy beach break waves. The raked side fins deliver speed and drive, while the smaller centre fin provides quick release through critical turns. The fins perform best on performance shortboards with deep concaves and moderate-to-extreme rocker.
- What is the Al Merrick fin template?
- Al Merrick is one of the most celebrated surfboard shapers in the world and the founder of Channel Islands Surfboards. His AM fin template is a raked, drive-oriented design built for progressive, high-performance surfing. FCS developed the template in collaboration with Merrick and the world's leading surf athletes.
- Can I buy the FCS 2 AM PC Tri-Quad fins at Island Water Sports?
- Yes. The FCS 2 AM PC Tri-Quad Fin Set is available at Island Water Sports in South Florida and online at islandwatersports.com.
- How many fins are included in this set?
- This set includes 5 fins total: two side fins, one centre fin, and two quad rear fins. That gives you everything needed to run either a thruster (Tri) or a quad configuration with the same set of fins.
