The FCS II Al Merrick Medium PG Pro Tri Fin Set is built for radical, progressive surfing and designed to match the high-performance demands of the world's best surfers. This signature template by Al Merrick delivers a powerful combination of speed, drive, and precision control—ideal for deep carves and explosive maneuvers in hollow, fast-breaking waves.
Featuring raked side fins for down-the-line speed and hold, the medium-size set also includes a smaller center fin that enables quicker tail release through turns. This creates the perfect balance between drawn-out power and reactive control, making this fin set a go-to for surfers who love aggressive turns and quick transitions.
Crafted using Performance Glass (PG) construction, these fins are machine-cut from solid fiberglass layers, offering pro-level stiffness, durability, and extremely fast memory response. PG fins maintain flex integrity under high pressure, making them the trusted choice for advanced surfers charging in heavy, demanding conditions.
Best suited for performance shortboards with deep concaves and moderate-to-extreme rocker profiles, this fin set excels in steep, punchy surf where power and control are non-negotiable.
