FCS Al Merrick Air Core Fin

No, these fins are designed exclusively for the FCS II fin system. They are a tool-less, click-in design and will not work with older surfboard boxes that require screws or plates.

The AirCore construction uses a lightweight, pressed polyurethane foam core that reduces the overall weight of the fin. This makes the board feel more responsive and lively under your feet, allowing for quicker transitions and easier maneuverability.

This template is engineered for progressive, high-performance surfing. The raked side fins provide the drive needed for speed, while the smaller center fin allows you to break traction easily for tight, aggressive turns and snaps.

Size Small is generally recommended for lighter surfers, typically weighing between 55kg and 70kg (120lbs to 155lbs). If you fall outside this weight range, you may find the fins feel either too loose or too stiff for your board.

Absolutely. While they excel in high-performance conditions, the drive generated by the raked side fins makes them versatile enough to handle a variety of wave types, provided you are looking for a responsive, loose feel.
