FCS Fluid Foils Longboard Fin

The Fat Boy is designed for standard longboard boxes. As long as your board has a traditional center fin box, this fin will slide in and secure with a standard fin plate and screw.

An 8-inch depth provides a balanced profile that offers enough hold for stability without feeling overly stiff. It is a versatile size that works well for most traditional longboards, offering a predictable feel in a wide range of wave conditions.

This fin is optimized for both. Its shape is specifically engineered to provide the hold needed to keep you steady on the nose, while still allowing for smooth, drawn-out turns that are characteristic of traditional longboarding.

The Fat Boy is built to balance durability with specific flex characteristics. It is stiff enough to provide the stability required for nose riding, but it retains just enough flex to keep your turns feeling responsive rather than rigid.

It is designed for traditional longboarding. If you prefer a classic, smooth style of surfing—focusing on trim, glide, and nose riding rather than aggressive, high-performance maneuvers—this fin will complement that approach perfectly.
