The FCS Flow III Screw & Plate PG Single Fin is designed for smooth, controlled, flowing turns and classic longboard performance. Inspired by the iconic designs of George Greenough, this refined template suits surfers who prefer a more relaxed, flowing approach to longboarding. With an elongated base for strong drive and a long curved tip for controlled turning, the Flow fin delivers smooth rail-to-rail transitions while maintaining the trim stability needed for extended nose rides. Compatible with all longboards using the Screw & Plate System.

Performance Glass (PG)
Performance Glass (PG) fins are machine cut from layers of solid fiberglass. These fins are stiff, and are widely used by pro level surfers because the integrity of the flex is maintained under immense force, and in the most extreme of conditions and situations.
Additional Info
Performance Feel
The Flow fin is designed for smooth, stylish longboarding with controlled turning arcs. The wide base provides strong drive off the bottom, allowing surfers to generate speed and maintain flow through turns. Its higher sweep and curved outline promote long, drawn-out carving lines, while the thin tapered tip improves sensitivity when transitioning from rail to rail. The result is a fin that feels stable when trimming, responsive during turns, and perfectly suited to flowing longboard lines, while still providing the stability needed for extended nose time.
Fin Template: Connect
Drive, flow, and smooth turning control. The Flow template is designed for surfers who want a single fin that emphasizes smooth carving turns, trim stability, and classic longboard flow.
