A single fin designed for smooth, controlled, flowing turns.
The Flow fin is a single fin 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.
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.
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. Its higher sweep and elongated base make it perfect for surfers looking to draw longer lines and maintain fluid style.
Machine-cut from layers of solid fibreglass, Performance Glass fins share the same flex pattern and material feel as traditional fibreglass fins - a stiff base with subtle, responsive tip flex. Proven durability and clean aesthetics make these a favourite among pro-level surfers, especially where flex integrity needs to hold up under extreme force and conditions. A natural transition fin for surfers moving from fixed fins to the FCS system.
