FCS II Flow III PG Longboard Fin – Cacao

Draw smooth lines and flowing turns with the FCS II Flow III PG Longboard Fin in Cacao. Inspired by classic longboard fin templates, the Flow III is designed for surfers looking for a combination of strong drive, controlled carving and stable trim.

The wide, elongated base generates drive off the bottom and helps maintain speed through longer turns, while the swept outline encourages smooth, drawn-out carving lines. A tapered tip adds sensitivity through rail-to-rail transitions, creating a fin that feels stable when trimming yet responsive when you want to turn.

Constructed from Performance Glass (PG), the Flow III delivers a stiff, dependable flex pattern that maintains its integrity under load. This provides a direct and controlled feel through turns, with the drive and stability suited to both classic and modern longboard surfing.

The FCS II tool-less longboard system allows the fin to be installed, removed and repositioned without a traditional screw and plate. Moving the fin forward or back in the fin box also allows you to fine-tune the balance between manoeuvrability, drive and hold.

Available at FlowState Surf & Sport in two sizes, allowing you to choose the Flow III that best suits your longboard, surfing style and preferred balance of hold and response.
