FCS II Flow II PG Longboard Fin – Mango

The FCS II Flow II PG Longboard Fin in Mango is a performance-focused single fin designed for surfers looking for drive, hold and smooth, powerful turns from their longboard.

With a more raked template than an upright traditional logging fin, the Flow II is designed to maintain speed and control through longer carving turns. The combination of rake, refined tip and Performance Glass construction makes it particularly well suited to performance longboards and surfers who enjoy turning their board from the tail.

Raked Longboard Fin for Drive & Flow

The defining characteristic of the FCS Flow II is its raked outline.

Additional sweep allows the fin to generate drive through longer turns while maintaining a smooth connection between manoeuvres. This makes the Flow II a great option for surfers looking to draw flowing bottom turns, carves and longer rail-to-rail arcs rather than the tighter pivoting feel of a more upright fin.

The template also provides dependable hold when the board is travelling at speed, giving you confidence to push harder through turns.

Performance Glass Construction

The Flow II is constructed from FCS Performance Glass (PG).

Performance Glass fins are made from layers of solid fibreglass, producing a stiff, responsive fin with controlled flex under load. This provides a solid connection between the surfer and board and helps translate pressure through the fin into drive and acceleration.

For a performance-oriented longboard single fin, the combination of a raked template and Performance Glass construction delivers a responsive and controlled feel.

Designed for Performance Longboarding

The FCS II Flow II PG is particularly well suited to longboards designed to be surfed dynamically from the tail.

Its combination of rake, drive and hold allows you to push through bottom turns, carving turns and faster sections, while maintaining a smooth, flowing feel as you transition between manoeuvres.

It's an excellent option for surfers who want their longboard to feel responsive without sacrificing the stability and control provided by a full-size single fin.

FCS II Tool-Less Longboard System

The Flow II uses the FCS II Tool-Less Longboard System, eliminating the need for a traditional screw, plate or fin key.

The fin can be quickly installed, removed or repositioned within the longboard fin box, making it easy to experiment with fin placement and adjust the performance of your board.

Move the fin slightly forward for a looser, more responsive feel or further back when you want additional hold and control.

Mango Colourway

Finished in the distinctive Mango colourway, this version of the Flow II combines its clean, performance-focused template with a bright contemporary finish.

Perfect For

Performance longboards, all-round longboards, single-fin surfboards, powerful bottom turns, carving, faster waves, flowing rail-to-rail surfing and longboarders who prefer a more performance-oriented feel.

Why You'll Love It

The FCS II Flow II PG Longboard Fin in Mango is a strong choice if you want your longboard to turn with drive and flow rather than pivot sharply around the fin.

Its raked template helps maintain momentum through longer turns, while Performance Glass construction provides the responsive feel and control needed when pushing harder through the tail.

Combined with the convenience of the FCS II tool-less system, the Flow II is a premium longboard fin for surfers looking to blend traditional single-fin flow with more powerful, performance-oriented surfing.
