FCS II MF Twin+1 M-L Black Keel

The FCS II MF Twin+1 M-L Black Twin Fin was developed in partnership with Mick Fanning to deliver speed, control, and power on twin fin boards. With a central stabilizer included, it offers greater security in turns and increased versatility for surfers seeking performance with fluidity.

Overview

The FCS II MF Twin+1 M-L Black is a high-performance fin designed for surfers who want the speed and freedom of a twin fin, but with the added control of a central stabilizer. The Twin+1 set combines two larger side fins with a smaller central fin, delivering a loose, fast, and at the same time more secure feel during maneuvers.

Developed in collaboration with Mick Fanning, three-time world surf champion, this fin blends modern performance elements with the classic fluidity of twin fins. It’s an excellent option for those seeking acceleration, drive, and control on fish boards, funboards, and twin fin models compatible with the FCS II system.

About the FCS II MF Twin+1 Fin

The Mick Fanning Twin+1 line was created to offer a more refined twin fin, focusing on speed, power, and control. Its design was inspired by high-performance FCS templates, resulting in a fin with quick response, good projection, and stability in turns.

The side fins provide plenty of drive and speed down the line, while the central stabilizer fin helps to better control the board in carves, cutbacks, and maneuvers with more pressure. This makes the set more versatile than a traditional twin fin, especially for surfers who want to surf fast without sacrificing security.
