FCS II Mayhem Fins

While the Mayhem template is engineered for critical, overhead conditions, it performs well in beach breaks that offer punchy, hollow sections. If you are surfing smaller, mushy waves, you might find a more upright, pivot-oriented fin template more effective.

The Performance Core Carbon construction makes these fins significantly stiffer than standard fiberglass or composite options. This rigidity provides immediate feedback and stability, which is essential for maintaining control during high-speed, explosive maneuvers.

No tools are required. The FCS II system is designed for a tool-less installation, allowing you to click the fins in and out of your board quickly, even right before you paddle out.

This template is built for surfers who prioritize aggressive, high-performance riding. It excels in the pocket, offering the drive and hold needed for tight, vertical turns and maintaining speed through fast, critical sections.

Yes, these fins are optimized for riders up to 200 lbs. If you exceed this weight, you may notice the fins feel slightly less stable or lack the necessary drive during hard turns.

These fins are specifically designed for the FCS II fin system and are not compatible with traditional dual-tab boxes that require grub screws. If you have an older board with original FCS boxes, you will need to use a different fin or install an adapter.
