FCS II MB

This fin is built for power surfing. Its wide base and stiff construction are engineered to hold speed through long, drawn-out rail carves and provide stability when you are pushing hard through critical sections of a wave.

The PC AirCore construction uses a lightweight foam core wrapped in fiberglass and carbon. This makes the fin significantly stiffer and more responsive than standard molded fins, giving you a more immediate, snappy feel when you initiate turns.

Yes, the MB PC Carbon is designed as a tri-quad set. You can run them as a thruster for a more traditional, pivot-heavy feel, or as a quad setup if you want more speed and hold on open-face waves.

These are generally better suited for intermediate to advanced surfers. The stiff, high-performance flex pattern requires a certain level of technique to engage properly; beginners often find a more flexible, forgiving fin easier to learn on.

They work best on performance shortboards and hybrid models that have a bit more rocker. Because the template is designed for power and drive, it helps compensate for the extra curve in high-rocker boards, keeping your speed up in the pocket.

The MB PC Carbon is recommended for riders up to 200 lbs. If you exceed this weight, you may find the fin flexes too much under heavy pressure, which can lead to a loss of drive and control.
