FCS II Mark Richards Twin + Stabiliser Fins

These fins are designed primarily for fish, hybrid shapes, and funboards. They excel on boards that need the loose, fast feel of a twin-fin but require a bit more stability and control in the pocket.

The center trailer acts as a pivot point, adding control and hold through turns. While you still get the speed and freedom of a twin-fin, the stabilizer prevents the tail from sliding out too easily, making the board feel more predictable in steeper waves.

No, these are FCS II fins, which are designed for the tool-less FCS II fin system. While they can be used in older dual-tab boxes with grub screws, they are optimized for the click-in, click-out convenience of the FCS II system.

Performance Core construction uses a multi-layered resin transfer molding process to create a progressive flex pattern. This means the fin is stiffer at the base for drive and gets progressively more flexible toward the tip, providing a snappy, responsive feel that adapts to your turns.

Yes, you can remove the center stabilizer if you want to experience a looser, more traditional twin-fin feel. However, the set is specifically engineered to work as a trio, so expect a significant increase in looseness and a decrease in drive if you ride them without the trailer.
