Simon Anderson's FCS II SA PC Tri-Quad Fin Set complements any style shortboard in intense surf where you want equal parts drive and release. Best suited to high performance surfing, the SA PC Fins help maintain speed and control through turns, giving you the confidence and ability to remain focused on the next critical section. Give yourself options by using it as a thruster, a quad or even a twin to mix and match the fin set-up with wave types and conditions.

The FCS II system has been designed to perform at the highest level by seamlessly connecting 3 essential elements in surfing; the surfer, the surfboard and the fins. When paired with fins from the new FCS II Essential Series, it’s now possible to install and remove your fins in seconds, without the need for any screws or tools.

What you’ll find when you ride the new FCS II system is more speed, more drive, more acceleration, and most importantly more response from your board. This equates to better surfing, and you’ll be in the line up faster.

Our team riders have given the new FCS II system their personal tick of approval, which is validation from the best surfers on the planet.

  1. Keyless: Efficient keyless system for quick fin installation and release.
  2. Flush Leading Edge: Recessed leading edge with flush base connection improves water flow.
  3. Backward Compatible: Grub screws can be inserted to accept your existing FCS fins.
  4. Mechanism: Rotating Barrel: Self lubricating, wear resistant barrel locks the fin into the plug.
  5. Mechanism: Titanium Rod: Aerospace grade titanium rod applies lateral pressure to the fin tab.
  6. Honeycomb Construction: Lightweight composite frame encapsulated by high density foam reduces weight and maintains tail flex.
