Firewire Surfboards and FCS have created the Firewire Shaper Series Performance Core Tri-Quad Fin Set. This lightweight performance fin is made from spliced veneer and uni directional carbon fiber built over FCS's small hex performance core. Branded with the Firewire logo burnt into the veneer and with a responsive tip flex and hydrodynamic foil on the side fins, this versatile template offers a balance of speed, drive and maneuverability.

Designed by Nev Hyman, the Firewire Tri-Quad (5 fin) template sits deep in the water and has minimal sweep, meaning it has great pivoting capabilities yet will hold nicely through turns. The smaller centre fin provides additional tail release.

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.
