Fin Control System History
The FCS (Fin Control System) is a type of surfboard fin setup that allows you to have interchangeable fins in your surfboard. The System was founded in late 1995 in Gold Coast (Queensland, Australia) and is still one of the most used Fin Control Systems after over 20 years. The idea is to have plugs underneath the surfboard that enables the surfer to use a set of screws to easily remove/add/replace a fin for storage or travel.The FCSII (Fin Control System Version Two) surfboard fins are the evolution of the FCS surfboard fins; the improvement consists of the ability to mount and unmount the fins without the need for any external tooling, and having a better drive, having the fins completely inside the surfboard.
The Future System is a single-tab system for surfboard fins. Each surfboard fin is secured with a single screw, and the fins are entirely inside the foam reduction.
Types of Surfboard Fins
- Single Fin: Classic and versatile, the single fin provides stability and control, especially for long rides and big turns. They are commonly used on single-fin longboards and single-fin shortboards.
- Twin Fins: These provide increased maneuverability and speed, making twin-fin surfboards a favourite for those looking for a playful experience.
- Tri or Thruster Fins: Featuring three fins, the thruster surfboard balances control and agility, making it a popular choice.
- Quad Fins:Quad or quad fin surfboards have four fins, offering speed in more giant waves and more hold in the water.
- Five Fin Surfboards: These offer the versatility to switch between quad and thruster setups, depending on the waves and your mood.
