FCS

FCS & FCS II Fin system with more WSL titles than any other fin manufacturer

In the early 1990s, a man by the name of Brian Whitty approached three local surfers from the Northern Beaches of Sydney with a brainwave: removable surfboard fins... an alternative to glassed-in fins.

Removable fins would make travelling easier, allow surfers to change their fin setup to suit varying conditions, and, more importantly, allow them to change the performance of their surfboard simply by using a different fin template. Over the next few months, Whitty's ideas were transformed, and FCS Fins was born. To this day, FCS is the strongest, most successful, and also the most widely used fin system in the world. Made from performance core carbon, performance glass and exceptional drive in both their thruster and quad range, these fins are the most sought-after fins on the market and ideal for performance surfing.

FAQs

What is the difference between FCS I and FCS II fins?

The difference between the FCS fin range FCS I and FCS II mainly lies in the fin attachment system and how easily you can install or remove the fins:

FCS I (Fin Control System 1)

Requires screws: You need a fin key to tighten small grub screws that hold the fins in place.
Single tab system: Fins have two tabs (front and back) that slide in easily.
Reliable and secure, but it takes a bit longer to take off the fins.

FCS II

Tool-less system: No screws or fin key needed – just push the fins in and they click into place.
Dual tab design with a special locking mechanism inside the fin box.
Quicker and more convenient – ideal for travel and easy fin swaps. Cuts the fin set-up time in half.
FCS II plugs are backward compatible – you can use FCS I fins in an FCS II box with grub screws and a tab infill kit.

Are Futures or FCS fins better?

Futures and FCS are the two leading surfboard fin systems in the fin family, each with its strengths. Futures fins use a single-tab base that’s screwed in for a solid, locked-in feel and excellent energy transfer, making them a favourite among surfers who want strength and performance, especially in powerful waves.

FCS, on the other hand, offers two systems: the original FCS I with dual tabs and screws, and the FCS II system, which allows for tool-free, quick fin changes—great for convenience, speed and travel. FCS fins are widely available, offer a huge range of templates, and are often more user-friendly for casual surfers. In contrast, Futures are known for durability, control, acceleration, and a more connected grip feel underfoot. Ultimately, the better option that is suited for you depends on your surf style, preference for ease versus performance, and what system your board is already set up for.
