Fins

Surfboard fins from the brands that shape how your board actually rides. Island Water Sports stocks FCS, Future Fins, Channel Islands, Endorfins and more, so you can dial in drive, hold and release for the waves you surf most. Whether you ride an FCS 2 or Futures box, we carry the set that fits.

Pick your setup by template and feel. We carry thruster sets like the FCS 2 Performer and Reactor, quad sets such as the Futures Controller, twin and twin+1 options like the FCS MR and Christenson, plus longboard, single and mid-length fins including the FCS 2 Mid and Connect. Constructions range from value-friendly Performance Glass (PG) to stiffer Performance Core (PC) and full carbon.

Are FCS 2 and Futures fins interchangeable?

No. FCS 2 fins click into FCS 2 boxes and Futures fins slide into Futures boxes. Check which system your board has before you order, and reach out if you want help matching.

How do I choose thruster, twin or quad?

Thrusters balance drive and control for most conditions, twins add speed and glide in smaller surf, and quads hold a line through faster, hollower waves. Your weight and board also matter, so size up or down by the maker's rider chart.
