Surfboard Fin Systems

FCS Fins and Futures Fins are the leading brands in the market today who manufacture Surfboard Fins and Surfboard Fin Systems. At present, there are 3 main fin systems (fin boxes) that can be selected when purchasing a new custom surfboard. They are FCS, FCS II and Futures fin systems (fin boxes).

FCS II fin boxes will only accommodate fins with the FCS or FCS II fin technology systems. FCS II Compatibility kits can be purchased to ensure that your older model FCS fins can be used in the new FCS II fin system.

Futures fins boxes will also only accommodate fins with the Futures fin technology system.

There are many different board companies that use both FCS II and Futures fin systems.
