The longboard fin box adapter by FCS allows you to change from a traditional
longboard center fin to an FCS thruster set up in seconds. The reason you need
an adapter is that the center fin box on stand up paddle boards is a different
type of box than the side FCS compatible fin boxes. An SUP thruster fin set-up
doesnt use a traditional longboard fin in the center box, but rather
three similar size FCS compatible fins in a three fin configuration. The thruster
set-up is preferred by many of the top surfing pros. Its a great fin
set-up for loosening up your high-performance stand up paddle surfing board.
The adapter is adjustable for deeper longboard center fin boxes.
Included in the Adapter Package:
- One box adaptor insert
- One stainless steel plate
- One short screw
FCS, which is an acronym for Fin Control System, is the pioneering
company in removable fin systems. Before the 1990s, most surfboard fins were
an inseparable component of a surfboard. The fins were glassed right to the
board. There were removable fins as far back as the 1960s, but it wasnt
that common and there was no standardization so things werent really
interchangeable. So to a larger degree, whoever was manufacturing the board
was also making the decision about fin configuration and fin selection. FCS
came along in the early 1990s and separated these three pieces by creating and
popularizing a standardized FCS fin box. Suddenly board manufacturing and fin
choice and fin configuration selection were largely separated.
FCSs standardization of fin boxes made removable fins commonplace. This
changed a number of things. First off, it allowed for massive advances in fin
design and performance as companies were tinkering with new materials and various
designs. Secondly, it allowed surfers to use one surfboard (the control factor
in this experimentation) and change their fin configuration to find out what
they liked best. They could even use different configurations for different
conditions. Lastly, it made surfboards far easier to transport with the fins
removed, which was no trivial event. Manufacturers and retailers were able to
store and transport boards much easier, and with much less risk of breakage.
In large part due to FCS, the variety of fins available is almost overwhelming
and surfing performance has made great strides. The market for SUP fins is really
just in its infancy (as R&D production cycles can be years in the fin industry),
but be sure that FCS fins will be at or near the forefront of what is to come
in the advance of SUP fin design.
