Our Tower boards only
ship with a single center fin, no matter what fin box configuration they're built with. We do this because the majority of riders will not need to purchase side fins. We install
the side fin boxes to give you flexibility in how you use your board--lake, ocean, surf, river, etc. Side fins are used primarily for inceasing maneuverability when surfing or increasing tracking for heavier riders. We do also make boards that simply have traditional longboard fin setup (just the center fin) and can be used in surf but don't need side fins.
If you find your board is snaking back and forth
more than you like in the water (where you're having
to switch paddling sides more often than you like),
you can correct this to a large degree with the
fin side and configuration. The tracking can all be corrected
with a change in fins, and there are really two
ways to correct it. The most common is to replace the center fin
with a big rudder-like fin. The second option is to add two small
side fins (called side bites). On our Tower boards
we use Futures Fins boxes (by design, they're a
much better mounting solution on thick SUP boards)
