Five fin sets offer versatile performance for surfers and riders alike by combining elements of both thruster and quad setups. This configuration includes two side fins, two rear fins, and a center trailer fin, giving riders the ability to adapt their board to various conditions. Five fin boxes don’t mean you ride all five at once—instead, they give you the flexibility to switch between setups like a thruster for tight, pivoty turns, or a quad for speed and hold down the line.
