Pure Performance Longboard Fin
On pure performance longboards, the goal is to rip airs, 360s, and huge snaps, and even ride deep in the barrel—similar to how you’d surf a shortboard. Because the emphasis is on aggressive turns rather than noserides, a longer center fin is actually a hindrance instead of an advantage.
Thus, pure performance longboards will often have a 2+1 set up with a shorter, cutaway center fin (typically in the 6- to the 7.5-inch range) and standard side fins. Even further along the performance spectrum is a longboard with a thruster setup featuring standard, 4.5-inch fins both on the sides and in the center, such as Kanoa Dahlin’s K2D2 or the Hawaiian South Shore HP model. These configurations will tend to spin out when noseriding through technical sections, but they allow for cutting-edge, high-pro shredding, even on a longboard.
