With enhanced speed, lift, drive and stability, the 3D will take the performance of your standard thruster set up to a new dimension. It harnesses FCS's innovative construction technology and offers a new dimension in performance. Because the fin's unique tip is parallel to the board's surface, the 3D holds speed during on-rail surfing where traditional fins can pop or stall, delivering extra squirt in the second half of your turns. The tip also increases lift and stability, helping you glide over flat sections and increasing control in broken water.
