All the boards come with the “Power Box” fin system in combination with the 2 side slot box to allow to find the best trim of the board: single fin for freeride or freestyle oriented sessions, thruster fins for more grip and ease on waves.
The 78lts, 84lts and 90 lts are equipped with K4 for RRD 3SW center and SHARK 2 side while the bigger sizes (the 96lts, 104lts and 114 lts) come with a single K4 for RRD 3SW.
