The Summer vibes Quad Keel 4-Fin Set – FCii (Blue) is built for surfers who want maximum speed, bite and hold without losing that smooth, flowing twin-keel feel. With a 5-inch front keel and a 3-inch quad rear trailer, this set creates the perfect blend of drive, control and playful release—ideal for fish shapes, hybrids and modern quad boards in fun Aussie waves.
Designed with premium fibreglass construction for stiffness, durability and predictable flex, these fins slot cleanly into fcs-2-style fin boxes. The result is a rock-solid fit, excellent power transfer, and a fast, responsive feel under your feet.
