George Greenough is often solely credited for launching the modern surf fin movement. He modeled his templates from the leading edge and swept-back rake of the dolphin fin, revolutionizing fin dynamics, firmly embedding Greenough's work into the DNA of modern surfing. The 4-A is the yard stick of performance longboarding, while earning its way into the mid-range and shorter length single fin favorite.
Try this solo in a 9ft Ultimate, 9'5 Analog, or 9'2 Ladle for tons of maneuverability and flow. Ask about smaller sizes for custom single fin applications.
*The Volan version of the 4-A is as good as it gets. The flex pattern is uniform throughout the fin, not just a flexible tip. Hand-made in Goleta, CA., this is the cream of the crop.
