Quattro Chamäleon Quad Concave Asymmetrical Windsurfing Fins 100% Carbon Fin sizes (cm): 24 28 32 Sail size (m2): 5.5 6.5 > 6.5 This fin represented a milestone in fin design. It makes sailing at the very limits easier than ever before. Although one can sail modern sails in unbelievable wind strengths, the fin will often limit the top end potential by tailwalking and spinning out in choppy water. Even though you could go faster, you have to slow down to regain control. With the Quattro Chamäleon, you can push the board into a new gear without having to worry about control. It will transform your board into a totally different kind of beast. The Quattro Chamäleon points remarkably high for a weed fin, allowing you to quickly return upwind after a speedy broad reach downwind.
