The Cluster, by Infinity Surfboards comes for the way the fins are “clustered” at the tail. The biggest fins are the 5.5” outside fins and the smallest fin is the 4” center fin. This is the opposite of the average long board, but the concept has proven a favorite for thousands of surfers for fast, powerful turns. The big outside fins create the drive and projection when you turn and the small center fin is just a stabilizer that removes that “squirrelly” feel that twin fins have. The Cluster model excels in carving and turning. We make it with a little more “kick” in the nose for more aggressive, vertical surfing, however, it is also a favorite for beginners because it is easier to turn and easier to ride.
