The Aku is the very first surfboard shape introduced by Phase Five. This is a fast, rail to rail, air boosting machine built for speed. It features a Twin fin FCS surf style setup for maximum speed and drive. Pair the fin set up with a diamond bumped wing tail for optimum pivot and pop. For 2022, the Aku V2 is built using our tried and true FLEXtec V2 construction bringing the durability and performance to another level!
