The Aku Wakesurfer was the first surf style board introduced by Phase Five. This is a fast, rail to rail, air boosting machine. The Phase Five Aku features a diamond bumped wing tail for optimum pivot and pop. It harnesses a nicely pulled in nose that enables aggressive carving on the wave without nose diving. The Aku is glassed with our high end FLEXtec V2 system for unmatched strength and durability. It is built with FCS Fusion fin plugs in a twin fin configuration for an optimal blend of maneuverability and drive.
