The Phase Five Ahi designed by John Akerman is a complete “ocean” style surfboard that delivers true wakesurf performance. The design features a moon tail shape, wide midsection and a fully rounded pin nose for a perfect blend of handling and performance. The Ahi’s outline delivers more speed and drive down the line while channeling water flow off the tips of its tail for optimal release. The Ahi Stealth is glassed with the Stealth™ layup which features a Basalt/Innegra weave to provide an ultra-strong and responsive board. It is equipped with a quad FCS Fusion fin setup.
