2026 Phase Five Boards Ahi Stealth 50 in

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 our 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.

The Stealth construction is our newest surf style build that introduces basalt into our lineup. This layup schedule includes a full basalt/innegra top weave reinforced with a carbon stringer and tail patches. The bottom is a full Innegra sheet reinforced with a carbon stringer. It is the strongest layup schedule that we have to date in the lineup and it doesn’t sacrifice any performance. The Stealth build provides great pop and a lively feel under the rider’s feet. This build is only offered on our top “Performance” shapes.
