Phase Five AHI 53" Wakesurf Board
The 2026 Phase Five Ahi is a performance surf style wakesurf board designed by John Akerman for riders who want a true ocean-inspired surf feel behind the boat. Phase Five says the Ahi features a moon tail shape, wide midsection, and fully rounded pin nose for a strong blend of handling and performance.

That second sentence is an inference based on the official shape description and fin configuration.
