AHI TWIN FIN SET
The AHI Twin Fin Set is a unique performance twin designed by Duke Aipa specifically for the AIPA Dark Twinn. With its wide base, upright profile, refined tip, and 6° cant, the AHI stands apart from traditional twin-fin templates—bringing a different balance of speed, drive, release, and maneuverability to the twin-fin experience.
The wide base provides the drive and acceleration you expect from a twin, while the upright profile allows the board to pivot and transition quickly from rail to rail without the drawn-out feeling of a more traditional raked twin fin.
The result is a setup that feels fast, fluid, and responsive—with plenty of drive through turns, but enough release to keep the board loose and maneuverable. The AHI twins are designed to be ridden standalone as a true twin-fin setup, while the included trailer fin gives surfers the option to add a little more stability, hold, and comfort when they want it—without taking away the speed and freedom of the twin-fin feel.
Originally developed for the Dark Twinn, the AHI is also a go-to fin for the STEP TWIN, and works naturally with other high-performance twins and twinnies looking for a more upright, performance-oriented approach.
Built by NVS in G10 construction.
