Phase 5 Ahi Wakesurf Board - 2027
Designed by John Akerman, the 2027 Phase 5 Ahi brings an ocean-inspired feel to surf-style wakesurfing. Its moon tail, wide midsection, and rounded pin nose balance speed, drive, and control. The shape supports smooth release while maintaining momentum along the wave, and a Futures quad fin setup adds traction through powerful carves. Lightweight Flightlite V2 Pro Select construction complements the Ahi's focus on flowing turns and progressive surf-style riding.
Best For
- Surf-style riders: Riders seeking an ocean-inspired feel with flowing lines and responsive handling.
- Powerful carving: A Futures quad fin setup provides traction and drive through turns.
- Maintaining momentum: Tail shaping supports smooth release while carrying speed along the wave.
- Performance progression: Riders who prioritize low board weight and responsive feel as they develop their surfing.
Shape & Riding Performance
The Ahi's moon tail, wide midsection, and rounded pin nose work together to balance speed with control. Its outline channels water cleanly off the tail tips, allowing smooth release while preserving momentum. For riders, this makes flowing surf-style lines and linked turns central reasons to consider the Ahi.
The Futures quad fin configuration adds traction and drive through powerful carves. Phase 5 describes its quad setup as providing increased traction while retaining a loose, controlled riding character. This combination suits riders who want grip through turns alongside the ability to release the board during maneuvers.
Reflex Speedrail complements the shape with a refined rail profile engineered to enhance speed, responsiveness, and release through edge-to-edge transitions. It supports the Ahi's emphasis on moving smoothly between turns rather than simply cruising in one direction.
Flightlite V2 Pro Select Construction
Flightlite V2 Pro Select is Phase 5's lightest surf-style build, with a stated 20% weight reduction. Designed to emphasize performance and board feel, the layup includes full Innegra sheets on the top and bottom, a carbon stringer underneath, and carbon tape reinforcing the tail.
An ultralight EPS core and epoxy resin form the foundation of the construction. The Flexspine carbon stringer runs from nose to tail to enhance stiffness and overall board performance. V.R.T. technology uses a vacuum-assisted hand lamination process with built-in glass/bar stringers along the bottom edge for extra strength and pop.

Board Care
Avoid extreme heat and prolonged exposure to the elements. Phase 5 cautions that EPS foam melts at 150°F, making protection from excessive heat an important part of caring for this board.
