Add to CartThe 2027 Phase 5 Doctor gives experienced wakesurfers a stable surf-style platform for advancing their riding. Its wide, parallel outline supports trick progression, while the single-concave bottom and rocker help carry speed along the wave. Quad fins provide drive and grip through turns. With three sizes offering suggested weight limits up to 275 pounds, the Doctor suits bigger riders seeking stability alongside performance-focused handling.
The Doctor's wide, parallel outline is a key reason to choose this shape. It provides experienced riders with a stable platform for developing advanced maneuvers, making the board particularly relevant to bigger surfers who want to progress their riding.
The single-concave bottom and rocker help the board carry speed along the wave. For riders practicing tricks, maintaining that speed supports the approach to the next maneuver. Reflex Speedrail complements the shape with a refined rail profile designed to enhance speed, responsiveness, and release as the board transitions from edge to edge.
The quad fin setup adds traction and control while retaining a loose riding character. Its combination of drive and turning grip suits surfers who want to carve along the wave and develop technical surf-style maneuvers.
Flightlite V2 Pro Select is Phase 5's lightest surf-style build, with a stated 20% weight reduction. It emphasizes low weight and responsive board feel, complementing the Doctor's larger surf-style shape. 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 build. 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.
Compare rider weight and height with the suggested ranges below when selecting a Doctor. Length, width, and volume increase across the three sizes. Fin size also changes: the 55-inch board uses 4.3-inch fins, while the 57- and 59-inch boards use 4.7-inch fins.
| Length | Width | Volume | Fin Size | Suggested Weight Limit | Rider Height |
|---|---|---|---|---|---|
| 55" | 19" | 23.8 L | 4.3" | 225 lbs. | 5'6"–6'6" |
| 57" | 20.25" | 25.6 L | 4.7" | 250 lbs. | 5'7"–6'7" |
| 59" | 21.3" | 28.5 L | 4.7" | 275 lbs. | 5'8"–7'0" |
Recommendations assume average fitness and ability. Experienced riders may prefer smaller boards; beginners may need larger sizes.
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.
