What makes the Hydro Hull so progressive and popular, even still today, is the performance from the beveled rails and the single to double concave bottom. Full length edges lifted by the bevel on the rail create strong drive out of the turns and plenty of speed down the line, while the bevel makes it forgiving for even the most novice surfer. Lots of V with the double concave bottom makes rail to rail change fast and effortless, so the more advanced surfer can do a hard bottom turn.

Stable, fast, responsive, maneuverable, and fun in anything from ankle-high slop to overhead barrels, the Hydro Hull is the ideal all-around board for any surfer level or wave conditions.

• Polyester (PU)
  • TRADITIONAL POLYESTER OR PU TECHNOLOGY
    Polyester or PU construction uses traditional materials and laminating techniques to produce a strong, reliable surfboard with high quality finishes. All polyester boards are CNC milled from the shapers files and laminated by hand using quality components such as Hexcel fiberglass, Silmar resin and Bennett foam.
    For years traditional polyester boards have been at the forefront of performance surfing. These boards feature a progressive flex pattern controlled by a high-grade timber stringer and feel very reliable under your feet. Polyester construction will perform in all surf conditions and can be adapted to suit a wide variety of surfboard models.
