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. The SLX construction of this board makes it feel light, responsive and very sensitive under your feet.

• SLX
  • SLX EPOXY TECHNOLOGY
    SLX construction produces a controlled flex pattern by combining the versatility of epoxy materials with the added advantage of reduced weight. All SLX boards have an EPS core with a high-grade timber stringer, which is laminated by hand using epoxy resign, biaxial fiberglass and a specialized construction process.
    Featuring a high strength-to-weigh ratio, and designs CNC milled directly from the shapers files. SLX boards feel light, responsive and are very sensitive under your feet. These boards are extremely versatile, easy to ride, and can be used in wide variety of conditions.
