Construction and Materials

Monocoque Construction – Integrating the top glass and the bottom glass into one. Generating a more durable board on side impacts to prevent delamination.

Layered Glass – Hyperlite's fiberglass is available in 3 weights depending on the board. Over time, traditional woven glass fibers will separate. With layered glass every Hyperlite deck will have the same pop off the double up year after year.

Biolite 3 Core – The secret recipe Hyperlite has been perfecting since day one. This core material is the gold standard in the industry and used throughout their line. Bio 3 is their lightest and most durable formula to date.


Wide Tail Profile – The wider the tail shape the more push you have down the wave with increased ollie power.

Squash Tail Shape – A squarer back with rounded corners delivering a snappy feel with increased hold in the wave.

Butch Custom – Scott Bouchard has been shaping wakeboards for close to twenty years, working with the biggest legends in the sport. Based in Satellite Beach, Florida Scott’s influence on wakeboard and wakesurf shapes can be seen throughout Hyperlite line up.


2.6" Tip / 0.8" Tail


Dual Concave Base – Channeling water into two streams through the fins and out the tail allowing for a fast and loose feel.


Rolled Edge Profile – A more rounded rail shape that suites beginners and intermediate surfers, great for your first surf session.


Two 1.5" Fish Fins

One 2.4" Fish Fin

Additional Features

Molded EVA Traction – Ultra grade EVA foam that is molded has a smoother finish and I considered more comfortable.

Do Not Store in Boat Board Racks – evo does not recommend storing your wakesurfer in boat board racks. Many wakesurf boards are fragile and can be easily damaged by these racks, which is not covered under manufacturer warranty.
