Maximizing lightweight does not only mean making a light board but making a light board that LASTS. This is what we accomplished with the new UC construction. The EPS core is well known for lighter weight/strength ratio and memory compared to PU foam but it has one big limit, it absorbs water in case of a hole or a crack through the laminate.
Fortunately, we have put together the best of both worlds. In order to accomplish this feat, we have cut a 4 cm wide slice that runs throughout the entire outline of the board and have replaced the EPS external outline with 2 x PU outline slices that are glued to the EPS core. By adhering the PU to the EPS, we have created a 4 cms wide “waterproof” band that covers the entire rail, nose, and tail areas, keeping them totally waterproof in case of a crack through the laminate.
The EPS core covers 80% of the board and creates a lively and buoyant centre while the PU foam slices on the rails cover about 20% of the total foam volume. The PU rail slices combined with the deck and bottom carbon stringers laminated over the EPS core create a fantastic and unique pop and flex feel.

The Classic PU construction has been developed to create pure surfboards and to allow control over choppy waters. We have improved the weight and strength of the boards this year. We are now using a hi-volume lightweight pigment in the resin. This type of resin fills up the holes in the foam and reduces the amount of resin content in the glass fibres, making the boards lighter. The Classic boards have low fibre memory and low foam memory at the same time. This low memory gives the boards the right flex e feel. We recommend the Classic PU technology to the riders who love a comfortable and pure surfing feel under their feet.
