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 re-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 the both worlds. In order to accomplish this feat, we have cut a 4 cms 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 center 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.
