About the Longboard 9’1 Tri Fin US BOX

The shape of the 9’1 PRISM is very versatile. It allows for both noseriding in 30 cm and surfing in 1M50 and more. Its relatively flat rocker allows for excellent speed in soft waves. Its wide tail will give large sizes good buoyancy for more tight turn relaunch. Stable and well-balanced, you can advance on the nose whenever you like. Its 2+1 setup (2 FCS 1 GL side fins, 7.5 CMS + 1 central fin in US box size 9″, 23CMS) allows for a larger central fin for more pivot in the wave.

Who is the Longboard 9’1 US BOX suitable for?

Suitable for all sizes and practices, it is difficult to fault for both beginners and experts in challenging conditions. A reference.

The implementation of the stratification of our boards benefits from a rigorous specification to obtain more strength with less weight: • Climate-controlled stratification rooms to ensure ideal humidity levels, for perfect drying (more strength with the same stratification). • Vacuum stratification with resin overflow evacuation: fiberglass needs the right amount of resin necessary for its impregnation. Vacuum impregnation allows the resin to enter the fiber, the excess is evacuated through the drain. Because too much resin equals a heavier board, but above all less strong as fiberglass becomes brittle.

Construction Paulownia Eco Wood Concept

A new sandwich construction in epoxy and paulownia wood (very lightweight and resistant) that allows to stiffen the board and ensure better durability of the materials. The paulownia wood, also called “aluminum wood”, does not absorb water due to its low moisture content, it is very dense and allows for a watertight stratification under the epoxy coating. Our surfboards in paulownia are much stronger than traditional epoxy surfboards. Paulownia wood also has ecological properties, it grows at a much faster rate than wood usually worked in a factory (about 2 cm per day) and absorbs 10 times more CO2 than others.
