Airush Protoy 2009

Rails - Square ABS rail for durability and a fast clean water release.
Rocker - 3 stage “competition” rocker for speed and early planning. The flip tip design prevents the nose from catching in choppy conditions.
Flex - Medium stiffness rating for a good blend of comfort and pop.
Bottom shape - The double concave bottom softens the ride in choppy conditions, increases the directional stability at speed and enhances edging and low wind performance.
Planform - The wide tips of the Protoy insure huge amounts of pop for the most progressive riding possible.
Fins - The new Metro Fin Series offer increased grip, with reduced drag through the refined foils shape and reduced chord.
Construction
Multizone Biotech HD
The Airush Multizone Biotech construction is a spin off from snowboard technology where a vertical wood core sandwich is combined with a stepped construction and an ABS rail. Due to the unique shape of the Protoy with extremely deep concaves the Protoy features a unique higher density Biotech construction to maintain stiffness and strength. In addition the tip areas comprise of a high density linear foam to accommodate the unique flip tips and reduce weight in the tip area.
