Description With 135mm from the leading edge to the trailing edge, the NSP Airwave Mast is one of the most efficient mast shapes on the market right now. Durable, ultra-stiff, and affordable, these are great for shallow-water wakeboarding from a winch or off-shore downwinding with some serious chop. Cover included Note that all NSP masts that are sold separately are supplied with premium 600-D nylon covers to protect your investment. 80cm Mast Intermediate to more advanced riders will appreciate the additional length of the 80cm mast. Weighs 1.9kg. Suitable for surf, SUP, winging, wake, pumping, and downwinders. With a width of 135mm (5.31”), these masts are 22.5% wider than most others on the market. The wider cord allows for a more efficient foil profile, more directional stability, and higher rigidity of 6061-T6 aircraft-grade aluminum. All Airwave masts feature three full-length reinforced channels for increased stiffness. Airwave masts are anodized for protection and a great look, and sealed with silicone plugs to keep them watertight.
