North SONAR HM Carbon Mast

Impossibly thin. Impressively fast. We’ve reduced the thickness of the submerged portion of our new High Modulus Prepreg Carbon masts by over 15% compared to our standard Carbon masts, while also increasing both bending and torsional stiffness. The HM80 favours disciplines without wind power - prone surf, pump and downwind. The shorter chord length over the entire mast length reduces drag and increases manoeuvrability. This delivers more glide, more efficient pumping, and quicker turns. The HM85 covers all disciplines, with a focus on wing-foiling. Wind-powered disciplines require edging against the wind to create forward drive. Some of this drive comes from the front wing, and some comes from the mast. To efficiently provide this drive, the chord length in the submerged part of the mast is slightly longer. It increases near the top of the mast to maximise stiffness with no drag penalty, as this part of the mast is clear of the water once on foil.
