NORTH - SONAR HM CARBON FOIL MAST

It doesn't get any finer than that. Extremely fast.

We have reduced the thickness of the submerged part of our new high modulus pre-preg carbon masts by more than 15% compared to our standard carbon masts, while increasing bending and torsional stiffness.

The HM80 focuses on windless disciplines - prone surf, pump and downwind. The shorter chord along the entire length of the mast reduces drag and increases maneuverability. This allows for better glide, more efficient pumping and faster turns. The HM85 covers all disciplines, with an emphasis on wing-foiling. Wind-powered disciplines require sailing against the wind to create forward thrust. Part of this thrust comes from the front wing, the other from the mast. To provide this propulsion effectively, the chord length in the submerged part of the mast is slightly longer. It increases near the top of the mast to maximize stiffness without penalizing drag, as this part of the mast is out of the water once on the foil.

A more efficient underwater body shape means less drag and therefore a higher and easier to achieve top speed. Ventilation on the mast is now a thing of the past. We have paid special attention to this detail, so that regardless of the sea state, ventilation on the mast TE is significantly reduced. The HM105 has been optimized for racing.

The thickness of the submerged part of the mast is still 1 mm thinner than the HM80 and HM85, in order to obtain maximum speed. Therefore, this mast is not made for jumping. As with the HM85, the length of the chord in the submerged area has been adapted to ensure good upwind, while the length of the chord increases above the waterline to maximize stiffness. A more efficient body shape underwater means less drag and, therefore, a higher and easier top speed to achieve...
