Description
NORTH SONAR HM CARBON MAST
Incredibly thin. Impressively fast. We have reduced the thickness of the submerged portion of our new high modulus prepreg carbon spars by more than 15% compared to our standard carbon spars, while increasing bending and torsional rigidity.
The HM80 favors non-wind powered disciplines: prone surfing, pumping and downwind. Shorter rope length over the entire length of the mast reduces drag and increases maneuverability. This offers more glide, more efficient pumping and faster turns.
The HM85 covers all disciplines, focusing on foiling. Wind-powered disciplines require going against the wind to generate momentum. Part of this thrust comes from the forward wing and part from the mast. To provide this thrust efficiently, the length of the wing at the submerged part of the spar is slightly longer. Increase near the top of the mast to maximize stiffness without a drag penalty, as this part of the mast is out of the water once on the foil. A more efficient underwater body shape means less resistance and therefore a higher and easier to achieve top speed. Ventilation in the mast is now a thing of the past. We have paid special attention to this detail, so regardless of the sea state, the ventilation in the mast TE is significantly reduced.
The HM105 has been optimized for racing. The thickness of the submerged part of the mast is 1 mm thinner than that of the HM80 and HM85, to provide maximum top speed. As a result, this mast is not for jumping. Like the HM85, the chord length in the submerged region has been designed to provide good upwind handling, while the chord length increases above the waterline to maximize stiffness. A more efficient underwater body shape means less resistance and therefore a higher and easier to achieve top speed.
