NORTH Sonar UHM Foil Mast 85004.270210
ULTRA HIGH MODULUS CARBON MAST
UHM73 / UHM80 / UHM85 / UHM95 / UHM105
The UHM80 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.
UHM85
The UHM85 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.
UHM95
Our new Sonar UHM95 Ultra High-Modulus Carbon mast exceeds the bending and torsional stiffness of the CF95 Carbon Masts, while reducing thickness and, hence, drag.
UHM105
The UHM105 has been optimised for racing. The thickness of the submerged part of the mast is a further 1mm thinner than the UHM80 and UHM85, to provide maximum top-end speed. As a result this mast is not for jumping. Like the UHM85, the chord length in the submerged region has been tailored to provide good upwind drive, while the chord length increases above the waterline to maximise stiffness.
PRODUCT DETAILS
Mast (with gasket), Cover (HM95), 1 x Sonar Fuselage Screw Pack B3 (2x M8x25mm Cap screws)*
*Sonar Aluminium Fuselage or older model Carbon Fuselage require 25mm Cap screws when paired with a UHM Mast.
Carbon Fuselage with tapered holes are supplied with M8x30mm Countersunk (CSK) screws, compatible with a UHM Mast.
**Mounting screws are included with North Foilboards and sold separately.
