North Sonar UHM Carbon Mast 2025

Sonar UHM Carbon Mast

Le North Sonar HM Carbon Mast est un mât de foil en carbone haute performance de la marque North Kiteboarding.
Voici quelques caractéristiques clés : Matériaux : Conçu en carbone haute module, ce mât est plus léger et plus rigide que les modèles précédents. Rigidité accrue : Offre une sensation et une réponse plus directes grâce à une rigidité supérieure en flexion et en torsion. Épaisseur réduite : L'épaisseur du mât a été réduite de plus de 15 %, ce qui diminue la traînée et améliore la maniabilité. Modèles disponibles : Disponible en différentes longueurs (80 cm, 85 cm, 95cm, 105 cm) pour s'adapter à divers styles de pratique.

UHM95-HM105 Not for jumping


Superior stiffness = a more direct feel and response.
But High-Modulus Carbon alone is nothing without good design.
Our new High-Modulus Carbon masts exceed the bending and torsional stiffness of our Carbon Masts while reducing thickness by over 15% and, hence, drag. The section shapes have been tailored specifically for these masts to provide low drag. The laminates have been individually designed for each mast length to give optimum performance.

HM80 MAST – SURF / DW / PUMP
Prone Surf, Pump, Downwind
The HM80 favours disciplines without wind power.
The shorter chord length over the whole length of the mast provides reduced drag and increased manoeuvrability.
This means more glide, more efficient pumping, and quicker turns.

HM85 Mast - WING
All-purpose foiling 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 HM85 mast is slightly longer than that of the HM80. The chord length 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.
The result is a super-stiff mast for a more direct feel and response, ideal for riders of any ability

HM105 Mast - RACE
Kite and Wing Foil Racing
Heel over and drive upwind.
The HM105 has been optimised for racing. The thickness of the submerged part of the mast is a further 1mm thinner than the HM80 and HM85 to provide maximum top-end speed. As a result, this mast is not designed for jumping, it is designed to go fast with the focus to reduce drag.
Like the HM85, 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.

High-Modulus Carbon
Superior Stiffness = Superior Performance
What does HM mean?
Modulus of Elasticity (E) is a measurement of the stiffness of a material and is defined as the ratio of stress to strain when the material is deformed. The higher the modulus, the stiffer the material (i.e., the greater the stress necessary to cause deformation).
How does it compare to other carbons? High Modulus carbon fibers are created through specialized heat treatment processes which deliver much higher tensile modulus values around 57 msi (million pounds per square inch), but at a reduced tensile strength of 640 ksi. This fiber will produce a part that is much stiffer but will lower tensile strength.
Standard Modulus carbon fibers are recognised as the most common and cost-effective fibers. These fibers exhibit a fiber modulus of 33-36 msi and can have tensile strength of 500-700 ksi
