North Sonar UHM Carbon Mast 95cm – Ultra-Stiff Performance Mast for Maximum Speed and Control

The North Sonar UHM Carbon Mast 95cm is engineered for riders who demand elite-level performance across hydrofoil surf wing, wing foiling, foil surfing, and wind foiling. Built with Ultra High Modulus (UHM) carbon technology, this mast delivers exceptional stiffness, reduced drag, and unmatched responsiveness—making it a premium upgrade for serious foilers.

Designed to push the limits of speed and efficiency, the 95cm version strikes the perfect balance between height, control, and high-speed stability, especially in choppy or open-water conditions.

Ultra High Modulus Carbon for Maximum Stiffness

At the core of the Sonar UHM mast is its advanced High Modulus Prepreg Carbon construction. This premium material significantly increases both bending and torsional stiffness compared to standard carbon masts, resulting in a more direct and connected riding experience.

Benefits of UHM carbon construction:

• Exceptional stiffness for precise control
• Immediate feedback underfoot
• Reduced flex at high speeds
• Improved energy transfer during pumping

This construction ensures that every movement translates directly into performance, making it ideal for advanced riders pushing their limits in wing foil and foil surfing.

15% Thinner Profile for Reduced Drag

One of the standout innovations of this mast is its ultra-thin hydrodynamic profile. North has reduced the thickness of the submerged section by more than 15%, significantly lowering drag while maintaining structural strength.

Advantages of the thinner profile:

• Faster acceleration
• Higher top-end speeds
• Smoother glide through water
• Increased efficiency in all conditions

This refined shape allows riders to maintain speed effortlessly, whether cruising, carving, or racing in wind foiling conditions.

Optimized Geometry for Speed and Control

The mast features a carefully engineered chord distribution along its length. The submerged section maintains an efficient shape to reduce drag, while the upper section increases in chord length to maximize stiffness without adding resistance.

Performance gains from optimized geometry:

• Better upwind drive
• Increased stability at speed
• Enhanced control in rough water
• Improved balance between rigidity and efficiency

This intelligent design ensures the mast performs consistently across multiple foiling disciplines.

Enhanced Glide and Pump Efficiency

The North Sonar UHM Carbon Mast 95cm excels in glide and pumping efficiency, two essential elements of modern foiling.

With reduced drag and increased stiffness, riders benefit from:

• Longer glide phases between waves
• More efficient pumping with less fatigue
• Smooth transitions during maneuvers

The result is a more fluid and energy-efficient ride, particularly beneficial for hydrofoil surf wing and downwind sessions.

Stability and Confidence in Open Water

At 95cm in length, this mast is designed for riders who frequently encounter choppy or open-water conditions. The extra height provides more clearance from the water surface, reducing the risk of breaching and improving overall control.

Why 95cm length matters:

• Better handling in waves and swell
• Increased clearance for aggressive turns
• More stability at high speeds
• Ideal for powered conditions

This makes it a preferred choice for advanced riders in wing foiling and wind foiling environments.

Reduced Ventilation for Consistent Performance

North has focused heavily on minimizing ventilation—an issue where air disrupts water flow along the mast. The refined trailing edge design significantly reduces ventilation, even in rough sea states.

Benefits of reduced ventilation:

• More consistent lift and control
• Increased confidence at speed
• Smoother ride in turbulent conditions

This ensures reliable performance across all water conditions.
