North Sonar Carbon Foil Mast 85cm – Precision Engineering for Ultimate Foiling Control

The North Sonar Carbon Foil Mast 85cm is a premium component designed to deliver exceptional stiffness, control, and efficiency across all foiling disciplines. Whether you’re engaged in hydrofoil surf wing, wing foiling, foil surfing, or wind foiling, this mast is engineered to provide a direct connection between rider and foil, maximizing performance in every session.

Built with high-quality pre-preg carbon and featuring North’s innovative GeoLock system, the 85cm mast strikes the perfect balance between height, stability, and maneuverability—making it one of the most versatile mast sizes available today.

High-Quality Carbon Construction for Maximum Performance

At the heart of the North Sonar 85cm mast is its advanced pre-preg carbon construction. This manufacturing process ensures a consistent fiber-to-resin ratio, resulting in a mast that is both lightweight and incredibly stiff.

The increased stiffness translates into:

• More direct power transfer
• Immediate rider feedback
• Reduced flex under load

This gives riders a precise and responsive feel, essential for performance-oriented wing foil and foil surfing sessions.

Additionally, the carbon build ensures corrosion resistance, making it suitable for long-term use in saltwater environments.

Optimized Tapered Design for Efficiency

The mast features a carefully refined tapered geometry that enhances hydrodynamic efficiency. By reducing drag and optimizing load distribution, this design improves overall ride quality.

Benefits of the tapered design:

• Lower surface friction for smoother glide
• Improved speed and acceleration
• Efficient load transfer from board to foil

This optimized shape allows riders to maintain momentum effortlessly, particularly beneficial in wind foiling and wing foiling conditions.

GeoLock System for Seamless Connection

One of the standout innovations in the North Sonar system is the GeoLock tapered geometry connection. This system securely locks the mast and fuselage together, creating a unified structure that feels like a single piece.

Advantages of GeoLock:

• Enhanced load-bearing strength
• Improved energy transfer
• Reduced movement between components
• Increased durability over time

This seamless integration provides a more stable and predictable ride, especially when pushing performance limits.

Ideal Mast Length for All-Round Performance

At 85cm, this mast length is widely regarded as the “sweet spot” for most foiling disciplines. It offers enough height to handle choppy water while maintaining excellent control and maneuverability.

Why choose 85cm:

• Increased clearance over waves
• Reduced risk of breaching
• Better control in choppy conditions
• Versatility across disciplines

The added length compared to shorter masts improves ride stability and overall performance, particularly in rough water environments.

This makes it ideal for:

• Hydrofoil surf wing riding
• Wing foiling progression
• Foil surfing in waves
• Wind foiling in stronger conditions

One-Piece Design for Strength and Durability

The North Sonar Carbon Mast features a refined one-piece construction that enhances both strength and longevity.

Key structural benefits:

• Increased rigidity
• Reduced weak points
• Improved durability under high loads

This design ensures consistent performance across all conditions, from flat water cruising to aggressive carving sessions.

Universal Compatibility and Easy Setup

The mast is designed with a standard 165x90mm mounting pattern, making it compatible with a wide range of foil boards.

Compatibility features:

• Works with North Sonar Carbon and Alloy fuselages
• Fits most industry-standard foil boards
• Modular system for easy upgrades

This flexibility allows riders to customize their setup according to their skill level and riding style.

Enhanced Performance in Choppy Conditions

The 85cm length provides improved ride height, which is particularly beneficial in choppy or wave-filled conditions.

Performance advantages:

• Smoother ride over rough water
• Better wave clearance
• Increased confidence at speed

This makes the mast a reliable choice for riders pushing their limits in dynamic environments.
