North Sonar Foil Edition Aluminium 72cm – Modular Performance for Precision Foiling

The North Sonar Foil Edition Aluminium 72cm is a premium entry into modular foiling systems, designed for riders seeking durability, versatility, and precision across multiple disciplines such as hydrofoil surf wing, wing foiling, foil surfing, and wind foiling. Built with a refined aluminium mast and North’s advanced engineering systems, this foil edition delivers a balanced blend of strength, efficiency, and responsiveness.

Whether you’re progressing in wing foil sessions or exploring surf foiling in shallow waters, the Sonar AF72 mast setup provides a reliable and high-performing platform.

Refined Aluminium Mast for Strength and Efficiency

At the core of the Sonar Foil Edition is its 72cm aluminium mast, engineered with a refined profile that optimizes both weight and structural strength.

This updated mast design ensures:

• Excellent stiffness for precise control
• Reduced flex under load
• Lightweight handling for easier maneuverability

The aluminium construction offers an ideal balance between durability and performance, making it suitable for a wide range of conditions and rider levels.

Optimized for Shallow Water and Surf Foiling

The 72cm mast length is specifically designed for environments where control and clearance are essential.

Ideal conditions include:

• Shallow water riding
• Prone surf foiling
• Beginner to intermediate wing foil sessions

Compared to longer masts, the AF72 allows riders to maintain better control and confidence when learning or riding in tighter conditions.

This makes it particularly effective for:

• Hydrofoil surf wing progression
• Wave riding close to shore
• Low to moderate wind conditions

Modular Sonar Foil System Compatibility

One of the biggest advantages of this foil edition is its integration into the Sonar modular system, allowing riders to customize and upgrade components as their skills evolve.

Key modular benefits:

• Fully interchangeable parts (mast, fuselage, wings)
• Easy upgrades without replacing the full setup
• Adaptable for multiple disciplines

This flexibility ensures that your setup can evolve with your riding style, whether you focus on wing foiling, foil surfing, or wind foiling.

GeoLock System for Direct Power Transfer

North’s proprietary GeoLock Load Bearing Connection is a standout feature in the Sonar Foil Edition.

Advantages of GeoLock technology:

• Increased structural stiffness
• Seamless mast-to-fuselage connection
• Reduced movement and energy loss

This system locks components together so they feel like a single unit, providing a clean, direct ride feel with minimal drag in the water.

Improved Stability and Control with A700 Fuselage

The inclusion of the A700 fuselage enhances the foil’s overall balance and stability.

Performance benefits:

• Smoother ride in choppy conditions
• Better control during transitions
• Increased carving precision

The fuselage length is optimized to provide a playful yet stable feel, making it easier to carve and maintain control at varying speeds.

High-Efficiency Stabilizer for Balanced Performance

The Sonar Foil Edition Aluminium 72cm comes equipped with a carbon stabilizer (S270 or S01 depending on version) designed for efficiency and control.

Stabilizer highlights:

• Thin, high-aspect profile for reduced drag
• Improved pitch stability
• Easy recovery from surface breaches

This ensures a smooth and forgiving ride, even when pushing speed or performing maneuvers in dynamic conditions.

Built for Multi-Discipline Foiling

This foil setup is engineered to perform across various foiling styles, making it one of the most versatile options available.

Supported disciplines:

• Hydrofoil surf wing
• Wing foiling progression
• Foil surfing in waves
• Wind foiling and freeride
• SUP and tow foiling

Its adaptability makes it an excellent investment for riders who want one system for multiple uses.
