Product description:

Start building your modular foil set here. The new, improved aluminum AF mast is the perfect combination of lightness and exceptional strength, giving you confidence whether kiting, winging, surf foiling or riding behind a boat. Thanks to the fully interchangeable Sonar Foil System, you can easily adapt the configuration to different conditions and riding styles.

The mast was designed for durability and stiffness, offering an excellent strength-to-weight ratio. It uses the innovative GeoLock connection system, which delivers maximum feedback and minimal drag in the water.

• AF85 - the ideal choice for riding in more challenging, choppy conditions - increases stability and riding performance.

• AF72 - excellent for riding in shallow water and for prone surf foiling.

• Fuselage A700 - provides additional stability to the whole construction.

• S270 stabilizer made of carbon fiber - guarantees performance and precision in all conditions.

Sonar modular foil system

Customize your ride with fully interchangeable foil components to explore multiple disciplines and riding styles with a single set. Seamlessly compatible with any North fuselage, stabilizer, mast or front wing.

Sonar North AF72 or AF85 mast

The new, improved aluminum mast profile provides an optimal balance between lightweight construction and exceptional strength for every discipline.

GeoLock load-bearing connection

Designed for strength and stiffness, the unique GeoLock tapered-geometry locking system provides a more effective load-bearing connection between the mast and fuselage, locking them together so they act as one piece.

New S270 carbon stabilizer

In perfect harmony with any front wing, the new higher-aspect, thinner pre-preg carbon fiber rear stabilizer provides control and riding comfort.

Sonar AF foilboard adapter

An aluminum board adapter for the AF55, AF72 and AF85 masts. FE analysis allowed the construction to be optimized, increasing strength in areas of highest stress concentration and reducing unnecessary weight in areas of lower stress.

Industry-standard 165x90mm bolt pattern

The Sonar Foil System was designed to work in harmony with the unique DropBox quick-mount system. DropBox has a longer track, providing a wider adjustment range, allowing you to precisely fine-tune the foil to the rider's weight.

New 700mm fuselage

A longer, CNC-machined fuselage made of anodized aircraft-grade aluminum provides smoother and more stable riding in every foiling discipline.

North Sonar travel bag included

Store your Sonar North safely between sessions with the padded Heavy Duty 600D travel bag. Roomy enough inside to fit the entire Sonar Foil set, including multiple wings and masts in their individual sleeves.
