Modular Foil System

Customise your ride with our fully interchangeable foil components to explore multiple disciplines and riding styles all with one setup. Start building your quiver here. Seamlessly compatible with any North fuselage, stabilizer, mast or front wing.

Sonar AF72 or AF85 Mast

The new refined aluminium mast profile section gives the optimal balance between light weight design and exceptional strength for every discipline.

GeoLock Load Bearing Connection

Engineered for strength and stiffness, our unique GeoLock tapered geometry locking system provides a more effective load-bearing connection between the Mast and Fuselage, locking them together, so they feel like one piece.

New S270 Carbon Stabilizer

In perfect harmony with any Front Wing, our new higher aspect, thinner profile carbon pre-preg rear Stabilizer provides control and riding comfort, allowing fast pivoting turns and easy surface breach-recovery.

Sonar AF Foil Board Adaptor

Aluminium Board Adaptor for the AF55, AF72 and AF85 masts. FE-Analysis has allowed us to optimise the structure, increase strength in the areas of highest stress concentration and reduce unecessary weight in lower stress areas.

Industry-standard 165x90mm bolt pattern

The Sonar Foil System is designed to work in harmony with our unique DropBox fast-foil mounting system. The Dropbox has a longer track for a wider adjustment range, allowing you to precision-tune the foil set up for your rider weight.

NEW 700mm Fuselage

Cruise control. Our longer, CNC-machined anodised aeronautical-grade aluminium Fuselage offers a smoother, more stable ride across every foil discipline.

Supplied with Sonar Travel Bag

Stow your Sonar Quiver safely in between sessions with our Heavy Duty 600D Padded Travel Bag. Roomy enough inside to fit the complete Sonar Foil set, including multiple wings and masts inside their individual covers.
