Modular

The modularity of the Sonar range is the plug and play functionality we've always dreamed of as kiters. Effortless and intuitive. You'll notice how easy the ride and how quickly you feel at one.

Cross disciplines with ease, whether you are kite foiling, wake foiling, foil surfing or SUP foiling.

Focused on performance, durability and rider comfort, our Sonar Modular Foil technology represents North’s design philosophy at its most pure: stripped right back to only the necessary. With a range of fully interchangeable components, the Sonar system allows you to embrace the conditions by customising your setup.

Choose either the Freeride Edition or the Surf Edition to start your Sonar journey. To improve performance or change to a different riding style, simply select a different mast height and/or wing size.

Engineered to last, our 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.

Screws engage the GeoLock while the load transfer now takes place over the full cross-section of the mast profile, allowing for more efficient load distribution and a longer-lasting connection.

The Stabilizer’s positioning on top of the Fuselage allows for a clean, undisturbed approaching flow and easy breach recovery.

Surface piercing of the Stabilizer is not a problem, as the Front Wing sits deeper in the water and is still fully submerged, giving you that extra time to react and adjust your ride height.

Cross disciplines with ease. Experience endless glide.

We’ve combined strong, lightweight, long-lasting materials, with a more efficient way to assemble the foil system.

Our hydrofoil design is highly data driven. But even the best-looking numbers don’t necessarily mean a foil will manoeuvre and perform that way in real life. In the end, it comes down to having the expertise and knowledge required to arrange all the parts in the system for a seamless foiling experience. Teaming up with George Hradil from Delta Surf Foils has helped us refine the Sonar Foil performance. George has been designing and building high-performance racing foils since 2013, and since 2017 has applied his years of materials research and design philosophy into constructing some of the most advanced surf hydrofoils on the market.

Sonar Freeride Edition

Sonar Freeride Edition

850 WING + 85CM MAST

A forgiving and well-balanced ride, with amazing performance at the top and bottom end speeds. The Sonar Freeride Edition holds lift through gybes and tacks without stalling, allows easy breach recovery and lets you step up your foil game with ease.

Anhedral Wing profile and swept back outline allows for a more agile flight mode and roll stability during manoeuvres. Optimized low drag foil section allows for thrilling top end speeds combined with unseen low stall speed.

The 85cm Mast allows you to heel over more, fly the kite lower and further power up the foil system for a more controlled high-speed ride.

The Sonar Foil System can be mounted to any foil board with a 165x90mm bolt pattern.

Sonar Surf Edition

Sonar Surf Edition

1650 WING + 70CM MAST

The ultimate in soaring comfort and performance, the Sonar 1650 Wing delivers a stable platform with very low drag to lift ratio and is paired with the 70cm Mast for endless carving.

Pump with ease to connect multiple waves. Unbelievably low stall speed.

A real crossover from Kite Foil to Foil Surf, SUP Foil, Wake Foil and Tow Foil Surf for all rider weights. Make use of the fully interchangeable Sonar Foil System to extend your playtime on the water by adding an 1150 or 850 Front Wing and an 85cm Mast.

The Sonar Foil System can be mounted to any foil board with a 165x90mm bolt pattern.

SONAR 850 WING

SONAR 850 WING

PERFORMANCE FREERIDE. Amazing top end and bottom end speed, yet playful and forgiving, the lightweight carbon Sonar 850 is your ultimate Freeride Wing. Smooth control through the entire speed range and an exceptionally low stalling speed allow you to master new manoeuvres faster.

SURF | WAKE | SUP. The ultimate in soaring comfort and performance, the lightweight carbon sandwich Sonar 1650 creates a stable, forgiving platform for effortless transitioning between toe-side and heel-side. Extremely low profile for an incredibly efficient lift to drag ratio and unbelievably low stall speed.

SONAR 40 MAST

SONAR 40 MAST

Our 40cm School mast, for those first-time feels, is an ultra-forgiving mast suitable for “skimming” just above the water and easy recovery.

SONAR 70 MAST

SONAR 70 MAST

The ideal mast height for a surf-style hydrofoil, perfect for prone foil-surfing in waves and for Freeride kite foiling in shallow waters.

SONAR 85 MAST

SONAR 85 MAST

The 85cm Mast is ideal for freeride foiling and increases overall ride performance in choppy conditions. This Mast length allows you to heel over more, fly the kite lower and further power up the foil system for a more controlled high-speed ride.

SONAR MAST TO BOARD ADAPTOR

SONAR MAST TO BOARD ADAPTOR

The Sonar Foil System is connected to the board by a lightweight CNC-machined aluminium Board Adaptor with a tapered geometry locking connection that engages with the mast. Fusing Board Adaptor and mast together to build one union for optimum load transfer and a stronger, more direct feeling and steering impulse when foiling
