2021 North Sonar Complete Kite Foil

The 2021 North Sonar Complete Kite Foil is a modular aluminum hydrofoil package from North Kiteboarding, bundled with the brand's Sonar 1500R reflexed front wing. Designed by hydrofoil engineer George Hadril, the Sonar system was built around interchangeable components that work across kite foiling, wing foiling, and prone surf foiling. This particular bundle pairs the 1500R carbon pre-preg front wing with North's CNC-machined aluminum mast and hardware, offering a complete setup at a lower price point than the brand's full-carbon configurations.

The package ships with everything needed to mount to a compatible foil board: mast, fuselage, front wing, stabilizer, board adaptor, hardware, tool set, and a travel bag. Buyers choose between two mast lengths — 70 cm (AK70) or 85 cm (AK85) — depending on riding conditions and preference.

• Front wing: Sonar 1500R (1500 cm², carbon pre-preg, 1640 g)
• Stabilizer: S01 (carbon pre-preg)
• Fuselage: A600 (CNC-machined 6061-T6 aluminum)
• Mast lengths: 70 cm (AK70) or 85 cm (AK85)
• Mast material: CNC-machined 6061-T6 anodized aluminum
• Board mounting pattern: 165 × 90 mm
• Mast-to-fuselage connection: GeoLock tapered geometry locking system
• Included accessories: AK Board Adaptor, Foil Tool Set, Screw Packs A/B/C, wing cover, stabilizer cover, travel bag

This foil targets beginner-to-intermediate kite foilers who want a complete, ready-to-ride package without assembling individual components from across the Sonar range. The 1500R front wing has a large surface area that produces lift at lower speeds, making it forgiving during early learning phases while still carrying enough speed range — roughly 8 to 25+ mph according to North's design notes — to remain engaging as skills progress.

The AK70 mast suits shallow-water spots and riders still building confidence at lower ride heights. The AK85 adds clearance for choppier conditions and more aggressive turning. Both mast lengths use aluminum rather than carbon, which keeps the price accessible and provides durability that tolerates the inevitable impacts that come with learning. Riders who already foil confidently and prioritize weight savings may prefer North's carbon mast options instead.

Within North's 2021 Sonar range, this bundle sits as the aluminum kite-specific package. North also offered a Kite Edition with the smaller 1150 front wing for riders wanting a more compact, speed-oriented setup, and separate mast-and-fuselage kits without a front wing for those building a custom configuration. The Sonar system's modularity means the 1500R wing included here can later be swapped for North's 850, 1150, 1850R, or high-aspect HA-series wings as riding priorities change.

As a 2021 model, this package predates North's later Sonar MA series, which introduced updated mast profiles and refined wing shapes. Comparable aluminum kite foil packages from the same era include the Slingshot Hoverglide and the Cabrinha Hi:Rise, both of which targeted a similar entry-to-intermediate price bracket with alloy construction and modular wing compatibility.
