2024 North Sonar SF AF Foil Edition Bundle

The 2024 North Sonar SF AF Foil Edition Bundle pairs North's surf-oriented SF front wing series with the brand's aluminum foil platform, offering a complete hydrofoil setup built around low-speed stability and wave-riding performance. North designed the SF (Surf) wing line for prone surf foiling, downwind runs, and wing foiling in swell, while the AF (Aluminum Foil) mast and hardware keep the package accessible at a lower price point than North's carbon mast alternatives. The bundle ships as a full foil assembly — mast, fuselage, stabilizer, front wing, board adaptor, tool kit, and travel bag — so buyers can mount and ride without sourcing individual components.

North offers this bundle in ten configurations combining two mast lengths (AF72 or AF85) with five SF front wing sizes (SF680, SF830, SF930, SF1080, and SF1230), letting riders match lift and mast depth to their weight, local conditions, and discipline.

• Mast options: AF72 (720 mm, 2.23 kg) or AF85 (850 mm, 2.48 kg)
• Mast material: 6000-series anodized aluminum
• Fuselage: A700 — 700 mm length, CNC-machined anodized aeronautical-grade aluminum
• Stabilizer: S270 carbon pre-preg
• Front wing material: Pre-preg carbon with titanium screws
• Front wing sizes: SF680 (680 cm², 1.0 kg), SF830 (830 cm², 1.2 kg), SF930 (930 cm²), SF1080 (1080 cm², 1.5 kg), SF1230 (1230 cm²)
• SF aspect ratio range: 7.1 (SF1230) to 8.8 (SF930)
• Board mounting: Industry-standard 165 × 90 mm bolt pattern; compatible with North DropBox system
• Included: Mast, AF board adaptor, A700 fuselage, S270 stabilizer with cover, tool kit, screw packs, travel bag

This bundle targets intermediate to advanced foilers focused on surf-style riding — prone foiling, downwind paddling, and wing foiling in ocean swell. The SF wing series is shaped around low stall speeds and accessible pumping, which suits riders who want to catch and link bumps without needing a powerful sustained wind source. The longer A700 fuselage adds pitch stability that benefits riders still refining their pump timing or transitioning from flat-water foiling to open-ocean conditions.

Smaller wings in the lineup (SF680, SF830) suit lighter riders or those comfortable at higher speeds who want a tighter turning radius. Larger options (SF1080, SF1230) provide more lift at lower speeds, suiting heavier riders or lighter wind. The AF72 mast works well in shallow reef or shore breaks, while the AF85 gives more clearance and smoother tracking through chop.

Within North's Sonar foil ecosystem, this SF AF bundle sits as the surf-dedicated aluminum package. North also offers the Sonar MA v2 AF bundle, which pairs the same aluminum mast platform with the brand's higher-aspect MA v2 front wings geared toward freeride wing foiling and kite foiling rather than surf and downwind. For riders who want the SF surf wings on a stiffer, lighter platform, North sells carbon fiber CF72 and CF85 masts separately that accept the same fuselage and wing components through the shared GeoLock connection system.

Compared to competing aluminum surf foil packages — such as the Armstrong CF1600 package or the Axis BSC setup — the North SF AF bundle leans toward medium-to-high aspect ratios with relatively compact wing areas, prioritizing glide efficiency and carving response over raw low-end lift. The modular Sonar system also lets owners swap just the front wing or mast later without replacing the full assembly, which adds long-term flexibility as skills progress.
