North Sonar High Aspect V2 Front Wing
Low drag, high speed, and exceptional glide across nine precisely spaced sizes—from the race-focused HA550 to the light-wind and pumping-oriented HA1450.
The North Sonar High Aspect V2 Front Wing is designed for riders who prioritize efficiency, acceleration, glide, and top-end performance. Its wide-span, short-chord outline and thin foil profile reduce drag while providing the lateral stability needed to carry speed with confidence. Refined wingtips support clean recovery when a tip breaches, while the carbon pre-preg construction creates a stiff, direct, and consistent feel underfoot.

Why You’ll Love the North Sonar HA V2
Speed Without Excess Drag
The short chord and thin foil section are engineered to reduce resistance through the water, allowing the HA V2 to accelerate quickly and maintain speed with less rider input.
Efficient, Long-Range Glide
Once moving, the high-aspect outline carries energy efficiently. This helps riders link swell, pump between waves, cover distance, and maintain momentum through transitions.
Stable High-Aspect Feel
The extended wingspan adds lateral stability and tracking. Compared with a lower-aspect wing of similar area, expect more glide and a slightly longer natural turning radius.
Confident Tip-Breach Recovery
Refined wingtip sections help resist ventilation when a tip leaves the water, supporting faster carving and cleaner recovery without an abrupt loss of lift.
High-Aspect Performance Across Nine Sizes
HA550–HA750: Maximum Speed
The three smallest sizes have less planing area and higher stall speeds. They are designed for advanced high-speed wing foiling, racing, kite foiling, and powered conditions.
HA850–HA1050: Performance Core
These sizes balance speed, glide, and maneuverability for intermediate-to-advanced wing foiling, prone foiling, tow foiling, and kite foiling.
HA1150–HA1250: Glide and Connection
More area provides additional lift for wing foiling, smaller surf, downwind swell, coastal runners, pumping, and connecting multiple waves.
HA1450: Maximum Lift in the Range
The HA1450 is the best match for lighter wind, heavier riders, dock starts, extended pumping, wake riding, and efficient coastal runs.
Key Features
Carbon Pre-Preg Construction
A carefully controlled carbon pre-preg layup provides high stiffness and direct feedback while helping minimize unwanted flex and low-frequency vibration.
Thin High-Speed Profile
The relatively short chord creates a thinner foil profile, reducing drag and improving speed, acceleration, and high-end efficiency.
High-Aspect Outline
Aspect ratios between 10.0 and 10.6 give the range its distinctive combination of efficient glide, stability, and speed retention.
Refined Wingtip Sections
Purpose-shaped tips help the foil recover cleanly from tip breaches and support tighter, faster turns with less risk of ventilation.
Consistent Family Feel
The nine sizes are tuned as one family, providing predictable balance and a familiar stance as riders change front-wing size for different conditions.
Sonar Modular Compatibility
Each wing is designed for the North Sonar modular foil platform, allowing riders to build a complete setup with the appropriate Sonar fuselage, mast, and stabilizer.
Performance Feel
Fast and Direct
The stiff carbon construction and thin profile create immediate response, efficient acceleration, and a connected feel between rider input and foil movement.
Glide That Rewards Speed
The HA V2 becomes more efficient as speed builds. It rewards riders who maintain momentum through gybes, pumping sequences, and transitions between swell.
Stable but Not Beginner-Oriented
The span provides lateral stability, but the thin profile and higher stall speed require more active speed management than North’s lower-aspect freeride wings.
Size-Dependent Turning
Smaller wings feel faster and more responsive, while larger sizes favor lift, glide, pumping efficiency, and connection through softer conditions.

Tail guidance: North’s performance recommendation places the HA950 and smaller on the S178 and the HA1050 and larger on the S208. Rider weight and desired pitch support matter: a heavier rider or anyone wanting more front-foot pressure and stability may prefer the larger S208 on a smaller HA wing.
Recommended Sonar Stabilizer
HA550–HA950: Sonar S178
The S178 is the performance-oriented match for the smaller HA wings. Its reduced area lowers drag and creates a looser, faster, and more maneuverable feel for experienced riders.
HA1050–HA1450: Sonar S208
The S208 provides the recommended balance of speed, pitch support, and front-foot pressure for the larger HA wings. Its efficient profile is specifically designed to complement the HA range.
Important: The stabilizer is sold separately. Tail choice can change with rider weight, discipline, fuselage length, and personal preference. Contact Windance if you want help choosing between the S178 and S208.

North Sonar HA V2 FAQ
What does HA mean?
HA means high aspect. The wing has a relatively wide span and short chord for its area, creating efficient glide, reduced drag, and high-speed stability.
Is the HA V2 suitable for beginners?
It is primarily intended for intermediate-to-advanced riders. Its higher stall speed requires better speed management than a lower-aspect freeride or progression wing.
Which sizes are best for wing foiling?
The HA850–HA1250 are the core wing-foiling sizes. Smaller wings favor stronger wind and higher speed, while the HA1150–HA1450 add lift for lighter wind and heavier riders.
Which stabilizer should I use?
Use the S178 as the performance recommendation for HA550–HA950 and the S208 for HA1050–HA1450. Heavier riders may prefer the additional pitch support of the S208 on a smaller wing.
Does the selected size include mounting screws?
Yes. HA550–HA750 include M8 × 23 mm screws, HA850–HA1150 include M8 × 25 mm screws, and HA1250–HA1450 include M8 × 30 mm screws.
Is this a complete foil?
No. The listing includes the selected front wing, its cover, and the appropriate front-wing screw pack. A compatible Sonar mast, fuselage, stabilizer, and board connection are sold separately.
Why Choose the North Sonar HA V2?
The North Sonar High Aspect V2 range gives experienced riders a precise way to tune speed, lift, glide, and maneuverability without leaving the Sonar modular platform. From the race-oriented HA550 to the lift-rich HA1450, every size shares the same low-drag philosophy, stiff carbon pre-preg construction, refined wingtip behavior, and efficient high-aspect feel.
