North Sonar Stabilizers

S215 Surf

The S215 Surf stabilizer has a lower stall to complement the SF Front Wings. Its moderate span creates an aspect ratio high enough for efficient pumping, while remaining compact for responsiveness in turns. The minimal sweep outline improves low-speed performance and effectively reduces fuselage length compared to swept stabilizers. Tips curve upwards to provide directional stability, inspiring confidence during takeoffs and grip in turns. Advanced riders seeking a looser feel may choose to remove the wingtips, using the dashed guideline graphic, to create a completely flat stabilizer with a 205cm2 area.

S145v2

The S145v2 is designed to provide the fastest, loosest surfing feel. Its anhedral rondure loosens up the front wing in the roll axis, while the foil sections ensure predictability and a broad speed range. Its moderate span creates an aspect ratio high enough for efficient pumping while remaining compact, with increased roll-ability for tighter and snappier turns. Recommended for use prone or tow surfing with smaller Front Wings, by intermediate to advanced riders seeking increased maneuverability and speed.

Increased looseness and speed
Moderate span with medium-high aspect ratio (8.4) for efficient pumping
Compact outline for responsiveness in turns
Stall speed complements smaller Front Wings
Ventilation-free tip breaching

S320, S270, S210

Exceptional glide. Our new thinner profile and higher aspect ratio carbon stabilizers offer reduced resistance and a more efficient outline. The S270 is your go-to for all round kite, wing and surf performance, offering optimal balance, speed, efficiency and control. Pair the S210 with a smaller front wing for high-speed performance and a more agile feel. Pair the S320 with a larger front wing for early planing, greater balance and stability.

Clean undisturbed flow
Easy breach recovery
Thinner profile
Higher aspect ratio
More efficient outline shape
Less surface friction for better glide

S238

Flat, loose and fast. The S238 Stabilizer is a high-performance upgrade to the Sonar Foil System for experienced riders. It has a higher aspect ratio than the S270, which means less drag, and the flatter rondure (front view) enables more maneuverability. The S238 is designed to match the new MA1200/MA1500 and larger HA front wings, giving your setup a faster and more responsive feel. The North stabs are mounted on top of the fuselage, which helps them to avoid turbulence from the flow of the front wing, creating a smoother ride. This top mounting also gives the rider an early breach warning - the stab pierces the water surface first, giving you a better chance of recovery before your front wing gets too high. Like the Front Wings, all Sonar Stabilizers are pre-preg carbon construction, ensuring optimal stiffness and direct performance. The thin profile section reduces drag, while the material properties help maintain structural integrity and rigidity. Stabs have a huge influence on performance. As you progress to smaller wing sizes, we recommend changing to a smaller stabilizer to be more maneuverable. Experienced riders will really feel the difference. A new tail can have a big impact on your style.

S208

Flat, loose and fast, the new S208 Stabilizer is another high performance upgrade to the Sonar Foil System for experienced riders. The S208 has a higher aspect ratio than the S210, which means less drag, and the flatter rondure (front view) enables more maneuverability. As we’ve increased our front wing range, we’ve needed to match the lift force of the front wing with the stabilizer. While your front wing creates vertical lift, your stabilizer has a downward acting force, which prevents the front wing from nose-diving. A larger stabilizer translates into more front foot pressure, while a smaller stabilizer equals less front foot pressure. The North stabs are mounted on top of the fuselage, which helps them to avoid turbulence from the flow of the front wing, creating a smoother ride. This top mounting also gives the rider an early breach warning - the stab pierces the water surface first, giving you a better chance of recovery before your front wing gets too high.

S178

Flat, loose and even faster, the new S178 Stabilizer is a high speed upgrade to the Sonar Foil System for experienced riders. We recommend pairing the S178 with Front Wing size HA950, or smaller. The S178 has a higher aspect ratio than the S208, which means less drag, and the flatter rondure (front view) enables more maneuverability. As we’ve increased our front wing range, we’ve needed to match the lift force of the front wing with the stabilizer.

S142

With their high aspect ratio and thin sections, the Glide Series Stabs allow you to cover insane distances with minimal work (downwind, pump or prone). Stabilizers need to be stiff to provide precise and predictable turning and pumping, so we’ve engineered the Glide Series with HM carbon. This allows us to achieve the high stiffness we require despite the thin, high-aspect shape. The S142 has higher performance and is crazy fast and whippy. Your average rider may find it a little more advanced for pumping, but if you put in the energy, it will maintain glide. The S142 has enough holding power to take you right up to the DW1400, but we recommend the S192 for larger sizes.

High aspect ratio maximizes glide
Matches lift profile of higher-aspect front wings
Broad speed range
Low-speed takeoffs
Reliable pumping

S122 Glide

We’ve designed the S122 Glide Stabilizer for lighter and intermediate to advanced riders to use in big, clean conditions where speed and glide are a priority. Its small size and high aspect ratio (11.2) unlock maximum speed and glide from the front wing, allowing you to cover insane distances with minimal work. The anhedral rondure loosens up the roll axis, increasing the maneuverability of wider-span front wings.

Recommended for use with our smaller DW690, DW750, and DW820, the S122 could also be used for prone foiling by advanced riders seeking speed and glide combined with a loose feel. Engineered in High Modulus Carbon to ensure stiffness for precise and predictable turning and pumping.
