North Sonar Stabilizer Rear Wing

Sonar S142 - Glide Series (New)

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.

Sonar S192 - Glide Series (New)

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 new S192 has effortless glide and is fast and agile. When paired with bigger downwind front wings, an intermediate rider will find it super stable and easy to pump. The S192 also pumps efficiently with the SF and the new Pump Front Wings. It is ideal for charging in the surf, pumping, and connecting multiple waves with ease

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

Materials
High Modulus Carbon Prepreg
Titanium Screws

Sonar S185 - Surf Stabilizer (New)
The smaller S185 Surf Stabilizer is designed to pair with the smaller SF Series Surf 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.

Features:
Medium high aspect ratio for efficient pumping
Compact outline for responsiveness in turns
Stall speed to complement smaller SF Front Wings
Minimal sweep outline improves low-speed performance
Upward curving tips provide directional stability and grip in turns
Option to remove wingtips and creating a flat / loose stabilizer

Sonar S238 - High Speed Stabilizer (New)
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 manoeuvrability. The S238 is designed to match the new MA1200/MA1500 and larger HA front wings, giving your setup a faster and more responsive feel. 

Features:
Flat / loose / fast
Thinner profile
Higher aspect ratio

Sonar S215 - Surf Stabilizer
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.

Features:
Moderate span
Medium high aspect ratio for efficient pumping
Compact outline for responsiveness in turns
Lower stall speed to complement SF Front Wings
Minimal sweep outline improves low-speed performance
Upward curving tips provide directional stability and grip in turns
Option to remove wingtips and creating a flat loose 205cm stabilizer

Sonar S178 - High Speed Stabilizer
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 manoeuvrability.  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.  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 manoeuvrable. Experienced riders will really feel the difference. A new tail can have a big impact on your style.

Sonar S208 - High Speed Stabilizer
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 manoeuvrability.

As we’ve increased our front wing range, we’ve needed to match the lift force of the front wing with the stabilizer.
