North Sonar Stabiliser

• Moderate span
• 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
• Pre-Preg Carbon
• Titanium Screws

S205

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.

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. 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.

• Clean undisturbed flow
• Flat / loose / fast
• Easy breach recovery
• Thinner profile
• Higher aspect ratio
• Less surface friction for better glide
• Pre-Preg Carbon

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 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.  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.
