North Sonar Stabiliser

North Sonar Sonar Stabiliser. Flat, loose and fast. The Sonar Stabilisers are a high-performance upgrade to the Sonar Foil System for experienced riders.S185The 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.Moderate spanMedium high aspect ratio for efficient pumpingCompact outline for responsiveness in turnsStall speed to complement smaller SF Front WingsMinimal sweep outline improves low-speed performanceUpward curving tips provide directional stability and grip in turnsOption to remove wingtips and creating a flat / loose stabilizerPre-Preg CarbonTitanium ScrewsS205The S215 Surf stabilizer has a lower stall to complement the SF Front Wings.

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.Moderate spanMedium high aspect ratio for efficient pumpingCompact outline for responsiveness in turnsLower stall speed to complement SF Front WingsMinimal sweep outline improves low-speed performanceUpward curving tips provide directional stability and grip in turnsOption to remove wingtips and creating a flat loose 205cm stabilizerPre-Preg CarbonTitanium ScrewsS178Flat, 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.Top mounted for early breach recovery​Carbon pre-preg construction​Thin profile section for reduced drag​Pre-Preg CarbonS208Flat, loose and fast, the new S208 Stabilizer is another high performance upgrade to the Sonar Foil System for experienced riders.
