Designer Notes | Sonar Stabilizers

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,” explains Uli Sommerlatt, North Foils Product Manager.
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,” says Mike Raper, North Brand Director. “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.”

Can I combine these with my Moses front wings? Kitefoiling

My stabilizer says S01. Where does this fit in?

[@NorthFoils]

Hi there, The S01 stabiliser is an older model. The S01 has a an aspect ratio of 4.7 - our lowest aspect ratio, giving you a very stable ride at slow speeds. Hope this helps, Frankie from North 🤙

Got it! New to this sport, first summer with a wing and foil 😇. So, I'm running the 700 fuse with a 1500R and sure it feels stable but would like it to lift a bit earlier, could a new stab help with this? Regards Magnus@@NorthFoils

@@magnusnr83 Hi there, I hope you enjoy wing foiling; we are all stoked about it. I suggest changing the mast position first before changing your setup. Moving the mast forward will effectively decrease your front foot pressure, and the foil will pop up faster. I hope this helps, Frankie from North🤙
