2027 North Sonar Surf S125v3 Stabilizer

The North Sonar Surf S125v3 is a compact, high-performance rear stabilizer for advanced riders who want a loose, fast and highly responsive foil. It initiates turns instantly and adds real bite through the carve, while its foil sections keep the ride predictable across a wide speed range, so you get the extra maneuverability without giving up stability.

North recommends the S125v3 for surf foiling, wing foiling in waves and downwind, for advanced riders chasing maximum turn response. At 125cm², it is the most compact option in North's Surf stabilizer series.

Built for the Sonar Foil System

Like all Sonar stabilizers, the S125v3 mounts on top of the fuselage, keeping it clear of turbulence coming off the front wing for a cleaner ride. It's built from high modulus carbon pre-preg for a stiff, direct feel, and fits any Sonar fuselage with the included Stabilizer Screw Pack C.
