The North Sonar S145v2 is the most performance-oriented stabilizer in the Surf Series, designed for riders seeking maximum speed, maneuverability and a true surf-style feel. Its anhedral rondure loosens the foil in the roll axis, delivering tighter turns, faster rail-to-rail transitions and a highly responsive ride.

With an Aspect Ratio of 8.4, the S145v2 balances efficient pumping with an extremely compact and agile outline. The result is a stabilizer that feels fast, playful and predictable across a wide speed range.

Designed to pair with smaller and faster Sonar front wings, the S145v2 excels in prone surf foiling, tow foiling and advanced wing foil setups focused on speed and carving performance.
