High-performance surf foil stabilizer engineered for the fastest, loosest surfing feel with increased maneuverability and speed.

The North Sonar S145v2 is designed to provide the ultimate surfing experience on a foil. Its anhedral rondure loosens up the front wing in the roll axis for a loose, surfable feel, while the optimized foil sections ensure predictability across a broad speed range. The moderate span creates an aspect ratio high enough for efficient pumping while remaining compact, with increased roll-ability for tighter and snappier turns. Recommended for prone or tow surfing with smaller front wings, by intermediate to advanced riders seeking increased maneuverability and speed.

Key Features:

• Anhedral Rondure Design - Loosens front wing in roll axis for surfable feel
• Optimized Foil Sections - Predictability across broad speed range
• Moderate Span - Compact yet efficient for pumping
• Increased Roll-Ability - Tighter, snappier turns
