Sonar Surf Series Foil Set with Aluminium Mast

Performance & Feel

This set builds on the same aluminium AF platform. GeoLock fixes the mast to the fuselage with a tapered geometry locking connection, transferring load across the full cross-section of the mast profile for a direct, connected feel and a longer-lasting connection. Choose the AF72 for shallow water and prone surf foiling, or the AF85 for more ride height and a more forgiving ride in choppier conditions.

The SF front wing foil section is deliberately forgiving of changes in angle of attack, so you don't need expert technique or perfectly timed pumping to keep the glide going, and one pump gets you gliding again if you feel it about to stall. That forgiveness comes paired with a refined balance of roll stability and manoeuvrability, so you can still drive powerful rail-to-rail carves and lay down banking turns when you want to push it. 

Key Features

• Aluminium AF72 or AF85 mast: AF72 suited to shallow water and prone surf foiling, AF85 for more ride height and a more forgiving ride in rougher water
• A700 Fuselage: forgiving 700mm length, delays the pitching moment for more reaction time
• S270 Carbon Stabiliser: mounted on top of the fuselage for clean, undisturbed flow and an early breach warning
• SF Surf Series front wing: evolved foil section for super low stall speeds and effortless pumping
• Forgiving on angle of attack: one pump gets you back gliding if you're about to stall, without needing expert technique
• GeoLock connection: a tapered geometry locking system between mast and fuselage for a direct, connected feel
• Industry-standard US Twin Track mast pattern: works with North's DropBox mounting system for a wide adjustment range
