Sonar Surf Series Foil Set with Carbon Mast

Performance & Feel

This set combines North's top-tier CF carbon mast, fuselage and stabiliser with the SF Series front wing so the whole setup is tuned around low-speed glide from the outset. The pre-preg carbon construction throughout cuts swing weight, giving the set an agile, dynamic feel and strong pumpability, while GeoLock ties the mast to the fuselage with a tapered geometry locking connection for a direct, connected feel underfoot.

The SF front wing is the heart of the set's character. Its 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 is paired with a refined balance of roll stability and manoeuvrability, so you can still drive powerful rail-to-rail carves and banking turns when you want to push it. The stabiliser sits on top of the fuselage rather than below it, keeping flow clean and giving you an early breach warning before the front wing surfaces.

Choose between the CF72 mast, suited to shallow water and prone surf foiling, or the CF85, which performs across all disciplines with more ride height for choppy conditions.

Key Features

• CF72 or CF85 carbon mast: CF72 suited to shallow water and prone surf foiling, CF85 for more ride height and forgiveness in rougher water
• Pre-preg carbon fuselage and stabiliser: strong, durable and corrosion resistant, cutting weight without giving up strength or stiffness
• 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 165x90mm bolt pattern: works with North's DropBox mounting system for a wide adjustment range
• Sonar Travel Bag: room for your full carbon setup, with straps, clips and interior pockets
