North Sonar AF Foil Set

The North Sonar AF Foil Set is where most riders start building their North foil quiver. An aluminium mast platform ready for any Sonar front wing you choose to add to it.

  • Complete modular foil platform: aluminium mast, board/baseplate adapter, fuselage, stabiliser and travel bag in one set
  • For kite foiling, wing foiling, surf foiling and tow foiling
  • Built for intermediate+ riders building their foil quiver
  • GeoLock connection for a clean, direct feel with minimum resistance
  • Refined aluminium mast profile, balancing light weight and strength
  • The mast is compatible with any North Sonar fuselage, stabiliser or front wing

Performance & Feel

The Sonar AF Foil Set is the starting point North for building a modular foil quiver, and it's built to grow with you. The refined aluminium mast profile balances light weight against genuine strength, so you're not choosing between durability and performance as you move between disciplines. GeoLock fixes the mast to the fuselage with a tapered geometry locking connection, so load transfers across the full cross-section of the mast profile rather than concentrating at a single point. The result is a direct, connected feel with minimum resistance through the water, and a connection built to last.

Two mast lengths cover different conditions. The AF72 suits shallower spots and prone surf foiling, where a shorter mast keeps you out of the way of the bottom. The AF85 gives you more ride height to clear waves and heel over into tighter turns, and it's the more forgiving choice in rougher water. Both use the aluminium AF Board Adaptor, engineered with strength where stresses concentrate with the same GeoLock connection for a direct feel between board and foil.

Everything in the set is built to work with anything else in North's Sonar range. Add any Sonar front wing to complete your setup, then expand from there: swap fuselages, stabilisers or mast as your riding develops without needing to replace what you've already got.... until you get woo'd by Carbon!

Key Features

  • GeoLock connection: a tapered geometry locking system between mast and fuselage
  • AF72 mast: suited to shallow water and prone surf foiling
  • AF85 mast: more ride height for choppy conditions and tighter turns, forgiving in rougher water
  • AF Board Adaptor: fully engineered aluminium
  • A700 Fuselage: 700mm length, delays the pitching moment for greater stability, ideal for learning to foil or wing foiling
  • S270 Carbon Stabiliser: for clean, undisturbed hydrodynamic flow
  • Industry-standard 165x90mm US Track bolt pattern: works with North's DropBox mounting system for a wide adjustment range, so you can precision-tune the setup to your weight
  • Sonar Travel Bag: heavy-duty 600D padded bag, for your AF setup with clipped and Velco straps, clips along with interior pockets to keep everything secure with space for extras.

NB. Front wings are sold separately, and foil-to-board Track Nuts and Bolts mounting hardware isn't included
