Foil Drive NORTH Sonar Integrated UHM80 Mast — No Motor
An ultra-low drag North UHM carbon mast built for cleaner Foil Drive integration, faster lift, and a more direct ride feel.
The Foil Drive NORTH Sonar Integrated UHM80 Mast is a high-performance upgrade for riders who already have a compatible Foil Drive V2 motor and want the cleanest North Sonar integrated mast setup. Built from Ultra High Modulus carbon, the UHM80 is designed to reduce drag, improve glide, sharpen turning response, and make electric-assisted surf, downwind, and open-water foiling feel more efficient.
- Mast Only — No Motor Included
- Ultra High Modulus Carbon
- 80cm Mast Length
- Integrated Motor Pod + Wiring
- V2 Standard / High Power Compatible
- North Sonar Compatible
Important: This product is the mast only. It does not include the Foil Drive motor, battery, controller, complete Foil Drive kit, board, Sonar front wing, fuselage, or stabilizer.
Why Upgrade to the North UHM80 Integrated Mast?
Less Drag, More Efficient Riding
The UHM80 uses a thinner, lower-drag profile designed to help riders accelerate onto foil faster and glide more efficiently once flying. For Foil Drive riders, that means less wasted energy and a cleaner feel underfoot.
Integrated Motor Pod Design
The motor pod is faired directly into the mast for a smoother hydrodynamic shape. The fixed 18cm pod position balances propeller immersion for assist while keeping the motor high enough to reduce interference once you are on foil.
Direct, Responsive UHM Carbon Feel
Ultra High Modulus carbon construction gives the mast strong torsional and bending stiffness, helping translate rider input into a more precise, connected foil response.
Built for Surf, Downwind, and Assist
At 80cm, the mast gives a versatile ride height for assisted prone, surf, downwind, and open-water foiling without feeling oversized or sluggish.
Tech Features
Ultra-Low Drag Profile
The UHM80 mast is 25% thinner than the AF80 FD mast and uses a 14% shorter chord length, helping reduce resistance through the water for faster acceleration and improved glide.
108mm Chord for Quick Turns
A shorter 108mm chord supports increased maneuverability, giving the mast a faster, more responsive turning feel for surf lines and tighter carving.
13.5mm Mast Width
The slim 13.5mm profile is designed to cut drag and improve efficiency, especially important for riders trying to extend battery range and maximize glide.
Pre-Installed Foil Drive Puck
The Foil Drive puck is pre-installed into the motor pod with integrated internal wiring, creating a clean connection point for compatible V2 motor systems.
Fixed Motor Pod Position
The pod is fixed in position and cannot be moved or removed. This creates a purpose-built integrated layout instead of an external clamp-style motor setup.
GeoLock Connection
North’s GeoLock tapered geometry helps create a secure, load-bearing mast-to-fuselage connection for confident power transfer and reduced unwanted movement.
Recommended with Sonar Pro Carbon Fuselage
For the cleanest North Sonar performance setup, pair the UHM80 integrated mast with the Sonar Pro Carbon Fuselage and the Sonar front wing and stabilizer that match your riding style.
Compatible with V2 Motors
This mast is compatible with Foil Drive V2 Standard and V2 High Power motor systems that use the removable V2 plug connection.

Windance tip: Choose this mast-only option if you already own the correct Foil Drive V2 motor and want to move into the cleaner North integrated mast platform.
Compatibility Guide
Works With Foil Drive V2 Motor Systems
The UHM80 integrated mast is designed for compatible Foil Drive V2 Standard or V2 High Power motor systems. If your existing motor uses the V2 plug with removable cable, this mast is designed to work with that platform.
Recommended High Power Motor Pairing
For the strongest integrated setup, pair this mast with the Integrated Mast High Power Motor Set. For convenience, Windance also offers a mast + High Power motor bundle.
North Sonar Foil Platform
This mast is built for the North Sonar foil system and is recommended with the Sonar Pro Carbon Fuselage. Choose your front wing and stabilizer separately based on surf, freeride, or downwind goals.
Best with the North Boost Board
For a full North | Foil Drive setup, pair this integrated mast with the 2026 North Boost Foil Board, a compatible Foil Drive kit, battery, motor, and Sonar foil package.
