Duotone Electric Foil Assist D/LAB 84cm Set

Prone Foiling / Downwind / Wake Foil / Wing Foil

Mast Length: 84 cm
Harness Sizes: S/M – L/XXL

The Foil Assist Mast D/LAB Set represents the pinnacle of assisted foiling performance. Built for riders who demand the lightest weight, lowest drag and most precise control possible, this mast combines Duotone's Mast Slim 2.0 D/LAB High Modulus Carbon construction with a seamlessly integrated assist motor.

Ultra-light, incredibly rigid and engineered for maximum efficiency, the D/LAB mast delivers unmatched glide, instant response and effortless takeoffs across prone, downwind, wake and wing foiling. This is assisted foiling at its most refined.

Key Features & Performance Benefits

Seamless Integration for Ultra-Low Drag
The fully integrated motor pod, positioned 17 cm below the top plate, along with internally routed cables creates a clean, hydrodynamic profile. This reduces resistance, improves glide and preserves the natural feel of unassisted foiling.

High Modulus Carbon Construction
Built from premium High Modulus Carbon, the Mast Slim 2.0 D/LAB is Duotone's lightest and most advanced assist mast, for lightning-fast response, superior efficiency and effortless control at all speeds.

Extremely Low Drag Profile
A super-slim mast and base plate design minimize drag during pumping, touchdowns and landings. Whether accelerating onto foil or carving at speed, the D/LAB mast stays fast, smooth and efficient.

Pro-Level Rigidity & Precision Turning
Tested and approved by Duotone's Pro Team, this is the stiffest mast in the lineup. The extra rigidity gives precise turning, instant feedback and playful, high-performance handling, especially in powered maneuvers and tight arcs.

Powerful Thrust for Earlier Takeoffs
A high-torque motor producing up to 33 kg of thrust gets you flying sooner with smaller foils and boards, for sharper responsiveness, quicker acceleration and total control in marginal conditions.

Folding Propeller for Speed & Safety
The folding propeller only opens and spins when powered, eliminating drag during glide phases while adding safety during falls.

Reliable Signal & Consistent Power Delivery
With the receiver housed in the eHarness battery box, signal strength stays solid and uninterrupted for smooth, dependable propulsion and precise throttle response every session.
