Duotone Foil Assist Mast D/LAB 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. The result is 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 increased rigidity translates into precise turning, instant feedback, and playful, high-performance handling—especially noticeable in powered maneuvers and tight arcs.
Highly Modular System Compatibility
The Foil Assist Mast D/LAB allows seamless swapping of motors and connector cables across the entire Assist mast range. It’s compatible with Duotone 3BS fuselages, Tail D/LAB, SLS and D/LAB wing sets, and connects to Armstrong foils via a dedicated fuselage. Mounts easily to any brand’s prone or wing board.
Powerful Thrust for Earlier Takeoffs
Driven by a high-torque motor producing up to 33 kg of thrust, the D/LAB mast gets you flying sooner with smaller foils and boards—unlocking sharper responsiveness, quicker acceleration, and total control in marginal conditions.
Folding Propeller for Speed & Safety
The folding gear propeller only opens and spins when powered, eliminating unnecessary drag during glide phases while enhancing safety during falls and water contact.
Reliable Signal & Consistent Power Delivery
With the receiver housed in the harness battery box, signal strength remains solid and uninterrupted. Expect smooth, dependable propulsion and precise throttle response throughout every session.
