Duotone Foil Assist Set D/LAB

The Duotone Foil Assist Set D/LAB is the premium Duotone Foil Assist setup. The lightest, strongest and sharpest way to run an electric assist system.  Designed and made for riders who want boost and feel. The carbon D/LAB mast is slimmer, stiffer and has lower drag than anything else in the range, so between bursts of power you're riding something that turns and glides like a proper high-end foil.  Small waves, big waves, or bumps on a downwinder, this is the one that keeps up when the riding gets serious.

The set is the whole system: the carbon eMast D/LAB, the eHarness carrying the batteries, the watch and ring remote, the batteries and the charger. All you add is your foil, and that comes with a catch worth reading before you buy.

Worth noting: the D/LAB's 3BS connection is moulded straight into the base plate, so it runs Duotone foils only, or Armstrong foils using Duotone's dedicated fuselage. If your foil is Axis, Lift, Gong, F-One or anything else, the aluminium Foil Assist Set AL is the one that will fit, since it takes an adapter and covers most brands.

Performance & Feel

The assist drive itself is so easy to use.  Press for power and the folding propeller opens instantly and drives you onto foil, then it folds shut and you're back to riding. Touchdowns and landings barely register, which is where that super slim mast and built in base plate earns its money.

The feel is all about the numbers underneath you. At 3kg it's lighter than the aluminium mast, with a 110mm chord against 120mm and 14.5mm at its thinnest point against 18mm, so there's simply less mast in the water. The motor pod is moulded into the profile 17cm below the top plate and cables run internally. Shaped to shed drag while you pump, land and touch down. The batteries sit on your waist/hips on a buoyant harness, so the board itself carries nothing extra, and the receiver lives in the battery box lid where water can't interrupt the signal.

Duotone quote 25 to 40 minutes of runtime and for best battery life they suggest a front wing of 900cm² or more with a board of at least 35L. Every component is cross-compatible across all eMast options, so parts can be moved between systems easilly.
