Duotone Foil Assist Set AL

The Duotone Foil Assist Set AL is a complete electric assist system that hands you a burst of power exactly when you want it. Instead of paddling yourself to exhaustion hunting for the one wave that works, you can pick your moment, take the boost and go. It turns marginal days into proper sessions, makes linking waves realistic, and opens up downwind runs that fitness alone would rule out.

Everything you need is here bar your foil set itself: the eMast AL (Aluminium), the eHarness that carries the batteries, the watch and ring remote, the batteries and the charger. One thing to order separately though, is the fuselage adapter, which isn't included. Duotone make their own plus ten other options covering most foil brands, so your existing wing set and fuselage will almost certainly bolt on, but you'll need the right adapter to do it.

Worth Noting: Even if you have a Duotone foil set up, you will still need the Duotone mast to fuselage adapter. 

Performance & Feel

What stands out is how little the assist interferes with the foiling. The batteries ride on your waist/hips rather than bolted to the board, so the board feels, turns and pumps the way it always did.  The harness is buoyant and is easy to take off when you have finished your session. Press for power and it comes in smoothly through the folding propeller, enough to get you up and onto foil without a frantic paddle, then the props fold away and you're just foiling.

The aluminium mast is genuinely stiff, with a rigid surf-inspired profile that puts your input straight through to the foil so feels direct and because the motor pod is moulded into the mast 17cm below the top plate and set slightly behind the leading edge, there's no bolt-on hardware dragging in the water to blur the feel. Even touchdowns stay clean. The remote is a waterproof watch paired with a finger ring, so both hands stay free for paddling, pushing up or handling a wing and the receiver sits in the battery box lid where water can't cut the signal.

Every part is cross-compatible across the eMast options too, so moving up to carbon later means changing the mast, not the whole system. For best battery life Duotone suggest pairing it with a front wing of 900cm² or more and a board of at least 35L.
