Description

If you already foil and you’re chasing more “good sessions” in real-world UK conditions, the Duotone Foil Assist Set AL is one of the cleanest ways to add electric help without turning your setup into a full eFoil. The motor is integrated into the mast, the batteries sit on your waist, and the result is simple: earlier take-offs, longer links, and a safety margin when the wind or swell drops off.

Where it sits in the range

Foil Assist Set AL is the smart, value-led choice: durable aluminium mast, low drag feel, and the same core experience that makes the Duotone system so appealing. If you’re chasing the absolute lightest swing weight and premium stiffness, step up to the Foil Assist Set D/LAB 2026. If your priority is relaxed cruising and extra reassurance (including a prop guard), look at the Foil Cruise Set AL 2026. Want the easiest “it just works” route with a matched board + foil? Go straight to the Foil Assist Set Complete AL (incl. Board) 2026.

Why riders choose Foil Assist

  • More take-offs: cheat marginal wind starts, flatwater pump-ups, and weaker swell entries.
  • Longer connections: link bumps, waves, and runs that would normally die between sections.
  • Less “waiting around”: spend more of your session flying, not slogging back upwind or paddling.
  • Confidence + safety margin: a helpful boost to get home if conditions soften.
  • Cleaner than pod systems: the motor-in-mast approach keeps the board underside tidy and glidey.

We’ve put together a proper, real-world breakdown of how the Duotone system feels, where it shines, and who it’s best for.

Compatibility & what you’ll need

  • You will need a foil and board: this is the assist system only (not a complete board + foil package).
  • Board mounting: works with boards that have standard twin US foil tracks.
  • Fuselage adapter required: you’ll need the correct adapter to marry the Foil Assist mast to your foil brand (sold separately).

Choose your adapter (sold separately)

If you’re unsure which adapter you need, message us a photo of your current fuselage connection (or tell us your foil model) and we’ll point you at the right one.

Helpful reading & buying advice

FAQs

Is this a full eFoil?

No — it’s an assist system for foiling. You still ride it like a foil (wing, prone, SUP, downwind, parawing). The power is there to help you take off, connect, and get home — not to replace the feel of foiling with a dedicated eFoil board.

What’s the difference between Foil Assist AL and D/LAB?

AL is the robust, value-led aluminium mast option. D/LAB is the premium carbon option aimed at riders who want the lightest swing weight and stiffest feel. If you’re unsure, AL is the safe place to start for most riders.

Do I need a special board?

You’ll need a foil board with standard US twin tracks. Beyond that, it’s about matching volume and shape to your discipline. If you want a board designed around Foil Assist take-offs, have a look at the Duotone Midfish 2026 or the Complete AL package.

Which harness size should I choose?

S–M: 28–35" waist (71–89cm)
L–XXL: 35–45" waist (89–114cm)
If you’re between sizes and plan to wear it over a thick winter wetsuit, sizing up is usually more comfortable.

How long does it run for?

Think 35–60 minutes of assisted use, depending on rider weight, board/foil efficiency, and how hard you lean on the power. Most riders use it in short bursts — take-off help, connection help, then back to glide.

Can I fly with the batteries?

The battery format is designed around common airline capacity limits, but airlines vary and rules can change. Always check your airline’s current lithium battery policy before you travel.

What do I need to make it compatible with my foil?

You’ll need the correct Adapter Fuselage for your foil brand (sold separately). If you tell us your foil model (or send a photo of the fuselage connection), we’ll point you to the right adapter.

Need a hand choosing the right setup?

Tell us your weight, your discipline (wing / prone / SUP / downwind), your current board volume and foil model, and we’ll recommend a sensible starting point — including the right adapter and a setup that suits UK conditions.

Specifications

  • Features

    Integrated 84cm Aluminium eMast

    The motor is housed within the mast profile itself rather than in a separate pod. On the water, this means significantly less drag and a much cleaner look. The 84cm height is the "sweet spot" for most riders, providing enough clearance for carving through chop without feeling disconnected from the foil's lift.

    eHarness Waist Battery System

    By carrying the battery weight on your body using the Duotone eHarness Waist Belt, your board remains a "pure" foilboard. The harness is buoyant and non-water-absorbing, so it doesn't get heavy during a session. It connects to the mast via a slim, magnetic quick-release cable that ensures you are never "locked in" to the board.

    eRemote Watch Ring

    Control is handled by the Duotone eRemote Watch Ring Set. This waterproof smartwatch-style unit paired with a finger-mounted trigger allows you to paddle, duck dive, and handle a wing normally while still having instant access to seven levels of boost.
