Duotone eMast Assist Set AL 2026 – 84cm

Unlock more time on the water with the Duotone eMast Assist Set AL — the electric foil mast built for riders who want effortless takeoffs, longer sessions, and the freedom to ride with virtually any foil setup they already own.

At 84cm, this mast is purpose-built for prone and downwind foiling, but it's equally at home behind a tanker wake or in light-wind wing foiling sessions. The motor pod integrates seamlessly into the mast profile 17cm below the top plate, keeping the silhouette clean while internally routed cables eliminate drag and protect your lines from snags. The result is a mast that's as smooth and responsive as it looks.

The stiff, surf-inspired aluminum construction delivers direct, immediate feedback — no flex, no hesitation. You'll feel every input translate into confident, precise control whether you're threading a lineup or pumping back out after a long wave.

Dial In Your Boost Swap between plastic and aluminum propellers to tune your assist to match your style and conditions. Want to ride a smaller foil and carve tighter turns? Hit it with full power. Prefer a mellow lift for easy takeoffs and cruising? Soften the boost. The two-blade folding propeller folds flat on the wave for zero-drag glide, then deploys instantly via an integrated gear system the moment you need to power back out — no hesitation, no missed connections.

Built for Your Quiver, Not Just Duotone's Every component in the Foil Assist system is cross-compatible across all eMast options, so your investment grows with your setup. Compatible fuselage adapters cover ten additional brands including F-One, Armstrong, Gong, Axis, Lift, North, Code, Sab, AFS, and KT — and it mounts to any foilboard with standard US foil tracks just like a traditional mast.

For best battery performance, pair with a front wing 900cm² or larger and a board with at least 35L of volume.
