Duotone Electric eHarness Set
The Duotone Foil Assist eHarness stands out for its low weight, perfect balance, and maximum freedom of movement. Unlike traditional systems that place batteries on the top of the mast or inside the board, the Duotone Foil Assist positions the two batteries (2 × 1 kg) in a waterproof box attached to a comfortable waist harness. This solution delivers three major advantages:
- Keeps the board + foil setup perfectly balanced, even with the added motor.
- Preserves 100 % of the pure, natural foiling feel.
- Avoids the main drawback of battery backpacks: weight on the shoulders that throws off balance during turns and quick maneuvers.
With the eHarness, the total weight of just 3.76 kg (box + 2 batteries) rests on your hips, so it never affects balance, leaves your upper body completely free, and after a few minutes you’ll hardly notice you’re wearing it.
Clean and secure connection: the power cable exits the box and runs protected inside a short leash up to the top plate of the mast. The board safety leash attaches underneath the cable port, directly to the harness box itself.
Integrated receiver = rock-solid connection. The Bluetooth receiver for the remote is mounted on the box lid, above the water, guaranteeing 100 % reliable signal at all times.
