Ajuy Wing Foil Adjustable Harness Line (Red) Strong Dyneema, Universal Mount

Use case

If you ride wing foil with a harness, a good harness line quickly becomes one of those “why didn’t I do this earlier” upgrades. The Ajuy adjustable harness line is designed to transfer the wing’s pull from your arms to your harness, so you can ride longer, stay more relaxed, and keep cleaner control when powered up.

This is a universal-mount wing foil trapeze line that works with most wings, whether you ride a boom, hard handles, or soft handles. The attachment method is simple and familiar to anyone coming from kitesurfing: you create a loop and secure it on the knot system, so the line sits where you want it and stays there.

Ajuy’s “AJUY” line collection is known for being thicker, which makes it stiffer. That extra rigidity helps the line keep its shape, making hook-ins smoother and reducing the annoying “floppy rope hunt” when you want to connect quickly. On top of that, it comes in several color options; this version is a clean, high-visibility red that’s easy to spot on the wing.

Main benefits

• Adjustable length via knot system: fine-tune your hook-in position and feel on the water without overcomplicating your setup.
• Universal mount: works with most wings and common handle/boom configurations using a simple loop-style attachment.
• Premium Dyneema line: chosen for low stretch and reliable performance when the wing loads up in gusts.
• Stiffer, thicker AJUY build: holds shape better, making it easier to hook in and more stable while riding.
• Comfortable, practical finish: the line sits neatly, stays manageable, and is built for real use rather than showroom looks.
• Distinct red colorway: quick visual check of your rig and a nice match for bold wing setups.
