Ajuy Wing Foil Adjustable Harness Line Yellow, Strong Dyneema, Universal Mount

Use case

If you ride wing foil and want to take the load off your arms, an adjustable harness line is one of the simplest upgrades you can add. This Ajuy trapeze line is designed to transfer a big part of the wing’s pull straight into your harness hook, so you can ride longer, stay more relaxed, and keep cleaner technique when powered up.

The Ajuy line uses a universal mounting loop that works with most wings: soft handles, hard handles, and booms. The mounting method is similar to the well-known kitesurf “larks head” style connection: you form a loop and cinch it down, so it sits stable and doesn’t creep around during use.

Compared to many thin, floppy lines, the Ajuy collection is known for being thicker and therefore stiffer, which makes hooking in easier and more consistent, especially in choppy water or when you need to rehook quickly after a maneuver. On top of that, it comes in multiple color options; this version is a clean, high-visibility yellow, easy to spot when setting up or adjusting on the beach.

Key advantages

• Adjustable length via knot settings: tune the reach to your stance, arm length, and wing size, then refine it on the water until it feels natural.
• Universal mount for most wings: fits soft handles, hard handles, and booms with a simple loop connection, no complicated hardware.
• Premium Dyneema line: low stretch and high reliability, so the pull feels direct and predictable when you sheet in.
• Stiffer, thicker feel: easier hooking in and less “searching” for the line while riding, particularly when it’s windy or bumpy.
• Harness friendly: compatible with typical windsurfing and kitesurfing harness hooks, so you can use the setup you already own.
• Bright yellow visibility: quick to find during setup and makes small adjustments less fiddly.
