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

Use case

If you ride wing foil with a harness, a good harness line is the simplest way to get more time on the water with less arm pump. The Ajuy Adjustable Harness Line is designed to transfer the wing’s pull from your hands to your harness hook, so you can settle into a balanced stance, sheet in smoothly, and cruise upwind with less effort.

This model uses a universal mounting loop that works on most wings: soft handles, hard handles, and booms. The adjustment is done with knots, so you can quickly fine-tune the length to your body height, riding style, and wing size, even during a session once you feel where the “sweet spot” sits.

Compared to thinner, floppy lines, the Ajuy collection is made with a thicker, stiffer setup, which helps the line keep its shape and makes hooking in feel more consistent. It is also offered in multiple color options; this version comes in a clean blue that’s easy to spot when you are rigging or swapping gear on the beach.

Key benefits

• Adjustable length with knot system: dial in your preferred reach and hook-in point without tools, ideal for experimenting and finding your personal trim.
• Universal mount: simple loop attachment compatible with most wing handles and booms, inspired by proven connection logic from kite setups.
• Premium Dyneema line: low stretch and high durability for a direct feel, stable power transfer, and confidence when loading the wing.
• Stiffer feel thanks to the thicker construction: holds its shape better, making it easier to hook in and ride comfortably for longer tacks.
• Harness-friendly: works with common windsurfing and kitesurfing harnesses, so you can use the gear you already trust.
• Blue colorway: practical and good-looking, easy to identify in your kit and on the beach.
