Artness PRO V2 Retractable Harness Line

The Artness PRO V2 Retractable Harness Line is a wingfoil-specific harness line made by A3D Sport, a French brand focused on retractable harness line systems for wing foiling. The PRO V2 — also referred to as the Artness Pro 2 — is the second generation of A3D's flagship harness line, building on the original Artness PRO with a refined design and updated hardware. It attaches to a wing's central strut and allows riders to hook into their harness for powered flight, then retract the line flush against the strut when unhooking for maneuvers or transitions.

The core concept is adjustable line length on the fly. While hooked in, a rider can shorten the line for more direct control during upwind tacks or extend it for added stability when bearing off or dealing with gusty conditions. The retractable mechanism keeps the line taut against the strut when not in use, eliminating the loose, dangling lines associated with fixed harness setups.

• Line material: Dyneema® 5mm (polyethylene fiber, rated approximately 15 times stronger than steel in tension and abrasion resistance)
• Attachment: Velcro® 30mm hook-and-loop straps (rated at 330 lbs tension resistance per turn on the handle)
• Structural components: PETG plastic, 100% FDM-printed
• Compatibility: All wing types — soft handles, hard handles, and wishbone/boom configurations
• Leash note: Not compatible with coiled wing leashes; a straight wing leash is required

The Artness PRO V2 suits intermediate to advanced wing foilers who want the efficiency of a hooked-in riding position without sacrificing the freedom to unhook quickly. Riders covering distance, racing, or sailing in variable wind will benefit most from the ability to adjust line length mid-session. The system has seen use in both race and freestyle contexts, so it spans a broad range of riding styles rather than targeting a single discipline.

Beginners still learning board starts and basic wing handling will likely find a fixed harness line — or no harness line at all — simpler to manage. The Artness PRO V2 adds the most value once a rider is comfortable flying on foil and wants to reduce arm fatigue over longer sessions or optimize body position for different points of sail. A3D recommends pairing it with a harness that uses a plastic hook rather than metal, as metal hooks can accelerate wear on the Dyneema line.

A3D Sport's range centers on the Artness retractable harness line concept, offered at multiple price and feature tiers. The Artness V2 sits below the PRO V2 as a more affordable entry point into the retractable system, while the PRO V2 represents the top of the line with improvements introduced over the original Artness PRO. Those updates include a streamlined two-strap Velcro attachment (down from the previous design), a flexible base for improved grip and handle protection, integrated risers, and a revised cleat stopper oriented toward racing use.

In the broader market, fixed harness lines from brands like Mystic and Dakine remain the conventional choice, making the Artness PRO V2 a distinct alternative for riders specifically seeking adjustable, retractable functionality. Buyers choosing between the standard Artness V2 and the PRO V2 are primarily weighing the upgraded hardware and racing-oriented refinements against the price difference.
