Radar Union Water Ski 2026

Radar Union Water Ski

The Radar Union Water Ski is built for skiers who want strong slalom performance at slightly slower boat speeds. Designed to get up quickly and roll smoothly onto edge, the Union blends easy deepwater starts with the lively carving feel of a performance ski. By maintaining a performance-focused active wet surface while adding additional surface area outside of the tunnel, the Union planes effortlessly and delivers confident edge control once you're up and moving.

Using Radar’s universal design approach, the Union begins with the proven Vapor shape and strategically adds four tenths of an inch of width outside of the concave, between the tunnel and the bevel. This preserves the ski’s ability to roll and grip like a high-end slalom ski while providing the extra lift and support needed at lower speeds. The result is a ski that feels stable and forgiving on starts yet powerful and responsive through aggressive turns.

The Union also features Radar’s High-Speed Flow Line design, using straight outline lines from the wide point through the tail to increase waterflow efficiency and reduce drag. This allows the ski to move quickly and smoothly from one side of the wakes to the other, delivering a fast, flowing feel even when the boat speed comes down.

• All-Terrain Core - Radar’s most forgiving construction delivers a stable ride with smooth, predictable response.
• 100% Carbon Fiber - Carbon laminates provide consistent flex and lively performance.
• Terrain – Crossover - Designed to perform across a range of conditions from open water carving to course-style skiing.
