High Speed Crossover Water Ski With Easy Power

This Water Ski Is Best For:

  • Weekend Cruisers: Added surface area makes deep-water starts effortless, helping every rider get up smoothly and enjoy relaxed laps.
  • Edge Masters: Width added outside the tunnel lets the ski roll onto edge like a pro model, giving you confident bite and aggressive carving at slower speeds.
  • Performance Junkies: High-Speed Flow Line design reduces drag for fast side-to-side acceleration, keeping your turns quick, clean, and addictively powerful.
  • Family Riders: Stable, predictable handling makes it the perfect shared ski for fun sets, new skiers, and memory-making days on the lake.

The 2026 Radar Union Water Ski blends Vapor-inspired DNA with a wider, more forgiving platform that thrives at 24–32 mph. By adding width outside the tunnel, the Union maintains true performance edge engagement while giving you easier starts and a smoother, more stable ride. Its High-Speed Flow Line uses straighter outline geometry for efficient waterflow, reduced drag, and impressive acceleration from wake to wake. For open water fun, crossover carving, or glassy morning sets, the Union delivers a lively, easy-riding experience rooted in Radar’s passion for skiing and good times on the lake.

THE BASICS

When choosing a radar ski, there are so many factors to consider. Where should you start?

  • EXPERIENCE LEVEL
    Whether you're beginner, intermediate, or advanced, there is a ski for you.
  • SKI PROFILE
    The height and width of the ski all change how it will ride on the water.
  • CONSTRUCTION
    Radar uses nothing but the best materials for each and every ski.
  • WATER TYPE
    Skis for ripping it up on the course, and skis for carving out in open water.

CONSTRUCTION MATERIALS

  • PMI

    PMI Foam is leading the industry as a core with its lightweight, reactive qualities. More speed and instant connection is how that translates on the water.

  • PVC

    PVC has been an industry staple for well over a decade. It is trusted and proven as a core because of its long-lasting strength and quick response.

  • AERO CORE

    AeroCore is our exclusive formulation of polyurethane foam. With an amazingly high strength-to-weight ratio these skis sit deeper in the water for a forgiving, consistent ride.

  • ALL-TERRAIN CORE

    Our All-Terrain Core is the most forgiving construction we offer. A polyurethane core with paulownia wood stringers allows the ski to cross the wakes with ease.

  • TEXTREME

    Textreme is a manufacturer of spread tow carbon which allows us to reduce weight and increase strength. It most importantly provides us a more consistent flexing and durable ski.

  • INNEGRA

    Innegra is a dampening fiber that reduces vibration and increases strength. Innegra is woven into the Textreme to improve the performance and durability of the ski.

  • SIGMATEX

    Sigmatex is an industry leader in the carbon fiber world. Their looming process is computer controlled giving them the ability to use ultra-high modulus carbons with complete precision.

  • NFC ENABLED

    Putting Technology in the ski. An NFC Chip allows the consumer to get more information about the ski with just a touch of their phone.
