Radar Union Water Ski

The Radar Union Water Ski is crafted for skiers who want stability, ease of use, and reliable performance—particularly in open water settings. Designed with a shape that is four tenths of an inch wider than the Vapor, the Union delivers a broader platform that enhances balance and increases confidence, especially for those progressing in their technique. This added width offers more surface area, making it easier to stay on top of the water and manage transitions with control and precision.

Built to perform exceptionally well at speeds ranging from 24–32 MPH, the Union accommodates a wide range of skill levels. Its versatility makes it ideal for both casual riders and those looking to refine their slalom skills in a relaxed setting. By blending a forgiving core with responsive materials, this ski allows you to enjoy extended sessions on the lake without compromising on ride quality or turning capability.

Key Features

• All-Terrain Core – The Union features Radar’s most forgiving construction, designed to smooth out the ride and reduce fatigue over time. This core helps dampen vibrations and stabilize the ski in variable conditions, making it easier to maintain consistent turns and balance throughout longer runs.
• 100% Carbon Fiber – With a full carbon fiber wrap, the Union maintains a reliable and consistent flex every time you ride. Carbon construction enhances durability and responsiveness while keeping the ski lightweight and agile on the water.
• Increased Width for Stability – At four tenths of an inch wider than the Vapor, the Union’s extra width adds noticeable stability and control. This helps skiers ride confidently at slower speeds while still allowing room for technical progression and smooth edge transitions.
• Optimized for Open Water – The Union is purpose-built for skiers who enjoy open water sessions. Its stable platform and forgiving characteristics make it an ideal choice for recreational slalom skiing, with performance that adapts to both calm and slightly variable conditions.
• Versatile Speed Range – Best suited for skiing between 24–32 MPH, the Union supports a wide range of rider styles and abilities. Whether you're refining your turns or enjoying laid-back laps around the lake, this ski offers control and comfort from start to finish.

Shape

The Union follows suit with our design methods by being four tenths of an inch wider than a Vapor. This extra width gives skiers the chance to feel ultimate balance while learning to ski at a higher level. We challenge you to find a ski that is more fun to ride in open water.

Tip Rocker

Starting the tip rocker directly at the end of the flat spot gives the ski more fluidity and makes the transition from turning to pulling seamless. More rocker in the tip helps the finish of the turn happen more quickly and with more stability.

Flat Spot

The flat spot is your balance point, by making this point right at the toes of your front foot you get a balanced place to stand at every single turn. This balance allows you to stand with confidence and make symmetrical turns on both sides of the course.

Straight Lines

Our unique straight lines allow the ski to be the fastest on the market. The lack of outside radius decreases drag and lets the ski flow with ease from side to side. In turn, you’re getting more cross course speed than any other ski on the market.

Rocker

Rocker defines the pivot point on a ski; we’ve moved that contact point closer to the ball of your front foot, which helps the ski pivot easier. The tight radius quick turns are then balanced with our tail rocker which adds support off the buoy, giving you the ability to build more speed from a wider point.

Edge Angle

At four tenths of an inch wider than the Vapor the width of the Union creates ultimate stability. This bigger overall profile allows a skier to ski in control without the risk of the ski rolling too far on edge and making them lose their balance.
