Radar Union Waterski 2025

The Union is the undisputed favorite around the Radar Headquarters due to its easy to ride ability without sacrificing any performance. Extra width allows you to ride the ski at slower speeds and improve at a rapid pace. This ski performs amazingly well between 24-32 MPH and will have you making endless turns on the lake all day long.

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.
