Radar Senate Lithium Water Ski 2026

The Senate series pours fuel on your slalom ski fire. Proudly, it is the most widely heralded, highly regarded shape in our line, simply because it works so well across a wide spectrum of skiers. We start with our new Vapor shape and mindfully add two tenths of an inch in extra width between the tunnel and the edge bevel. As opposed to simply scaling the ski wider, this keeps the active wet surface the same as the Vapor, meaning it’s going to turn and grip like a Vapor does. Lightning fast where it needs to be and controlled through the turn, we have found the ideal surface area and shape for flat out performance at slightly slower speeds. From the seasoned veteran looking to get back to their prime, to the 34 MPH competitor looking to conquer new line lengths, the Senate Series has a model that will have you rethinking the limits of your personal waterski goals.

The Senate Lithium is Radar's most versatile ski in the line. With the efficient energy-transferring properties of PVC foam and spread tow carbon, the Li can get it done at the shortest shortline, and is still easy enough to control for an open water cruise. If you do not know which ski in our line fits you best, chances are high it’s the Senate Lithium.

FEATURE FUNCTION SPOTLIGHT

Performance Width
Where we add surface area to the Senate series is the backbone to bridging ease of use, with flat-out performance. As opposed to simply scaling a Vapor wider we start with its active wet surface (the tunnel and edge bevels) and leave them relatively intact. From there we build surface area by adding a one tenth of an inch rail between the outer edge of the concave and the bevel. This small rail creates lift and support at slower speeds without sacrificing the ski’s roll, grip and drive through the wakes. This allows you to slow the boat, without slowing your ability to attack the water.
