Radar Vapor Lithium Slalom Waterski – 2026
The Vapor Lithium is the workhorse of the Vapor line—and for a lot of skiers, it’s the sweet spot.
It shares the same shape as Radar’s Pro Build, so you’re getting the exact same platform that’s proven at the highest level. Where it differs is in the construction. The Lithium uses a machined PVC core, a material that’s become the standard for consistent, high-performance feel across the industry.
What that means on the water is simple:
It’s smooth, predictable, and fast—but not overly demanding.
Whether you’re running 39’ off or just getting in more free ski sets, the Lithium gives you a ski that responds the way you expect it to, turn after turn.
What Changed for 2026
Radar didn’t reinvent the Vapor—they refined it.
For 2026, the focus was on improving how the ski moves into and through the turn. The relationship between the tunnel rocker, bevel rocker, and tip height has been smoothed out, creating a more balanced platform from the front of the ski all the way through the tail.
The result:
- Cleaner, more controlled turn initiation
- More consistent speed from apex to edge change
- A ski that lets you stand where you want without fighting it
You can be aggressive when you want to be—but the ski doesn’t punish you if you’re not perfect.
On the Water
This is where the Vapor Lithium really separates itself.
The updated tip engagement allows you to bring more of the ski into the turn without feeling like it’s going to over-rotate or stall. Water flow is more controlled from the tip through the forebody, which helps the ski carry speed evenly through the entire turn.
A balanced tip leads to a stable, supportive tail—so when you move, the ski moves with you. The fin stays engaged, and everything feels connected.
Bottom line:
It builds confidence.
Feature Spotlight: Attitude-Control Tunnel
One of the biggest focuses in the redesign was improving water flow from the very front of the ski.
By dialing in the relationship between the top rocker and tunnel rocker, Radar created a more predictable platform as the ski enters the turn. That means better stability when you need it most—and more control when you’re pushing harder.
