Radar Lithium Vapor Water Ski 2024

The Radar Lithium Vapor Water Ski 2024 brings world-class performance within reach for skiers who want elite-level design without the top-tier price tag. Built using the same high-performance mold as Radar's Pro Build Vapor, the Lithium model carries the same trusted shape that has powered pro skiers to victory—but with construction optimized for value and longevity. Designed specifically for the slalom course and tuned for speeds between 30–36 MPH, the Lithium Vapor delivers incredible edge hold, aggressive turning radius, and seamless speed through the wakes. It’s fully capable of running anything from 15 off to 41 off, giving ambitious skiers a responsive, forgiving platform to push their limits.

At the core of the 2024 Lithium Vapor is Radar’s tried-and-true PVC core—a lightweight, closed-cell material known for its unmatched durability, consistent rebound, and excellent energy return. This is the same foundational tech trusted in high-end skis for decades. The ski is wrapped in Sigmatex carbon fiber, bonded with an eco-conscious bio resin system, and finished with a race-ready base for maximum glide and early turn initiation. From intermediate slalom skiers looking to elevate their technique to advanced riders running shorter lines, the Lithium Vapor provides the perfect blend of precision, performance, and value.

Key Features:

• PVC CORE – Tested and proven response. Radar’s PVC core has long been favored for its lightweight feel and reliable flex. It offers a firm yet forgiving ride that responds quickly to skier input, making it ideal for high-performance carving and consistent line tension through every pass.
• SIGMATEX CARBON – Consistent flex every time. This premium carbon fiber material delivers a strong, lightweight frame with unmatched torsional control. It ensures each turn feels fluid and each transition smooth—allowing the ski to maintain balance, speed, and predictability at varying rope lengths.
• BIO RESIN – Plant based and better. Radar’s plant-based resin system offers an eco-friendlier alternative to traditional composites, improving vibration dampening and strength while reducing environmental impact. It's better for your ride and better for the planet.
• RACE BASE – Earlier lines and easier turns. The Race Base is built for low-drag, high-speed performance, allowing the ski to move effortlessly across the wakes and engage earlier in the turn. It supports fast, reactive skiing with enhanced acceleration out of the turn.
• ENDURO TIP/TAIL – Built for speed. Reinforced tip and tail sections improve tracking and durability, helping the ski remain stable at high speeds and under aggressive edge pressure. It keeps you locked into the line from turn entry through wake exit.
• RADAR LAB MADE – Thanks Herb. Built and refined at the Radar Lab—home of world-class water ski innovation—the Lithium Vapor is a product of decades of design evolution, professional feedback, and race-tested geometry. It’s the result of passion, precision, and relentless pursuit of performance.

Optional Binding: Vector BOA

For skiers who demand comfort without compromising on performance, the Radar Vector BOA Binding is the perfect match for the Lithium Vapor. Designed for precision and all-day support, the Vector BOA combines Radar’s proven Feather Frame chassis with the industry-leading BOA® Fit System for customizable micro-adjustments on the fly.

The BOA system allows skiers to dial in a secure, uniform fit with the twist of a knob—eliminating pressure points and improving overall comfort. The asymmetrical design of the Vector BOA supports natural foot alignment, while the dual-density footbed absorbs vibration for smoother rides. Whether you're setting PBs in the course or free skiing with intensity, the Vector BOA binding ensures your foot stays locked in and your energy transfers directly to the ski.

With the Radar Lithium Vapor Water Ski 2024, you're getting high-end course performance at a more accessible price point. Add the Vector BOA binding for unmatched comfort and performance, and you'll have a setup capable of delivering elite results every time you're behind the boat.

Shape
The wide spot on the ski has moved forward and width has been added from the middle of the ski through the tip. This gives the ski a more tip to tail taper and more support through the front part of the ski. The increase in taper presents the ski with a slightly more tip-up riding attitude and allows the ski to pull through the turn in a more connected, powerful way. The result is less body movement needed to get tight radius turns. The new ski also has slightly less volume in the tail. By reducing this surface area, the tail of the ski is able to smear outward while also staying planted in the water. Ultimately, the updates in shape help it to ride much closer to the ideal line for any given speed and rope length.

Rocker
The tip rocker on the new Vapor starts just after the wide spot. This relieves tip pressure and increases forgiveness, allowing a skier to have a bigger platform to stand on coming into the turn. This also helps keep the ski keep moving outbound in the transition and makes the ski incredibly more predictable in the turns it creates. Moving back from the wide spot, the rocker lines are all new. These new lines create a ski with increased tail rocker which softens the way the ski rotates or carves through the turn. The result is a feeling of increased angle from a wider place with an instant acceleration.

Concave
The additional concave depth running throughout the bottom of the ski is one of the most noticeable differences in this new shape. This channels more water directionally from tip to tail, resulting in significantly more side-to-side drive and holding power. More drive and hold allow a skier to be faster as they near centerline which results in a more up-course path. Another result from an increased concave is increased pressure on the bevels, allowing the ski to feel extremely connected to the water. This gives a skier the freedom to control the path of the ski with more ease.

Bevels
The front of the ski carries a sharper, more angular bevel design to harness the increased water flow from the new concave design. This gives the skier more ability to feel how the water interacts with the tip of the ski to create sharper, more predictable turns. In the tail of the ski, the bevel is softened, allowing the water to wrap around the bevel easier. The tip of the ski pulls harder through the turn while at the same time, the tail is able to smear while staying planted in the water. This feathered approach makes the turns feel much more natural and less forced.

Thickness
Sidewall height carries constant to provide balance for the increased lift created by adding width. In an effort to keep the ski nimble, sidewall thickness is reduced to produce the connected, tight turning radius of the ski.

Edge Angle
The Vapor width allows the ski to achieve maximum edge angle both in the turn and while cutting. This width sets the precedent in our line as the pinnacle of performance both in the course and while free skiing.

The Vector Boa packs a punch. Featuring Carbitex CX6 strips to give you ultimate response and a Boa reel to dial in your fit perfectly every time. You’ll be wondering where this boot has been your whole life.

Technology

Feather Frame Chassis
The Feather Frame Chassis stands on a pedestal as the only boot system to completely integrate the mounting system, baseplate and outer shell into a single component. This allows you to stand closer to the ski and offers a better connection.

Carbitex
Carbitex is a carbon fiber textile material that is more reactive than any other material on the market. This reactivity translates into an unparalleled connection to the ski.

Boa
The Boa integration into the boots offers an instant response found only in the Radar line. Transform your experience through a fast, customizable, and comfortable fit.

Intuition
Our exclusive partnership with Intuition gives you a heat-moldable, lightweight, pre-formed fit. Intuition foam ensures you have a perfect fitting liner for ultimate performance.

Wrap Tech
Wrap Tech fuses the external skeleton of the boot to the base textile layer which gives the boot the ability to conform to the shape of your foot, in turn giving you more response.
