2024 Radar Lithium Vapor Water Ski

The 2024 Radar Lithium Vapor Water Ski is purpose-built for skiers who demand precision and consistency on the slalom course without compromising value. Crafted from the same mold as the elite Pro Build Vapor, this ski incorporates a robust PVC core that has long been respected for its durability and lively response. The Lithium Vapor blends high-end construction with accessible pricing, making it an excellent choice for serious skiers looking to progress their performance. Designed to excel in course settings at speeds between 30 and 36 MPH, this ski is ready to handle anything from relaxed free skiing to challenging 15–41 off passes with confidence and control.

• PVC CORE – The PVC core construction delivers a tested and proven response that experienced skiers trust. This material offers consistent flex under load and retains its structural integrity over time, resulting in a dependable feel as you accelerate, edge, and carve through every turn.
• SIGMATEX CARBON – Using SIGMATEX carbon fiber ensures that each ski maintains the same reliable flex profile session after session. This premium carbon weave provides excellent torsional stiffness and reduces unnecessary weight, translating into quicker edge engagement and smooth transitions across wakes.
• BIO RESIN – The Lithium Vapor incorporates a plant-based bio resin that delivers strong, resilient bonding while supporting more sustainable manufacturing practices. This innovative resin contributes to the ski’s overall durability and helps maintain peak performance throughout demanding seasons.
• RACE BASE – The high-efficiency RACE BASE is engineered to promote earlier line engagement and easier, more controlled turns. This low-friction base material helps you build speed more naturally and maintain momentum across the course, supporting consistent performance even on tight line lengths.
• ENDURO TIP/TAIL – Designed for balanced speed and precise control, the ENDUR0 Tip and Tail construction creates a stable, predictable feel when moving aggressively from edge to edge. This design supports confident tracking into each buoy and consistent exits without compromising smoothness or balance.
• RADAR LAB MADE – Every Radar Lithium Vapor is handcrafted in the Radar Lab, where meticulous attention to detail and a commitment to innovation guide each stage of production. Thanks to Herb O’Brien’s legacy, this ski reflects decades of research, testing, and refinement that have shaped it into a trusted tool for passionate skiers worldwide.

Optional Binding: Radar Vector Boa

For enhanced comfort and control, the Lithium Vapor pairs perfectly with the Vector Boa bindings, which offer secure fit customization and responsive support to match the ski’s high-performance character.

• Boa Closure System – The Vector Boa bindings feature a micro-adjustable Boa dial, making it simple to achieve a precise, even fit that adapts to your foot. This closure system distributes pressure evenly, allowing you to customize tension quickly while reducing hot spots and discomfort during long sessions.
• Feather Frame Chassis – The lightweight Feather Frame Chassis offers a low-profile connection to the ski that enhances responsiveness while maintaining ergonomic support. This design absorbs impacts effectively and provides stable footing that helps reduce fatigue as you navigate challenging courses.
• Reactive Wrap Construction – The multi-layered Reactive Wrap adapts naturally to the contours of your foot, creating reliable heel hold and lateral support. This flexible construction helps you maintain balance and control through aggressive turns without restricting natural movement or comfort.

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.
