Radar Senate Lithium Water Ski 2026

Radar Senate Lithium Water Ski

The Radar Senate Lithium Water Ski is the most versatile model in the Senate lineup, built for skiers who want high-end performance with the ability to adapt to different riding styles and conditions. Featuring a PVC foam core paired with Spread Tow Carbon, this ski delivers efficient energy transfer, giving riders quick acceleration and powerful response through the wakes while maintaining smooth, controlled handling.

The result is a ski that feels comfortable during relaxed open-water sessions yet still has the performance capability to handle aggressive turns and shorter line lengths in the course. If you’re unsure which ski in the Radar lineup best fits your style, the Senate Lithium is often the ideal choice thanks to its balanced mix of speed, control, and versatility.

At the core of its design is the renowned Senate shape, developed from Radar’s Vapor platform. By adding a small amount of width between the tunnel and the edge bevel, the ski maintains the same active wet surface as the Vapor. This allows it to retain the fast turning and precise grip of a high-performance slalom ski while providing additional lift and support at slightly slower speeds.

The Senate’s Performance Width concept further enhances usability by strategically adding surface area outside of the concave. This subtle rail between the concave and bevel increases lift without compromising edge-to-edge responsiveness, allowing the ski to roll, grip, and drive through the wakes with confidence while still supporting strong performance when the boat speed comes down.

• PVC Core - Lightweight foam core provides tested, responsive performance with efficient energy transfer.
• Spread Tow Carbon - Advanced carbon composite construction offers a lighter, stronger build with excellent response.
• Terrain – Crossover - Designed to perform comfortably in both the slalom course and open-water skiing.
• Recommended Speed Range – 28-34 MPH / 46-55 KPH - Tuned for strong performance across a wide range of advanced recreational speeds.
