Radar Senate Lithium Waterski
The Radar Senate Lithium is the most versatile ski in the Radar lineup, designed to perform across a wide range of skiers, speeds and conditions. Blending efficient energy transfer with forgiving control, the Senate Lithium is equally capable of running deep shortline passes or cruising comfortably in open water.
Constructed with a PVC core and spread tow carbon, the Lithium delivers a responsive yet approachable feel that suits both progressing and experienced skiers. This balanced construction allows the ski to remain lively and fast when pushed while staying predictable and easy to manage during longer sets or relaxed sessions.
The Senate series builds on the Vapor shape by adding subtle width between the tunnel and edge bevel, rather than simply scaling the ski larger. This preserves the Vapor’s active wet surface, ensuring the Senate turns, rolls and grips with the same confidence while providing added support at slightly slower speeds.
Fast where it needs to be and composed through the turn, the Senate Lithium offers an ideal blend of performance and accessibility. From seasoned skiers returning to form to 34 mph competitors chasing new line lengths, this ski consistently delivers confidence, speed and control.
Feature Function Spotlight:
Performance Width is central to the Senate Lithium’s versatility. By adding surface area through a subtle rail between the concave and bevel, the ski gains lift and support without compromising roll speed or grip. This allows skiers to slow the boat while maintaining the ability to attack the water with confidence and precision.
