Radar Senate Alloy Waterski - Black / Forest

Radar Men’s Union Waterski

The Radar Men’s Union is designed for skiers who want high-energy performance at slower boat speeds without sacrificing the ability to roll aggressively onto edge. By blending a performance-oriented active wet surface with added stability outside the tunnel, the Union delivers a rare balance of easy starts, fast planing and powerful edge engagement.

Built for skiers slowing the boat down a few miles per hour, the Union starts with Radar’s proven Vapor shape and adds four tenths of an inch of additional surface area. Rather than widening the entire ski, this extra width is placed outside the concave, between the tunnel and the bevel. This preserves the tunnel configuration, allowing the ski to roll, grip and accelerate like a high-performance slalom ski, even at reduced speeds.

The result is a ski that is easy out of the water yet aggressive once on edge. Quick to find plane and confident through the turn, the Union remains lively and responsive while offering exceptional forgiveness in rougher water and crossover conditions. From relaxed open-water sessions to throwing walls in the course, the Union is built for pure enjoyment on the water.

Feature Function Spotlight:

High-Speed Flow Line geometry allows the Union to maintain speed and efficiency even when the boat slows down. Straight outline lines run from the ski’s wide point through the tail, reducing drag and increasing waterflow efficiency. The absence of an outside radius helps the ski move cleanly from wake to wake, delivering smooth acceleration and consistent edge hold without feeling stifled.
