Product description
Men's Slalom Waterski — Radar — 2026
Who this is for
Intermediate to advanced skiers who want a proper performance ski at slower boat speeds — 28 to 30 MPH. The Union is built for real-world Okanagan conditions: afternoon chop, mixed-up water, early-season rust, and busy lakes where you’re not always skiing on glass.
Shop Owner’s Take
“I personally ski the Union to start my season. I have a Graphite Senate in the locker, but I only bring that out when the water is perfect and I’ve got my ski legs under me. The Union is just easier. It handles the Okanagan late morning chop with ease and makes getting back up to speed at the start of the year actually fun, and easy.”
Attridge Recommended Speed: 28–30 MPH
The ski
The 2026 Radar Union is the sanity ski for the North Okanagan. Radar takes the record-breaking Vapor DNA and adds 0.4” of extra width outside the tunnel, which gives the Union significantly more surface area and lift — letting you stay on top of the water at 24–32 MPH without the physical strain of a narrow tournament ski. Crucially, the tunnel configuration is preserved so the ski still rolls aggressively onto edge when you want it to. The High-Speed Flow Line uses straight outline edges from the wide point through the tail, reducing drag and making the Union fast and smooth across the wakes despite the slower boat speed. The 2026 version carries a decreased rocker under the front foot feeding into a continuous rocker through the rest of the ski — more predictable handling, increased angle through turns, and speed generated earlier out of the turn. Deeper concave throughout adds tail lift and turn support, reducing blowouts. The All-Terrain Core is a machined aero core with Paulownia wood stringers and 100% carbon laminating — fast, stable, and damped enough to absorb the afternoon chop on Kalamalka Lake without beating you up. As we break down in our How to Choose Your Radar Slalom Waterski in 2026 guide, the Union is the ski you grab when the lake is busy, the wind is up, or you just want a low-stress session that feels like a win every time.
What makes it work
All-Terrain Core
Radar’s most forgiving construction — a machined aero core with Paulownia wood stringers and 100% carbon laminating. It’s engineered to dampen and absorb vibration rather than transmit it, which is the difference between a pleasant afternoon session in Okanagan chop and a session that beats you up. Forgiving without being slow.
Vapor DNA + Extra Width
The Union is built on the same shape as the Vapor — Radar’s pro-level course ski — with 0.4” of additional width added outside the tunnel. The tunnel itself is unchanged, so edge hold and concave performance carry over. The extra surface area provides lift and buoyancy at slower speeds without sacrificing the ski’s ability to bite hard when you lean into it.
High-Speed Flow Line
Straight outline edges from the wide point through the tail reduce drag and increase water flow efficiency. The result is a ski that feels fast and smooth crossing the wakes at 28 MPH — not sluggish or sticky. The Union slows the boat down without slowing you down.
2026 Rocker & Concave Updates
Decreased rocker under the front foot flows into a continuous rocker through the rest of the ski — more predictable feel, more angle through turns, and earlier speed generation out of the turn. Deeper concave throughout adds tail lift and support in the turn, reducing tail blowouts when you push hard on Okanagan Lake.

Sizing is based on average fitness and ability. Stronger or more advanced skiers often size down; beginners or those returning to the sport may prefer to size up for more stability. Not sure which size fits your build and speed? Read our How to Choose Your Radar Slalom Waterski in 2026 guide or call us — water ski sizing is one of the things we know well.
Attridge recommended speed: 28–30 MPH — Radar’s published range of 24–32 MPH covers a very broad spectrum. In our experience on North Okanagan lakes, 28–30 MPH is where the Union feels best for most recreational skiers. If you’re running the course or pushing harder, dial it up from there.
