Radar's most popular ski, the Radar Alloy Senate utilizes a polyurethane core with Paulownia wood stringers wrapped in carbon fiber. This beauty of a ski is stable but fast and an absolute blast to ride whether you're ripping open water turns or getting into some course action. Ski the Alloy Senate from 26-34 MPH and enjoy the ride. The Radar Senate's ability to carry speed is unmatched in the industry. This speed allows the skier to maintain width on the boat ultimately giving a sense of freedom sought after by those that ski in the course as well as those ripping open water turns. By taking the Vapor shape and adding two tenths of an inch in extra width, Radar created a stable riding platform. This platform creates the balance needed for a skier to feel at home, while the profile of the ski allows the skier to feel the speed and angle sought after at any level.• Most forgiving construction with All-Terrain Core• 100% carbon fiber for consistent flex every timetable, th, td {border: 1px solid black; border-collapse: collapse;}th {text-align: left;}th {padding-left: 6px;}td {padding-left: 6px;} Size Surface Area Max Width Suggested Speed Terrain Rider Weight 65" 350.57 sq. in. 6.94" 26-34 mph Crossover up to 170 lbs. 67" 378.85 sq. in. 7.16" 26-34 mph Crossover 160-200 lbs. 69" 401.81 sq. in. 7.37" 26-34 mph Crossover 180-220 lbs. 71" 413.43 sq. in. 7.37" 26-34 mph Crossover 200+ lbs. | Radar Senate Alloy Slalom Waterski, Blank 71 | The House
