Radar TRA Junior Waterski 63in With Prime SM and ARTP Binding

Progression is fun; to keep our up-and-coming rippers hooked on the sport, we wanted to make a kids’ ski that was as balanced and predictable as it was fast and flowing. From the Senate shape with its performance-width design, the TRA is our easiest turning, most intuitive version to date. Big turns and buoys, high-fives and hugs, the TRA will have everyone in the boat feeling the slalom stoke.

Performance Width

Where we add surface area to the T.R.A. series is the backbone to bridging ease of use, with flat-out performance (think Senate design philosophy.) As opposed to simply scaling a Vapor wider we start with its active wet surface (the tunnel and edge bevels) and leave them relatively intact. From there we build surface area by adding a one tenth of an inch rail between the outer edge of the concave and the bevel. This small rail creates lift and support at slower speeds without sacrificing the ski’s roll, grip and drive through the wakes. This allows you to slow the boat, without slowing your ability to attack the water. From there we use a lighter weight carbon fiber that is better suited to the weight and strength of junior rippers.
