Radar T.R.A. Vapor Kid's Waterski 2025

The Radar T.R.A. Vapor Kid’s Waterski 2025 is the ultimate high-performance waterski for junior athletes ready to chase buoys and elevate their slalom game. Built from the same design lineage as Radar’s world-renowned Pro Build Vapor, this ski delivers race-ready performance in a youth-specific package. From the lighter PVC core to the refined carbon layup, every element of the T.R.A. is engineered to maximize edge control, responsiveness, and speed for lighter skiers. Whether your grom is carving up the course or free skiing with style, this ski empowers young riders to push limits and develop the technique, confidence, and control of tomorrow’s champions.

Key Features:

PVC Core – Tested and proven response. This lightweight, high-rebound core provides exceptional energy return and torsional stability, allowing junior skiers to initiate turns quickly while maintaining full control throughout the arc. The reduced swing weight helps younger athletes maintain balance and form without unnecessary resistance.
Sigmatex Carbon – Consistent flex every time. Constructed with advanced Sigmatex carbon fiber, this ski ensures a reliable flex pattern that holds true under stress. The result is predictable performance set after set, with enhanced strength and vibration dampening for smooth, clean cuts.
Bio Resin – Plant based and better. An eco-friendly advancement in ski manufacturing, this bio-based resin system maintains durability and performance while reducing environmental impact. It’s a small change that makes a big difference in the sustainability of high-performance equipment.
True Feel Base – A better connection to the water. The specialized base material enhances ski-to-water feedback, giving young riders the ability to feel subtle variations in surface texture and water flow. This connection builds confidence and helps refine technique with every ride.
Enduro Tip/Tail – Built for speed. Engineered to withstand aggressive skiing and tight turns, the reinforced tip and tail offer durability and directional control. They allow the ski to stay planted and fast through the apex while transitioning quickly across the wakes.
Radar Lab Made – Thanks Herb. Handcrafted in the Radar Lab, this ski is a direct result of years of research, testing, and waterskiing innovation. Built to the highest standards of quality and precision, every T.R.A. model carries the legacy of world-class performance.
Terrain – Course. Optimized for slalom course skiing, the T.R.A. offers quick edge changes, powerful carving, and stable acceleration for tight-radius turns, making it the ideal training tool for aspiring competitors.
Recommended Speed Range – 26–36 MPH. Designed to perform at a range of speeds suited for junior development and competition-level riding, this ski adapts to each rider's comfort and performance zone without compromising handling or stability.
Recommended Weight Range – 63.5" (85–120 lbs) | 65" (110–145 lbs). Two finely tuned size options ensure the ski’s flex and performance match the skier’s weight, helping young athletes maintain control, form, and progression as they grow.
Surface Area – 63.5" (336.11 SQ") | 65" (344.05 SQ"). Optimized surface area delivers the perfect blend of lift, agility, and grip on the water, keeping the ski fast, stable, and highly maneuverable in all course conditions.
Max Width – 63.5" (6.749") | 65" (6.749"). The generous width provides added stability and turning leverage, enabling smoother initiation and exit during aggressive edge transitions, especially at high speeds.

If your junior skier is serious about performance, the 2025 Radar T.R.A. Vapor is the ski to get them there. Built with precision, tuned for youth performance, and inspired by pro-level innovation, it’s the ultimate weapon for the next generation of slalom stars.

Radar: Our latest Vapor is the culmination of all the skis we’ve created to date. Every time we build a new ski, we learn something; defining what bevel shape is best and which rocker line is most balanced is now rooted in our DNA. As we approached this ski we reflected upon things in our past and learned from what we’ve tried before. The result is a ski that finishes the turn with more angle and speed than its predecessor and sweeps away from the wake with ease. By sharpening the bevel in the front half of the ski we created a ski that’s more intuitive as it enters the turn; this combined with narrowing the tail of the ski creates sustainable angle that can be carried from the finish of the turn through centerline. The balance you feel over your feet is a direct re-sult of the rocker built into the shape of the ski. Our rocker line flattens fore and aft of the wide spot providing a larger platform. This places you over the front foot with ease, making tighter, more consistent turns. Fundamentally, the lower rocker line dramatically improves feedback from the ski and leads to a more natural and intuitive feeling ride. The way this ski flows from turn to turn with the speed only a Vapor is known for will have you running more buoys than ever before. Ski it for yourself.

Shape

The first thing we addressed on the shape of the ski was the width profile, while keeping the max width of the ski the same; we added more radius to the profile to provide more pivot and rotational pull through the turn. We also added width behind the wide point to keep the ski more level and stable in the turn. This provides the ski with built in tip pressure and reduces the need to “climb” over the ski to make a turn. The ski is now able to move under the line at a quicker rate with a more natural feel. By reducing volume in the tail of the ski we were able to create more leverage that enables the whole ski to move better as a single unit through the turn. This results in attainable angle that can be carried all the way through the finish of the turn. The last adjust-ment in shape was the narrowing of the tip. This combined with our rocker line enables more bevel contact resulting in a secure feeling that lets you stand over the ski with confidence to rip turns knowing that the ski will move with you from apex to center line.

Rocker

By increasing the taper of the rocker line fore and aft of the flat spot we en-larged the sweet spot of the ski even more. The flatter the rocker is under-neath your feet the more improved feel and connection you have with your ski. This allows you to move yourself and the ski better as a single unit. A big-ger platform also gives you the ability to be more reactive and dynamic with your movements, ultimately giving you the control to move in and out of the turn with power. The lower rocker in the front half of the ski gives a truly unique feeling. By being flatter to the water you’re able to move over the ski with more confidence knowing that there is more contact, and support built into the ski. As you move over your feet the bevel is engaged and tighter, more consistent turns bring you back under the rope and cross course to the next buoy.

Concave

We have been extremely happy with the concave we created in the previous shape. The deeper concave with a steeper entry gives the speed and side to side drive a Vapor is known for having. Speed is only good if you can control it, and this concave also provides grip that allows the ski to naturally slow down as it enters the turn. This ultimately enables the ski to carry a more constant speed through the turn which improves your cadence and rhythm with the boat.

Bevel

Sharpening the bevel from your feet forward has given the Vapor more grip and control than any ski we’ve created to date. This helps the ski decelerate so it can make tighter, more up course turns. It’s important to note that these tighter turns are attainable due to the bevel transition built into the tail of the ski. By softening this bevel behind your feet, the ski can stay more balanced so that angle and drive are able to be maintained from the apex of the turn through centerline.

Thickness

Sidewall height carries constant to provide balance. To keep the ski nimble the sidewall thickness is reduced which also produces the connected, tight turning radius of the ski.

Edge Angle

The Vapor width allows the ski to achieve maximum edge angle both in the turn and while cutting. This width sets the precedent in our line as the pinnacle of performance both in the course and while free skiing.
