Radar Pro Build Vapor Water Ski (Textreme/Stealth) 2025

The 2025 Radar Pro Build Vapor Water Ski is the ultimate expression of slalom course engineering, built for elite performance and precision at the highest levels of the sport. Designed to perform flawlessly at speeds between 32–36 MPH, this ski is the model of choice for Radar’s Pro Team and podium-seeking athletes around the world. But it’s not just for pros—any committed skier looking to elevate their game will find this ski offers the responsiveness, balance, and edge control needed to unlock their full potential. Every inch of the Pro Build Vapor is purpose-built for course domination, from its advanced construction materials to its aerodynamic profile.

Constructed in the Radar Lab using the finest materials available, this ski incorporates a high-response PMI core, Textreme carbon laminates, and zonally tuned carbon rods to fine-tune flex and energy return. Paired with Radar’s signature True Feel base and Enduro tip/tail technology, the Pro Build Vapor delivers instantaneous edge changes, fluid arcs, and effortless acceleration across the wakes. The shape—refined through years of elite competition and R&D—offers a large sweet spot, intuitive turn initiation, and remarkable forgiveness for such a high-performance ski. Whether you’re chasing personal bests or competing at the national level, the Pro Build Vapor puts winning power in your hands.

Key Features:

• PMI Core – Lightweight, high density, most response. This aerospace-grade foam core is incredibly lightweight yet exceptionally strong, giving the ski unmatched rebound and acceleration while maintaining consistent flex. It enhances connection to the water and allows for quicker reaction time from edge to edge.
• Textreme Carbon – Lighter, stronger composites. Textreme woven carbon provides high tensile strength with minimal weight, resulting in a more reactive ski that remains stable under extreme pressure. It delivers explosive performance and laser-sharp control, ideal for high-speed course skiing.
• Carbon Rods – Zonal flex for the optimum layup. Strategically placed carbon rods control longitudinal and torsional flex zones within the ski. This tuning ensures that every part of the ski responds precisely when and where it's needed, creating seamless turns and efficient energy transfer.
• Bio Resin – Plant based and better. An environmentally friendly alternative to traditional resins, Radar’s bio resin maintains the integrity of the ski while reducing environmental impact. It also offers improved bonding characteristics for long-term durability.
• True Feel Base – A better connection to the water. Engineered for maximum feedback, this base material transmits more of the water’s texture to the skier, increasing awareness and control. It lets you stay in sync with every ripple and delivers enhanced confidence in your edge work.
• Enduro Tip/Tail – Built for speed. Reinforced tips and tails provide strength and durability during aggressive carves, helping maintain structural integrity and edge bite through the entire arc. It’s a high-speed design feature that ensures your ski tracks consistently and accelerates cleanly.
• Radar Lab Made – Thanks Herb. Handcrafted at the legendary Radar Lab with the oversight of Radar’s top engineers and athletes, every Pro Build Vapor is the result of relentless testing, innovation, and commitment to excellence. It’s the purest performance

  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.
