We Say: Supra's new 21-foot, 14-seater SR 450 is ready to take on big lakes with a big crew, whether they are skiers, wakeboarders or wakesurfers. Toward that end, the SR 450 is equipped with a host of systems to help you personalize the watersports experience. The list includes 3,000 pounds of ballast capacity, Zero Off GPS Speed Control, Supra Launch System 2.0, Swell System 2.0, Smart Plate 2.0, and the new, inclinometer-driven Auto Wake. You harness all this wake-shaping via the intuitive helm interface that Supra calls Vision Touch System. We found Vision Touch System slick and easy to use. It controls other systems, such as the killer stereo and JL speakers, and displays functions as diverse as fuel, engine diagnostics and rider profiles.
