Comfort and storage abound aboard the SA, thanks in large part to the subfloor ballast that holds up to 3,500 pounds of water. While most other brands offer plug-and-play ballast as an add-on, Supra forgoes that option, with the claim that it isn’t needed. Truth be told, it isn’t—which means more room for boards, gear and all your friends. The cushy interior stays cool even under the hot sun, thanks to Chill Tech Vinyl; a flip-up back on the portside lounge, as well as the convertible rear bench, allow for numerous seating arrangements. We also loved the optional flip-up backrests on the engine-cover sun pad—great for relaxing when you’re beached or at anchor. Of course, the premium JL Audio system only ups the entertainment factor, whether you’re in the boat or riding behind it.
