Put the top down, grab your friends, and cruise down the lake in your own Convertible! This 3 person, fully covered tube is our most popular model on the lot. The Convertible is a 3 rider deck style tube built with a tapered front-to-back design tube that blends performance and classic design behind the boat. Riders lay flat on their stomach which provides a stable ride and a low center of gravity. Easily climb back aboard with one of the two handy rear-mounted boarding straps.
