The Bali is 10′ x 8′ and 6″ thick. The Bali’s dropstitch construction is so rigid and durable you wouldn’t know it’s inflatable unless you saw it being inflated. The secret to the Bali’s stability is the ballast bags which are located under the 4 corners of the Bali. Once submerged, these ballast bags fill up with water and work amazingly well to keep the Bali from shifting side to side and from tipping. The Bali comes with its own electric pump which makes inflation a breeze. Simply plug the electric pump into your cigarette lighter or use the alligator clips (included) to attach to your boat/car battery, turn the dial to the desired PSI and push start.
