The Fiji is 8' x 5' and 6" thick. The Fiji's drop stitch construction is so rigid and durable you wouldn't know it's inflatable unless you saw it being inflated. The secret to the Fiji's stability is the ballast bags, which are located under two opposite corners of the Fiji. Once submerged, these ballast bags fill up with water and work amazingly well to keep the Fiji from shifting side to side or tipping. The Fiji comes with its own electric pump that makes inflation a breeze. Simply plug the electric pump into your cigarette lighter or use the included alligator clips to attach to your boat/car battery, turn the dial to the desired PSI, and push start. The electric pump will fill the Fiji while you're getting the rest of your gear ready for your day on the water. Use it to lay out in the sun, let the kids play king of the hill, use it as a mobile dock or as a starting platform, attach the iShade tent (sold separately) to get some relief from the sun's rays, or simply set up a lawn chair and a cooler and cast your line in the water. The options are endless. The Fiji is made of the highest quality materials and is extremely durable. It's covered against any defects for a period of 1 year, but the Fiji will surely last for many years as long as it's properly cared for.
