Checkered flag graphics wrap a 70 by 51 inch deck with two molded cockpits, so a pair of riders sits down inside the hull with the sidewalls at chest level. The 340-pound rating covers one or two riders over 14 years old, and the 14 by 15 inch seats keep both bodies low as the boat turns. Inside sits a heavy-duty PVC bladder, sheathed in 840D and 420D nylon covers with double stitching at the stress points and reinforcement where the foam padded handles attach. A quick connector at the nose takes a tow rope rated to at least 2380 pounds, with 50 to 65 feet recommended behind the boat, and bottom drainage clears standing water so the tube planes instead of dragging. Working pressure is 1 psi. Keep speeds under 20 mph, wind below 3 Beaufort and waves under 1 foot.
