Banana-shaped hulls seat riders in a line: at 118 inches long and 37.5 inches wide, three passengers straddle the tube and lean together through a turn. Three 20-inch seat sections with anti-slip textured EVA hold passengers in place across sharp waves, and total bearing capacity reaches 462 pounds for adults and children over 14 years old. Mesh-reinforced PVC is thickened against punctures, and three separate air chambers with individual valves mean one leak does not end the day. Bumper strips run along both sides and the underside where the tube contacts the boat and the trailer. A 500-watt electric pump inflates the whole hull in two to three minutes, and each chamber tops out at 2.18 psi. The tow rope should carry at least 1500 pounds of tensile strength. Packed weight is 22 pounds with a 24 by 10.5 by 16 inch bag.
