This is a BIG towable tube with a large, deep center crew cockpit for up to 2 riders and an outside deck radius for 3 riders. The cockpit is deep enough to stand in for the timid riders as there is a little chance of falling out. The outside of the boat tube is more adventurous. On the outside, the riders can stand, kneel, or lay down. Each position on the outside deck has a large anti-slip EVA pad for traction. Maximum capacity - 850 lbs. The floor of the towable tube for boating is a drop bottom which is what the tube mainly rides on. It allows the tube to ride smooth and fast over the wake and in the turns, and keeps the outside deck from digging in the water. This tube for boating comes with a 11 Inch 4K Aluminum EZ Tow Connector. It also has speed valves for faster inflation and deflation. This towable tube features full nylon cover with heavy-duty zippers, heavy-duty PVC bladder, double welding foam handles with knuckle guards and zipped, padded valve covers making this tube robust and long-lasting for years.
