The most important thing to remember when towing anyone behind the boat, whether on skis, a wakeboard, or on a tube, is to keep a safe distance from both fixed objects like docks, channel markers, bulkheads, or shorelines — and from shallow water on BOTH sides of the boat. While ropes made for towing tubers are sometimes shorter, a full-length ski rope measures 75 feet long — add another few feet to account for any yoke, or tow bridle, plus the length of the tube itself, and it’s best to consider 100 feet as a bare minimum safe distance. A tumbling tuber ejected from his or her ride will often travel an impressive distance above or on top of the water, so more room is safer. If you imagine a swath of water 300 feet wide (the length of a football field) with the boat at the center as your “safe zone,” then steer to prevent anything from entering that zone, you’ll be off to a good start. Keep in mind that tubers, more than skiers or wakeboarders, are at the mercy of the driver, because they can’t steer the tube, or release the line. here
