A new concept in towing operations, known as the jet guidance unit, is a radio-controlled, diesel-powered small tug, being used in barge transportation. The new waterjet-powered unit is 36 ft long, 20 ft wide and 5 ft deep. Fitted at the rear of a tow pulled by a conventional lead tug, it enables the tow to be increased from two barges to three or four. As the unit is controlled remotely from the lead tug, control of the tow is far greater than with the conventional method of single-tug towing. The guidance unit functions as a steering, propulsion and braking mechanism. It enables the tug captain to have the tail end of the tow under control at all times and, in an emergency, to brake the tow and pulling tug. Upon arrival at a landing, the unit can be detached from the tow and operated manually to remove loaded barges from their moorings while the master tug holds the tow in midstream.
