AUTOMATIC BARGE CONTROL
The ABC (Automatic Barge Control) system described enables towed barges with ship-shaped forebodies to be used. A simple mechanism allows the pull in the towing hawser from the tug to be applied to the barge through a bridle, one end of which is connected to one of the two outboard ends of an athwartships beam pivoted on the barge centreline about one-sixth of the barge length aft. Each end of the beam is also connected rearwards to the control of a streamlined balanced rudder. The arrangement tends to automatically correct yawing of the towed barge and, together with the beneficial effects of the shaped forebody, results in a directional stability at least as good as that of a conventional ship and a much reduced towing resistance per ton of displacement. The towing arrangement is described in some detail.
