ABSTRACT:
Tug/barge apparatus comprises a barge with a notch in the stern shaped to receive the bow of a tug, and the barge being coupled to the tug by a rigid coupling member on the barge which is adapted to be releasably retained in a bearing socket member formed in the bow of the tug. The coupling member is made buoyant enough to float on the water and the bearing member is located in the vicinity of the water line at the bow of the tug so that the two are at essentially the same level when the tug moves into the notch in the stern of the barge to effect a coupling operation. The coupling and bearing members are releasably retained in coupled relation and prevented from inadvertent uncoupling thereof.
