ABSTRACT:
A composite barge-tug vessel is provided which comprises a detachable tug and barge which when brought into full engagement form an integrated vessel capable of use on the high seas. The barge includes, at the aft end thereof, a pair of spaced rearwardly extending stern fins the upper surfaces of which form inclined mating or aligning planes. The tug includes laterally extending wings whose undersurfaces form aligning planes that mate with the aligning planes of the barge, the sliding engagement between the pair of aligning planes enabling the wings of the tug to be driven up onto the stern fins of the barge. A prow tongue on the tug engages in a slot formed between the stern fins and projections at the tip ends of the stern fins engage in connection apertures formed at the sides of the tug. Wedging surfaces at the connections between the tug and barge prevent lateral movement while a wedging assembly located at the aligning planes fixes the longitudinal positions of the tug and barge.
