ABSTRACT:
An integrated and separable tug and barge unit of the Catamaran type is provided which constitutes a material improvement in operational efficiency and economy over the separable tug and barge assembly forming the basis of U.S. Pat. No. 3,698,349 granted on Oct. 17, 1972 to John N. Stevens. The tug and barge assembly of the present invention is characterized by providing a materially improved hull design for the twin hulls of the tug unit, both fore and aft, and material design changes with respect to the interfitting of the tug unit with the barge unit which will materially decrease the open area between the twin hulls of the tug unit when the units are in an interfitted relationship.
