The SEAWEDGE system of rigidly locking a tug into the stern recess of a barge is a development of the method first used in the Aztec Chief. Both tug and barge are of special design and, when coupled together, constitute a system with power/speed qualities similar to those of a conventional ship. Barges can thus be propelled at ship speed, or as required by the service. A detailed description of the system is followed by a discussion of its cost compared with those of a ship of similar deadweight, speed, and power. It is concluded that the system offers may advantages over traditional ship operation, which include versatility of operation, low running costs, and ship performance obtainable at low initial cost. The Aztec Chief and a sister unit Aztec King both made transatlantic voyages in 1975. The Aztec Chief is now being replaced by a new 2,800-bhp tug Chief II and a new barge.
