The Design 1013 ship (full name Emergency Fleet Corporation Design 1013), also known as the Robert Dollar type, was a steel-hulled cargo ship design approved for mass production by the United States Shipping Board's Emergency Fleet Corporation (EFT) in World War I. Like many of the early designs approved by the EFT, the Design 1013 did not originate with the EFT itself but was based on an existing cargo ship design, in this case one developed by the Skinner & Eddy Corporation of Seattle, Washington.
The Design 1013 ships had a deadweight tonnage of 8,800 and gross register tonnage of 5,600. They had a length of 423 feet 9 inches, beam of 54 feet, draft of 24 feet 2 inches and hold depth of 29 feet 9 inches. Some were powered by Curtis geared steam turbines and others by vertical triple expansion reciprocating steam engines, in either case yielding a service speed of between 11 and 12 knots. Some of the vessels were oil-fired and others coal-fired. They were produced by a variety of shipyards on the west coast of the U.S. including Skinner & Eddy and J. F. Duthie & Co. of Seattle, Los Angeles Shipbuilding & Drydock of Los Angeles, California, and the Northwest Steel Company and Columbia River Shipbuilding Company of Portland, Oregon. Most of them were given names starting with the word West (or in some cases, Western), indicating their west coast origins.
