Winifred was laid down as the first steel-hulled, single-screw cargo ship SS Winifred on 31 January 1898 at Bath, Maine by Bath Iron Works. Launched on 8 July 1898, she was delivered to her managing owners, Hiller, Bull, and Knowlton of New York City, on 1 October 1898. Winfred, the first steel tramp steamer designed and built in the United States, was built to operate for the New York and Porto Rico Steamship Company.[1]
Basic specifications as built are given as 304 feet 3 inches (92.7 m) length overall, 290 feet 0 inches (88.4 m) length L.W.L., 283.5 feet (86.4 m) registered length, 42 feet 0 inches (12.8 m) beam molded, 42.2 feet (12.9 m) registered beam, 25 feet 10.5 inches (7.9 m) depth molded center, 20 feet 0 inches (6.1 m) loaded draft with a gross tonnage of 2,456.48.[1][note 1] Watertight compartments were formed by six watertight bulkheads running up to the weather deck and two partial transverse bulkheads.
Propulsion machinery was a vertical triple expansion engine with cylinders of 20.5 inches (52.1 cm), 34 inches (86.4 cm) and 55 inches (139.7 cm) with stroke of 36 inches (91.4 cm) delivering about 1,100 horsepower at 100 revolutions turning a four-bladed propeller of 13 feet (4.0 m) for a normal cruising speed of over 10 knots.[1]
The ship had accommodations for up to eighteen passengers.[1]
The U.S. Navy acquired Winifred for World War I service on 21 June 1918 while she was in drydock at Liverpool, England. Assigned naval registry Identification Number (Id. No.) 1319, she was commissioned as USS Winifred the same day.
Assigned to the Naval Overseas Transportation Service and operating primarily from Cardiff, Winifred performed coastwise service in British waters and service across the English Channel, lifting supplies from English to French ports and vice versa, through the end of World War I.
Winifred was returned to the Gulf Refining Company. Once again SS Winifred, she operated from her home port of Port Arthur, Texas until 1936, when she was abandoned due to age and deterioration.
