U. S. Navy Motor Tug No. 90 (classified YT-90 in 1920), 1919-1944.
Later Motor Tug No. 5 (YMT-5)

Motor Tug No. 90, a 54-ton, 65-foot wooden-hulled craft originally propelled by a four-cylinder gasoline engine, was built at the Pearl Harbor Naval Station, Hawaii, and entered service on 15 January 1919. The tug served her entire career at Pearl Harbor. She was classified YT-90 when the Navy implemented its standard hull classification system in July 1920 and, in 1929 when the motor tugs were given their own hull symbol, was renamed Motor Tug No. 5 and reclassified YMT-5. During the early part of World War II her 150 horsepower gasoline engine was replaced with a 240 horsepower diesel. In March 1944 a survey board recommended that her machinery and fittings be removed and hull condemned, and she was placed out of service. In May 1944 she was stricken from the Naval Vessel Register and scrapped.
