She was built by the New York Shipbuilding Co. of Camden, New Jersey, for the U.S. Lighthouse Establishment.","why_significant":"The nomination argues she is one of the oldest surviving American lightships and the one with the greatest integrity, being the only surviving example to keep her original marine steam engine and machinery. She was among the first lightships on the Pacific coast and served the Blunts Reef, San Francisco and Seattle stations, supporting the nationally significant Pacific coast trade.","narrative":"Lightship No. 83, later known as San Francisco and finally Relief, is a steel-hulled vessel built in 1904 by the New York Shipbuilding Co. of Camden, New Jersey, for the U.S. Lighthouse Establishment. Originally stationed at Blunts Reef off northern California, she later served at San Francisco and Seattle, guiding ships to three major ports. She now floats as a museum vessel at Moss Bay Marina in Kirkland, Washington. She was built 112 feet long and enlarged in 1929 to about 130 feet. Her coal-fired boilers were converted to oil in the 1930s, yet she kept her original compound steam engine and auxiliary machinery. The vessel is regarded as one of the earliest surviving American lightships and the best preserved, since her engine, bell, pilothouse equipment and officers' quarters remain intact. Her lights and superstructure were updated in the early 1930s to suit her working purpose. The vessel has been unaltered since retirement in 1960 and is under gradual restoration.","period_of_significance":"1905-1960","architect_builder":"New York Shipbuilding Co.; U.S. Lighthouse Establishment","architectural_style":"Architecture (Naval)","criteria":[],"status_note":"Fair condition; moored as a museum vessel, undergoing slow preservation and restoration.
