An island south of Cape Cod, Mass. The town, Nantucket, on this island was a great whaling center during the 19th century.
The second Nantucket, a wooden light ship built in 1907 for the Lighthouse Service, was transferred to the Navy by the Executive Order 1 1 April 1917 with the entire Lighthouse Service.
In the Navy during World War I, she continued her former peacetime routine warning shipping away from Nantucket Shoals and aided in guarding nearby waters against U-boats. After peace was restored, Nantucket was returned to the Commerce Department 1 July 1919.
