The USS Calumet (SP-723) was a United States Navy patrol vessel in commission from 1917 to 1919, originally constructed as a private steam yacht. Built in 1903 by George Lawley & Son in Neponset, Massachusetts, the vessel was designed for private use before being acquired by the Navy during World War I. On September 9, 1917, the U.S. Navy took possession of Calumet under a free lease from her owner, repurposing her as a section patrol boat. She was officially commissioned as USS Calumet (SP-723) on December 7, 1917. The vessel’s specifications are not detailed on the provided page, but her role was primarily as a guard ship and harbor entrance patrol craft within the 3rd Naval District, centered around New York City. During her service, Calumet played a critical role in maritime security, patrolling the harbor entrance to safeguard against enemy submarines and other threats. She also provided local antisubmarine escort duties, assisting in the protection of inshore convoys traveling along the U.S. East Coast, particularly in the vicinity of New York Harbor. After the conclusion of World War I, USS Calumet was decommissioned in New York City on January 11, 1919, and was returned to her owner. Following her naval service, she continued to serve as a private yacht until she was scrapped in 1929. Her service exemplifies the common practice during wartime of converting private vessels for military use, contributing to the maritime defense efforts along the U.S. coast during a period of heightened security concerns.
