The USCGC Raritan (WYT-93/WYTM-93) was a 110-foot (34-meter) harbor tug built specifically for the United States Coast Guard by Defoe Boat Works in Bay City, Michigan. Launched on March 23, 1939, alongside her sister vessel Naugatuck, Raritan represented the first dual launch in Bay City. She was part of the Arundel-type class, designed based on the successful 1934 Calumet-type 110-foot tugs, and was equipped with icebreaking capabilities, allowing her to break through ice up to 3 feet (0.91 meters) thick, making her well-suited for operations in icy waters. Commissioned on April 11, 1939, Raritan was initially assigned to harbor duties in Boston, Massachusetts. Her design and capabilities enabled her to serve in challenging ice conditions, which proved vital during her later service. During World War II, Raritan played a key role in the Greenland Patrol, which was established after Germany invaded Denmark and claimed Greenland. Along with other cutters, she was tasked with enforcing U.S. sovereignty, protecting cryolite mines at Ivittuut, and preventing German influence in Greenland. Her involvement in the Greenland Patrol began in August 1940, when she was among the first cutters assigned to this mission, alongside vessels like Duane, Modoc, and Northland. On November 1, 1941, Raritan was transferred from the Coast Guard to U.S. Navy control by Executive Order 8929, although she continued to operate out of Boston under Coast Guard personnel. After the war, she was returned to the Treasury Department on January 1, 1946, and remained in Boston before being transferred to Portsmouth, Virginia. In 1962, her home port was moved to Grand Haven, Michigan, where she served on the Great Lakes. Raritan was decommissioned on May 14, 1988, concluding her nearly five decades of service. Her long operational history highlights her importance as a versatile icebreaking harbor tug capable of supporting U.S. maritime and wartime missions.
