The USCGC Cactus (WLB-270) was a 180-foot (55-meter) seagoing buoy tender of the Cactus-class, constructed by Marine Ironworks and Shipbuilding Corporation in Duluth, Minnesota. The vessel's preliminary design was developed by the United States Lighthouse Service, with the final design produced by Marine Iron and Shipbuilding. The keel was laid on March 31, 1941, and she was launched on November 25, 1941. Commissioned on September 1, 1942, the Cactus was built at a cost of approximately $782,381 for hull and machinery. As one of 39 original 180-foot buoy tenders built during World War II, Cactus primarily served in the First Coast Guard District, stationed in Boston, Massachusetts. Her early service included tending aids to navigation, search and rescue operations, icebreaking, and law enforcement duties. Throughout her operational history, she participated in numerous notable events, including a collision with MV Manasquan in June 1943, which caused significant damage. She also provided assistance to various fishing vessels and merchant ships, such as FV Dorothy, FV Mary, FV Jane, FV Patricia, Western Pride, and Franco Lisi, and fought fires on piers and vessels in Boston. In the early 1960s, Cactus was reclassified as an oceanographic buoy tender (WLBO-270) and was one of two such vessels in Boston, painted white to denote her new role. She continued her service into the late 1960s, assisting disabled ships like MS South African Victory and FV Chrisway. Her homeport shifted from Boston to Bristol, Rhode Island, in 1967, and then to Tongue Point in Astoria, Oregon, in December 1969. Her service ended after a severe incident in 1971 when she ran aground on the South Jetty at Grays Harbor, Washington. The vessel was heavily damaged, with ruptured cargo holds, a holed engine room, and inoperative engines. She was successfully re-floated and towed to Seattle but was decommissioned afterward. Subsequently sold into private hands, she was converted into a barge but remained abandoned and deteriorating in the Pacific Northwest, notably at Maury Island, until her final disposal. Her extensive operational history highlights her importance in navigation, rescue, and law enforcement along the U.S. coasts during her active years.
