It served at the Chatham Coast Guard lifeboat station until 1968.","why_significant":"The nomination argues the boat is significant under Criterion A for its link to Chatham Coast Guard Station, lifesaving history and Cape Cod maritime history, especially the 1952 Pendleton rescue. Under Criterion C it represents the design and evolution of the 36-foot TRS motor lifeboat. An estimated 80-90% of its original fabric survives.","narrative":"Built in 1946 at the Coast Guard Yard in Curtis Bay, Maryland, CG 36500 is a 36-foot motor lifeboat of the TRS model, the standard rescue boat at most Coast Guard lifeboat stations for many years. It is double-ended, self-righting and self-bailing, with a 2,000-pound bronze ballast keel and a hull of white oak frames and cypress planking sheathed in Monel. It served at Chatham, Massachusetts, until 1968 and was later restored by the Orleans Historical Society, which displays it as a floating museum at Rock Harbor. Roughly 80 to 90 percent of its original fabric is estimated to survive. The boat is best known for the February 1952 rescue of 32 men from the broken tanker Pendleton during a northeaster, carried out across the Chatham bar with a crew of four, all of whom received the Gold Lifesaving Medal. It also illustrates the development of motor lifeboat design from the 18th century onward.","period_of_significance":"1946-1955","architect_builder":"Curtis Bay Maryland Coast Guard Yard","architectural_style":"Other-36 foot motor lifeboat","criteria":["A","C"],"status_note":"Owned and maintained by the Orleans Historical Society as a floating museum.
