HMCS Baffin was an Isles-class anti-submarine trawler originally constructed for the Royal Navy during World War II. Built at Collingwood Shipbuilding in Ontario, the vessel's keel was laid on October 14, 1941, and she was launched on April 13, 1942. The ship was completed by August 20, 1942. Although constructed in Canada, Baffin was loaned to the Royal Canadian Navy, where she was crewed by Royal Navy personnel and served primarily out of Halifax, Nova Scotia, performing anti-submarine and minesweeping duties. The Isles-class ships, including Baffin, displaced approximately 545 long tons (554 tonnes) at standard load and up to 770 long tons (780 tonnes) at deep load. They measured 164 feet (50 meters) in length overall, with a beam of 27 feet 8 inches (8.43 meters) and a draught of 11 feet 1 inch (3.38 meters). Propelled by a single shaft driven by a vertical triple-expansion steam engine powered by a single boiler, Baffin could reach a maximum speed of around 12.25 knots (22.69 km/h). Her armament included a single QF 12-pounder 12 cwt gun and three Oerlikon 20 mm cannons for anti-aircraft defense. The vessel's complement ranged from 35 to 40 officers and ratings. During her service in World War II, Baffin was engaged mainly in minesweeping and anti-submarine operations from Halifax. Following the war, she was returned to the Royal Navy on August 20, 1945. Subsequently, she was sold into mercantile service and underwent several transformations. In 1947, she was converted into a 453 GRT trawler registered to Harbour Specialties Ltd. In 1952, she was sold to F. Osterwisch & Co KG, fitted with a new diesel engine, and renamed Niedermehnen, becoming a cargo vessel with a 494 GRT tonnage. Her subsequent names included Kellenhusen, Kairos, and Theoxenia, reflecting her changing ownership over the years. The vessel was ultimately broken up in 1983 and removed from Lloyd's Register in 1995, marking the end of her maritime career.
