The SS Princess Kathleen was a notable passenger and freight steamship operated by Canadian Pacific Steamships, primarily serving the coastal regions of British Columbia, Alaska, and Washington. Built by John Brown & Company in Clydebank and launched in 1924, the vessel was designed to replace earlier ships requisitioned during World War I, specifically the Princess Irene and Princess Margaret. Her maiden voyage commenced in 1925, traveling from Glasgow to Vancouver via the Panama Canal. Constructed to accommodate a substantial number of passengers, the Princess Kathleen initially had a capacity of 1,500 passengers, with 290 berths and 136 staterooms, complemented by a 168-seat dining room and the ability to carry 30 automobiles. To enhance passenger capacity, she was later modified to hold 1,800 passengers by reducing the number of staterooms to 123. The ship quickly gained popularity on the Vancouver-Victoria-Seattle route, replacing older vessels like the Princess Charlotte and Princess Victoria, and competing successfully against rivals such as the Black Ball Line. A distinguished moment in her service history occurred in 1939 when King George VI and Queen Elizabeth traveled aboard her en route to Victoria. During World War II, the Princess Kathleen and her sister ship were requisitioned by the Royal Canadian Navy for use as troop transports. While Princess Marguerite was lost in action, Princess Kathleen was returned to civilian service in 1947 and resumed her route operations. In 1949, she was transferred to the Vancouver–Alaska cruise route along the Inside Passage, reflecting her versatility. Her maritime career ended on September 7, 1952, when she ran aground at Lena Point in Alaska’s Lynn Canal during low tide, with radar non-operational at the time. Efforts to free her failed as the rising tide caused her stern to become swamped, leading to her sinking stern first. The wreck now lies at a depth of 50–100 feet, accessible to divers, though challenging due to strong tides and currents. A salvage operation in 2010 removed 130,000 gallons of petroleum from the site, highlighting ongoing environmental concerns related to the wreck.
