The Princess Louise was a notable sidewheel steamboat constructed in 1869 in New York City by John English and Sons, originally named Olympia. Built for George S. Wright, the vessel measured approximately 180 feet in length with a beam of 30 feet and a depth of hold of 12.5 feet. Its hull was crafted from seasoned white oak, providing durability for its maritime operations. Power was supplied by a single-cylinder walking beam steam engine, manufactured by John Roach & Sons, with a 46-inch diameter cylinder and an 11-foot stroke, generating around 350 horsepower. The vessel had a gross tonnage of 971 and registered 493 tons as of 1874, and was equipped with an auxiliary brig rig for sailing. Olympia’s initial service began with a route between Olympia and Victoria in December 1869, replacing the slower Eliza Anderson. The vessel was involved in competitive racing and route disputes during the early 1870s, notably competing against the faster North Pacific, with a memorable race in June 1871 where North Pacific narrowly outpaced Olympia. Throughout the 1870s, the vessel operated primarily on Puget Sound, serving routes and participating in regional competitions. In 1878, the vessel was sold to the Hudson’s Bay Company (HBC), which renamed her Princess Louise in 1879, honoring Princess Louise, Duchess of Argyll. Under HBC ownership, she served various routes along the coast of British Columbia, including Vancouver Island and the mainland, and was involved in notable events like salvaging efforts after the wreck of the Otter in 1880 and transporting laborers during the construction of the Canadian Pacific Railway in 1881. Refitted in 1883 with new boilers, Princess Louise continued to serve until she was deemed in poor mechanical condition by 1901. The vessel was subsequently sold in 1906, converted into a barge, and sold multiple times, ultimately being beached and sinking by 1919. As the last commercial sidewheeler on British Columbia’s coast, Princess Louise holds maritime significance as a representative of the transition era in regional steamship transportation, reflecting technological, commercial, and regional developments over five decades.
