The Bonnington was a notable sternwheel steamboat that operated on the Arrow Lakes in British Columbia from 1911 to 1931. Recognized as one of the largest sternwheelers ever built in British Columbia, alongside her sister ships Nasookin and Sicamous, she represented the peak of inland steamboat design and luxury during the early 20th century. Constructed with a steel hull manufactured by Polson Iron Works of Toronto, the Bonnington's hull was assembled at the Bulger shipyard in Nakusp, composed of 20 watertight compartments with a remarkably shallow draft of only 3.5 feet, allowing navigation in shallow waters. Her hull was almost flat at the bottom to facilitate this. She featured four decks, a distinctive design departure from the typical three-deck pattern of most sternwheelers, including a "gallery" deck above the saloon and below the Texas deck, providing panoramic views and high ceilings in the dining room, which seated 60 guests. Powering the vessel were two of the largest compound steam engines ever installed on a Canadian sternwheeler, built by Polson Iron Works. The vessel's locomotive-type boiler was 9 feet in diameter and 28.3 feet long, with a grate area exceeding 70 square feet and a heating surface of 2,750 square feet, capable of consuming up to 3,800 pounds of coal per hour. The sternwheel had a diameter of 25 feet and featured 20 buckets, contributing to her distinctive paddlewheel propulsion. Designed for passenger luxury, Bonnington had 62 staterooms with electric lighting and steam heating, a large dining room, observation rooms, a smoking room, and various lounges, making her the epitome of elegance on inland waters. Despite her size and luxury, she was relatively slow and less maneuverable in crosswinds. She primarily served the route from Arrowhead to Robson West during the busy summer months, but her operation was hampered by low water levels in winter and declining traffic due to competition from railroads and roads. After her retirement in 1931 amid the economic downturn and declining tourism, Bonnington was laid up at Nakusp. She was later sold, partially dismantled, and used as a source of spare parts. Eventually, she sank in 1960 near Beaton, where her wreck remains the largest freshwater shipwreck site in British Columbia, lying in the Northeast Arm. Her preserved sister ship Sicamous remains as a museum, highlighting her significance in British Columbia's maritime history.
