Need for construction Steam navigation on the inland lakes of British Columbia was dominated by the River and Lake Service of the
Canadian Pacific Railway. Since the early 1890s the River and Lake Service had maintained steamboat service on
Okanagan,
Arrow and
Kootenay lakes. By 1910, with the important exceptions of the composite-hulled
Moyie on Kootenay Lake and
Minto on the Arrow Lakes, the wooden-hulled steamers of the River and Lake Service were starting to wear out and would need replacement. This time however the hulls of the replacements would be made of steel, although the cabins would be built of wood. It was also planned to greatly increase the passenger capacity of the vessels. The goal was to develop the entire Kootenay and Arrow Lakes area into a major tourist destination, as the C.P.R. had done with
Banff Similar vessels built at same time Bonnington was a near twin of the steamers
Naskookin and
Sicamous built shortly afterwards on
Kootenay and
Okanagan lakes respectively. Unusually for a sternwheeler,
Bonnington was equipped with compound steam engines, which were manufactured by
Polson Iron Works of
Toronto,
Ontario. The vessel's steel hull was also manufactured by Polson Iron Works and was then shipped in pieces to
Nakusp where it was assembled at the Bulger shipyard and the upper works, built of wood, were constructed. The components of the hull were shipped out from Ontario in 19 freight cars. The hull itself was divided into 20 watertight compartments, and to allow as shallow a draft as possible, the bottom of the hull was almost perfectly flat. The compound steam engines were highly efficient and had been employed in many ships, but they had never been used before on a sternwheeler.
Bonnington's sternwheel was in diameter and had 20 buckets, which was the steamboat word for paddles. There were 62 staterooms on the steamer, all with electric light and steam heat. The dining room was long and seated 60 people. In addition to the ladies cabin and the smoking room,
Bonnington had two observation rooms on the gallery deck, one forward and one aft. There was another lounge and officers and passenger cabins on the Texas deck. Overall
Bonnington was regarded as a luxurious vessel and the apex of the steamboat era of travel in British Columbia. ==Arrow Lakes service==
