William King, 1841, & Bruce, 1875

William King, 1841 Originally known as the William Annesley, it was built in 1824 by H. Logan of Montreal, Quebec. It was renamed to the William King in 1828.

It was reported in the Montreal Herald that "[w]e are informed that a beautiful little steamboat is now building…. upon the exact model of a canoe…It is perhaps the smallest ever constructed. It is intended to ply foot passengers across the river between the usual passage roads to Laprairie and Longueuil."

The William Annesley (later King) was designed by William Annesley in pursuit of testing a new patent system that "involved no ribs and alternate layers of thin boards with oiled paper between" (Maritime History of the Great Lakes)

It was rebuilt several times, with the paddle wheels and engine removed in 1827 to allow it to serve on the Rideau Canal from 1827-1829 and later the Lachine Canal in 1830. An "additional shade deck" was added in 1829.

Its engine was later reused in the Bytown (built 1834). The William King was soon abandoned in the Ottawa area and sank. Around 1980, it was moved to the Ottawa Rowing Club to serve as a dive area known as 'Morrison's Quarry.'

Bruce, 1875 Originally named the Islander, it was built in 1846 by D. Dibble of Kelly's Island, Ohio, USA. It was 100 feet long, and 17 feet wide. The Islander was renamed to the Bruce in 1862, which is when it started serving in Canadian waters after its purchase by Van Every & Rumball of Goderick, ON. Detlor & Son bought it in 1866, D. S. Booth of Brockville in 1868, Schofield & Rochester of Ottawa in 1873, and Mr. Bourgeau of Alymer in 1874. During one of the sales it was renamed to the Seaman, but was mostly known as the Bruce for the time that it was in Canada.

It sank in 1874 in Ottawa due to being overloaded, but was raised in early July. It caught fire in 1875 near Hull, Quebec, and sank below the waters. The hull was raised in 1982 and relocated under the Ottawa Rowing Club wharf as part of 'Morrison's Quarry' by the Santa Maria Society.
