Description
The Hiram Robinson was a wooden screw-propelled tugboat constructed in 1910. Fabricated by the Collingwood Shipbuilding Co. in Collingwood, Ontario, the vessel was assembled in Pembroke, Ontario.

The tugboat was powered by a 15-30×24 engine, also manufactured by Collingwood Shipbuilding Co.
History
Commissioned by the Upper Ottawa Improvement Co., the Hiram Robinson served primarily in the Ottawa River region. Her duties likely included towing logs and assisting in river navigation, supporting the lumber industry that was prominent in the area during the early 20th century. The vessel’s robust construction and reliable performance made her a valuable asset for operations along the Upper Ottawa River.
Significant Incidents
There are no records indicating that the remains of the Hiram Robinson were discovered or documented after her scuttling.
Final Disposition
In 1956, after decades of service, the Hiram Robinson was scuttled, and her hull was repurposed as a pier. This practice was common during the period, as decommissioned vessels were often utilized to create breakwaters or piers, contributing to infrastructure development along waterways.
