Year of Build: 1892
Official Number: 100037

Construction and Ownership

The Mabel Macdonald was a small screw-propelled tugboat built in 1892 in Toronto, Ontario. Measuring 54 feet in length, 12 feet in beam, and 8 feet in depth, the tug had a gross tonnage of 42 tons. Over its operational life, the Mabel Macdonald changed ownership several times, reflecting its steady but varied service in towing and other maritime operations.

Engine:
The vessel was powered by an engine (16×20) built by Knight & Son, a notable engine manufacturer of the time. This engine made the Mabel Macdonald an efficient tug, suitable for its role in helping to maneuver other vessels in and out of tight waterways, ports, and harbors.

Chronology of Ownership and Usage

• 1895-1901: The Mabel Macdonald was owned by A. Manning et al. in Toronto, serving as a working tugboat in the busy port of Toronto, which was an important hub for commercial and industrial maritime traffic.
• 1917: Ownership transferred to the Randolph Macdonald Co., also based in Toronto, marking a continued role in towing and harbor operations.
• 1921: The vessel was sold to Dickson & McGragh, another Toronto-based company. Tugboats like the Mabel Macdonald were vital assets in the rapidly growing industrial port cities, helping move barges, ships, and construction materials.
• 1928: Ownership changed to W. Hand of Port Dalhousie, a town on the shores of Lake Ontario. Port Dalhousie was a key location due to its proximity to the Welland Canal, connecting Lake Ontario to Lake Erie, where tugboats were frequently used to assist larger vessels.
• 1931-1935: The Mabel Macdonald was renamed R.C. Co. No.3 after it was acquired by the Russell Construction Co. in Toronto in 1935. By this time, it had likely been repurposed for use in various construction projects on the waterfront or aiding in marine construction activities.

Final Disposition

The Mabel Macdonald met its end when it was scuttled on December 29, 1944 in Lake Ontario. Scuttling was a common method of disposal for old or decommissioned ships, particularly those that had outlived their usefulness. Sinking a vessel could serve multiple purposes: it removed the vessel from service, cleared space in harbors, and, in some cases, even created artificial reefs or underwater obstructions.

Tugboats like the Mabel Macdonald played a key role in facilitating the movement of cargo ships, barges, and other large vessels in busy and often cramped port environments. Over its five decades of service, the Mabel Macdonald changed hands several times, showing its versatility and enduring value.

The scuttling of the vessel in 1944 marked the end of its long operational life.
