Wreck Location Map
Vessel Type
The P.W.D. 117, originally named Sir Wilfrid, is classified as a composite dredge barge, built primarily for dredging operations.
Description
Constructed in 1902 by Polson Iron Works in Toronto, the vessel was designed for dredging tasks and was notable for its composite construction. It was acquired by the Canadian Department of Public Works in 1909 and renamed P.W.D. 117.
History
On her maiden voyage in October 1902, the vessel suffered a significant incident when it broke its boom and sank off Port Hope in 65 feet of water. It was salvaged and rebuilt at Polson Iron Works before reentering service, primarily operating out of Port Stanley and often attended by the tug Hercules.
Significant Incidents
- October 1902: Maiden voyage incident leading to sinking and subsequent salvage.
- May 29, 1952: Sinking due to mechanical failure while dredging near the west breakwater at Port Stanley harbor, resulting in two fatalities.
Final Disposition
After the sinking in 1952, multiple salvage attempts were made but failed. The vessel’s enrollment was officially closed in January 1954. While many metal components have been removed, buried remains of the composite hull persist at the scuttled site.
Current Condition & Accessibility
The wreck lies in shallow harbor water, providing opportunities for divers to explore the remnants of early 20th-century dredging technology. The site is of historical and archaeological significance, reflecting the industrial heritage of the time.
