My father, Stanley Cossey, was a naval architect who went to work for German and Milne in Montreal where he was the head of the design team for the Norton Class navy tugs. In 1943 he moved to Russel Brothers in Owen Sound and eventually was appointed as the head of the drafting department.

H.M.C.S. Riverton (W.47; ATA.528) was built in 1944 by Canadian Bridge Co. at Walkerville ON for the Royal Canadian Navy. She was 104.5’ x 26.8’ x 11.2’ with a steel hull 257gt 19.17rt. She was powered by a 1–1000bhp, 19.55nhp Sulzer diesel engine by Dominion Engineering Co. Ltd. Lachine, QC.

In 1944 she was commissioned as H.M.C.S. Riverton. After the Second World War she became an auxiliary vessel as C.N.A.V. Riverton, later designated as C.F.A.V. Riverton. In 1979 as the Techno St. Laurent she was sold to Techno Maritime Lt., Sillery, QC. In 2002 as the Kristin she was sold to McKeil Marine Limited, Hamilton ON. In 2006 she was sold to International Marine Salvage, Port Colborne, ON.

Jeff Cameron (Knowyourtugs) reports that "she was in the Marine Recycling scrapyard in Port Colborne ON on July 6th, 2018. She has been at the yard for over a decade in an ever declining state of repair. Having been partly scrapped a few years ago she has finally been dragged ashore. She is surely now, not long from being entirely cut up."
