Buoy Tender Grenville at Kingston

Built in 1915 by Polson Iron Works as DGS Grenville, the lighthouse supply buoy tender was 164 feet long, 30 foot beam and 10 foot depth. Wintering after grounding in the winter of 1924-25, she was towed to Collingwood for refit. She was rebuilt with an enclosed wheelhouse after 1942. A wood frame above the fo'c's'le was used to rig a canvas awning. Grenville is shown in the CD&D drydock in a 1940's annual report.

A couple of vintage photos recently posted to the Vintage Kingston FB group included the Grenville at the Brock Street dock, mid-1960's:

The Grenville was the first vessel to transit the Iroquois Lock of the newly-opened St Lawrence Seaway. Another vessel shown in the Canadian Dredge & Dock drydock, likely the Amherst Island ferry of the time. Notice the dredge in background. Of note are CP boxcars on the former spile docks in the top photo (three of them) and one (below). The CD&D dredge and tugs are in the early grey-hull scheme.

Some other photos of Grenville. With Lambton at Parry Sound, awning rigged: 

The Prescott coast guard base with Grenville docked, 1950's. Note coal piles! In April of 1960, she spent two weeks placing navigational buoys from the Brock Street Dock for the Kingston area.

A nice 1961 view:

The Grenville was crushed by ice against a bridge abutment near Valleyfield in Lake St Francis on December 18, 1968.
