Charleston (U.S.S.) (II)

Charleston was stripped down to the waterline and then sold to the Powell River Company, Ltd. On 25 October 1930, the ship was towed to Powell River, British Columbia, Canada, to serve as a floating breakwater for a large logging mill. The hulk was ballasted, anchored and periodically pumped out to keep her afloat. The following year, this vessel was joined by the hull of the cruiser Huron (formerly South Dakota).

In 1961, heavy weather caused the Charleston to partially flood, and her hull was towed to Kelsey Bay, on the north coast of Vancouver Island. The hulk was run ashore to serve as a breakwater.
