Exact
According to this private correspondence, Exact was a US vessel. It sailed to Haida Gwaii in December 1851 in search of gold. It was presumed shipwrecked by Thomas Boys, from the evidence of pieces of a vessel that were found on the southwest side of Vancouver Island. It is not clear from the despatches if it did, in fact, flounder. Douglas, in this correspondence, refers to Exact's return to Victoria from Gold Harbour, unsuccessful in its search for gold.
