Stadacona was one of a number of American private yachts acquired by the RCN during the First World War. The vessel was
commissioned into the RCN on 13 August 1915.
Stadacona was then sent to the
Canadian Vickers shipyard in
Montreal, Quebec to fit out. The vessel was given one gun forward and a
12-pounder gun was added aft later in the war. The vessel then sailed to
Sydney, Nova Scotia to begin her career as a
patrol vessel in September. In 1916
Stadacona was among the vessels assigned to patrol the
Cabot Strait. The vessel became
flagship of the Canada's
East Coast fleet based at Halifax under Vice Admiral Sir
Charles Coke on 30 April 1916.
Stadacona remained flagship of the fleet after
Walter Hose took over command from Sir Charles Coke on 14 August. In August 1918 the German
U-boat captured the
fishing trawler Triumph off the East Coast of Canada. Using the trawler to get close to the Atlantic fishing fleets, the Germans sank several Canadian and American fishing trawlers.
Stadacona was among the vessels dispatched to deal with the submarine. However, the Germans
scuttled Triumph once the fishing trawler ran out of fuel. In early 1919
Stadacona, accompanied by a number of s, was sent to the
west coast via the
Panama Canal. She served as a
dispatch vessel until being
paid off on 31 March 1920, and transferred to government service. The vessel was then used primarily used for
hydrographic surveys and occasionally for fisheries patrol along the west coast until sold in 1924. ==Sale and subsequent career==
