Canadian Fairmile B


The Canadian Fairmile B was a type of motor launch originally designed for the Royal Navy by W.J. Holt of the British Admiralty and built by British boatbuilder Fairmile Marine. Affectionately known by their crews as The Little Ships, Little Fighting Ships, Q-Boats, MLs or Holy Rollers, during the Second World War eighty-eight Fairmile B boats, with slight modifications for Canadian climatic and operational conditions, were built in Canada for service with the coastal forces of the Royal Canadian Navy in home waters.

History

In the spring of 1940 Canada's Naval Staff realized that the RCN needed more vessels equipped with ASDIC sets for anti-submarine patrols in the St. Lawrence River and Pacific Coast. Learning “that the Admiralty was planning to build Type "B" Fairmile motor launches for such work in British waters”, the RCN began to investigate the comparative advantages of building and employing the Fairmile B in Canadian waters. By the end of 1940 with the first British Fairmile B motor launches completed, performance figures and a complete set of drawings and specifications were sent to Canada. Although unimpressed with the trial results that showed that the Fairmile B was not quite maneuverable at slow speeds required for the ASDIC to work correctly, the need for more anti-submarine vessels was so great that the Naval Staff proceeded with the program.
By April 1941, contracts for the first twenty-four Fairmile B boats was signed with seven builders in Ontario, three in British Columbia, and one in Nova Scotia for a “standard price for each vessel of $85,000 in the east and $76,000 in British Columbia.” Expected that the twenty-four boats would be delivered by the end of 1941, shortages of resources and components delayed builders efforts. As such, only thirteen Fairmiles built in the Great Lakes region were delivered in 1941, with only nine successfully arriving in Halifax and four laid up at Sarnia and Toronto due to winter storms. Once in Halifax, only four of the Fairmiles could be kept operational due to a general shortage of naval personnel and all other available crews being prioritized to corvettes and minesweepers.
In July 1941 the Naval Staff let out another contract for twelve MLs in order to help provide for the defence of Newfoundland and adjacent waters. Intended for anti-submarine patrols at St. John's, Botwood, and at Red Bay on the Strait of Belle Isle, continuing material shortages delayed the commissioning of these vessels to May and June 1942.

Design

Originally designated and painted up as CML 01–36, the Canadian Fairmile B was built of double mahogany wood with an eight-inch oak keel. Based on a line of destroyer hulls, they arrived in prefabricated kits, ready to be assembled for the RCN by a number of different boatyards. In contrast to the British built boats, the Canadian Fairmile was narrower, had a greater draught, and were slightly more powerful giving the Canadian boats a two knot speed advantage over the British boats. As one former Fairmile Captain described them, "sheathed for operation in ice and displacing 100 tons, they were indeed veritable Little Fighting Ships." Crewed by two or three officers and 14 sailors, accommodation on the Fairmile B was thought to be "cramped but comfortable".

Propulsion

With a fuel capacity of 2,320 gallons of 87 octane gasoline, the early Fairmiles were powered by two 650 hp engines, could reach a top speed of 20 knots, 16.5 knots sea speed and a range of 1925 miles at 7.5 knots. Later versions were fitted with larger 700 hp engines able to achieve a top speed to 22 knots, with a range of 1925 miles at 7.5 knots.

Armament

A unique design feature of the Fairmile B was that with forty-eight hours notice each boat could be reconfigured to serve in a different role. Fitted with steel strips and tapped holes to ease equipment swaps, weapons and specialist gear such as torpedo tubes, mines, depth charges, and guns could be quickly stripped and attached to the boat. In two days, a Fairmile could have its weapons and equipment reconfigured to serve as an escort, minesweeper, minelayer, navigation leader, coastal raider, patrol boat, ambulance or rescue launch.

Sensors

Each boat was equipped with sonar, radar and WIT.

Fairmile Flotillas

During the Second World War the Canadian Fairmile B of the RCN played a vital role escorting shipping along the St. Lawrence River, in the Gulf of St. Lawrence, and between Newfoundland and the mainland of Canada. Regularly deployed in flotillas of six The Little Ships relieved larger escort craft urgently needed elsewhere by carrying out anti-submarine patrols, port defence and rescue duties. Based out of shore establishments on the St. Lawrence River, Halifax, Saint John, Shelburne, Sydney and on the West Coast; at sea the RCN Fairmile Fleets were accompanied by two "mother ships" HMCS Preserver and HMCS Provider providing fresh water, fuel and medical services.

Canadian Fairmile Bs in foreign service

French Free Forces Fairmiles

In February 1943, ML Q052, Q062 and Q063 were transferred to the Free French Forces and stationed at St. Pierre and Miquelon under the command of Flag Officer, Newfoundland. After the war, the French Fairmiles were returned to the RCN.

American Fairmiles

Eight Canadian Fairmiles were built by Le Blanc for the RN and were transferred under Lend-Lease to the United States Navy as US coastal protection had been depleted by transferring ships to the Royal Navy for convoy work. The USN used the Canadian-built Fairmiles as submarine chasers.
