Design and description

The Naval Large Tugs, prefixed Canadian Forces Auxiliary Vessel (CFAV), will replace the five Glen-class tugs and the fire and rescue boat CFAV Firebrand which were brought into service in the mid-1970s. The Glen-class tugs which the NLTs are replacing have a bollard pull of 18 metric tons (18 long tons ; 20 short tons ) and 850 horsepower (630  kW ) on each side. The NLTs have much increased power at 60 metric tons (59 long tons; 66 short tons) of bollard pull and Azimuth stern drive propulsion with 4,988 horsepower (3,720 kW) per side. [1] The NLTs will measure 24.40 metres (80 ft 1 in) long overall with a moulded beam of 11.25 metres (36 ft 11 in) and a draught of 5.40 metres (17 ft 9 in). They will be powered by a two MAN 12V175D-MM diesel engines. They will have a maximum speed of 12 knots (22 km/h; 14 mph) and have a crew of six. [2]

Construction and career

On 29 April 2019, Groupe Ocean was awarded a $102 million contract for four tugboats to be built at their shipyard at L'Isle-aux-Coudres as part of the National Shipbuilding Strategy. [3] The build cost of the four NLTs later rose to $121 million. In December 2021, the Government of Canada announced the names for the four ships, Haro, Barkerville, Canso, and Stella Maris. [4] Two of the ships, Haro and Canso commemorate important straits in Canadian waters while Barkerville and Stella Maris commemorate tugboats that were lost or damaged in service in Canadian waters. [1] The steel cutting for the first NLT commenced in September 2020, with main construction beginning in November. They were initially expected to completed in 2022, [5] however, supply chain issues delayed their completion. [6] The lead ship, CFAV Haro, was launched on 15 July 2022. [1] [7] Upon completion, two of the ships, Haro and Barkerville, will serve on the west coast and Canso and Stella Maris will operate on the east coast. [1]

Type V ships were used to move ships and barges. Type V tugboats were made of either steel or wood hulls. There were four types of tugboats ordered for World War II. The largest type V design was the sea worthy 186-foot (57 m) long steel hull, V4-M-A1. The V4-M-A1 design was used by a number of manufacturers; a total of 49 were built. A smaller steel hull tugboat was the 94-foot (29 m) V2-ME-A1; 26 were built. The largest wooden hull was the 148-foot (45 m) V3-S-AH2, of which 14 were built.

Everett-Pacific Shipbuilding & Dry Dock Company was established in 1942 to build ships needed for World War II. Yard construction began on 1 March 1942. As part of the Emergency Shipbuilding Program, the US Navy provided some of the capital to start Everett-Pacific Shipbuilding at Port Gardner Bay in Everett, Washington. Everett-Pacific was sold in 1945 to the Pacific Car and Foundry, who was already a major manufacturer of railcars and trucks. Pacific Car and Foundry was building barges for the US Navy during World War II at plants in Renton, Seattle and Tacoma in the state of Washington. The lease for the shipyard in Everett, Washington ended in 1949 and the yard closed. Pacific Car and Foundry in 1972 changed its name to Paccar Inc. to reflect its major products. The Everett-Pacific shipyard site later became part of Western Gear, a heavy machinery manufacturer. From 1987 to 1992, the shipyard was rebuilt to become part of Naval Station Everett. Everett-Pacific Shipbuilding was started by William Pigott Jr. a Seattle businessmen and his brother Paul Pigott (1900-1961). William Pigott Jr. was born in 26 Aug. 1895 in Pueblo, CO and died on 8 July 1947 in San Francisco, CA.
