Design and description
A British design, the Bangor-class minesweepers were smaller than the preceding s in British service, but larger than the in Canadian service. They came in two versions powered by different engines; those with a diesel engines and those with vertical triple-expansion steam engines. Quatsino was of the latter design and was larger than her diesel-engined cousins. Quatsino was 180 ft long overall, had a beam of 28 ft and a draught of 9 ft. The minesweeper had a displacement of 672 LT. She had a complement of 6 officers and 77 enlisted.

Quatsino had two vertical triple-expansion steam engines, each driving one shaft, using steam provided by two Admiralty three-drum boilers. The engines produced a total of 2400 ihp and gave a maximum speed of 16.5 kn. The minesweeper could carry a maximum of 150 LT of fuel oil.

Quatsino was armed with a single quick-firing (QF) 4 in/40 caliber Mk IV gun mounted forward. For anti-aircraft purposes, the minesweeper was equipped with one QF 2-pounder Mark VIII and two single-mounted QF 20 mm Oerlikon guns. As a convoy escort, Quatsino was deployed with 40 depth charges launched from two depth charge throwers and four chutes.

Operational history
The minesweeper was ordered as part of the 1939–40 building programme. The ship's keel was laid down on 20 June 1940 by Prince Rupert Dry Dock and Shipyards Co. at their yard in Prince Rupert, British Columbia. Named for Quatsino Sound in British Columbia, Quatsino was launched on 9 January 1941 and commissioned into the Royal Canadian Navy at Prince Rupert on 3 November 1941.

Quatsino spent the entirety of the Second World War on the West Coast of Canada. Assigned to the patrol units Esquimalt Force (operating out of Esquimalt, British Columbia) or Prince Rupert Force (operating out of Prince Rupert), the main duty of Bangor-class minesweepers after commissioning on the West Coast was to perform the Western Patrol. This consisted of patrolling the west coast of Vancouver Island, inspecting inlets and sounds and past the Scott Islands to Gordon Channel at the entrance to the Queen Charlotte Strait and back.

Following the war Quatsino was paid off on 26 November 1945 at Esquimalt. The vessel was sold for mercantile conversion in 1947 and renamed Chen Hsin. Registered in Shanghai the vessel was owned by Chung Yuan SN Co. The vessel was sold in 1950 to Transcontinental Corporation, registered in Monrovia and renamed Concord. The merchant ship was broken up in Hong Kong beginning on 13 January 1951.
