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.Chesneau, p. 64Macpherson and Barrie, p. 167 They came in two versions powered by different engines; those with a diesel engines and those with vertical triple-expansion steam engines. ''Clayoquot'' was of the latter design and was larger than her diesel-engined cousins. ''Clayoquot'' was long overall, had a beam of and a draught of . The minesweeper had a displacement of . She had a complement of 6 officers and 77 enlisted.

''Clayoquot'' 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 and gave a maximum speed of . The minesweeper could carry a maximum of of fuel oil.

''Clayoquot'' was armed with a single quick-firing (QF) /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, ''Clayoquot'' was deployed with 40 depth charges launched from two depth charge throwers and four chutes.Macpherson, p. 19

Construction and career

Ordered on 23 February 1940 as ''Esperanza'', the ship was renamed ''Clayoquot'' in 1940. ''Clayoquot'' was laid down on 20 June 1940 by Prince Rupert Dry Dock and Shipyards Co. at Prince Rupert, British Columbia. The minesweeper was launched on 3 October 1940 and commissioned on 22 August 1941 at Prince Rupert.

She left Esquimalt, British Columbia after working up and made her way to Halifax, Nova Scotia where she arrived on 14 November 1941. ''Clayoquot'' was made part of Halifax Local Defence Force initially, though she was transferred to the Western Local Escort Force (WLEF) in March 1942. In May 1942 ''Clayoquot'' was assigned to the Gulf Escort Force. On 7 July, while responding to a U-boat attack on a convoy in the Gulf of St. Lawrence, ''Clayoquot'' came upon the abandoned hulk of the merchant vessel ''Dinaric'', which had been torpedoed during the attack. ''Clayoquot'' sank the ship with gunfire and depth charges. On 10 September she was returning to Gaspé, Quebec after escorting a convoy to Rimouski with the corvette nearby when ''Charlottetown'' was hit by two torpedoes. ''Clayoquot'' searched for, but was unable to find the submarine. During depth charge attacks on possible targets, ''Clayoquot''s radio was knocked out and prevented the ship from informing command of the corvette's loss. She returned to the site of the sinking and was able to rescue 55 survivors, taking at least three and a half hours to complete. In October 1942 she joined Sydney Force.

On 29 December 1942 ''Clayoquot'' was sent for a major refit that took her from Halifax to Liverpool, Nova Scotia, to Pictou. The refit was completed in May 1943. After working up, she rejoined Sydney Force. In January 1944 she was assigned to as an officer training vessel for anti-submarine warfare. After ten months of training service, she was reassigned to Halifax Force.

Sinking

While sweeping for submarines near Sambro Island Light on 24 December 1944 in preparation to escort a convoy, ''Clayoquot'' was hit aft by a torpedo fired by .German, p. 179 She sank quickly and eight people died. There had not been enough time to disarm the depth charges kept ready, which detonated as the ship sank causing injuries among the surviving crew, which were picked up by the corvette .Darlington and McKee, pp. 196–199 The frigate and sister ship which had been accompanying ''Clayoquot'', were also targeted by the U-boat, but the torpedoes detonated before doing damage to the ships.Schull, p. 384 A large search force was sent out to deal with the U-boat however they were not successful in finding the submarine.
