The reciprocating group displaced 1,010–1,030 long tons (1,030–1,050 t) at standard load and 1,305–1,325 long tons (1,326–1,346 t) at deep load The ships measured 225 feet (68.6 m) long overall with a beam of 35 feet 6 inches (10.8 m). They had a draught of 12 feet 3 inches (3.7 m). The ships' complement consisted of 85 officers and ratings.
The reciprocating ships 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 2,400 indicated horsepower (1,800 kW) and gave a maximum speed of 16.5 knots (30.6 km/h; 19.0 mph). They carried a maximum of 660 long tons (671 t) of fuel oil that gave them a range of 5,000 nautical miles (9,300 km; 5,800 mi) at 10 knots (19 km/h; 12 mph).
The Algerine class was armed with a QF 4 in (102 mm) Mk V anti-aircraft gun and four twin-gun mounts for Oerlikon 20 mm cannon. The latter guns were in short supply when the first ships were being completed and they often got a proportion of single mounts. By 1944, single-barrel Bofors 40 mm mounts began replacing the twin 20 mm mounts on a one for one basis. All of the ships were fitted for four throwers and two rails for depth charges.
She was built by the Port Arthur Shipbuilding Company at Port Arthur, Ontario, Canada, launched on 9 May 1944 and commissioned on 23 May 1944. In 1954 Mariner was on patrol in the North Sea as a fishery protection vessel, checking trawlers nets, and giving aid to any of the trawlers should they need it.
She was sold to the Burmese Navy and was reactivated at HM Dockyard Sheerness. She was handed over to Burma in the pools of London on 18 April 1958 and renamed Yang Myo Aung. She was fitted as a minelayer, carrying eight mines in each side.
She served in the Burmese Navy until 1982.
