The '''''Llewellyn''-class minesweepers''' were a series of ten coastal [[minesweeper]]s constructed for the [[Royal Canadian Navy]] during the [[World War II|Second World War]]. Based on the Admiralty type {{sclass2-|MMS|minesweeper|2}}, the ''Llewellyn'' class were constructed of wood and used for the removal of [[Naval mine#Influence mines|magnetic influence mines]]. Two were built in [[Quebec]], with the eight constructed on the [[British Columbia Coast|Western Coast of Canada]]. Mostly used as [[guard ship]]s during the war, only three of the ten remained in Royal Canadian Navy service following the war, with the last being discarded in 1957. Following naval service, vessels of the class ended up in commercial service, with some becoming fishing vessels, cargo ships and one a floating restaurant. Six of the ten ships were lost in commercial service.
==Description==
Based on the Admiralty type {{sclass2-|MMS|minesweeper}}s, the ''Llewellyn'' class were built with wooden hulls for deployment against [[Naval mine#Influence mines|magnetic influence mines]] that would detect a steel hull passing nearby and detonate. The minesweepers had a [[Displacement (ship)|standard displacement]] of {{convert|228|LT|t}}.{{sfn|Macpherson|1997|p=102}} They were {{convert|119|ft|4|in|m|1|abbr=on}} [[Length overall|long overall]] and {{convert|105|ft|0|in|m|0|abbr=on}} [[Length between perpendiculars|between perpendiculars]] with a [[Beam (nautical)|beam]] of {{convert|22|ft|0|in|m|1|abbr=on}} and a [[Draft (hull)|draught]] of {{convert|8|ft|8|in|m|1|abbr=on}}.{{sfn|Lenton|Colledge|1968|p=534}}{{sfn|Macpherson|Barrie|2002|p=201}} The ''Llewellyn'' class were powered by a [[diesel engine]] driving one [[propeller]] shaft, rated at {{convert|500|bhp|lk=in|0}}.{{sfn|Lenton|Colledge|1968|p=534}} This gave the minesweepers a maximum speed of {{convert|12|kn|lk=in|0}}.{{sfn|Macpherson|Barrie|2002|p=201}}
The ''Llewellyn'' class were armed with four {{convert|0.5|in|mm|abbr=on|1}} machine guns placed in two twin mounts.{{sfn|Macpherson|Barrie|2002|p=201}} At some point, their armament was changed to one 0.5-inch machine gun placed amidships and twin {{convert|.303|in|mm|1|adj=on}} machine guns on the [[Bridge (nautical)|bridge]] wings.{{sfn|Macpherson|1997|p=102}} The minesweepers were equipped with the "Double L" magnetic minesweeping gear and had a [[Ship's company|complement]] of 23 composed of 3 officers and 20 crew.{{sfn|Macpherson|Barrie|2002|p=201}}
