Isles-class trawler

The Isles class was a group of naval trawlers built for the Royal Navy, and also used by the Royal Canadian Navy and the Royal New Zealand Navy, during the Second World War. The type covers 197 vessels built between 1939 and 1945 in the nearly identical Isles, Dance, Tree and Shakespearian classes, and was mainly used for minesweeping and harbour defence. Most carried one 12-pounder gun and three or four 20 mm Oerlikon guns with 30 depth charges. Twenty-three were lost during the war. After 1945 some were disarmed as wreck disposal vessels or used as danlayers, and a few served on into the 1960s, with two Federal German Navy examples working as training vessels into the 1970s. Eighteen yards built them, among them A. & J. Inglis of Glasgow.
