Tree-class trawlers were a class of anti-submarine naval trawlers which served in the Royal Navy during the Second World War. They were nearly identical to the s, of which they are usually considered a subclass. Six Tree-class trawlers were lost during the war: ''Almond, Ash, Chestnut, Hickory, Juniper'' and ''Pine''. One, ''Mangrove'', was transferred to Portugal in 1943. By the end of 1946, only ''Olive'' and ''Walnut'' remained in service with the Royal Navy. Both were sold in 1948.

Naval Trawler
Naval trawlers are vessels built along the lines of a fishing trawler but fitted out for naval purposes; they were widely used during the First and Second World Wars. Some—known in the Royal Navy as "Admiralty trawlers"— were purpose-built to naval specifications, others adapted from civilian use. Fishing trawlers were particularly suited for many naval requirements because they were robust vessels designed to work heavy trawls in all types of weather, and had large clear working decks. A minesweeper could be created by replacing the trawl with a mine sweep. Adding depth charge racks on the deck, ASDIC sonar below, and a or gun in the bow equipped the trawler for anti-submarine duties. History Armed trawlers were also used to defend fishing groups from enemy aircraft or submarines. The smallest civilian trawlers were converted to danlayers. Contemporary Some nations still use armed trawlers for fisheries protection and patrol. The Indian Navy used naval trawlers for ...

Norwegian Sea
The Norwegian Sea ( no, Norskehavet; is, Noregshaf; fo, Norskahavið) is a marginal sea, grouped with either the Atlantic Ocean or the Arctic Ocean, northwest of Norway between the North Sea and the Greenland Sea, adjoining the Barents Sea to the northeast. In the southwest, it is separated from the Atlantic Ocean by a submarine ridge running between Iceland and the Faroe Islands. To the north, the Jan Mayen Ridge separates it from the Greenland Sea. Unlike many other seas, most of the bottom of the Norwegian Sea is not part of a continental shelf and therefore lies at a great depth of about two kilometres on average. Rich deposits of oil and natural gas are found under the sea bottom and are being explored commercially, in the areas with sea depths of up to about one kilometre. The coastal zones are rich in fish that visit the Norwegian Sea from the North Atlantic or from the Barents Sea (cod) for spawning. The warm North Atlantic Current ensures relatively stable and high wa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Vessels built to Admiralty specifications for RN use were known as Admiralty trawlers. All trawlers operated by the RN, regardless of origin, were typically given the prefix HMT, for "His Majesty's Trawler". Summary First World War The trawler Viola, built in 1906 at Hull and requisitioned September 1914 is the oldest surviving steam trawler in the world. She is currently beached at Grytviken in South Georgia, though there are currently plans to return her to Hull.

SS Walnut
SS ''Walnut'' was a refugee ship converted from a British minesweeping Tree-class trawler which carried Baltic refugees from Sweden to Canada in 1948. The refugees' arrival at Pier 21 in Halifax, Nova Scotia led to a controversy which played an important role in shaping Canada's postwar refugee policies. Initially entering service during the Second World War as HMS ''Walnut'', the trawler was sold for commercial purposes following the war. Converted for use as a cargo ship, the vessel retained the name ''Walnut'' until 1959 when sold and renamed ''Keta''. The ship was Ship breaking, broken up in 1976.

Leith
Leith (; gd, Lìte) is a port area in the north of the city of Edinburgh, Scotland, founded at the mouth of the Water of Leith. In 2021, it was ranked by '' Time Out'' as one of the top five neighbourhoods to live in the world. The earliest surviving historical references are in the royal charter authorising the construction of Holyrood Abbey in 1128 in which it is termed ''Inverlet'' (Inverleith).
