HMCS Arleux was one of twelve Battle-class naval trawlers used by the Royal Canadian Navy (RCN). Entering service in 1918 near the end of the First World War, the vessel had a short career with the RCN, being transferred to the Department of Marine and Fisheries in 1922. Arleux was used for fisheries patrol off the east coast of Canada until 1939, when the ship was reacquired by the RCN at the onset of the Second World War. Used as a gate vessel during the war and designated Gate Vessel 16, the ship was sold for mercantile purposes following the war. The ship foundered in 1948 off the coast of Nova Scotia.
HMCS St Julien was one of twelve Battle-class naval trawlers constructed for and used by the Royal Canadian Navy (RCN) during the First World War. Following the war the ship was transferred to the Canadian Department of Marine and Fisheries and converted into a lightvessel. Re-designated Lightship No. 22, the ship remained as such until 1958. The ship was sold for commercial use and renamed Centennial and was in service until 1978.
Vorpostenboot, also referred to as VP-Boats, flakships or outpost boats, were German patrol boats which served during both World Wars. They were used around coastal areas and in coastal operations, and were tasked with – among other things – coastal patrol, ship escort, and naval combat.
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 3-inch (76 mm) or 4-inch (102 mm) gun in the bow equipped the trawler for anti-submarine duties.
USS Oceanographer (AGS-3) was a survey ship of the United States Navy during World War II that produced charts chiefly of passages in the Solomon Islands area of the Pacific Ocean. Upon transfer to the Navy, she had initially briefly been named and classed as gunboat USS Natchez (PG-85). Before her World War II Navy service, she had been USC&GS Oceanographer (OSS-26), a survey ship with the U.S. Coast and Geodetic Survey from 1930.
An armed yacht was a yacht that was armed with weapons and was typically in the service of a navy. The word "yacht" was originally applied to small, fast and agile naval vessels suited to piracy and to employment by navies and coast guards against smugglers and pirates. Vessels of this type were adapted to racing by wealthy owners. The origin of civilian yachts as naval vessels, with their speed and maneuverability, made them useful for adaptation to their original function as patrol vessels. In the United States Navy armed yachts were typically private yachts expropriated for government use in times of war. Armed yachts served as patrol vessels during the Spanish–American War and the World Wars. In the latter conflicts, armed yachts were used as patrol vessels, convoy escorts, and in anti-submarine duties. In the United States, yachts were purchased from their owners with the owners given an option to repurchase their yacht at the close of hostilities.
The first USS Vedette (SP-163) was a commercial yacht built in 1899. At the outbreak of World War I, the yacht was leased by the United States Navy, and was used as a section patrol craft in the North Atlantic Ocean. She served honorably during the war, rescuing survivors at sea, and attacking a German U-boat. At war’s end, she was converted to her original configuration and returned to her owner, the railroad executive, financier, and philanthropist Frederick W. Vanderbilt (1856-1938) of New York City.
USS Christabel (SP-162) was a civilian steam yacht that was built in Glasgow in 1893 for a Scottish industrialist. She had an American owner by 1910, served as a United States Navy patrol ship in the latter part of the First World War, and afterward was returned to US civilian service.
USS Noma (SP-131) was the private steam yacht Noma, built in 1902 on Staten Island and loaned to the U.S. Navy during World War I as a patrol craft assigned to protect shipping from German submarines. At war’s end she served the American Relief Commission in Constantinople and the Black Sea before being returned to her owner after decommissioning. In the 1930s she was converted to a salvage tug, owned in Italy as Salvatore Primo, and torpedoed during World War II.
USS James (SP-429) — also known as USS W. T. James (SP-429) — was a steam trawler acquired by the United States Navy during World War I. She was converted into an armed minesweeper and assigned to the European Theater, where she performed varied tasks, including minesweeping, patrolling, and escorting of larger ships in convoy. In 1919, while returning to the United States, she was severely damaged in a storm off the French coast, and sank. Her crew were rescued.
USS Druid (SP-321) was a private yacht launched 10 February 1902 as Rheclair that was built for Daniel G. Reid. Reid sold the yacht to Senator Nelson W. Aldrich who renamed the yacht Nirvana only just over a year before his death. Aldrich's estate chartered Nirvana to John Wanamaker until it was bought by his son Rodman Wanamaker who used the yacht for cruising until a fire on 14 December 1916, just before a cruise south, severely damaged the vessel. He chartered an alternate vessel for his trip south and, after full repairs, the yacht was sold to Walter W. Dwyer who gave it the name Druid with intentions to sell the yacht to the government in order to finance a shipyard venture in Pensacola, Florida.
USS Margaret (SP-328) was a menhaden fishing trawler acquired by the U.S. Navy during World War I. She was configured by the Navy as a Section mine sweeper. Post-war she was sold resuming commercial fishing as Margaret. With World War II the vessel was acquired by the U.S. Coast Guard serving from December 1942 to June 1943 as an emergency manned vessel. Margaret resumed menhaden fishing and was shown as active in the U.S. register as late as 1968.
USS Utowana (SP-951) – also known as USS Victorine (SP-951) -- was a fishing trawler acquired by the U.S. Navy during World War I. The Navy had planned to use her as a minesweeper based out of Kittery, Maine; however, Utowana spent most of her service time operating as an armed patrol craft, responsible for escorting Allied ships across the dangerous North Atlantic Ocean. She served through the war and the armistice before returning to the United States for decommissioning.
USS Wakiva II (SP-160), often referred to as USS Wakiva, was an armed yacht that served in the United States Navy from 1917 to 1918 and saw combat in World War I. She was originally the yacht SS Wakiva II built for Lamon V. Harkness in Scotland.
USS Anderton (SP-530), originally to have been USS Raymond J. Anderton (SP-530), was a patrol vessel and minesweeper that served in the United States Navy from 1917 to 1919.
The first USS Courtney (SP-375) was a patrol boat and minesweeper in commission in the United States Navy from 1917–1919.
Aphrodite was a yacht built to requirements by owner Colonel Oliver H. Payne of New York City as an ocean going steam yacht with barque rig and capable of good speed under sail alone. The yacht was launched 1 December 1898 and completed in 1899 to be the largest American built steam yacht at the time. The yacht served in the United States Navy as the patrol vessel USS Aphrodite from May 1917 to July 1919. The yacht was given the designation SP-135 for Section patrol and was, unlike the majority of section patrol vessels, sent overseas rather than acting in that capacity in home waters. The yacht was returned to private service after the war.
USS G. H. McNeal (SP-312), also called George H. McNeal, was a United States Navy minesweeper in commission from 1917 to 1919.
USS Amagansett (SP-693) was a United States Navy patrol vessel and minesweeper in commission from 1917 to 1920.
Junella was a fishing trawler, best known for her service with the Royal Navy during the Falklands War. She was built in 1975 for J Marr & Son, a Hull-based fishing company. On 11 April 1982 she was taken up from trade by the British government and commissioned into the Royal Navy. She was fitted with Second World War era minesweeping gear at Rosyth Dockyard, manned by Royal Navy sailors and allocated to the 11th Mine Countermeasures Squadron. She sailed on 26 April but was unable to commence sweeping until after the 14 June Argentine surrender. In the meantime she was utilised to transfer troops and stores between ships and landed special forces troops at San Carlos. Demining operations commenced on 21 June. Junella returned to the United Kingdom on 11 August, carrying a defused Argentine mine.
