Mersey-class Trawler
The Mersey class was a class of Admiralty trawlers built for the Royal Navy (or other government institutions) prior to World War II. Many went on to be used in various roles during World War II. The ships constituting this class were built as standard Mersey class or as non-standard class vessels. Characteristics The Mersey-class trawlers were purpose-built, standard Admiralty design intended for patrol, ASW and minesweeping roles. HMT ''John Quilliam'', delivered in June 1917, was the first of the standard completions. The smallest of the non-standard ships measured in length with a beam Beam may refer to: Streams of particles or energy *Light beam, or beam of light, a directional projection of light energy **Laser beam *Particle beam, a stream of charged or neutral particles **Charged particle beam, a spatially localized grou ....

Cochrane Shipbuilders
Cochrane Shipbuilders was a shipbuilder at Selby. History Founded by Andrew Cochrane at Beverley, England in 1884, establishing Cochrane & Sons in 1896. The ship building company moved to Selby in 1898. During the Second World War the company was one of the contractors engaged in building the Mulberry harbour units.Hartcup, p. 94 The yard passed into the ownership of the Ross Group in 1965, and later to the Drypool Group in 1969. The yard was then bought by United Towing Company and in 1977 the company’s name changed to Cochrane Shipbuilders. The North British Maritime Group was taken over by the Howard Smith Group in 1987. The yard closed in October 1992 and the equipment was auctioned off in 1993.

Ferguson Marine
Ferguson Marine (Port Glasgow) Limited is a shipbuilding company whose yard, located in Port Glasgow on the Firth of Clyde in Scotland, was established in 1903. It is the last remaining shipbuilder on the lower Clyde and is currently the only builder of merchant ships on the river. For some years the company's mainstay has been Roll-on/roll-off ferries, primarily for Caledonian MacBrayne (CalMac), including a series of innovative hybrid diesel-electric/battery-powered vessels. Beset with difficulties since 2018 over their latest two CalMac ferries, Fergusons' largest ever vessel, the shipyard was nationalised in December 2019. It is now classified as an executive non-departmental public body of the Scottish Government. History The Ferguson shipyard was founded as a partnership by four Ferguson Brothers (Peter, Daniel, Louis and Robert) who left the Fleming & Ferguson shipyard in Paisley to lease the Newark yard in Port Glasgow in March 1903. Ferguson Brothers acquired the fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lobnitz
Lobnitz & Company was a Scottish shipbuilding company located at Renfrew on the River Clyde, west of the Renfrew Ferry crossing and east of the confluence with the River Cart. The Lobnitz family lived at Chapeltoun House in East Ayrshire. The company built dredgers, floating docks, fishing boats, tugs and workboats. History The company was descended from Coulburn Lobnitz & Company, established in 1874, and the adjacent shipyard of William Simons & Co, established in 1860. Both builders specialised in the construction of dredgers and hopper barges. The two companies amalgamated in 1957 as Simons-Lobnitz Ltd. Faced with declining business the Renfrew yard finally closed in 1964 after some 1300 dredgers as well as barges and tugs had been built at the site. One late example survives: SS ''Shieldhall'' was built as a Clyde sludge boat in 1954 with reciprocating steam engines, and now operates as a pleasure cruiser on the Solent. Also still afloat is the ''William C. Daldy' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

British Admiralty
The Admiralty was a department of the Government of the United Kingdom responsible for the command of the Royal Navy until 1964, historically under its titular head, the Lord High Admiral – one of the Great Officers of State. For much of its history, from the early 18th century until its abolition, the role of the Lord High Admiral was almost invariably put "in commission" and exercised by the Lords Commissioner of the Admiralty, who sat on the governing Board of Admiralty, rather than by a single person. The Admiralty was replaced by the Admiralty Board in 1964, as part of the reforms that created the Ministry of Defence and its Navy Department (later Navy Command). Before the Acts of Union 1707, the Office of the Admiralty and Marine Affairs administered the Royal Navy of the Kingdom of England, which merged with the Royal Scots Navy and the absorbed the responsibilities of the Lord High Admiral of the Kingdom of Scotland with the unification of the Kingdom of Great ...

Royal Navy
The Royal Navy (RN) is the United Kingdom's naval warfare force. Although warships were used by English and Scottish kings from the early medieval period, the first major maritime engagements were fought in the Hundred Years' War against France. The modern Royal Navy traces its origins to the early 16th century; the oldest of the UK's armed services, it is consequently known as the Senior Service. From the middle decades of the 17th century, and through the 18th century, the Royal Navy vied with the Dutch Navy and later with the French Navy for maritime supremacy. From the mid 18th century, it was the world's most powerful navy until the Second World War. The Royal Navy played a key part in establishing and defending the British Empire, and four Imperial fortress colonies and a string of imperial bases and coaling stations secured the Royal Navy's ability to assert naval superiority globally. Owing to this historical prominence, it is common, even among non-Britons, to ref ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Beam (nautical)
The beam of a ship is its width at its widest point. The maximum beam (BMAX) is the distance between planes passing through the outer extremities of the ship, beam of the hull (BH) only includes permanently fixed parts of the hull, and beam at waterline (BWL) is the maximum width where the hull intersects the surface of the water. Generally speaking, the wider the beam of a ship (or boat), the more initial stability it has, at the expense of secondary stability in the event of a capsize, where more energy is required to right the vessel from its inverted position. A ship that heels on her ''beam ends'' has her deck beams nearly vertical. Typical values Typical length-to-beam ratios ( aspect ratios) for small sailboats are from 2:1 (dinghies to trailerable sailboats around ) to 5:1 (racing sailboats over ). Large ships have widely varying beam ratios, some as large as 20:1. Rowing shells designed for flatwater racing may have length to beam ratios as high as 30:1, while a cor ...

The QF 4-inch gun Mks I, II, IIII.e. Mark 1, 2 and 3. Britain used Roman numerals to denote Marks (models) of ordnance until after World War 2. Hence this article describes the first three models of British QF 4-inch guns. were early British QF (quick-firing) naval guns originating in 1895. They all had barrels of 40 Caliber#Caliber as measurement of length, calibres length. Naval service The gun was intended to be a more powerful alternative to the quick-firing 3-inch QF 12 pounder 12 cwt naval gun, QF 12-pounder gun, and a faster-firing replacement for the BL 4 inch naval gun Mk I – VI, BL 4-inch gun. It was mounted on the following ships : * third-class protected cruisers of 1896 * s of 1898 * s of 1900 * third-class cruisers, launched in 1903 * s of 1906 Its shell proved insufficiently powerful to make it much of an improvement on the 12-pounder. From 1907 onwards it was succeeded in its class on new warships by the BL 4 inch naval gun Mk VIII, BL 4 inch gun Mk VIII, whi ...

QF 6-pounder Hotchkiss
The Ordnance QF Hotchkiss 6 pounder gun Mk I and Mk II or QF 6 pounder 8 cwt were a family of long-lived light naval guns introduced in 1885 to defend against new, small and fast vessels such as torpedo boats and later submarines. There were many variants produced, often under license which ranged in length from 40 to 58 calibers, but 40 caliber was the most common version. 6-pounders were widely used by the navies of a number of nations and often used by both sides in a conflict. Due to advances in torpedo delivery and performance, 6-pounder guns were rapidly made obsolete and were replaced with larger guns aboard most larger warships. This led to their being used ashore during World War I as coastal defense guns, the first tank guns and as anti-aircraft guns, whether on improvised or specialized HA/LA mounts. During World War II 6-pounder guns were put back in service to arm small warships and as coastal defense guns. The last ships to carry 6-pounders were the Aegir-cl ...

RV George Bligh
RV ''George Bligh'' (LO309) was a fisheries research vessel that was operated by the Directorate of Fisheries, now known as the Centre for Environment, Fisheries and Aquaculture Science (Cefas). Originally built as an Admiralty for use in the First World war ''George Bligh'' was registered in London but based at the port of Lowestoft, on the East Anglian coast. Like some other the Mersey-class naval trawlers were given names taken from the roll-call of Nelson's ship . ''George Bligh'' was named after Captain George Miller Bligh (1780–1834), an officer of the Royal Navy, who saw service during the French Revolutionary and Napoleonic Wars, eventually rising to the rank of captain. He was present aboard HMS ''Victory'' at the Battle of Trafalgar, and was badly wounded during the action.Russell, E.S (1929) The work of the fisheries laboratory, Lowestoft.

Belgian Ship A4
Patrol vessel ''A4'' (french: link=no, Patrouilleur A4) was a small operated by Belgium during the Second World War. Originally built for the British Royal Navy, as HMS ''John Ebbs'', the ship is notable for its role in evacuating Belgian gold reserves to England during the Battle of Belgium in May 1940. The success of the operation not only allowed the Belgian government in exile to fund its operations but deprived the German occupiers of an important asset to support their war effort. After the Belgian surrender, the vessel and its crew interned themselves in neutral Spain. Both crew and vessel were released in 1946 and ''A4'' was scrapped soon afterwards. Background ''Pilote 4'' (later renamed ''Patrouilleur A4'') was purchased by the Belgian ''Corps de Marine'' in 1920, having previously served in the British Royal Navy during the First World War as HMS ''John Ebbs'' (FY3566). The vessel was a Mersey-class naval trawler, built by Cochranes in Selby, North Yorkshire, and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
