Cheerful-class Gunboat
The ''Cheerful''-class gunboat was a class of twenty gunboats built for the Royal Navy in 1855 for use in the Crimean War. Design The ''Cheerful'' class was designed by W.H. Walker (who also designed the preceding and classes). The ships were of particularly shallow draft for coastal bombardment in the shallow waters of the Baltic and Black Sea during the Crimean War.

Builder's Old Measurement
Builder's Old Measurement (BOM, bm, OM, and o.m.) is the method used in England from approximately 1650 to 1849 for calculating the cargo capacity of a ship. It is a volumetric measurement of cubic capacity. It estimated the tonnage of a ship based on length and maximum beam (nautical), beam. It is expressed in "tons burden" ( en-em , burthen , enm , byrthen ), and abbreviated "tons bm". The formula is: : \text = \frac where: * ''Length'' is the length, in foot (length), feet, from the stem (ship), stem to the sternpost; * ''Beam (nautical), Beam'' is the maximum beam, in feet. The Builder's Old Measurement formula remained in effect until the advent of steam propulsion. Steamships required a different method of estimating tonnage, because the ratio of length to beam was larger and a significant volume of internal space was used for boilers and machinery. In 1849, the Moorsom System was created in the United Kingdom. The Moorsom system calculates the cargo-carrying capaci ...

Sheerness Dockyard
Sheerness Dockyard also known as the Sheerness Station was a Royal Navy Dockyard located on the Sheerness peninsula, at the mouth of the River Medway in Kent. It was opened in the 1660s and closed in 1960. Location In the Age of Sail, the Royal Navy would often establish shore facilities close to safe anchorages where the fleet would be based in home waters. This was the case when, around 1567, a Royal Dockyard was established at Chatham, Kent, on the bank of the River Medway. At that time, HM Ships would often lay at anchor either within the river, on Chatham Reach or Gillingham Reach, or beyond it, around The Nore. Chatham Dockyard had its disadvantages, however. The vagaries of wind and tide, coupled with the restricted depth of the river, meant that vessels entering the river, for repairs or to replenish supplies at Chatham, could be delayed for considerable lengths of time. What was an inconvenience at times of peace became a serious impediment at times of war; and ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Gunboat Classes
A gunboat is a naval watercraft designed for the express purpose of carrying one or more guns to bombard coastal targets, as opposed to those military craft designed for naval warfare, or for ferrying troops or supplies. History Pre-steam era In the age of sail, a gunboat was usually a small undecked vessel carrying a single smoothbore cannon in the bow, or just two or three such cannons. A gunboat could carry one or two masts or be oar-powered only, but the single-masted version of about length was most typical. Some types of gunboats carried two cannons, or else mounted a number of swivel guns on the railings. The small gunboat had advantages: if it only carried a single cannon, the boat could manoeuvre in shallow or restricted areas – such as rivers or lakes – where larger ships could sail only with difficulty. The gun that such boats carried could be quite heavy; a 32-pounder for instance. As such boats were cheap and quick to build, naval forces favoured swarm ...

Pembroke Dockyard
Pembroke Dockyard, originally called Pater Yard, is a former Royal Navy Dockyard in Pembroke Dock, Pembrokeshire, Wales. History It was founded in 1814, although not formally authorized until the Prince Regent signed the necessary Order in Council on 31 October 1815, and was known as ''Pater Yard'' until 1817. The Mayor of Pembroke had requested the change "in deference to the town of Pembroke some distant". The site selected for the dockyard was greenfield land and the closest accommodations were in Pembroke. Office space was provided by the old frigate after she was beached. The Royal Marine garrison was housed in the hulked 74-gun ship, , after she was run aground in 1832. Many of the workmen commuted by boat from nearby communities until Pembroke Dock town was built up. In 1860 the dockyard's policing was transferred to the new No. 4 Division of the Metropolitan Police, which remained in that role until the 1920s. After the end of the First World War, the dockyard ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

HMNB Devonport
His Majesty's Naval Base, Devonport (HMNB Devonport) is one of three operating bases in the United Kingdom for the Royal Navy (the others being HMNB Clyde and HMNB Portsmouth) and is the sole nuclear repair and refuelling facility for the Royal Navy. The largest naval base in Western Europe, HMNB Devonport is located in Devonport, in the west of the city of Plymouth, England. The base began as Royal Navy Dockyard in the late 17th century, but shipbuilding ceased at Devonport in the early 1970s, although ship maintenance work has continued. The now privatised maintenance facilities are operated by Babcock International Group, who took over the previous owner Devonport Management Limited (DML) in 2007. DML had been running the Dockyard since privatisation in 1987. From 1934 until the early 21st century the naval barracks on the site was named HMS ''Drake'' (it had previously been known as HMS ''Vivid'' after the base ship of the same name).

Limehouse
Limehouse is a district in the London Borough of Tower Hamlets in East London. It is east of Charing Cross, on the northern bank of the River Thames. Its proximity to the river has given it a strong maritime character, which it retains through its riverside public houses and steps, such as The Grapes and Limehouse Stairs. It is part of the traditional county of Middlesex. It became part of the ceremonial County of London following the passing of the Local Government Act 1888, and then part of Greater London in 1965. It is located between Stepney to the west and north, Mile End and Bow to the northwest, Poplar to the east, and Canary Wharf and Millwall to the south, and stretches from the end of Cable Street and Butcher Row in the west to Stainsby Road near Bartlett Park in the east, and from West India Dock (South Dock) and the River Thames in the south to Salmon Lane and Rhodeswell Road in the north. The area gives its name to Limehouse Reach, a section of the Thames wh ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Greenwich
Greenwich ( , ,) is a town in south-east London, England, within the ceremonial county of Greater London. It is situated east-southeast of Charing Cross. Greenwich is notable for its maritime history and for giving its name to the Greenwich Meridian (0° longitude) and Greenwich Mean Time. The town became the site of a royal palace, the Palace of Placentia from the 15th century, and was the birthplace of many Tudors, including Henry VIII and Elizabeth I. The palace fell into disrepair during the English Civil War and was demolished to be replaced by the Royal Naval Hospital for Sailors, designed by Sir Christopher Wren and his assistant Nicholas Hawksmoor. These buildings became the Royal Naval College in 1873, and they remained a military education establishment until 1998 when they passed into the hands of the Greenwich Foundation. The historic rooms within these buildings remain open to the public; other buildings are used by University of Greenwich and Trinity Laban C ...

John Laird Sons & Company
Cammell Laird is a British shipbuilding company. It was formed from the merger of Laird Brothers of Birkenhead and Johnson Cammell & Co of Sheffield at the turn of the twentieth century. The company also built railway rolling stock until 1929, when that side of the business was separated and became part of the Metropolitan-Cammell Carriage & Wagon Company. History Formation from merger of Laird Company and Cammell & Co. The Laird Company was founded by William Laird, who had established the Birkenhead Iron Works in 1824. When he was joined by his son, John Laird in 1828, their first ship was an iron barge. John realised that the techniques of making boilers could be applied to making ships. The company soon became pre-eminent in the manufacture of iron ships and also made major advances in propulsion. In 1860, John Laird was joined in the business by his three sons, renaming the company John Laird, Sons & Co. The sons continued the business after their father's death in 187 ...

Blackwall, London
Blackwall is an area of Poplar, in the London Borough of Tower Hamlets, East London. The neighbourhood includes Leamouth and the Coldharbour conservation area. The area takes its name from a historic stretch of riverside wall built along an outside curve of the Thames, to protect the area from flooding. While mostly residential, the Poplar Dock and Blackwall Basin provide moorings for vessels. Setting and administration The area's significance derived from its position on an outside curve of the Thames, where currents slowed down, making it a sheltered spot useful to a range of shipping activities. This sheltered position was enhanced by the presence of the Blackwall Rock reef, though this could also be a danger to shipping. A further advantage of the area was that it lay east of the Isle of Dogs, so loading and unloading here avoided that time and effort of sailing round that peninsula to London, while still being very close to the City of London.

Haslar
Haslar is on the south coast of England, at the southern tip of Alverstoke, on the Gosport peninsula, Hampshire. It takes its name from the Old English , meaning "hazel-landing place". It may have been named after a bank of hazel strewn on marshy grounds around Haslar Creek to make it passable and habitable in old times, or merely because hazel grew there. Royal Hospital Haslar The location consists principally of the former Royal Hospital Haslar site, now luxury housing. The site for Haslar hospital was bought in 1745; before that the land was Haslar Farm (though spelt Hasler Farm at the time) within the liberty of Alverstoke. The site was a slightly unusual location for a hospital because it was surrounded by the Gosport Creek, with no readily available access: such an area was chosen to prevent press-ganged sailors from absconding. Royal Naval Cemetery It was primarily to serve the hospital that the Haslar Royal Naval Cemetery was laid out. It contains (June 2014) Commonw ...

Horsepower
Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower (or imperial horsepower), which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts. The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. The definition of the unit varied among geographical regions. Most countries now use the SI unit watt for measurement of power. With the implementation of the EU Directive 80/181/EEC on 1 January 2010, the use of horsepower in the EU is permitted only as a supplementary unit. History The development of the stea ...
