HMS Abbotsham
HMS ''Abbotsham'' was one of 93 ships of the ''Ham'' class of inshore minesweepers. Their names were all chosen from villages ending in ''-ham''. The minesweeper was named after Abbotsham in Devon. ''Abbotsham'' was one of the third series of ''Ham''-class minesweepers, with an all-wooden hull, and was built by William Blackmore, completing on 10 January 1957.Gardiner and Chumbley, 1995, p. 541.Worth 1986, p. 123. The ''Ham'' class proved to be too small to carry modern minesweeping gear, and like many of the class, ''Abbotsham'' was quickly placed in operational reserve, entering this state in November 1957. She remained in operational reserve at Rosneath until 1966, when she was placed on the disposal list, the ship being sold in 1967.Worth 1986, p. 125.

Pennant Number
In the Royal Navy and other navies of Europe and the Commonwealth of Nations, ships are identified by pennant number (an internationalisation of ''pendant number'', which it was called before 1948). Historically, naval ships flew a flag that identified a flotilla or type of vessel. For example, the Royal Navy used a red burgee for torpedo boats and a pennant with an H for torpedo boat destroyers. Adding a number to the type-identifying flag uniquely identified each ship. In the current system, a letter prefix, called a ''flag superior'', identifies the type of ship, and numerical suffix, called a flag inferior, uniquely identifies an individual ship. Not all pennant numbers have a flag superior. Royal Navy systems The Royal Navy first used pennants to distinguish its ships in 1661 with a proclamation that all of his majesty's ships must fly a union pennant. This distinction was further strengthened by a proclamation in 1674 which forbade merchant vessels from flying any pennants ...

Ham Class Minesweeper
The Ham class was a class of inshore minesweepers (IMS), known as the Type 1, of the British Royal Navy. The class was designed to operate in the shallow water of rivers and estuaries. All of the ships in the class are named for British place names that end with -"ham". The parent firm that was responsible for supervising construction was Samuel White of Cowes, Isle of Wight. Unlike traditional minesweepers, they were not equipped for sweeping moored or magnetic mines. Their work was to locate individual mines and neutralise them. This was a then-new role, and the class was configured for working in the shallow water of rivers, estuaries and shipping channels. The class consisted of 93 ships, launched between 1954 and 1959. was the first. They were built in three slightly different sub-groups, the first sub-group, the 26-group, is distinguished by pennant numbers 26xx, and the second and third sub-groups, the 27-group, are distinguished by pennant numbers 27xx.

Length Overall
__NOTOC__ Length overall (LOA, o/a, o.a. or oa) is the maximum length of a vessel's hull measured parallel to the waterline. This length is important while docking the ship. It is the most commonly used way of expressing the size of a ship, and is also used for calculating the cost of a marina berth (for example, £2.50 per metre LOA). LOA is usually measured on the hull alone. For sailing ships, this may ''exclude'' the bowsprit and other fittings added to the hull. This is how some racing boats and tall ships use the term LOA. However, other sources may include bowsprits in LOA. Confusingly, LOA has different meanings. "Sparred length", "Total length including bowsprit", "Mooring length" and "LOA including bowsprit" are other expressions that might indicate the full length of a sailing ship. LOD Often used to distinguish between the length of a vessel including projections (e.g. bow sprits, etc.) from the length of the hull itself, the Length on Deck or LOD is often repor ...

Length Between Perpendiculars
Length between perpendiculars (often abbreviated as p/p, p.p., pp, LPP, LBP or Length BPP) is the length of a ship along the summer load line from the forward surface of the stem, or main bow perpendicular member, to the after surface of the sternpost, or main stern perpendicular member. When there is no sternpost, the centerline axis of the rudder stock is used as the aft end of the length between perpendiculars. Measuring to the stern post or rudder stock was believed to give a reasonable idea of the ship's carrying capacity, as it excluded the small, often unusable volume contained in her overhanging ends. On some types of vessels this is, for all practical purposes, a waterline measurement. In a ship with raked stems, naturally that length changes as the draught of the ship changes, therefore it is measured from a defined loaded condition.

Oerlikon 20 Mm Cannon
The Oerlikon 20 mm cannon is a series of autocannons, based on an original German Becker Type M2 20 mm cannon design that appeared very early in World War I. It was widely produced by Oerlikon Contraves and others, with various models employed by both Allied and Axis forces during World War II. Many versions of the cannon are still used today. Blowback-operated models History Origins During World War I, the German industrialist Reinhold Becker developed a 20 mm caliber cannon, known now as the 20 mm Becker using the advanced primer ignition blowback (API blowback) method of operation. This used a 20×70mmRB cartridge and had a cyclic rate of fire of 300 rpm. It was used on a limited scale as an aircraft gun on ''Luftstreitkräfte'' warplanes, and an anti-aircraft gun towards the end of that war. Because the Treaty of Versailles banned further production of such weapons in Germany, the patents and design works were transferred in 1919 to the Swiss firm SEMAG (''Seeba ...

Minesweeper (ship)
A minesweeper is a small warship designed to remove or detonate naval mines. Using various mechanisms intended to counter the threat posed by naval mines, minesweepers keep waterways clear for safe shipping. History The earliest known usage of the naval mine dates to the Ming dynasty.Needham, Volume 5, Part 7, 203–205. Dedicated minesweepers, however, only appeared many centuries later during the Crimean War, where they were deployed by the British. The Crimean War minesweepers were rowboats trailing grapnels to snag mines. Minesweeping technology picked up in the Russo-Japanese War, using aging torpedo boats as minesweepers. In Britain, naval leaders recognized before the outbreak of World War I that the development of sea mines was a threat to the nation's shipping and began efforts to counter the threat. Sir Arthur Wilson noted the real threat of the time was blockade aided by mines and not invasion. The function of the fishing fleet's trawlers with their trawl gear was ...

Rosneath
Rosneath (''Ros Neimhidh'' in Gaelic) is a village in Argyll and Bute, Scotland. It sits on the western shore of the Gare Loch, northwest of the tip of the Rosneath Peninsula. It is about by road from the village of Kilcreggan, which is sited on the southern shore of the peninsula, on the Firth of Clyde. The Gare Loch narrows at Rosneath to under half a mile (around 600 metres) at a place known as the ''Rhu Narrows'', after the village of Rhu on the eastern shore of the loch. Rosneath Bay to the south of the village curves eastward to Castle Point, near the site of the former Roseneath Castle, in the grounds of the former Rosneath House which are now occupied by Rosneath caravan park. The coast turns south past Culwatty Bay to Rosneath Point at the tip of the peninsula, which is directly north of Princes Pier in the large town of Greenock, distant on the southern shore of the Firth.

List Of Ship Names Of The Royal Navy
This is an alphabetical list of the ''names'' of all ships that have been in service with the Royal Navy, or with predecessor fleets formally in the service of the Kingdom of England or the Commonwealth of England. The list also includes fictional vessels which have prominently featured in literature about the Royal Navy. Names are traditionally re-used over the years, and have been carried by more than one ship. Altogether over 13,000 ships have been in service with the Royal Navy.Colledge and Warlow (2006) ''Page viii''. Unlike many other naval services, the Royal Navy designates certain types of shore establishment (e.g. barracks, naval air stations and training establishments) as "ships" and names them accordingly. These establishments are often referred to in service slang as ''stone frigates''. Lists of ship names Due to the large number of names the list has been split into smaller lists: Alphabetical *List of ship names of the Royal Navy (A) *List of ship names o ...
