HMS Hector (1862)
HMS ''Hector'' was the lead ship of the armoured frigates ordered by the Royal Navy in 1861. Upon completion in 1864, she was assigned to the Channel Fleet. The ship was paid off in 1867 to refit and be re-armed. Upon recommissioning in 1868, she was assigned as the guard ship of the Fleet Reserve in the southern district until 1886. She usually served as Queen Victoria's guard ship when the sovereign was resident at her vacation home on the Isle of Wight. ''Hector'' was paid off in 1886 and hulked in 1900 as a storage ship before being sold for scrap in 1905. Design and description The ''Hector''-class ironclads,Ironclad is the all-encompassing term for armored warships of this period. Armoured frigates were basically designed for the same role as traditional wooden frigates, but this later changed as the size and expense of these ships forced them to be used in the line of battle. like their immediate predecessors, the , were designed as smaller and cheaper versions of the ...

Brassey's Naval Annual
''The Naval Annual'' was a periodical that provided considerable text and graphic information (largely concerning the British Royal Navy) which had previously been obtainable only by consulting a wide range of often foreign language publications. During its life it underwent a number of title changes. The ''Annual'' was started by Thomas Brassey, 1st Earl Brassey, in 1886. Though often compared with '' Jane's Fighting Ships'', the two British annuals were, in fact quite different. The Brassey series began a dozen years earlier, and its special strength was the dozen or more detailed articles on naval (plus, from 1920 through 1935, merchant marine) matters, authored by experts. They covered British and other nations' naval developments ranging from the latest ships to overall policy. The first five or six Brassey volumes used a second printing colour (a light blue green) to highlight armored portions of naval vessels' hulls. Through 1949, the series was also known for its ...

Bulkhead (partition)
A bulkhead is an upright wall within the hull of a ship or within the fuselage of an airplane. Other kinds of partition elements within a ship are decks and deckheads. Etymology The word ''bulki'' meant "cargo" in Old Norse. During the 15th century sailors and builders in Europe realized that walls within a vessel would prevent cargo from shifting during passage. In shipbuilding, any vertical panel was called a head. So walls installed abeam (side-to-side) in a vessel's hull were called "bulkheads". Now, the term bulkhead applies to every vertical panel aboard a ship, except for the hull itself. History Bulkhead partitions are considered to have been a feature of Chinese junks, a type of ship. Song Dynasty author Zhu Yu (fl. 12th century) wrote in his book of 1119 that the hulls of Chinese ships had a bulkhead build. The 5th-century book ''Garden of Strange Things'' by Liu Jingshu mentioned that a ship could allow water to enter the bottom without sinking. Archaeolo ...

Engine Room
On a ship, the engine room (ER) is the compartment where the machinery for marine propulsion is located. To increase a vessel's safety and chances of surviving damage, the machinery necessary for the ship's operation may be segregated into various spaces. The engine room is generally the largest physical compartment of the machinery space. It houses the vessel's prime mover, usually some variations of a heat engine (steam engine, diesel engine, gas or steam turbine). On some ships, there may be more than one engine room, such as forward and aft, or port or starboard engine rooms, or may be simply numbered. The engine room is usually located near the bottom, at the rear or aft end of the vessel, and comprises few compartments. This design maximizes the cargo carrying capacity of the vessel and situates the prime mover close to the propeller, minimizing equipment cost and problems posed from long shaft lines. On some ships, the engine room may be situated mid-ship, such as on v ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Double Bottom
A double hull is a ship hull design and construction method where the bottom and sides of the ship have two complete layers of watertight hull surface: one outer layer forming the normal hull of the ship, and a second inner hull which is some distance inboard, typically by a few feet, which forms a redundant barrier to seawater in case the outer hull is damaged and leaks. The space between the two hulls is sometimes used for storage of ballast water. Double hulls are a more extensive safety measure than double bottoms, which have two hull layers only in the bottom of the ship but not the sides. In low-energy collisions, double hulls can prevent flooding beyond the penetrated compartment. In high-energy collisions, however, the distance to the inner hull is not sufficient and the inner compartment is penetrated as well. Double hulls or double bottoms have been required in all passenger ships for decades as part of the Safety Of Life At Sea or SOLAS Convention. Uses Double hulls ...

Draft (hull)
The draft or draught of a ship's hull is the vertical distance between the waterline and the bottom of the hull ( keel). The draught of the vessel is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if deployed. Draft determines the minimum depth of water a ship or boat can safely navigate. The related term air draft is the maximum height of any part of the vessel above the water. The more heavily a vessel is loaded, the deeper it sinks into the water, and the greater its draft. After construction, the shipyard creates a table showing how much water the vessel displaces based on its draft and the density of the water (salt or fresh). The draft can also be used to determine the weight of cargo on board by calculating the total displacement of water, accounting for the content of the ship's bunkers, and using Archimedes' principle. The closely related term "trim" is defined as the difference between the forward and a ... [...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 In watercraft, a racing shell (also referred to as just a ''fine boat'' (UK) or just ' ...

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 A sternpost is the upright structural member or post at the stern of a (generally wooden) ship or a boat, to which are attached the transoms and the rearmost left corner part of the stern. The sternpost may either be completely vertical or m ..., 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, natural ...

Hulk (ship)
A hulk is a ship that is afloat, but incapable of going to sea. Hulk may be used to describe a ship that has been launched but not completed, an abandoned wreck or shell, or to refer to an old ship that has had its rigging or internal equipment removed, retaining only its buoyant qualities. The word hulk also may be used as a verb: a ship is "hulked" to convert it to a hulk. The verb was also applied to crews of Royal Navy ships in dock, who were sent to the receiving ship for accommodation, or "hulked". Hulks have a variety of uses such as housing, prisons, salvage pontoons, gambling sites, naval training, or cargo storage. In the days of sail, many hulls served longer as hulks than they did as functional ships. Wooden ships were often hulked when the hull structure became too old and weak to withstand the stresses of sailing. More recently, ships have been hulked when they become obsolete or when they become uneconomical to operate. Sheer hulk A sheer hulk (or shear hulk) wa ...

Victoria Of The United Kingdom
Victoria (Alexandrina Victoria; 24 May 1819 – 22 January 1901) was Queen of the United Kingdom of Great Britain and Ireland from 20 June 1837 until her death in 1901. Her reign of 63 years and 216 days was longer than that of any previous British monarch and is known as the Victorian era. It was a period of industrial, political, scientific, and military change within the United Kingdom, and was marked by a great expansion of the British Empire. In 1876, the British Parliament voted to grant her the additional title of Empress of India. Victoria was the daughter of Prince Edward, Duke of Kent and Strathearn (the fourth son of King George III), and Princess Victoria of Saxe-Coburg-Saalfeld. After the deaths of her father and grandfather in 1820, she was raised under close supervision by her mother and her comptroller, John Conroy. She inherited the throne aged 18 after her father's three elder brothers died without surviving legitimate issue. Victoria, a constituti ...

Guard Ship
A guard ship is a warship assigned as a stationary guard in a port or harbour, as opposed to a coastal patrol boat, which serves its protective role at sea. Royal Navy In the Royal Navy of the eighteenth century, peacetime guard ships were usually third-rate or fourth-rate ships of the line. The larger ships in the fleet would be laid up "in ordinary" with skeleton crews, the spars, sails and rigging removed and the decks covered by canvas – the historic equivalent of a reserve fleet. By contrast the guard ships would carry sails and rigging aboard, be defouled below the waterline to increase their speed under sail, and be manned by at least one quarter of their normal crew. A port or major waterway may be assigned a single guardship which would also serve as the naval headquarters for the area. Multiple guardships were required at larger ports and Royal Dockyards, with the largest single vessel routinely serving as the Port Admiral's flagship. If war was declared, or an e ...

Ship Commissioning
Ship commissioning is the act or ceremony of placing a ship in active service and may be regarded as a particular application of the general concepts and practices of project commissioning. The term is most commonly applied to placing a warship in active duty with its country's military forces. The ceremonies involved are often rooted in centuries-old naval tradition. Ship naming and launching endow a ship hull with her identity, but many milestones remain before she is completed and considered ready to be designated a commissioned ship. The engineering plant, weapon and electronic systems, galley, and other equipment required to transform the new hull into an operating and habitable warship are installed and tested. The prospective commanding officer, ship's officers, the petty officers, and seamen who will form the crew report for training and familiarization with their new ship. Before commissioning, the new ship undergoes sea trials to identify any deficiencies needing c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
