Active-class Patrol Boats
The ''Active''-class frigate was a 32-gun fifth-rate frigate class of eight ships designed by Edward Hunt to replace the design, which they resembled with a distinct midsection. Due to poor performance of the ''Active'' class, orders continued for the ''Amazon'' class. Description The ''Active'' class was designed with a gundeck, measuring at the keel, at the beam, and a draught of . They displaced tons burthen. The class was designed with an armament of 26 cannon on the gundeck, four guns on the quarterdeck with four carronades, and two 6 pdr guns and two 24 pdr carronades on the forecastle The forecastle ( ; contracted as fo'c'sle or fo'c's'le) is the upper deck (ship), deck of a sailing ship forward of the foremast, or, historically, the forward part of a ship with the sailors' living quarters.

Thomas Whitcombe
Thomas Whitcombe ( – ) was an English painter who specialised in marine art. Among his work are over 150 actions the Royal Navy participated in during the French Revolutionary and Napoleonic Wars, and he exhibited his works at the Royal Academy, British Institution and Royal Society of British Artists. Whitcombe's pictures are highly sought after today. Life Thomas Whitcombe was born in London between 1752 and 19 May 1763, with the latter date frequently cited. Little is known of his background or training, although speculation based on the locations depicted in his paintings may provide some clues. It is known that he was in Bristol in 1787 and later travelled to the South Coast; there are few ports or harbours from this region that do not feature in his work. In 1789 he toured Wales and in 1813 he travelled to Devon, painting scenes around Plymouth harbour. During his career he also painted scenes showing the Cape of Good Hope, Madeira, Cuba and Cape Horn. Between 1783 and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carronade
A carronade is a short, smoothbore, cast-iron cannon which was used by the Royal Navy. It was first produced by the Carron Company, an ironworks in Falkirk, Scotland, and was used from the last quarter of the 18th century to the mid-19th century. Its main function was to serve as a powerful, short-range, anti-ship and anti-crew weapon. The technology behind the carronade was greater dimensional precision, with the shot fitting more closely in the barrel, thus transmitting more of the propellant charge's energy to the projectile, allowing a lighter gun using less gunpowder to be effective. Carronades were initially found to be very successful, but they eventually disappeared as naval artillery advanced, with the introduction of rifling and consequent change in the shape of the projectile, exploding shells replacing solid shot, and naval engagements being fought at longer ranges. History The carronade was designed as a short-range naval weapon with a low muzzle velocity f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Castle Harbour, Bermuda
Castle Harbour is a large natural harbour in Bermuda. It is located between the northeastern end of the main island and St. David's Island. Originally called ''Southampton Port'', it was renamed as a result of its heavy fortification in the early decades of the Seventeenth century. Geography Castle Harbour is surrounded by St. George's Parish to the north, east, and south, as well as Hamilton Parish to the west. A chain of islands and rocks stretches across the main opening to the Atlantic Ocean, in the east, notably Cooper's Island (which was made a landmass contiguous to St. David's Island and Longbird Island in the 1940s), and Nonsuch Island. The only channel suitable for large vessels to enter the harbour from the open Atlantic is Castle Roads, which was historically guarded by a number of fortifications, on Castle Island, Southampton Island, and Charles Island. Forts were also placed nearby on other small islands, and on the Tucker's Town peninsula of the Main Island. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Forecastle
The forecastle ( ; contracted as fo'c'sle or fo'c's'le) is the upper deck (ship), deck of a sailing ship forward of the foremast, or, historically, the forward part of a ship with the sailors' living quarters. Related to the latter meaning is the phrase "Wiktionary:before the mast, before the mast" which denotes anything related to ordinary sailors, as opposed to a ship's officers. History and design In medieval shipbuilding, a ship of war was usually equipped with a tall, multi-deck castle-like structure in the bow (ship), bow of the ship. It served as a platform for archers to shoot down on enemy ships, or as a defensive stronghold if the ship were boarded. A similar but usually much larger structure, called the aftcastle, was at the aft end of the ship, often stretching all the way from the main Mast (sailing), mast to the stern. Having such tall upper works on the ship was detrimental to sailing performance. As cannons were introduced and gunfire replaced boarding as th ...

Displacement (ship)
The displacement or displacement tonnage of a ship is its weight. As the term indicates, it is measured indirectly, using Archimedes' principle, by first calculating the volume of water displaced by the ship, then converting that value into weight. Traditionally, various measurement rules have been in use, giving various measures in long tons. Today, tonnes are more commonly used. Ship displacement varies by a vessel's degree of load, from its empty weight as designed (known as "lightweight tonnage") to its maximum load. Numerous specific terms are used to describe varying levels of load and trim, detailed below. Ship displacement should not be confused with measurements of volume or capacity typically used for commercial vessels and measured by tonnage: net tonnage and gross tonnage. Calculation The process of determining a vessel's displacement begins with measuring its draft.George, 2005. p. 5. This is accomplished by means of its "draft marks". A merchant vessel has t ...

Draft (hull)
The draft or draught of a ship is a determined depth of the vessel below the waterline, measured vertically to its hull's lowest—its propellers, or keel, or other reference point. Draft varies according to the loaded condition of the ship. A deeper draft means the ship will have greater vertical depth below the waterline. Draft is used in under keel clearance calculations, where the draft is calculated with the available depth of water (from Electronic navigational charts) to ensure the ship can navigate safely, without grounding. Navigators can determine their draught by calculation or by visual observation (of the ship's painted load lines). Related terminology A ship's draft/draught is the "depth of the vessel below the waterline measured vertically to the lowest part of the hull, propellers, or other reference point". That is, the draft or draught is the maximum depth of any part of the vessel, including appendages such as rudders, propellers and drop keels if de ...

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 sides 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 cora ...

Keel
The keel is the bottom-most longitudinal structural element of a watercraft, important for stability. On some sailboats, it may have a fluid dynamics, hydrodynamic and counterbalancing purpose as well. The keel laying, laying of the keel is often the initial step in constructing a ship. In the British and American shipbuilding traditions, this event marks the beginning date of a ship's construction. Etymology The word "keel" comes from Old English language, Old English , Old Norse , = "ship" or "keel". It has the distinction of being regarded by some scholars as the first word in the English language recorded in writing, having been recorded by Gildas in his 6th century Latin work ''De Excidio et Conquestu Britanniae'', under the spelling ''cyulae'' (he was referring to the three ships that the Saxons first arrived in). is the Latin word for "keel" and is the origin of the term careening, careen (to clean a keel and the hull in general, often by rolling the ship on its side).

Frigate
A frigate () is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied. The name frigate in the 17th to early 18th centuries was given to any full-rigged ship built for speed and maneuverability, intended to be used in scouting, escort and patrol roles. The term was applied loosely to ships varying greatly in design. In the second quarter of the 18th century, what is now generally regarded as the 'true frigate' was developed in France. This type of vessel was characterised by possessing only one armed deck, with an unarmed deck below it used for berthing the crew. Late in the 19th century (British and French prototypes were constructed in 1858), a type of powerful ironclad warships was developed, and because they had a single gun deck, the term 'frigate' was used to describe them. Later developments in ironclad ships rendered the 'frigate' designation obsolete and the term fell out of favour. During the Second World War ...

Quarterdeck
The quarterdeck is a raised deck behind the main mast of a sailing ship. Traditionally it was where the captain commanded his vessel and where the ship's colours were kept. This led to its use as the main ceremonial and reception area on board, and the word is still used to refer to such an area on a ship or even in naval establishments on land. Many such facilities have areas decorated like shipboard quarterdecks. In the 20th century the word came to be applied to the area at the stern of the ship, often (on naval vessels) used for secondary weapons and (on battleships) seaplane catapults. Ceremonial use There are ancient traditions of offering special deference to the quarterdeck. Greek, Roman, and Carthaginian warships all carried shrines which were given special respect. This continued into Christian times, and in medieval British warships, the religious shrine was set up on the quarterdeck. All hands were required to salute it by taking off their hats or caps.

Liverpool
Liverpool is a port City status in the United Kingdom, city and metropolitan borough in Merseyside, England. It is situated on the eastern side of the River Mersey, Mersey Estuary, near the Irish Sea, north-west of London. With a population of (in ), Liverpool is the administrative, cultural and economic centre of the Liverpool City Region, a combined authority, combined authority area with a population of over 1.5 million. Established as a borough in Lancashire in 1207, Liverpool became significant in the late 17th century when the Port of Liverpool was heavily involved in the Atlantic slave trade. The port also imported cotton for the Textile manufacture during the British Industrial Revolution, Lancashire textile mills, and became a major departure point for English and Irish emigrants to North America. Liverpool rose to global economic importance at the forefront of the Industrial Revolution in the 19th century and was home to the Liverpool and Manchester Railway, firs ...
