Screw Frigate
Steam frigates (including screw frigates) and the smaller steam corvettes, steam sloops, steam gunboats and steam schooners, were steam-powered warships that were not meant to stand in the line of battle. There were some exceptions like for example the France, French Napoléon-class ship of the line, Napoléon class steam ship of the line was meant to stand in the line of battle, making it the world's first steam battleship. The first such ships were paddle steamers. Later on the invention of Propeller#Screw propeller, screw propulsion enabled construction of steam-powered versions of the traditional ship of the line, ships of the line, frigates, corvettes, Sloop-of-war, sloops and gunboats. Evolution First steam warships The first small vessel that can be considered a steam warship was the ''Demologos'', which was launched in 1815 for the United States Navy. From the early 1820s, the British Navy began building a number of small Steamship, steam warships including the armed tu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sloop-of-war
In the 18th century and most of the 19th, a sloop-of-war in the Royal Navy was a warship with a single gun deck that carried up to eighteen guns. The rating system covered all vessels with 20 guns and above; thus, the term ''sloop-of-war'' encompassed all the unrated combat vessels, including the very small gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fireships were classed as sloops-of-war, and in practice these were employed in the sloop role when not carrying out their specialised functions. In World War I and World War II, the Royal Navy reused the term "sloop" for specialised convoy-defence vessels, including the of World War I and the highly successful of World War II, with anti-aircraft and anti-submarine capability. They performed similar duties to the American destroyer escort class ships, and also performed similar duties to the smaller corvettes of the Royal Navy. Rigging A sloop-of-war was quite different from a civilian ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ML 8-inch Shell Gun
The ML 8 inch shell guns of 50 cwt, 54 cwt and 65 cwt were the three variants of British cast iron smoothbore muzzle-loading guns designed specifically to fire the new generation of exploding shells pioneered in the early-mid nineteenth century by Henri-Joseph Paixhans. Design The idea behind a gun that could fire spherical exploding shells but not solid armour-piercing shot was that large projectiles capable of carrying a large explosive filling could be fired from comparatively light guns: the 8-inch 68 pounder gun intended to fire solid shot weighed 95 cwt (4,826 kg) compared to the 65 cwt (3,302 kg) of the typical 8-inch shell gun. This was a "chambered" gun, meaning that the area at the breech-end of the gun where the gunpowder propellant charge burned was not of the same cylindrical section as the gun bore itself. The chamber was of the "Gomer" conical pattern, tapering towards the rear, typical of mortars of the day. This was necessitated by the need to minimise ...

Broadside (naval)
A broadside is the side of a ship, or more specifically the battery of cannon on one side of a warship or their coordinated fire in naval warfare, or a measurement of a warship's maximum simultaneous firepower which can be delivered upon a single target (because this concentration is usually obtained by firing a broadside). From the 16th century until the early decades of the steamship, vessels had rows of guns set in each side of the hull. Firing all guns on one side of the ship became known as a "broadside". The cannon of 18th-century men of war were accurate only at short range, and their penetrating power mediocre, which meant that the thick hulls of wooden ships could only be pierced at short ranges. These wooden ships sailed closer and closer towards each other until cannon fire would be effective. Each tried to be the first to fire a broadside, often giving one party a decisive headstart in the battle when it crippled the other ship.Platt (1993) p. 18 History Since anci ...

Sail Plan
A sail plan is a description of the specific ways that a sailing craft is rigged. Also, the term "sail plan" is a graphic depiction of the arrangement of the sails for a given sailing craft.> In the English language, ships were usually described, until the end of the eighteenth century, in terms of their type of hull design. Using the type of rig as the main type identifer for a vessel only became common in the nineteenth century. This is illustrated by the terminology for ships in the large fleet of colliers that traded to London from the coal ports of the Northeast of England (of which was a well-known example). Many of these full-rigged ships (square rigged on all of three masts) had the hull type "bark"another common classification was "cat". In the second half of the eighteenth century, the square sails on the mizzen were often eliminated. The resulting rig acquired the name of the hull type: initially as "bark" and soon as "barque". This explains the Royal Navy's descripti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paddle Steamer
A paddle steamer is a steamship or steamboat powered by a steam engine that drives paddle wheels to propel the craft through the water. In antiquity, paddle wheelers followed the development of poles, oars and sails, where the first uses were wheelers driven by animals or humans. In the early 19th century, paddle wheels were the predominant way of propulsion for steam-powered boats. In the late 19th century, paddle propulsion was largely superseded by the screw propeller and other marine propulsion systems that have a higher efficiency, especially in rough or open water. Paddle wheels continue to be used by small, pedal-powered paddle boats and by some ships that operate tourist voyages. The latter are often powered by diesel engines. Paddle wheels The paddle wheel is a large steel framework wheel. The outer edge of the wheel is fitted with numerous, regularly spaced paddle blades (called floats or buckets). The bottom quarter or so of the wheel travels under water. An e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Constance (1846)
HMS ''Constance'' was a 50-gun fourth-rate frigate of the Royal Navy launched in 1846. She had a tonnage of 2,132 and was designed with a V-shaped hull by William Symonds, Sir William Symonds.Mariner's pp 64–68 She was also one of the last class of frigates designed by him.Brock p26 On her shakedown voyage from England to Valparaiso she rounded Cape Horn in good trim, her captain for this voyage being Baldwin Wake Walker, Sir Baldwin Wake Walker, who commented "I think her a good sea boat, and a fine man of war". On the voyage she encountered a hurricane at 62° south. Walker wrote that "nothing could have exceeded the way she went over it, not even straining a rope yarn".Sharp p698 In August 1848 her captain George William Courtenay, for whom the town of Courtenay, British Columbia, Courtenay was named,Akrigg p54 led 250 sailors and marines from Fort Victoria (British Columbia), Fort Victoria to try to intimidate the Indians.Gough p46 In 1848 she became the first Royal Naval ...

Fore-and-aft Rig
A fore-and-aft rig is a sailing vessel rigged mainly with sails set along the line of the keel, rather than perpendicular to it as on a square rigged vessel. Description Fore-and-aft rigged sails include staysails, Bermuda rigged sails, gaff rigged sails, gaff sails, gunter rig, lateen sails, lug sails, tanja sails, the spanker sail on a square rig and crab claw sails. Fore-and-aft rigs include: * Rigs with one mast: the proa, the catboat, the sloop, the cutter * Rigs with two masts: the ketch, the yawl * Rigs with two or more masts: the schooner Barques and barquentines are partially square rigged and partially fore-and-aft rigged. A rig which combines both on a foremast is known as a hermaphroditic rig. History Austronesia The fore-and-aft rig is believed to have been first developed independently by the Austronesian peoples some time around 1500 BC with the invention of the crab claw sail. It is suggested that it evolved from a more primitive "V"-shaped "square" s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Square Rig
Square rig is a generic type of sail and rigging arrangement in which the primary driving sails are carried on horizontal spars which are perpendicular, or square, to the keel of the vessel and to the masts. These spars are called ''yards'' and their tips, outside the lifts, are called the ''yardarms.'' A ship mainly rigged so is called a square-rigger. The square rig is aerodynamically the most efficient running rig (i.e., sailing downwind), and stayed popular on ocean-going sailing ships until the end of the Age of Sail. The last commercial sailing ships, windjammers, were usually square-rigged four-masted barques. History The oldest archaeological evidence of use of a square-rig on a vessel is an image on a clay disk from Mesopotamia from 5000 BC. Single sail square rigs were used by the ancient Egyptians, the Phoenicians, the Greeks, the Romans, and the Celts. Later the Scandinavians, the Germanic peoples, and the Slavs adopted the single square-rigged sail, with it be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Frank Abney Hastings
Frank Abney Hastings ( el, Φραγκίσκος Άστιγξ) (14 February 1794 – 1 June 1828) was a British naval officer and Philhellene. Born to a noble British family, he served in the Royal Navy, seeing action at the Battle of Trafalgar and the Battle of New Orleans. In 1819 he was discharged from the Royal Navy, and a few years later would travel to Greece to aid the Greeks in their struggle for independence, where he would take part in multiple battles, most notably the Battle of Itea, during which his ship the '' Karteria,'' would become the first steam-powered warship to see combat. Early life and career He was the son of Sir Charles Hastings of Willesley Hall, a natural son of Francis Hastings, 10th Earl of Huntingdon. He entered the British Navy in 1805, and was in the Neptune (100) at the Battle of Trafalgar. He also took part in the Battle of New Orleans; but in 1819 a quarrel with his flag captain led to his leaving the service. The revolutionary troubles ...

Greek War Of Independence
The Greek War of Independence, also known as the Greek Revolution or the Greek Revolution of 1821, was a successful war of independence by Greek revolutionaries against the Ottoman Empire between 1821 and 1829. The Greeks were later assisted by the British Empire, Bourbon Restoration in France, Kingdom of France, and the Russian Empire, while the Ottomans were aided by their North African vassals, particularly the eyalet of Egypt Eyalet, Egypt. The war led to the formation of modern Greece. The revolution is Celebration of the Greek Revolution, celebrated by Greeks around the world as Greek Independence Day, independence day on 25 March. Greece, with the exception of the Ionian Islands, came under Ottoman rule in the 15th century, in the decades before and after the fall of Constantinople. During the following centuries, there were sporadic but unsuccessful Ottoman Greece#Uprisings before 1821, Greek uprisings against Ottoman rule. In 1814, a secret organization called Filiki Et ...
