Careening
Careening (also known as "heaving down") is a method of gaining access to the hull of a sailing vessel without the use of a dry dock. It is used for cleaning or repairing the hull. Before ship's hulls were protected from marine growth by fastening copper sheets over the surface of the hull, fouling by this growth would seriously affect the sailing qualities of a ship, causing a large amount of drag. As this growth was underwater, removing it was difficult. Beaching the vessel at high tide allowed the lower hull to be exposed for cleaning or repairs. Etymology The term, and similar terms in French, Spanish and Italian, derive from the term for a ship's keel—''carène'' (French), ''carena'' (Spanish), ''carena'' (Italian). These come from the Latin term for keel, ''carīna''. Practice The ship was grounded broadside on a steep beach at high tide or, in dockyards, moored at a permanent facility for careening known as a ''careening wharf''. A beach favoured for careening was c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Careening Bay
Coronation Island, also known as Garlinju, is located off the Kimberley coast of Western Australia. It encompasses an area of . It is located off Port Nelson in the Bonaparte Archipelago, as a part of the group of islands known as the Coronation Islands, which were named by Philip Parker King, the first European to visit the islands in 1820, after the anniversary of the coronation of George III, who had died in January of that year. The traditional owners of the area are the Wunambal peoples, in whose language group of Wunambal the name for the island is Garlinju. The area holds preservation status. During the Second World War, a military installation was established for Allied special forces under training purposes, later known as Station XIII; The station housed Allied commando force Z Special Unit for training prior towards the ill-fated Operation Rimau, executed by Lt. Col. Ivan Lyon of the British Army. Allied forces remained within the training station after the disast ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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).

Ship Grounding
Ship grounding or ship stranding is the impact of a ship on seabed or waterway side. It may be intentional, as in beaching (nautical), beaching to land crew or cargo, and careening, for maintenance or repair, or unintentional, as in a marine accident. In accidental cases, it is commonly referred to as "running aground". When unintentional, grounding may result simply in stranding, with or without damage to the submerged part of the ship's hull. Breach of the hull may lead to significant flooding, which in the absence of containment in watertight bulkheads may substantially compromise the ship's structural integrity, stability, and safety. As hazard Severe grounding applies extreme loads upon ship structures. In less severe accidents, it might result only in damage to the hull; however, in most serious accidents, it might lead to hull breaches, cargo spills, total loss of the vessel, and, in the worst cases, human casualties. Grounding accounts for about one-third of commercia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Mahon Dockyard
Port Mahon Dockyard was a Royal Navy Dockyard located at Port Mahon, Menorca, Spain. It was opened in 1708 and in 1802 the port was ceded back to Spain. However a resident commissioner of the Royal Navy was still appointed as late as 1814. The dockyard was administered by the Navy Board and was part of the Mediterranean Fleet. History The Port Mahon Dockyard was established at Port Mahon, one of the world's deepest natural harbours, in 1708, following orders issued by the British Admiralty, Admiralty to Admiral Sir George Byng, 1st Viscount Torrington, George Byng the Commander-in-Chief of the Mediterranean Fleet, Mediterranean Squadron. He was instructed to develop the Port of Mahon as a naval base following the Capture of Minorca (1708), capture of Minorca. The dockyard was located on the north side of the Port Mahon, harbour, opposite Port Mahon town. In 1756 control of the dockyard was fought over during the Battle of Minorca (1756).

Royal Naval Dockyard, Halifax
Royal Naval Dockyard, Halifax was a Royal Navy base in Halifax, Nova Scotia. Established in 1759, the Halifax Yard served as the headquarters for the Royal Navy's North American Station for sixty years, starting with the Seven Years' War. The Royal Navy continued to operate the station until it was closed in 1905. The station was sold to Canada in 1907 becoming His Majesty's Canadian Dockyard, a function it still serves today as part of CFB Halifax. History Halifax Harbour had served as a Royal Navy seasonal base from the founding of the city in 1749, using temporary facilities and a careening beach on Georges Island. The British purchased the property which now contains the Fleet Maintenance Facility Cape Scott for the Naval Yard. This property had belonged to John Gorham (Gorham Point), Captain Ephraim Cook, Philip Durell, Joseph Gerrish and William Nesbitt. (In the summer of 1751, Gorham built the first registered vessel in Halifax, a brig he named ''Osborn Galley ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Biofouling
Biofouling or biological fouling is the accumulation of microorganisms, plants, algae, or small animals where it is not wanted on surfaces such as ship and submarine hulls, devices such as water inlets, pipework, grates, ponds, and rivers that cause degradation to the primary purpose of that item. Such accumulation is referred to as '' epibiosis'' when the host surface is another organism and the relationship is not parasitic. Since biofouling can occur almost anywhere water is present, biofouling poses risks to a wide variety of objects such as boat hulls and equipment, medical devices and membranes, as well as to entire industries, such as paper manufacturing, food processing, underwater construction, and desalination plants. Anti-fouling is the ability of specifically designed materials (such as toxic biocide paints, or non-toxic paints) to remove or prevent biofouling. The buildup of biofouling on marine vessels poses a significant problem. In some instances, the hull str ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Travel Lift
A travel lift or travelift (also called a boat hoist, boat gantry crane, or boat crane) is a specialised type of crane used for lifting boats out of the water and transporting them around Dock (maritime), docks or marina, marinas. These cranes allow boats with Mast (sailing), masts or tall superstructure to be transported around hard stands as the tall upper structure can pass through the open end of the crane framework before lifting and after setting down. Travel lifts typically have two rectangular side frames joined by a Beam (structure), beam across one end. The lift is mobile with four groups of steerable wheels, one at each corner. Boats are typically lifted using straps, slung between the two sides which can be passed under boats when either in the water or on the hard stand. Steel wire cables on winches are used to lift the boat. To remove a boat from the water, two basic methods may be used. In one, the boat is positioned in a narrow dock, or lifting well, with two pa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

HMS Royal George (1756)
HMS ''Royal George'' was a ship of the line of the Royal Navy. A first-rate with 100 guns on three decks, she was the largest warship in the world at the time of her launch on 18 February 1756. Construction at Woolwich Dockyard had taken ten years. The ship saw immediate service during the Seven Years' War, including the Raid on Rochefort in 1757. She was Admiral Sir Edward Hawke's flagship at the Battle of Quiberon Bay in 1759. The ship was laid up following the conclusion of the war in 1763, but was reactivated in 1777 for the American Revolutionary War. She then served as Rear Admiral Robert Digby's flagship at the Battle of Cape St Vincent in 1780. ''Royal George'' sank on 29 August 1782 whilst anchored at Spithead off Portsmouth. The ship was intentionally rolled (a 'parliamentary heel') so maintenance could be performed on the hull, but the roll became unstable and out of control; the ship took on water and sank. More than 800 people died, making it one of the most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Charles Swan (pirate)
Charles Swan (died 1690) was a reluctant buccaneer. Captain Swan was forced into piracy by his crew in the 1680s, and proceeded to write letters to the owners of his ship ''Cygnet'' in London, begging them to intercede with James II of England for his pardoneven as he looted his way up and down the coastal areas of South America. He was present at the attack on Payta in 1684 alongside John Eaton (pirate), John Eaton, where he burned the town after no booty was found. On 25 August 1685, he separated from his confederates Peter Harris (buccaneer), Peter Harris and Edward Davis (buccaneer), Edward Davis, and sailed up the coast of Mexico alongside Francis Townley, but met with little success.
