Composite Ship
The technique of composite ship construction (wooden planking over a wrought iron frame) emerged in the mid-19th century as the final stage in the evolution of fast commercial sailing ships. Construction of wrought iron hulled vessels had begun in the 1820s and was a mature technology by the time of the launch of the SS ''Great Britain'' in 1843. However, iron hulls could not be sheathed with copper alloy (due to bimetallic corrosion) and so would become festooned with drag-inducing weed during long voyages in the tropics. The wooden planking of a composite ship allowed the copper sheathing essential for fast ocean crossings under sail while the iron frame made the ship relatively immune from hogging and sagging, and took up less interior space than wooden framing. The brief reign of composite clippers as the fastest mode of transport between Europe and Asia was brought to a close by the opening of the Suez Canal in 1869 and ongoing improvement in the performance of steam ship ...

Wood
Wood is a porous and fibrous structural tissue found in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression. Wood is sometimes defined as only the secondary xylem in the stems of trees, or it is defined more broadly to include the same type of tissue elsewhere such as in the roots of trees or shrubs. In a living tree it performs a support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients between the leaves, other growing tissues, and the roots. Wood may also refer to other plant materials with comparable properties, and to material engineered from wood, or woodchips or fiber. Wood has been used for thousands of years for fuel, as a construction material, for making tools and weapons, furniture and paper. More recently it emerged as a feedstock for the productio ...

Port Adelaide
Port Adelaide is a port-side region of Adelaide, approximately northwest of the Adelaide CBD. It is also the namesake of the City of Port Adelaide Enfield council, a suburb, a federal and state electoral division and is the main port for the city of Adelaide. Port Adelaide played an important role in the formative decades of Adelaide and South Australia, with the port being early Adelaide's main supply and information link to the rest of the world. Its Kaurna name, although not officially adopted as a dual name, is Yartapuulti. History Prior to European settlement Port Adelaide was covered with mangrove swamps and tidal mud flats, and lay next to a narrow creek. At this time, it was inhabited by the Kaurna people, who occupied the Adelaide Plains, the Barossa Valley, the western side of the Fleurieu Peninsula, and northwards past Snowtown. The Kaurna people called the Port Adelaide area Yartapuulti, and the whole estuarine area of the Port River ''Yertabulti'' (''Yerta B ...

Shipbuilding
Shipbuilding is the construction of ships and other floating vessels. It normally takes place in a specialized facility known as a shipyard. Shipbuilders, also called shipwrights, follow a specialized occupation that traces its roots to before recorded history. Shipbuilding and ship repairs, both commercial and military, are referred to as "naval engineering". The construction of boats is a similar activity called boat building. The dismantling of ships is called ship breaking. History Pre-history The earliest known depictions (including paintings and models) of shallow-water sailing boats is from the 6th to 5th millennium BC of the Ubaid period of Mesopotamia. They were made from bundled reeds coated in bitumen and had bipod masts. They sailed in shallow coastal waters of the Persian Gulf. 4th millennium BC Ancient Egypt Evidence from Ancient Egypt shows that the early Egyptians knew how to assemble planks of wood into a ship hull as early as 3100 BC.

Lyttelton Harbour / Whakaraupō
Lyttelton Harbour / Whakaraupō is one of two major inlets in Banks Peninsula, on the coast of Canterbury, New Zealand; the other is Akaroa Harbour on the southern coast. It enters from the northern coast of the peninsula, heading in a predominantly westerly direction for approximately from its mouth to the aptly-named Head of the Bay near Teddington. The harbour sits in an eroded caldera of the ancient Banks Peninsula Volcano, the steep sides of which form the Port Hills on its northern shore. The harbour's main population centre is Lyttelton, which serves the main port to the nearby city of Christchurch, linked with Christchurch by the single-track Lyttelton rail tunnel (opened 1867), a two lane road tunnel (opened 1964) and two roads over the Port Hills. Diamond Harbour lies to the south and the Māori village of Rāpaki to the west. At the head of the harbour is the settlement of Governors Bay.

Chatham, Medway
Chatham ( ) is a town located within the Medway unitary authority in the ceremonial county of Kent, England. The town forms a conurbation with neighbouring towns Gillingham, Rochester, Strood and Rainham. The town developed around Chatham Dockyard and several Army barracks, together with 19th-century forts which provided a defensive shield for the dockyard. The Corps of Royal Engineers is still based in Chatham at Brompton Barracks. The Dockyard closed in 1984, but the remaining major naval buildings are an attraction for a flourishing tourist industry. Following closure, part of the site was developed as a commercial port, other parts were redeveloped for business and residential use, and part was used as the Chatham Historic Dockyard museum. Its attractions include the submarine . The town has important road links and the railway and bus stations are the main interchanges for the area. It is the administrative headquarters of Medway unitary authority, as well as its p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sloop
A sloop is a sailboat with a single mast typically having only one headsail in front of the mast and one mainsail aft of (behind) the mast. Such an arrangement is called a fore-and-aft rig, and can be rigged as a Bermuda rig with triangular sails fore and aft, or as a gaff-rig with triangular foresail(s) and a gaff rigged mainsail. Sailboats can be classified according to type of rig, and so a sailboat may be a sloop, catboat, cutter, ketch, yawl, or schooner. A sloop usually has only one headsail, although an exception is the Friendship sloop, which is usually gaff-rigged with a bowsprit and multiple headsails. If the vessel has two or more headsails, the term cutter may be used, especially if the mast is stepped further towards the back of the boat. When going before the wind, a sloop may carry a square-rigged topsail which will be hung from a topsail yard and be supported from below by a crossjack. This sail often has a large hollow foot, and this foot is sometimes fil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
HMS Gannet (1878)
HMS ''Gannet'' is a Royal Navy screw sloop-of-war launched on 31 August 1878. She became a training ship in the Thames in 1903, and was then loaned as a training ship for boys in the Hamble from 1913. She was restored in 1987 and is now part of the UK's National Historic Fleet. Design The ''Doterel'' class were a development of the Osprey class sloop, ''Osprey''-class sloops and were of composite construction, with wooden hulls over an iron frame.

Ambassador (clipper)
''Ambassador'' is a United Kingdom tea clipper built in 1869. She was a composite clipper, built with wooden planking over an iron skeleton and was W. Lund & Co's first tea clipper. She is now a beached wreck in southern Chile. History William Walker built ''Ambassador'' at Lavender Dry Dock in London. Though considered a fast ship, ''Ambassador'' was said to be "very cranky and overmasted". Her first passage to the UK from Foochow came during the Tea Race of 1870 under Captain Duggan and took 115 days, a mediocre performance; that same year the fastest tea passage, also from Foochow, was made by the clipper in just 98 days. ''Ambassador''s fastest passage between China and England was 108 days, in 1872. ''Ambassador'' has been beached at Estancia San Gregorio, Chile since 1899. In 1973 Chile declared her a historic monument. The wreck is now reduced to a skeletal frame.

England
England is a country that is part of the United Kingdom. It shares land borders with Wales to its west and Scotland to its north. The Irish Sea lies northwest and the Celtic Sea to the southwest. It is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain, which lies in the North Atlantic, and includes over 100 smaller islands, such as the Isles of Scilly and the Isle of Wight. The area now called England was first inhabited by modern humans during the Upper Paleolithic period, but takes its name from the Angles, a Germanic tribe deriving its name from the Anglia peninsula, who settled during the 5th and 6th centuries. England became a unified state in the 10th century and has had a significant cultural and legal impact on the wider world since the Age of Discovery, which began during the 15th century.

Greenwich
Greenwich ( , ,) is a town in south-east London, England, within the ceremonial county of Greater London. It is situated east-southeast of Charing Cross. Greenwich is notable for its maritime history and for giving its name to the Greenwich Meridian (0° longitude) and Greenwich Mean Time. The town became the site of a royal palace, the Palace of Placentia from the 15th century, and was the birthplace of many Tudors, including Henry VIII and Elizabeth I. The palace fell into disrepair during the English Civil War and was demolished to be replaced by the Royal Naval Hospital for Sailors, designed by Sir Christopher Wren and his assistant Nicholas Hawksmoor. These buildings became the Royal Naval College in 1873, and they remained a military education establishment until 1998 when they passed into the hands of the Greenwich Foundation. The historic rooms within these buildings remain open to the public; other buildings are used by University of Greenwich and Trinity Laban C ...
