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, SS ''Great Britain'' in 1843. However, iron hulls could not be sheathed with Muntz metal, copper alloy (due to Galvanic corrosion, 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 ongo ...

Wood
Wood is a structural tissue/material found as xylem in the stems and roots of trees and other woody plants. It is an organic materiala natural composite of cellulosic 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 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 mechanical-support function, enabling woody plants to grow large or to stand up by themselves. It also conveys water and nutrients among 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, woodchips, or fibers. 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 production ...

Port Adelaide is a port-side region of Adelaide, approximately northwest of the Adelaide city centre, Adelaide CBD.

Shipbuilding
Shipbuilding is the construction of ships and other Watercraft, floating vessels. In modern times, 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. Until recently, with the development of complex non-maritime technologies, a ship has often represented the most advanced structure that the society building it could produce. Some key industrial advances were developed to support shipbuilding, for instance the sawing of timbers by Saw#Mechanically powered saws, mechanical saws propelled by windmills in Dutch shipyards during the first half of the 17th century. The design process saw the early adoption of the logarithm (invented in 1615) to generate the curves used to produce the shape of a hull (watercraft), hull, especially when scaling up these curves accurately in the mould Lofting, loft. Shipbuilding and ship repairs, both commercial an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lyttelton Harbour / Whakaraupō
Lyttelton Harbour / Whakaraupō is a major inlet on the northwest side of Banks Peninsula, on the coast of Canterbury, New Zealand; the other major inlet is Akaroa Harbour, which enters from the southern side of the peninsula.

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 Fuzhou 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 Fuzhou, 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.
