Wharf. A wharf, quay, staith, or staithe is a structure on the shore of a harbour or on the bank of a river or canal where ships may dock to load and unload cargo or passengers. Such a structure includes one or more berths, and may also include piers, warehouses, or other facilities necessary for handling the ships. Wharves are often considered to be a series of docks at which boats are stationed. A marginal wharf is connected to the shore along its full length. Traffic sign: Quayside or river bank ahead. Unprotected quayside or riverbank. A wharf commonly comprises a fixed platform, often on pilings. Commercial ports may have warehouses that serve as interim storage: where it is sufficient a single wharf with a single berth constructed along the land adjacent to the water is normally used; where there is a need for more capacity multiple wharves, or perhaps a single large wharf with multiple berths, will instead be constructed, sometimes projecting over the water. A pier, raised over the water rather than within it, is commonly used for cases where the weight or volume of cargos will be low. Smaller and more modern wharves are sometimes built on flotation devices to keep them at the same level as the ship, even during changing tides. In everyday parlance the term quay is common in the United Kingdom, Canada, Australia, and many other Commonwealth countries, and the Republic of Ireland, and may also refer to neighbourhoods and roadways running along the wayside. The term wharf is more common in the United States. In some contexts wharf and quay may be used to mean pier, berth, or jetty. In old ports such as London many old wharves have been converted to residential or office use. Certain early railways in England referred to goods loading points as wharves. The term was carried over from marine usage. The person who was resident in charge of the wharf was referred to as a wharfinger. Quay in Dublin, Ireland. Originally, werf or werva in Old Dutch simply referred to inhabited ground that was not yet built on, or alternatively to a terp. This could explain the name Ministry Wharf located at Saunderton, just outside High Wycombe, which is nowhere near any body of water. In support of this explanation is the fact that many places in England with wharf in their names are in areas with a high Dutch influence, for example the Norfolk broads. Staith In the northeast and east of England the term staith or staithe is also used. The two terms have historically had a geographical distinction: those to the north in the Kingdom of Northumbria used the Old English spelling staith, southern sites of the Danelaw took the Danish spelling staithe. Both originally referred to jetties or wharves. In time, the northern coalfields of Northumbria developed coal staiths specifically for loading coal onto ships and these would adopt the staith spelling as a distinction from simple wharves: for example, Dunston Staiths in Gateshead and Brancaster Staithe in Norfolk. However, the term staith may also be used to refer only to loading chutes or ramps used for bulk commodities like coal in loading ships and barges. Quay Quay, on the other hand, has its origin in the Proto-Celtic language.
