British English
In British English, a dock is an enclosed area of water used for loading, unloading, building or repairing ships. Such a dock may be created by building enclosing harbour walls into an existing natural water space, or by excavation within what would otherwise be dry land.
There are specific types of dock structure where the water level is controlled:
- A wet dock or impounded dock is a variant in which the water is impounded either by dock gates or by a lock, thus allowing ships to remain afloat at low tide in places with high tidal ranges. The level of water in the dock is maintained despite the raising and lowering of the tide. This makes transfer of cargo easier. It works like a lock which controls the water level and allows passage of ships. The world's first enclosed wet dock with lock gates to maintain a constant water level irrespective of tidal conditions was the Howland Great Dock on the River Thames, built in 1703. The dock was merely a haven surrounded by trees, with no unloading facilities. The world's first commercial enclosed wet dock, with quays and unloading warehouses, was the Old Dock at Liverpool, built in 1715 and held up to 100 ships. The dock reduced ship waiting giving quick turn arounds, greatly improving the throughput of cargo.
- A drydock is another variant, also with dock gates, which can be emptied of water to allow investigation and maintenance of the underwater parts of ships.
A dockyard (or "shipyard") consists of one or more docks, usually with other structures.

Famous quotes containing the words british and/or english:
“The great British Library—an immense collection of volumes of all ages and languages, many of which are now forgotten, and most of which are seldom read: one of these sequestered pools of obsolete literature to which modern authors repair, and draw buckets full of classic lore, or “pure English, undefiled” wherewith to swell their own scanty rills of thought.”
—Washington Irving (1783–1859)
“He is no mystic, either, more than Newton or Arkwright or Davy, and tolerates none. Not one obscure line, or half line, did he ever write. His meaning lies plain as the daylight.... It has the distinctness of picture to his mind, and he tells us only what he sees printed in largest English type upon the face of things.”
—Henry David Thoreau (1817–1862)
