Ship

A ship is a large buoyant watercraft. Ships are generally distinguished from boats based on size, shape and cargo or passenger capacity. Ships are used on lakes, seas,rivers,and oceans for a variety of activities, such as the transport of people or goods, fishing, entertainment, public safety, and warfare. Historically, a "ship" was a sailing vessel with at least three square-rigged masts and a full bowsprit.

In armed conflict and in daily life, ships have become an integral part of modern commercial and military systems. Fishing boats are used by millions of fishermen throughout the world. Military forces operate vessels for naval warfare and to transport and support forces ashore. Commercial vessels, nearly 35,000 in number, carried 7.4 billion tons of cargo in 2007. As of 2011, there are about 104,304 ships with IMO numbers in the world.

Ships were always a key in history's great explorations and scientific and technological development. Navigators such as Zheng He spread such inventions as the compass and gunpowder. Ships have been used for such purposes as colonization and the slave trade, and have served scientific, cultural, and humanitarian needs. After the 16th century, new crops that had come from and to the Americas via the European seafarers significantly contributed to the world population growth.Ship transport has shaped the world's economy into today's energy-intensive pattern.

Cruise ship

A cruise ship or cruise liner is a passenger ship used for pleasure voyages, where the voyage itself and the ship's amenities are a part of the experience, as well as the different destinations along the way. Transportation is not the prime purpose, as cruise ships operate mostly on routes that return passengers to their originating port, so the ports of call are usually in a specified region of a continent. There are even "cruises to nowhere" or "nowhere voyages" where the ship makes 2–3 night round trips without any ports of call.

By contrast, dedicated transport oriented ocean liners do "line voyages" and typically transport passengers from one point to another, rather than on round trips. Traditionally, an ocean liner for the transoceanic trade will be built to a higher standard than a typical cruise ship, including high freeboard and stronger plating to withstand rough seas and adverse conditions encountered in the open ocean, such as the North Atlantic. Ocean liners also usually have larger capacities for fuel, victuals, and other stores for consumption on long voyages, compared to dedicated cruise ships.

Coast guard

A coast guard or coastguard is a maritime security organization of a particular country. The term implies widely different responsibilities in different countries, from being a heavily armed military force with customs and security duties to being a volunteer organization tasked with search and rescue functions and lacking any law enforcement powers. However, a typical coast guard's functions are distinct from typical functions of both the navy (a pure military force) and a transportation police (a civilian law enforcement agency).

History

The modern Her Majesty's Coastguard of the United Kingdom was established in 1809 as the Waterguard, and was originally devoted to the prevention of smuggling as a department of the HM Customs and Excise authority. It was, however, also responsible for giving assistance to shipwrecks.

Each Water Guard station was issued with Manby's Mortar which was invented by Captain George William Manby in 1808. The mortar fired a shot with a line attached from the shore to the wrecked ship and was used for many years up and down the coastline. This began the process in which the Coastguard assumed a life saving role. In 1821 a committee of inquiry recommended that responsibility for the Preventative Water Guard be transferred to the Board of Customs. The Treasury agreed and in a Minute dated 15 January 1822, directed that the preventative services, which consisted of the Preventative Water Guard, cruisers, and Riding Officers should be placed under the authority of the Board of Customs and in future should be named the Coast Guard. In 1845 the Coastguard was subordinated to the Admiralty.
