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.

Sea Shepherd Conservation Society

The Sea Shepherd Conservation Society (SSCS) is a non-profit, marine conservation organization based in Friday Harbor on San Juan Island, Washington, in the United States.

Sea Shepherd uses direct action tactics to protect marine life. The organization was founded in 1977 under the name Earth Force Society by Paul Watson, a former member of Greenpeace, after a dispute with that organization over what Watson saw as its lack of more aggressive intervention. The group has a strong focus on public relations to spread its message via the media. In 2008, Animal Planet began filming the weekly series Whale Wars based on the group's encounters with the Japanese whaling fleet in the Southern Ocean, a development which brought the group much publicity.

Sea Shepherd currently operates the vessels MY Steve Irwin, the MY Bob Barker, the MY Sam Simon (donated and named after Sam Simon, co-founder of The Simpsons) and the MV Brigitte Bardot. Operations have included scuttling and disabling whaling vessels at harbor, intervening in Canadian and Namibian seal hunts, shining laser light into the eyes of whalers, throwing bottles of foul-smelling butyric acid onto vessels at sea, boarding of whaling vessels while at sea, and seizure and destruction of drift nets at sea. Sea Shepherd claims that their aggressive actions are necessary, as the international community has shown itself unwilling or unable to stop species-endangering whaling and fishing practices.
