Introduction to ship

A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying passengers or merchandise, or in support of specialized missions, like defense, research and fishing. traditionally, a "ship" was a sailing ship with a minimum of 3 square-rigged masts and a full bowsprit. Ships are usually distinguished from boats, based on size, shape, load capacity, and tradition.

Ships are necessary contributors to human migration and commerce. they have supported the spread of colonization and also the slave trade, but have additionally served scientific, cultural, and humanitarian needs. after the fifteenth century, new crops that had come from and to the americas via the european seafarers considerably contributed to the planet population growth. Ship transport is responsible for the largest portion of world commerce.

Merchant ships exist to carry cargoes across the waterways of the world safely, speedily and economically. Since a large part of the world' s surface, approximately three-fifths, is covered by water, it is reasonable to consider that the merchant ship will continue to perform its function for many centuries to come. The worldwide nature of this function involves the ship, its cargo and its crew in many aspects of international life. Some features of this international transportation, such as weather and climatic changes, availability of cargo handling facilities and international regulations.

The ship, in its various forms, has evolved to accomplish its function depending upon three main factors-the type of cargo carried, the type of construction and materials used, and the area of operation.
