Ship

Ship

A ship is a large watercraft that travels the world's oceans and other sufficiently deep waterways, carrying passengers or goods, or in support of specialized missions, such as defense, research, and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity, and tradition.

History

Ships have been important contributors to human migration and commerce. They have supported the spread of colonization and the slave trade, but have also served scientific, cultural, and humanitarian needs. After the 15th century, new inventions such as the Sternpost rudder, Magnetic compass, and Astrolabe led to ships being further improved and developed.

Types of Ships

There are various types of ships, which can be categorized by their use, by their propulsion, or by their construction.

By Use

• Cargo ship: A type of ship that carries cargo, goods, and materials from one port to another.
• Passenger ship: A ship whose primary function is to carry passengers.
• Fishing vessel: A ship or boat used to catch fish in the sea, or on a lake or river.

By Propulsion

• Sailing ship: A ship propelled by means of sails.
• Steamship: A ship that is propelled primarily by steam power, typically driving propellers or paddlewheels.
• Motor ship: A ship propelled by an internal combustion engine or an electric motor.

By Construction

• Wooden ship: A ship made primarily of wood.
• Steel ship: A ship made primarily of steel.
• Fiberglass ship: A ship made primarily of fiberglass.

Design and Construction

The design and construction of ships is based on the science of naval architecture and marine engineering. It involves knowledge of fluid dynamics, material science, and the mechanics of structures, among other disciplines.
