A ship is any large watercraft. Ships are generally distinguished from boats by their capacity (passengers or goods). They are (normally) swimming unlike floating submarines and hovercrafts. Ships have an organized crew with different functions and command levels, while boats have a maximum of a leader (coxswain, steering man).

Another approach is that if one watercraft can carry another one, the bigger one is called a ship.

There are some exceptions for historical reasons. Watercrafts operating normally on lakes, rivers or other protected water areas are called boats even if they are nowadays big enough to carry themself.

Also, even smaller sailing boats designed for 2 or 3 persons are carrying today a dinghy for life saving purposes or passenger transport outside of ports.

It is a traditional (British) practice to call a ship a "she" or as "her", even if she is named after a man.

General Description

A ship is a large watercraft that is specifically designed for navigation in the maritime context. Ships are typically distinguished from boats based on size, shape, and purpose. They are essential for transporting goods, people, and vehicles across the seas and oceans. Ships come in various types and sizes, ranging from small fishing vessels to massive container ships and oil tankers.

Ships are powered by engines, sails, or a combination of both, depending on the vessel's design and intended use. They can be used for various purposes such as commerce, transportation, fishing, research, and military operations. Ships are equipped with navigation and safety equipment to ensure smooth and safe operations at sea.

Ships have a hull, which is the main structural element of the vessel that provides buoyancy and helps it to float. The hull is typically made of steel or aluminum and is designed to withstand the harsh conditions of the open sea. Ships also have a superstructure, which houses the crew, passengers, and cargo.

Ships are operated by a crew that includes the captain, officers, engineers, and deckhands. The crew is responsible for operating the ship, maintaining its systems, and ensuring the safety of everyone on board. Ships are subject to international regulations and standards to ensure maritime safety and environmental protection.
