Ships are large watercraft at sea that are specially designed to cover long distances in the water at the same time. They can also carry heavy loads. They usually have multiple decks and can carry lifeboats and dinghies in addition to their cargo. The ship sizes vary depending on the intended use and are often regulated by applicable laws. Although the size of the ship depends largely on the purpose of a ship, there are still huge ships that are built for prestigious reasons. Years ago, a country’s ability to produce a giant ship was viewed as a national pride that would show how rich and powerful a country is. Ships are currently used for cruises; for transporting people to many parts of the world; as a transport company for the transport of heavy loads and goods from port to port; or as warships to protect the waters.
Before the 19th century, ships were propelled by rowing galleys or sails, or even a combination of the two. This way of propelling ships was responsible for the time it took ships to travel great distances and the effort it took to sail them. This offered less maneuverability given the weight of the ships, so more ways to propel ships were developed in order to develop more efficient ships.
In 1807, the United States launched the first successful steamship, designed by Robert Fulton. Europe immediately followed this trend in 1812. The use of steam engines in ship propulsion was based on the energy generated by steam. This energy was enough to propel the ships and make them more efficient. Condensers, which were also developed during this period, significantly reduced the need for fresh water. Several expansion engines allowed the ships to go even faster. Despite their heavy weight, the steam turbines maximized the ships’ performance. These were introduced as the next generation of high-speed watercraft as we know them today.
It was not until 1912 that diesel engines made a name for themselves in the shipping industry, replacing heavy coal as the ship’s main fuel. These engines were even more efficient because they were much lighter than coal. In addition, coal heaters were no longer needed to power ships.
