Rudder For Boat And Ship Was Invented by Chinese


Rudder - A rudder is a device situated on a boat or ship, which helps to turn the boat towards the desired direction. It is also used in aeroplanes as well. Before rudders were invented, boats had to be turned using a device known as oars, which resulted in wastage of a lot of time and energy.

Until Europeans adopted the rudder from the Chinese, Western ships had to make do with steering oars. This meant that long voyages of discovery by Europeans were impossible. The famous voyages of Christopher Columbus, Vasco da Gama, and others of their time were only made possible by the adoption of Chinese nautical technology. The oldest Western evidence for rudders is found in church carvings of about the year 1180. This is within a few years of the first European evidence for the ship’s compass. Rudders and compasses thus seem to have reached Europe at about the same time, which is hardly surprising, since they were so closely associated. The rudder enables one to steer a ship properly, and the compass helped one to decide where to steer it.

The world’s oldest representation of a rudder may be seen in Plate 136. This is a pottery model of a Chinese ship excavated from a tomb dated to the first century AD. The model is about one foot ten inches long, and its rope slinging tackle has long since rotted away. But a slung axial rudder may clearly be seen. (A slung rudder is one which can be raised and lowered by rope tackle or chains; when entering shallows, it is often desirable to pull the rudder up so that it will not be snapped off.) Chinese seagoing rudders grew to many times the size of a man. Huge ships with enormous rudders were used on the Chinese voyages of discovery which preceded the European ones. The Chinese sailed round the Cape of Good Hope in the opposite direction to that taken by the Europeans and at an earlier time. They were also first to discover Australia, landing at the site now called Port Darwin.

Chinese business using the Philippines as well as Indonesia was common; as well as business using the eastern coast connected with Africa was so comprehensive that pieces of broken Chinese porcelain should be found spread all up and down the actual beaches connected with Tanzania as well as Mozambique, dating back for centuries. The actual Chinese also created voyages towards the American continents, though it is doubtful whether they were return voyages. Many Asian affects have already been identified in ancient The us by Needham and others. But the Chinese who arrived were potentially stranded, unable to return home, owing to the higher trouble connected with sailing westwards across the Pacific. Another traditional Chinese invention was the ‘fenestrated rudder’, which is merely a rudder having gaps made in it. The actual Chinese quickly found that while easing the task connected with turning the actual rudder over the water, the actual gaps did not appreciably diminish its steering function. However , it was not until 1901 that fenestrated rudders were introduced to the actual West. Until that time, a coal-fired torpedo boat touring on 30 knots was unable to turn its rudder on acceleration. Fenestration made this possible.

It is said that the rudder was invented in China way back during the 1st century AD. It was during the reign of the Han Dynasty that the first use of rudder was seen. Rudder was discovered in the Guangzhou district of China. It is interesting to note that the world’s first and oldest model of a ship’s rudder was found on a model made out of pottery, in China.
