What was developed to allow ships to sail into the wind?
lateen
One of the biggest jumps in the history of sailing technology was the invention of the lateen or latin-rig sail. The lateen is a triangular sail mounted at an angle and running in a fore-and-aft direction. With a manoeuvre called ‘tacking,’ the sail allows boats to make way to windward in a zig-zagging fashion.
How does the lateen sail allow you to sail into the wind?
The sail, its free corner secured near the stern, was capable of taking the wind on either side, and, by enabling the vessel to tack into the wind, the lateen immensely increased the potential of the sailing ship.
How does a Chinese junk sail work?
The junk sail will swing out with the wind around the unstayed mast. Releasing the sheet while reaching or running on a Bermuda rigged boat would cause the sail and boom to hit the shrouds, which are part of the standing rigging.
Did the Chinese invent ships?
The square ship in the Warring States era was already double-bodied and made up of two junks secured together side by side. Third century warships had eight compartments. Paddle-wheel boats were invented in the late Tang and widely used in the Song.
What were Chinese sailing ships quizlet?
A junk is an Chinese sailing vessel/ship design still in use today. Junks were developed during the Song Dynasty (960-1129)[1] and were used as seagoing vessels as early as the 2nd century CE.
How do you sail into the wind?
Sailing into the wind is possible when the sail is angled in a slightly more forward direction than the sail force. In that aspect, the boat moves forward because the keel (centreline) of the boat acts to the water as the sail acts to the wind. The force of the sail is balanced by the force of the keel.
Why is a Chinese ship called a junk?
The origin of the word “junk” in the English language can be traced to the Portuguese word junco, which is rendered from the Arabic word j-n-k (جنك). The word was used to denote both the Javanese/Malay ship (jong or djong) and the Chinese ship (chuán), even though the two were markedly different vessels.
What were Chinese junk ships made of?
junk, classic Chinese sailing vessel of ancient unknown origin, still in wide use. High-sterned, with projecting bow, the junk carries up to five masts on which are set square sails consisting of panels of linen or matting flattened by bamboo strips.
