Sailing ship
A sailing ship is a sea-going vessel that uses sails mounted on masts to harness the power of wind and propel the vessel. There is a variety of sail plans that propel sailing ships, employing square-rigged or fore-and-aft sails. Some ships carry square sails on each mast—the brig and full-rigged ship, said to be "ship-rigged" when there are three or more masts. Others carry only fore-and-aft sails on each mast, for instance some schooners. Still others employ a combination of square and fore-and-aft sails, including the barque, barquentine, and brigantine.
Early sailing ships were used for river and coastal waters in ancient Egypt and the Mediterranean. The Austronesian peoples developed maritime technologies that included the fore-and-aft crab-claw sail and with catamaran and outrigger hull configurations, which enabled the Austronesian expansion into the islands of the Indo-Pacific. This expansion originated in Taiwan BC and propagated through Island Southeast Asia, reaching Near Oceania BC, Hawaii AD, and New Zealand AD. The maritime trading network in the Indo-Pacific dates from at least 1500 BC. Later developments in Asia produced the junk and dhow—vessels that incorporated features unknown in Europe at the time.
European sailing ships with predominantly square rigs became prevalent during the Age of Discovery, when they crossed oceans between continents and around the world. In the European Age of Sail, a full-rigged ship was one with a bowsprit and three masts, each of which consists of a lower, top, and topgallant mast. Most sailing ships were merchantmen, but the Age of Sail also saw the development of large fleets of well-armed warships. The many steps of technological development of steamships during the 19th century provided slowly increasing competition for sailing ships—initially only on short routes where high prices could be charged. By the 1880s, ships with triple-expansion steam engines had the fuel efficiency to compete with sail on all major routes—and with scheduled sailings that were not affected by the wind direction. However, commercial sailing vessels could still be found working into the 20th century, although in reducing numbers and only in certain trades.
History
By the Age of Discovery—Sailing and steam ships coexisted for much of the 19th century. The steamers of the early part of the century had very poor fuel efficiency and were suitable only for a small number of roles, such as towing sailing ships and providing short route passenger and mail services. Both sailing and steam ships saw large technological improvements over the century. Ultimately the two large stepwise improvements in fuel efficiency of compound and then triple-expansion steam engines made the steamship, by the 1880s, able to compete in the vast majority of trades. Commercial sail still continued into the 20th century, with the last ceasing to trade by.
South China Sea and Austronesia
Early sea-going sailing vessels were used by the Austronesian peoples. The invention of catamarans, outriggers, and crab claw sails enabled the Austronesian Expansion at around 3000 to 1500 BC. From Taiwan, they rapidly colonized the islands of Maritime Southeast Asia, then sailed further onwards to Micronesia, Island Melanesia, Polynesia, and Madagascar. Austronesian rigs were distinctive in that they had spars supporting both the upper and lower edges of the sails, in contrast to western rigs which only had a spar on the upper edge.Large Austronesian trading ships with as many as four sails were recorded by Han dynasty scholars as the kunlun bo or K'un-lun po. They were booked by Chinese Buddhist pilgrims for passage to Southern India and Sri Lanka. Bas reliefs of large Javanese outriggers ships with various configurations of tanja sails are also found in the Borobudur temple, dating back to the 8th century CE.
By the 10th century AD, the Song dynasty started building the first Chinese seafaring junks, which adopted several features of the K'un-lun po. The junk rig in particular, became associated with Chinese coast-hugging trading ships. Junks in China were constructed from teak with pegs and nails; they featured watertight compartments and acquired center-mounted tillers and rudders. These ships became the basis for the development of Chinese warships during the Mongol Yuan dynasty, and were used in the unsuccessful Mongol invasions of Japan and Java.
The Ming dynasty saw the use of junks as long-distance trading vessels. Chinese Admiral Zheng He reportedly sailed to India, Arabia, and southern Africa on a trade and diplomatic mission. Literary lore suggests that his largest vessel, the "Treasure Ship", measured in length and in width, whereas modern research suggests that it was unlikely to have exceeded in length.
Mediterranean and Baltic
Sailing ships in the Mediterranean region date back to at least 3000 BC, when Egyptians used a bipod mast to support a single square sail on a vessel that mainly relied on multiple paddlers. Later the mast became a single pole, and paddles were supplanted with oars. Such vessels plied both the Nile and the Mediterranean coast. The Minoan civilization of Crete may have been the world's first thalassocracy brought to prominence by sailing vessels dating to before 1800 BC. Between 1000 BC and 400 AD, the Phoenicians, Greeks and Romans developed ships that were powered by square sails, sometimes with oars to supplement their capabilities. Such vessels used a steering oar as a rudder to control direction.Starting in the 8th century in Denmark, Vikings were building clinker-constructed longships propelled by a single, square sail, when practical, and oars, when necessary. A related craft was the knarr, which plied the Baltic and North Seas, using primarily sail power. The windward edge of the sail was stiffened with a beitass, a pole that fitted into the lower corner of the sail, when sailing close to the wind.
Indian Ocean
India's maritime history began during the 3rd millennium BCE when inhabitants of the Indus Valley initiated maritime trading contact with Mesopotamia. Indian kingdoms such as the Kalinga from as early as 2nd century CE are believed to have had sailing ships. One of the earliest instances of documented evidence of Indian sailing ship building comes from the mural of three-masted ship in the Ajanta caves that date back to 400-500 CE.The Indian Ocean was the venue for increasing trade between India and Africa between 1200 and 1500. The vessels employed would be classified as dhows with lateen rigs. During this interval such vessels grew in capacity from 100 to 400 tonnes. Dhows were often built with teak planks from India and Southeast Asia, sewn together with coconut husk fiber—no nails were employed. This period also saw the implementation of center-mounted rudders, controlled with a tiller.
Global exploration
Technological advancements that were important to the Age of Discovery in the 15th century were the adoption of the magnetic compass and advances in ship design.The compass was an addition to the ancient method of navigation based on sightings of the sun and stars. The compass was invented by Chinese. It had been used for navigation in China by the 11th century and was adopted by the Arab traders in the Indian Ocean. The compass spread to Europe by the late 12th or early 13th century. Use of the compass for navigation in the Indian Ocean was first mentioned in 1232. The Europeans used a "dry" compass, with a needle on a pivot. The compass card was also a European invention.
At the beginning of the 15th century, the carrack was the most capable European ocean-going ship. It was carvel-built and large enough to be stable in heavy seas. It was capable of carrying a large cargo and the provisions needed for very long voyages. Later carracks were square-rigged on the foremast and mainmast and lateen-rigged on the mizzenmast. They had a high rounded stern with large aftcastle, forecastle and bowsprit at the stem. As the predecessor of the galleon, the carrack was one of the most influential ship designs in history; while ships became more specialized in the following centuries, the basic design remained unchanged throughout this period.
Ships of this era were only able to sail approximately 70° into the wind and tacked from one side to the other across the wind with difficulty, which made it challenging to avoid shipwrecks when near shores or shoals during storms. Nonetheless, such vessels reached India around Africa with Vasco da Gama, the Americas with Christopher Columbus, and around the world under Ferdinand Magellan.
1700 to 1850
Sailing ships became longer and faster over time, with ship-rigged vessels carrying taller masts with more square sails. Other sail plans emerged, as well, that had just fore-and-aft sails, or a mixture of the two.Warships
were introduced in the 14th century, but did not become common at sea until they could be reloaded quickly enough to be reused in the same battle. The size of a ship required to carry a large number of cannon made oar-based propulsion impossible, and warships came to rely primarily on sails. The sailing man-of-war emerged during the 16th century.By the middle of the 17th century, warships were carrying increasing numbers of cannon on three decks. Naval tactics evolved to bring each ship's firepower to bear in a line of battle—coordinated movements of a fleet of warships to engage a line of ships in the enemy fleet. Carracks with a single cannon deck evolved into galleons with as many as two full cannon decks, which evolved into the man-of-war, and further into the ship of the line—
