Square rig in the context of "Sailing ships"

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 c. 3000 BC and propagated through Island Southeast Asia, reaching Near Oceania c. 1500 BC, Hawaii c. 900 AD, and New Zealand c. 1200 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.

The caravel (Portuguese: caravela, IPA: [kɐɾɐˈvɛlɐ]) was a small sailing ship developed by Portugal. It could be rigged either entirely with lateen sails or with a combination of lateen and square sails. It was known for its agility and speed and its capacity for sailing windward (beating). Caravels were used by the Portuguese and, later, by the Spanish for the voyages of exploration during the 15th and 16th centuries, in the Age of Exploration.

The caravel is a poorly understood type of vessel. Though there are now some archaeologically investigated wrecks that are most likely caravels, information on this type is limited. We have a better understanding of the ships of the Greeks and Romans of classical antiquity than we do of the caravel.

Rigging comprises the system of ropes, cables and chains, which support and control a sailing ship or sail boat's masts and sails. Standing rigging is the fixed rigging that supports masts including shrouds and stays. Running rigging is rigging which adjusts the position of the vessel's sails and spars including halyards, braces, sheets and vangs.

A ship is a large watercraft designed for travel across the surface of a body of water, carrying cargo or passengers, or in support of specialized tasks such as warfare, oceanography and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. Ship transport is responsible for the largest portion of world commerce.

The word ship has meant, depending on era and context, either simply a large vessel or specifically a full-rigged ship with three or more masts, each of which is square rigged.

A barque, barc, or bark is a type of sailing vessel with three or more masts of which the fore mast, mainmast, and any additional masts are rigged square, and only the aftmost mast (mizzen in three-masted barques) is rigged fore and aft. Sometimes, the mizzen is only partly fore-and-aft rigged, bearing a square-rigged sail above.

Santa Catarina do Monte Sinai was a higher-castled Portuguese carrack with 140 guns, launched down in 1520 (800 t, length 38 m, width 13 m, draft 4–4.5 m). Built in Kochi, India around 1512 it had two square rig masts and is depicted on a painting attributed to Joachim Patinir.

In 1524, it was the flagship of Vasco da Gama, on his third voyage to India.

A cog is a type of ship that was used during the Middle Ages, mostly for trade and transport but also in war. It first appeared in the 10th century, and was widely used from around the 12th century onward. Cogs were clinker-built, generally of oak. Cogs were fitted with a single mast and a single square sail. They were used primarily for trade in north-west medieval Europe, especially by the Hanseatic League. Typical seagoing cogs were from 15 to 25 meters (49 to 82 ft) long, 5 to 8 meters (16 to 26 ft) wide, and were of 30–200 tons burthen. Cogs were rarely as large as 300 tons although a few were considerably larger, over 1,000 tons.

Although the name cog is recorded as early as the 9th century, the seagoing vessel of that name seems to have evolved on the Frisian coast during the 12th century. Cogs progressively replaced Viking-type vessels such as knarrs in northern waters during the 13th century. Cogs could carry more cargo than knarrs of a similar size. Their flat bottoms allowed them to settle on a level in harbour, making them easier to load and unload. Their high sides made them more difficult to board in a sea fight, which made them safer from pirates.

Alan John Villiers, DSC (23 September 1903 – 3 March 1982) was a writer, adventurer, photographer and mariner.

Born in Melbourne, Australia, Villiers first went to sea at age 15 and sailed on board traditionally rigged vessels, including the full-rigged ship Joseph Conrad. He commanded square-rigged ships for films, including Moby Dick and Billy Budd. He also commanded the Mayflower II on its voyage from the United Kingdom to the United States.

A fore-and-aft rig is a sailing ship rig with sails set mainly in the median plane of the keel, rather than perpendicular to it, as on a square-rigged vessel.
