A carrack was a three- or four-masted ocean-going sailing ship that was developed in the 14th to 15th centuries in Europe (mainly Portugal). Evolved from the single-masted cog, the carrack was first used for European trade from the Mediterranean to the Baltic and quickly found use with the newly found wealth of the trans-Atlantic trade between Europe, Africa and then the Americas. In their most advanced forms, they were used by the Portuguese for trade between Europe and Asia starting in the late 15th century, before eventually being superseded in the 17th century by the galleon, introduced in the 16th century.
In its most developed form, the carrack was a carvel-built ocean-going ship: large enough to be stable in heavy seas, and for a large cargo and the provisions needed for very long voyages. The 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.
English carrack was loaned in the late 14th century, via Old French caraque, from carraca, a term for a large, square-rigged sailing vessel used in Spanish, Italian and Middle Latin.
The origin of the term carraca is unclear, perhaps from Arabic qaraqir "merchant ship", itself of unknown origin (maybe from Latin carricare "to load a car" or Greek "load of timber") or the Arabic (Al-qurqoor) and from thence to the Greek (kerkouros) meaning approximately "lighter" (barge) (literally, "shorn tail", a possible reference to the ship's flat stern). Its attestation in Greek literature is distributed in two closely related lobes. The first distribution lobe, or area, associates it with certain light and fast merchantmen found near Cyprus and Corfu. The second is an extensive attestation in the Oxyrhynchus corpus, where it seems most frequently to describe the Nile barges of the Ptolemaic pharaohs. Both of these usages may lead back through the Phoenician to the Akkadian kalakku, which denotes a type of river barge. The Akkadian term is assumed to be derived from a Sumerian antecedent. A modern reflex of the word is found in Arabic and Turkish kelek "raft; riverboat".
By the Late Middle Ages the cog, and cog-like square-rigged vessels equipped with a rudder at the stern, were widely used along the coasts of Europe, from the Mediterranean, to the Baltic. Given the conditions of the Mediterranean, galley type vessels were extensively used there, as were various two masted vessels, including the caravels with their lateen sails. These and similar ship types were familiar to Portuguese navigators and shipwrights. As the Portuguese gradually extended their trade ever further south along Africa's Atlantic coast during the 15th century, they needed a larger, more durable and more advanced sailing ships for their long oceanic ventures. Gradually, they developed their own models of oceanic carracks from a fusion and modification of aspects of the ship types they knew operating in both the Atlantic and Mediterranean, generalizing their use in the end of the century for inter-oceanic travel with a more advanced form of sail rigging that allowed much improved sailing characteristics in the heavy winds and waves of the Atlantic Ocean and a hull shape and size that permitted larger cargoes. In addition to the average tonnage naus, some large naus (carracks) were also built in the reign of John II of Portugal, but were only widespread after the turn of the century. The Portuguese carracks were usually very large ships for their time, often over 1000 tons, and having the future large naus of the India run and of the China and Japan trade, also other new types of design.
A typical three-masted carrack such as the São Gabriel had six sails: bowsprit, foresail, mainsail, mizzensail and two topsails.
In the middle of the 16th century the first galleons were developed from the carrack. The galleon design came to replace that of the carrack although carracks were still in use as late as the middle of the 17th century due to their larger cargo capacity.
Starting in 1498, Portugal initiated for the first time direct and regular exchanges between Europe and India - and the rest of Asia thereafter - through the Cape Route, a journey that required the use of larger vessels, such as carracks, due to its unprecedented length, about 6 months.
On average 4 carracks connected Lisbon to Goa carrying gold to purchase spices and other exotic items, but mainly pepper. From Goa, one carrack went on to Ming China in order to purchase silks. Starting in 1541, the Portuguese began trading with Japan, exchanging Chinese silk for Japanese silver; in 1550 the Portuguese Crown started to regulate trade to Japan, by leasing the annual "captaincy" to Japan to the highest bidder at Goa, in effect conferring exclusive trading rights for a single carrack bound for Japan every year. In 1557 the Portuguese acquired Macau to develop this trade in partnership with the Chinese. That trade continued with few interruptions until 1638, when it was prohibited by the rulers of Japan on the grounds that the ships were smuggling Catholic priests into the country. The Japanese called Portuguese carracks "Black Ships" (kurofune), referring to the colour of the ship's hulls. This term would eventually come to refer to any western vessel, not just Portuguese.
