Galleon

Galleons were large, multi-decked sailing ships developed in Spain and Portugal and first used as armed cargo carriers by Europeans from the 16th to 18th centuries during the Age of Sail and were the principal vessels drafted for use as warships until the Anglo-Dutch Wars of the mid-17th century. Galleons generally carried three or more masts with a lateen fore-and-aft rig on the rear masts, were carvel built with a prominent squared off raised stern, and used square-rigged sail plans on their fore-mast and main-masts.
Such ships played a major role in commerce in the sixteenth and seventeenth centuries and were often drafted into use as auxiliary naval war vessels—indeed, they were the mainstay of contending fleets through most of the 150 years of the Age of Exploration—before the Anglo-Dutch wars made purpose-built warships dominant at sea during the remainder of the Age of Sail.
The word galleon has had differing meanings at different points in its history and in different regions. The term is thought to originate from gallioni (alternatively galeanni), Venetian oared vessels that were used in rivers in the fifteenth century. The galleons of the sixteenth and seventeenth centuries were fully developed sailing ships. This descriptive name was used notably in Spain, Portugal and Venice. However, inconsistency can be found, for example, in the use of "galleon" by the notaries who worked in the Basque shipbuilding region of northern Spain. Though most of the ships from this region were naos, some were galeones, but the two terms can be found being used as if they were interchangeable by some of the writers of the documents in the contemporary archives.
It is thought that the seamen of the Basque country of northern Spain were clear on the differences between a nao and a galeón, but what those distinguishing features were is not apparent to modern historians. A hypothesis has been put forward that the differences are more in the underwater hull shape – something which cannot be discerned in contemporary illustrations.
The terminological inconsistency of Basque-built ships continues into the present day. Archival research on the Red Bay wreck 24M has identified, with reasonable confidence, this ship to have been San Juan of Pasajes. She is described 26 times in six different contemporary documents with at least three different authors as a nao, and not once as a galeón. However, published archaeological work repeatedly refers to this ship as a galleon.
Outside of the Iberian peninsula, the term "galleon" was not often used. For instance, though English shipwrights certainly built galleon-type vessels, they simply referred to them as "ships". In present-day usage, these types are referred to as galleons, with the term "race-built galleon" being applied to those with lower upper-works. In Holland, a "pinnas" was a galleon-type ship and in the Baltic, "kravel" was used (a term connected with their carvel construction).
During the 16th century, a lowering of the carrack's forecastle and elongation of the hull gave the ocean-going ships an unprecedented level of stability in the water, and reduced wind resistance at the front, leading to a faster, more maneuverable vessel. The galleon differed from the carrack and other older types primarily by being longer, lower and narrower, with a square tuck stern instead of a round tuck, and by having a snout or head projecting forward from the bows below the level of the forecastle. While carracks could be very large for the time, with some Portuguese carracks over 1,000 tons, galleons were generally smaller, usually under 500 tons although some Manila galleons were to reach a displacement of 2,000 tons. With the introduction of the galleon in Portuguese India Armadas during the first quarter of the 16th century, carracks' armament was reduced as they became almost exclusively cargo ships (which is why the Portuguese carracks were pushed to such large sizes), leaving any fighting to be done to the galleons. One of the largest and most famous of Portuguese galleons was the São João Baptista (nicknamed Botafogo, "Spitfire"), a 1,000-ton galleon built in 1534, said to have carried 366 guns. Friar Manuel Homem says that this galleon mounted 366 bronze pieces of artillery, including the ones that garrisoned the high castles of stern and bow.
Carracks were usually lightly armed and used for transporting cargo in all the fleets of other Western European states, while galleons were stronger, more heavily armed, and also cheaper to build for the same displacement (five galleons could cost around the same as three carracks) and were therefore a much better investment for use as heavily armed cargo ships or warships. Galleons' design changed and improved through the application of various innovations, and they were particularly linked with the military capabilities of the Atlantic sea powers. It was the captains of the Spanish navy, Pedro Menéndez de Avilés and Álvaro de Bazán, who designed the definitive long and relatively narrow hulled galleon in the 1550s.
The galleon was powered entirely by wind, using sails carried on three or four masts, with a lateen sail continuing to be used on the last (usually third and fourth) masts. They were used in both military and trade applications, most famously in the Spanish treasure fleet, and the Manila galleons. While carracks played the leading role in early global explorations, galleons also played a part in the 16th and 17th centuries. In fact, galleons were so versatile that a single vessel might be refitted for wartime and peacetime roles several times during its lifespan. The galleon was the prototype of all square-rigged ships with three or more masts for over two and a half centuries, including the later full-rigged ship.
The principal warships of the opposing English and Spanish fleets in the 1588 confrontation of the Spanish Armada and in the 1589 confrontation of the English Armada were galleons, with the modified English race-built galleons developed by John Hawkins proving their great utility in combat, while the capacious Spanish galleons, designed primarily as transports, showed great endurance in the battles and in the long and stormy return home.
Galleons were constructed from oak (for the keel), pine (for the masts) and various hardwoods for hull and decking. Hulls were usually carvel-built. The expenses involved in galleon construction were enormous. Hundreds of expert tradesmen (including carpenters, pitch-melters, blacksmiths, coopers, shipwrights, etc.) worked for months before a galleon was seaworthy. To cover the expense, galleons were often funded by groups of wealthy businessmen who pooled resources for a new ship. Therefore, most galleons were originally consigned for trade, although those captured by rival states were usually put into military service.
The most common gun used aboard a galleon was the demi-culverin, although gun sizes up to demi-cannon were possible.
Because of the long periods often spent at sea and poor conditions on board, many of the crew often perished during the voyage; therefore advanced rigging systems were developed so that the vessel could be sailed home by an active sailing crew a fraction of the size aboard at departure.
The most distinguishing features of the galleon include the long, prominent beak or beakhead followed by a foremast and mainmast, both noticeably taller than the single or double lateen-rigged mizzenmasts with their sloped lateen-rig yards, and below the square quarter gallery at the stern. On average with three masts, in larger galleons, a fourth mast was added, usually another lateen-rigged mizzen, called the bonaventure mizzen.
The oldest known scale drawings in England are in a manuscript called "Fragments of Ancient Shipwrightry" made in about 1586 by Mathew Baker, a master shipwright. This manuscript, held at the Pepysian Library, Magdalene College, Cambridge, provides an authentic reference for the size and shape of typical English galleons built during this period. Based on these plans, the Science Museum, London has built a 1:48 scale model ship that is an exemplar of galleons of this era.
