Such ships were the mainstay of maritime commerce into the early 19th century, and were often drafted into use as auxiliary naval war vessels—indeed, were the mainstay of contending fleets through most of the 150 years of the Age of Exploration—before the Anglo-Dutch wars brought purpose-built ship-rigged warships, ships of the line, that thereafter dominated war at sea during the remainder of the age of sail.

Etymology

The word galleon 'large ship' comes from Old French galion 'armed ship of burden' or from (Castilian) Spanish galeón 'galleon, armed merchant ship', (perhaps via Italian galeone 'big galea, big galley') from Medieval Greek galea 'galley', to which the French or Spanish augmentative suffix -on is added. Another possible origin is the Old French word galie 'galley'; also from Medieval Greek galea. The galea was a warship of the Byzantine navy, and its name may be related to the Greek word galeos 'dogfish shark'. The term was originally given to certain types of war galleys in the Middle Ages.

The Annali Genovesi mention galleons of 60, 64 and 80 oars, used for battle and on missions of exploration, in the 12th and 13th centuries. It is very likely that the galleons and galliots mentioned in the accounts of the crusades were the same vessels. In the early 16th century, the Venetian galleoni were a new class of galley used to hunt down pirates in the Mediterranean.

Later, when the term started to be applied to sail-only vessels, it meant, like the English term "man-of-war", any large warship that was otherwise no different from the other sailing ships of the time.

History

In the beginning of the 16th century, a lowering of the carrack's forecastle and elongation of the hull gave the ocean-going galleons 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 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. In Portugal at least, Portuguese carracks were usually very large ships for their time (often over 1,000 tons), while galleons were mostly under 500 tons, although the Manila galleons were to reach up to 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.

Carracks also tended to be lightly armed and used for transporting cargo in all the fleets of other Western European states, while galleons were purpose-built warships, and were stronger, more heavily armed, and also cheaper to build (five galleons could cost around the same as three carracks) and were therefore a much better investment for use as warships or transports. There are disputes about its origins and development but each Atlantic sea power built types suited to its needs, while constantly learning from their rivals. 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 for Spain 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.

Construction

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.

Distinguishing features[edit]

Galleons were a class of blue-water sailing ship that combined the easy-to-maneuver fore-and-aft rig of smaller shipping (boats) with the square rig of late middle ages cargo vessels. The galleons solidified the place of the square-rig and the centrally situated tallest main-masts and the slightly shorter fore-masts of a square-rigged ship characteristic of the 16th–19th centuries, but introduced the use of the lateen rig to sail closer to the wind on a tack than could a square-rigged vessel—an important attribute in restricted waters, but more so over long voyages where holding a few compass points closer to the wind might save hundreds of miles and days or weeks of sailing 'beating into the wind'.

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 those 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 galleon continued to be used into the 18th century, by which time purpose-built vessels such as the fluyt, the brig and the full-rigged ship, both as a trading vessel and ship of the line, rendered it obsolete for trade and warfare respectively.
