s. 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.

starting in the 15th century—square-rigged, multi-masted vessels were the norm and were guided by navigation techniques that included the magnetic compass and making sightings of the sun and stars that allowed transoceanic voyages. The Age of Sail reached its peak in the 18th and 19th centuries with large, heavily armed battleships and merchant sailing ships. 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

, sailing ships were equipped with fore-and-aft rigs that made sailing to windward possible. Later square-rigged vessels too were able to sail to windward, and became the standard for European ships through the Age of Discovery when vessels ventured around Africa to India, to the Americas and around the world. Later during this period—in the late 15th century—"ship-rigged" vessels with multiple square sails on each mast appeared and became common for sailing ships.

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

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

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

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 (

Warships

Cannons 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 linedesigned for engaging the enemy in a line of battle. One side of a ship was expected to shoot broadsides against an enemy ship at close range.

Copper sheathing

During the Age of Sail, ships' hulls were under frequent attack by shipworm (which affected the structural strength of timbers), and barnacles and various marine weeds (which affected ship speed). Since before the common era, a variety of coatings had been applied to hulls to counter this effect, including pitch, wax, tar, oil, sulfur and arsenic. In the mid 18th century copper sheathing was developed as a defense against such bottom fouling. After coping with problems of galvanic deterioration of metal hull fasteners, sacrificial anodes were developed, which were designed to corrode, instead of the hull fasteners. The practice became widespread on naval vessels, starting in the late 18th century, and on merchant vessels, starting in the early 19th century, until the advent of iron and steel hulls.


After 1850

Iron-hulled sailing ships, often referred to as " windjammers" or " tall ships", represented the final evolution of sailing ships at the end of the Age of Sail. They were built to carry bulk cargo for long distances in the nineteenth and early twentieth centuries. They were the largest of merchant sailing ships, with three to five masts and square sails, as well as other sail plans. They carried

or ore between continents. Later examples had steel hulls. Iron-hulled sailing ships were mainly built from the 1870s to 1900, when steamships began to outpace them economically, due to their ability to keep a schedule regardless of the wind. Steel hulls also replaced iron hulls at around the same time. Even into the twentieth century, sailing ships could hold their own on transoceanic voyages such as Australia to Europe, since they did not require bunkerage for coal nor fresh water for steam, and they were faster than the early steamers, which usually could barely make . The four-masted, iron-hulled ship, introduced in 1875 with the full-rigged , represented an especially efficient configuration that prolonged the competitiveness of sail against steam in the later part of the 19th century. The largest example of such ships was the five-masted,

This was developed in the 1960s in Germany as a low-carbon footprint propulsion alternative for commercial ships. The rig automatically sets and reefs sails; its mast rotates to align the sails with the wind. The sailing yachts '' Maltese Falcon'' and '' Black Pearl'' employ the rig.

, rigging and masts to hold up the sails that use the wind to power the ship; the masts are supported by standing rigging and the sails are adjusted by running rigging.


Hull

Hull shapes for sailing ships evolved from being relatively short and blunt to being longer and finer at the bow. By the nineteenth century, ships were built with reference to a half model, made from wooden layers that were pinned together. Each layer could be scaled to the actual size of the vessel in order to lay out its hull structure, starting with the keel and leading to the ship's ribs. The ribs were pieced together from curved elements, called futtocks and tied in place until the installation of the planking. Typically, planking was caulked with a tar-impregnated yarn made from manila or hemp to make the planking watertight. Starting in the mid-19th century, iron was used first for the hull structure and later for its watertight sheathing.


Masts

Until the mid-19th century all vessels' masts were made of wood formed from a single or several pieces of timber which typically consisted of the trunk of a

tree. From the 16th century, vessels were often built of a size requiring masts taller and thicker than could be made from single tree trunks. On these larger vessels, to achieve the required height, the masts were built from up to four sections (also called masts), known in order of rising height above the decks as the lower, top, topgallant and royal masts. Giving the lower sections sufficient thickness necessitated building them up from separate pieces of wood. Such a section was known as a ''made mast'', as opposed to sections formed from single pieces of timber, which were known as ''pole masts''. Starting in the second half of the 19th century, masts were made of iron or steel. For ships with square sails the principal masts, given their standard names in bow to stern (front to back) order, are: * ''Fore-mast'' — the mast nearest the bow, or the mast forward of the main-mast with sections: fore-mast lower, fore topmast, and fore topgallant mast * ''Main-mast'' — the tallest mast, usually located near the center of the ship with sections: main-mast lower, main topmast, main topgallant mast, royal mast (sometimes) * ''Mizzen-mast'' — the aft-most mast. Typically shorter than the fore-mast with sections: mizzen-mast lower, mizzen topmast, and mizzen topgallant mast.


Sails

Each rig is configured in a ''sail plan'', appropriate to the size of the sailing craft. Both square-rigged and fore-and-aft rigged vessels have been built with a wide range of configurations for single and multiple masts. Types of sail that can be part of a sail plan can be broadly classed by how they are ''attached'' to the sailing craft: * ''To a stay'' — Sails attached to stays, include jibs, which are attached to forestays and staysails, which are mounted on other stays (typically wire cable) that support other masts from the bow aft. * ''To a mast'' — Fore-and-aft sails directly attached to the mast at the luff include gaff-rigged quadrilateral and

triangular sails. * ''To a spar'' — Sails attached to a spar include both square sails and such fore-and-aft quadrilateral sails as lug rigs, junk and spritsails and such triangular sails as the lateen, and the crab claw.


Rigging

Sailing ships have ''standing rigging'' to support the masts and ''running rigging'' to raise the sails and control their ability to draw power from the wind. The running rigging has three main roles, to support the sail structure, to shape the sail and to adjust its angle to the wind. Square-rigged vessels require more controlling lines than fore-and-aft rigged ones.


Standing rigging

Sailing ships prior to the mid-19th century used wood masts with hemp-fiber standing rigging. As rigs became taller by the end of the 19th century, masts relied more heavily on successive spars, stepped one atop the other to form the whole, from bottom to top: the ''lower mast'', ''top mast'', and ''topgallant mast''. This construction relied heavily on support by a complex array of stays and shrouds. Each stay in either the fore-and-aft or athwartships direction had a corresponding one in the opposite direction providing counter-tension. Fore-and-aft the system of tensioning started with the stays that were anchored in front each mast. Shrouds were tensioned by pairs deadeyes, circular blocks that had the large-diameter line run around them, whilst multiple holes allowed smaller line—''lanyard''—to pass multiple times between the two and thereby allow tensioning of the shroud. After the mid-19th century square-rigged vessels were equipped with iron wire standing rigging, which was superseded with steel wire in the late 19th century.


Running rigging

Halyards, used to raise and lower the yards, are the primary supporting lines. In addition, square rigs have lines that lift the sail or the yard from which it is suspended that include: brails, buntlines, lifts and leechlines. Bowlines and clew lines shape a square sail. To adjust the angle of the sail to wind braces are used to adjust the fore and aft angle of a yard of a square sail, while

attach to the clews (bottom corners) of a sail to control the sail's angle to the wind. Sheets run aft, whereas tacks are used to haul the clew of a square sail forward.


Crew

The crew of a sailing ship is divided between officers (the captain and his subordinates) and seamen or ''ordinary'' ''hands''. An able seaman was expected to "hand, reef, and steer" (handle the lines and other equipment, reef the sails, and steer the vessel). The crew is organized to stand

—the oversight of the ship for a period—typically four hours each. Richard Henry Dana Jr. and Herman Melville each had personal experience aboard sailing vessels of the 19th century.


Merchant vessel

Dana described the crew of the merchant brig, ''Pilgrim'', as comprising six to eight common sailors, four specialist crew members (the steward, cook, carpenter and sailmaker), and three officers: the captain, the first mate and the second mate. He contrasted the American crew complement with that of other nations on whose similarly sized ships the crew might number as many as 30. Larger merchant vessels had larger crews.


Warship

Melville described the crew complement of the frigate warship, ''

'', as about 500—including officers, enlisted personnel and 50 Marines. The crew was divided into the starboard and larboard watches. It was also divided into three ''tops'', bands of crew responsible for setting sails on the three masts; a band of ''sheet-anchor men'', whose station was forward and whose job was to tend the fore-yard, anchors and forward sails; the ''after guard'', who were stationed aft and tended the mainsail, spanker and man the various sheets, controlling the position of the sails; the ''waisters'', who were stationed midships and had menial duties attending the livestock, etc.; and the ''holders'', who occupied the lower decks of the vessel and were responsible for the inner workings of the ship. He additionally named such positions as, boatswains, gunners, carpenters, coopers, painters, tinkers, stewards, cooks and various boys as functions on the man-of-war. 18-19th century ships of the line had a complement as high as 850.


Ship handling

Handling a sailing ship requires management of its sails to power—but not overpower—the ship and navigation to guide the ship, both at sea and in and out of harbors.


Under sail

Key elements of sailing a ship are setting the right amount of sail to generate maximum power without endangering the ship, adjusting the sails to the wind direction on the course sailed, and changing tack to bring the wind from one side of the vessel to the other.


Setting sail

A sailing ship crew manages the running rigging of each square sail. Each sail has two sheets that control its lower corners, two braces that control the angle of the yard, two clewlines, four buntlines and two reef tackles. All these lines must be manned as the sail is deployed and the yard raised. They use a halyard to raise each yard and its sail; then they pull or ease the braces to set the angle of the yard across the vessel; they pull on sheets to haul lower corners of the sail, ''clews'', out to yard below. Under way, the crew manages ''reef tackles'', ''haul leeches'', ''reef points'', to manage the size and angle of the sail; ''bowlines'' pull the leading edge of the sail (''leech'') taut when close hauled. When furling the sail, the crew uses ''clewlines'', haul up the clews and ''buntlines'' to haul up the middle of sail up; when lowered, ''lifts'' support each yard. In strong winds, the crew is directed to reduce the number of sails or, alternatively, the amount of each given sail that is presented to the wind by a process called ''reefing''. To pull the sail up, seamen on the yardarm pull on ''reef tackles'', attached to ''reef cringles'', to pull the sail up and secure it with lines, called ''reef points''. Dana spoke of the hardships of sail handling during high wind and rain or with ice covering the ship and its rigging.


Changing tack

Sailing vessels cannot sail directly into the wind. Instead, square-riggers must sail a course that is between 60° and 70° away from the wind direction and fore-and aft vessels can typically sail no closer than 45°. To reach a destination, sailing vessels may have to change course and allow the wind to come from the opposite side in a procedure, called ''tacking'', when the wind comes across the bow during the maneuver. When tacking, a square-rigged vessel's sails must be presented squarely to the wind and thus impede forward motion as they are swung around via the yardarms through the wind as controlled by the vessel's running rigging, using braces—adjusting the fore and aft angle of each yardarm around the mast—and

), pulled to windward to help turn the ship through the eye of the wind. Once the ship has come about, all the sails are adjusted to align properly with the new tack. Because square-rigger masts are more strongly braced from behind than from ahead, tacking is a dangerous procedure in strong winds; the ship may lose forward momentum (become ''caught in stays'') and the rigging may fail from the wind coming from ahead. The ship may also lose momentum at wind speeds of less than . Under these conditions, the choice may be to ''wear ship''—to turn the ship away from the wind and around 240° onto the next tack (60° off the wind). A fore-and-aft rig permits the wind to flow past the sail, as the craft head through the eye of the wind. Most rigs pivot around a stay or the mast, while this occurs. For a jib, the old leeward sheet is released as the craft heads through the wind and the old windward sheet is tightened as the new leeward sheet to allow the sail to draw wind. Mainsails are often self-tending and slide on a traveler to the opposite side. On certain rigs, such as lateens and

Navigation

Early navigational techniques employed observations of the sun, stars, waves and birdlife. In the 15th century, the Chinese were using the magnetic compass to identify direction of travel. By the 16th century in Europe, navigational instruments included the quadrant, the

. Passage planning begins with laying out a route along a chart, which comprises a series of courses between fixes—verifiable locations that confirm the actual track of the ship on the ocean. Once a course has been set, the person at the helm attempts to follow its direction with reference to the compass. The navigator notes the time and speed at each fix to estimate the arrival at the next fix, a process called dead reckoning. For coast-wise navigation, sightings from known landmarks or navigational aids may be used to establish fixes, a process called pilotage. At sea, sailing ships used celestial navigation on a daily schedule, as follows: # Continuous dead reckoning plot # Star observations at morning twilight for a celestial fix # Morning sun observation to determine compass error by azimuth observation of the sun # Noontime observation of the sun for noon latitude line for determination the day's run and day's set and drift # Afternoon sun line to determine compass error by azimuth observation of the sun # Star observations at evening twilight for a celestial fix Fixes were taken with a marine sextant, which measures the distance of the celestial body above the horizon.


Entering and leaving harbor

Given the limited maneuverability of sailing ships, it could be difficult to enter and leave harbor with the presence of a tide without coordinating arrivals with a flooding tide and departures with an ebbing tide. In harbor, a sailing ship stood at anchor, unless it needed to be loaded or unloaded at a dock or pier, in which case it might be warped alongside or towed by a tug. Warping involved using a long rope (the warp) between the ship and a fixed point on the shore. This was pulled on by a capstan on shore, or on the ship. This might be a multi-stage process if the route was not simple. If no fixed point was available, a kedge anchor might be taken out in a ship's boat to a suitable point and the ship then pulled up to the kedge. Square rigged vessels could use backing and filling (of the sails) to manoeuvre in a tideway, or control could be maintained by drudging the anchor - lower the anchor until it touches the bottom so that the dragging anchor gives steerage way in the flow of the tide.
