The spanker is the fore-and-aft sail at the lower right.

On a square rigged ship, the spanker is a gaff-rigged fore-and-aft sail set from, and aft of, the aftmost mast. [1] [2] [3] Spankers are also called driver, jigger, and a pusher sail. [4]

On a schooner of four or more masts, the spanker is the sail on the mast nearest the stern. [5]

The spanker is a small sail, but as it is so far aft of the balance point of the hull, it has strong leverage. When sheeted in, the spanker is important in driving the boat to a new tack. [4]

A sloop is a sailboat with a single mast typically having only one headsail in front of the mast and one mainsail aft of (behind) the mast. Such an arrangement is called a fore-and-aft rig, and can be rigged as a Bermuda rig with triangular sails fore and aft, or as a gaff-rig with triangular foresail(s) and a gaff rigged mainsail.

<span class="mw-page-title-main">Rigging</span> Ropes, cables and chains which support masts of sailing ships

Rigging comprises the system of ropes, cables and chains, which support a sailing ship or sail boat's masts—standing rigging, including shrouds and stays—and which adjust the position of the vessel's sails and spars to which they are attached—the running rigging, including halyards, braces, sheets and vangs.

<span class="mw-page-title-main">Sailing ship</span> Large wind-powered water vessel

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.

<span class="mw-page-title-main">Sailing rigs</span> Description of the specific ways that a sailing craft is rigged

Sailing rigs describe the arrangement of sailing vessels' rig components, including their spars, rigging, and sails. Examples include a schooner rig, cutter rig, junk rig, etc. Rigs may be broadly categorized as fore-and-aft and square-rigged. They may incorporate a mixture of both categories. Within the fore-and-aft category there is a variety of triangular and quadrilateral sail shapes. Spars or battens may be used to help shape a given kind of sail. Each rig may be described with a sail plan—formally, a drawing of a vessel, viewed from the side.

<span class="mw-page-title-main">Brigantine</span> Two-masted sailing vessel

A brigantine is a two-masted sailing vessel with a fully square-rigged foremast and at least two sails on the main mast: a square topsail and a gaff sail mainsail. The main mast is the second and taller of the two masts.

<span class="mw-page-title-main">Brig</span> Sailing vessel with two square-rigged masts

A brig is a type of sailing vessel defined by its rig: two masts which are both square-rigged. Brigs originated in the second half of the 18th century and were a common type of smaller merchant vessel or warship from then until the latter part of the 19th century. In commercial use, they were gradually replaced by fore-and-aft rigged vessels such as schooners, as owners sought to reduce crew costs by having rigs that could be handled by fewer men. In Royal Navy use, brigs were retained for training use when the battle fleets consisted almost entirely of iron-hulled steamships.

<span class="mw-page-title-main">Jibe</span> Basic sailing maneuver, where ship turns its stern through the wind

A jibe (US) or gybe (Britain) is a sailing maneuver whereby a sailing vessel reaching downwind turns its stern through the wind, which then exerts its force from the opposite side of the vessel. Because the mainsail boom can swing across the cockpit quickly, jibes are potentially dangerous to person and rigging compared to tacking. Therefore accidental jibes are to be avoided while the proper technique must be applied so as to control the maneuver. For square-rigged ships, this maneuver is called wearing ship.

<span class="mw-page-title-main">Topsail</span> Sail set above another sail

A topsail ("tops'l") is a sail set above another sail; on square-rigged vessels further sails may be set above topsails.

<span class="mw-page-title-main">Mainsail</span> Sail rigged to the main mast of a sailing vessel

A mainsail is a sail rigged on the main mast of a sailing vessel.

<span class="mw-page-title-main">Barquentine</span> Sailing rig

A barquentine or schooner barque is a sailing vessel with three or more masts; with a square rigged foremast and fore-and-aft rigged main, mizzen and any other masts.

<span class="mw-page-title-main">Gaff rig</span> Sailing rig configuration

Gaff rig is a sailing rig in which the sail is four-cornered, fore-and-aft rigged, controlled at its peak and, usually, its entire head by a spar (pole) called the gaff. Because of the size and shape of the sail, a gaff rig will have running backstays rather than permanent backstays.

<span class="mw-page-title-main">Running rigging</span> Lines that control sails

Running rigging is the rigging of a sailing vessel that is used for raising, lowering, shaping and controlling the sails on a sailing vessel—as opposed to the standing rigging, which supports the mast and bowsprit. Running rigging varies between vessels that are rigged fore and aft and those that are square-rigged.

<span class="mw-page-title-main">Full-rigged ship</span> Sailing vessel with three or more square-rigged masts

A full-rigged ship or fully rigged ship is a sailing vessel with a sail plan of three or more masts, all of them square-rigged. Such a vessel is said to have a ship rig or be ship-rigged, with each mast stepped in three segments: lower, top, and topgallant.

<span class="mw-page-title-main">Fore-and-aft rig</span> Sailing rig consisting mainly of sails

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

<span class="mw-page-title-main">Tacking (sailing)</span> A sailing maneuver

Tacking or coming about is a sailing maneuver by which a sailing craft, whose next destination is into the wind, turns its bow toward and through the wind so that the direction from which the wind blows changes from one side of the boat to the other, allowing progress in the desired direction. Sailing vessels are unable to sail higher than a certain angle towards the wind, so "beating to windward" in a zig-zag fashion with a series of tacking maneuvers, allows a vessel to sail towards a destination that is closer to the wind that the vessel can sail directly.

<span class="mw-page-title-main">Jackass-barque</span>

A jackass-barque, sometimes spelled jackass bark, is a sailing ship with three masts, of which the foremast is square-rigged and the main is partially square-rigged and partially fore-and-aft rigged (course). The mizzen mast is fore-and-aft rigged.

A mast-aft rig is a sailboat sail-plan that uses a single mast set in the aft half of the hull. The mast supports fore-sails that may consist of a single jib, multiple staysails, or a crab claw sail. The mainsail is either small or completely absent. Mast-aft rigs are uncommon, but are found on a few custom, and production sailboats.

<i>Potosi</i> (barque)

Potosi was a five-masted steel barque built in 1895 by Joh. C. Tecklenborg ship yard in Geestemünde, Germany, for the sailing ship company F. Laeisz as a trading vessel. Its primary purpose was as a "nitrate clipper" collecting guano in South America for use in chemical companies in Germany. As its shipping route was between Germany and Chile, it was designed to be capable of withstanding the rough weather encountered around Cape Horn.

<span class="mw-page-title-main">Lug sail</span> Type of sail

The lug sail, or lugsail, is a fore-and-aft, four-cornered sail that is suspended from a spar, called a yard. When raised, the sail area overlaps the mast. For "standing lug" rigs, the sail may remain on the same side of the mast on both the port and starboard tacks. For "dipping lug" rigs, the sail is lowered partially or totally to be brought around to the leeward side of the mast in order to optimize the efficiency of the sail on both tacks.

<span class="mw-page-title-main">Sail plan</span> Technical drawing of a sailing craft

A sail plan is a drawing of a sailing craft, viewed from the side, depicting its sails, the spars that carry them and some of the rigging that supports the rig. By extension, "sail plan" describes the arrangement of sails on a craft. A sailing craft may be waterborne, an iceboat, or a sail-powered land vehicle.
