Sailing Terms starting with ...

A

Above board On or above the deck, in plain view, not hiding anything. Abaft Toward the stern, relative to some object ("abaft the fore hatch"). Abaft the beam A relative bearing of greater than 90 degrees from the bow. e.g. "two points abaft the port beam." Abandon Ship An imperative to leave the vessel immediately, usually in the face of some imminent danger. Abeam "On the beam", a relative bearing at right angles to the centerline of the ship's keel.

In ascending order of seniority, Rear Admiral, Vice Admiral, Admiral and Admiral of the Fleet (Royal Navy). Derivation reputedly Arabic, from "Emir al Bath" ("Ruler of the waters"). Admiralty law Body of law that deals with maritime cases. In UK administered by the Probate, Divorce and Admiralty Division of the High Court of Justice. Adrift Afloat and unattached in any way to the shore or seabed. It may also imply that a vessel is not anchored and not under control, therefore goes where the wind and current take her, (loose from moorings, or out of place). Also refers to any gear not fastened down or put away properly. It can also be used to mean "absent without leave". Aft Towards the stern (of the vessel). Aground Resting on or touching the ground or bottom. Ahead Forward of the bow. Ahoy A cry to draw attention. Term used to hail a boat or a ship, as "Boat ahoy!".

All hands Entire ship's company, both officers and enlisted personnel. Aloft Above the ship's uppermost solid structure; overhead or high above. Alongside By the side of a ship or pier. Amidships (or midships) In the middle portion of ship, along the line of the keel. Anchor An object designed to prevent or slow the drift of a ship, attached to the ship by a line or chain; typically a metal, hook like, object designed to grip the bottom under the body of water. Anchorage A suitable place for a ship to anchor. Area of a port or harbor. Anchor's aweigh Said of an anchor when just clear of the bottom. Anchor ball Black shape hoisted in forepart of a ship to show that ship is anchored in a fairway. Anchor buoy A small buoy secured by a light line to anchor to indicate position of anchor on bottom. Anchor chain or cable Chain connecting the ship to the anchor. Anchor detail Group of men who handle ground tackle when the ship is anchoring or getting underway. Anchor light White light displayed by a ship at anchor. Two such lights are displayed by a ship over 150 feet (46 m) in length.

Back and fill To use the advantage of the tide being with you when the wind is not. Backstays Long lines or cables, reaching from the rear of the vessel to the mast heads, used to support the mast. Baggywrinkle A soft covering for cables (or any other obstructions) that prevents sail chafing from occurring. Bank (sea floor) A large area of elevated sea floor. Banyan Traditional Royal Navy term for a day or shorter period of rest and relaxation. Bar Large mass of sand or earth, formed by the surge of the sea. They are mostly found at the entrances of great rivers or havens, and often render navigation extremely dangerous, but confer tranquility once inside. See also: Touch and go, grounding. Alfred Lord Tennyson's poem 'Crossing the bar' an allegory for death. Barrelman A sailor that was stationed in the crow's nest. Bar pilot A bar pilot guides ships over the dangerous sandbars at the mouth of rivers and bays. Beacon A lighted or unlighted fixed aid to navigation attached directly to the earth’s surface. (Lights and daybeacons both constitute beacons). Beam The beam of a ship is its width at the widest point, or a point alongside the ship at the mid-point of its length. Beam ends The sides of a ship. "On her beam ends" may mean the vessel is literally on her side and possibly about to capsize; more often, the phrase means the vessel is listing 45 degrees or more. Bear away Turn away from the wind, often with reference to a transit. Bear down Turn away from the wind, often with reference to a transit. Bearing The horizontal direction of a line of sight between two objects on the surface of the earth. Before the mast Literally, the area of a ship before the foremast (the forecastle). Most often used to describe men whose living quarters are located here, officers being housed behind (abaft) the mast and enlisted men before the mast. This was because the midships area where the officers were berthed is more stable, being closer to the center of gravity, and thus more comfortable. It is less subject to the up and down movement resulting from the ship's pitching. Belaying pins Bars of iron or hard wood to which running rigging may be secured, or belayed. Berth A bed on a boat, or a space in a port or harbour where a vessel can be tied up. Best bower (anchor) The larger of two anchors carried in the bow; so named as it was the last, best hope. Bilge The bilge is the compartment at the bottom of the hull of a ship or boat where water collects so that it may be pumped out of the vessel at a later time. Bilged on her anchor A ship that has run upon her own anchor. Bimini Weather-resistant fabric stretched over a stainless steel frame, fastened above the cockpit of a sailboat or flybridge of a power yacht which serves as a rain or sun shade. Bimmy A punitive instrument. Binnacle The stand on which the ship's compass is mounted. Binnacle list A ship's sick list. The list of men unable to report for duty was given to the officer or mate of the watch by the ship's surgeon. The list was kept at the binnacle. Bitt, plural Bitts Posts mounted on the ship's bow, merely comprising two wooden uprights supporting a crossbar, for fastening ropes or cables; also used on various ships to tie boys over for painful (posterior) discipline, more informally than kissing the gunner's daughter. Bitter end The anchor cable is tied to the bitts, when the cable is fully paid out, the bitter end has been reached. The last part of a rope or cable. Bloody An intensive derived from the substantive 'blood', a name applied to the Bucks, Scrowers, and Mohocks of the seventeenth centuries. Blue Peter A blue and white flag hoisted at the foretrucks of ships about to sail. Boat A craft or vessel designed to float on, and provide transport over, water. Boatswain or bosun A non-commissioned officer responsible for the sails, ropes and boats on a ship who issues "piped" commands to seamen. Bollard From "bol" or "bole", the round trunk of a tree. A substantial vertical pillar to which lines may be made fast. Generally on the quayside rather than the ship. Booby A type of bird that has little fear and therefore is particularly easy to catch, hence booby prize. Booby hatch A sliding hatch or cover. Boom A spar used to extend the foot of a for-and-aft sail. Booms Masts or yards, lying on board in reserve. Boom vang (vang) A sail control that lets one apply downward tension on the boom, countering the upward tension provided by the mainsail. The boom vang adds an element of control to mainsail shape when the mainsheet is let out enough that it no longer pulls the boom down. Boom vang tension helps control leech twist, a primary component of sail power. Bottomry Pledging a ship as security in a financial transaction. Buoy A floating object of defined shape and color, which is anchored at a given position and serves as an aid to navigation. Bow The front of a ship. Bow-chaser, chase or chase-piece A long gun with a relatively small bore, placed in the bow-port to fire directly ahead. Used especially while chasing an enemy vessel to damage its sails and rigging. (quoted from A Sea of Words). Bowline A type of knot, producing a strong loop of a fixed size, topologically similar to a sheet bend. Also a rope attached to the side of a sail to pull it towards the bow (for keeping the windward edge of the sail steady). Bowse To pull or hoist. Bowsprit A spar projecting from the bow used as an anchor for the forestay and other rigging. Brail To furl or truss a sail by pulling it in towards the mast, or the ropes used to do so. Brass monkeys or brass monkey weather Very cold weather, origin from the cannon balls being stored on a wheeled platform (monkey) made of brass. If the weather was so cold as to cause cannon balls to fall off the brass monkey due to different shrinkage rates of the dissimilar metals it was termed to be cold enough to freeze the balls off a brass monkey. Bridge A structure above the weather deck, extending the full width of the vessel, which houses a command centre, itself called by association, the bridge. Bring to Cause a ship to be stationary by arranging the sails. Broaching-to A sudden movement in navigation, when the ship, while scudding before the wind, accidentally turns her leeward side to windward, also use to describe the point when water starts to come over the gunwhale due to this turn. Buffer The chief bosun's mate (in the Royal Navy), responsible for discipline. Bulkhead An upright wall within the hull of a ship. Particularly a load bearing wall. Bulwark The extension of the ship's side above the level of the weather deck. Bumboat A private boat selling goods. Bumpkin An iron bar (projecting out-board from a ship's side) to which the lower and topsail brace blocks are sometimes hooked. Chains supporting/stabilising the bowsprit. Buntline One of the lines tied to the bottom of a square sail and used to haul it up to the yard when furling. Bunting Tosser A signalman who prepares and flies flag hoists. Also known in the American Navy as a skivvy waver. Buoyed Up Lifted by a buoy, especially a cable that has been lifted to prevent it from trailing on the bottom. By and Large By means into the wind, while large means with the wind. By and large is used to indicate all possible situations "the ship handles well both by and large". By the board Anything that has gone overboard.

Cabin an enclosed room on a deck or flat. Cabin boy attendant on passengers and crew. Cable A large rope; also a measure of length or distance. Equivalent to (UK) 1/10 nautical mile, approx. 600 feet; (USA) 120 fathoms, 720 feet (219 m); other countries use different values. Canister a type of anti personnel cannon load in which lead balls or other loose metallic items were enclosed in a tin or iron shell. On firing the shell would disintegrate releasing the smaller metal objects. Cape Horn fever The name of the fake illness a malingerer is pretending to suffer from. Capsize When a ship or boat lists too far and rolls over, exposing the keel. On large vessels, this often results in the sinking of the ship. Capstan A huge rotating hub (wheel) mounted vertically and provided with horizontal holes to take up the capstan bars (when manually rotated), used to wind in anchors or other heavy objects; and sometimes to administer flogging over. Captain's daughter The cat o' nine tails, which in principle is only used on board on the captain's (or a court martial's) personal orders. Careening Cause the ship to tilt on its side, usually to clean or repair the hull below the water line. Cat To prepare an anchor, after raising it by lifting it with a tackle to the Cat Head, prior to securing (fishing) it alongside for sea. (An anchor raised to the Cat Head is said to be catted). The Cat o' Nine Tails (see below). A cat-rigged boat or catboat. Catamaran A vessel with two hulls. Catboat A cat-rigged vessel with only one sail, usually on a gaff. Cat o' nine tails A short nine-tailed whip kept by the bosun's mate to flog sailors (and soldiers in the Army). When not in use, the cat was kept in a baize bag, hence the term "cat out of the bag". "Not enough room to swing a cat" also derives from this. Cat Head A beam extending out from the hull used to support an anchor when raised in order to secure or "fish" it. Centreboard A removable keel used to resist leeway. Chafing Wear on line or sail caused by constant rubbing against another surface. Chafing Gear Material applied to a line or spar to prevent or reduce chafing. See Baggywrinkle. Chain shot Cannon balls linked with chain used to damage rigging and masts. Chain-wale or channel A broad, thick plank that projects horizontally from each of a ship's sides abreast a mast, distinguished as the fore, main, or mizzen channel accordingly, serving to extend the base for the shrouds, which supports the mast. Chase guns Cannons mounted on the bow or stern. Those on the bow could be used to fire upon a ship ahead, while those on the rear could be used to ward off pursuing vessels. Chine A relatively sharp angle in the hull, as compared to the rounded bottoms of most traditional boat hulls. Chock-a-block Rigging blocks that are so tight against one another that they cannot be further tightened. Civil Red Ensign The British Naval Ensign or Flag of the British Merchant Navy, a red flag with the Union Flag in the upper left corner. Clean bill of health A certificate issued by a port indicating that the ship carries no infectious diseases. Clean slate At the helm, the watch keeper would record details of speed, distances, headings, etc. on a slate. At the beginning of a new watch the slate would be wiped clean. Cleat A stationary device used to secure a rope aboard a vessel. Clew-lines Used to truss up the clews, the lower corners of square sails. Club hauling The ship drops one of its anchors at high speed to turn abruptly. This was sometimes used as a means to get a good firing angle on a pursuing vessel. Coaming The raised edge of a hatchway used to help keep out water. Companionway A raised and windowed hatchway in the ship's deck, with a ladder leading below and the hooded entrance-hatch to the main cabins. Compass Navigational instrument that revolutionised travel. Corrector a device to correct the ship's compass. Courses The mainsail, foresail, and the mizzen. Coxswain or cockswain The helmsman or crew member in command of a boat. As the crow flies A direct line between two points (which might cross land) which is the way crows travel rather than ships which must go around land. Crow's nest Specifically a masthead constructed with sides and sometimes a roof to shelter the lookouts from the weather, generally by whaling vessels, this term has become a generic term for what is properly called masthead. See masthead. Cuddy A small cabin in a boat. Cunningham A line invented by Briggs Cunningham, used to control the shape of a sail. Cut splice A join between two lines, similar to an eye-splice, where each rope end is joined to the other a short distance along, making an opening which closes under tension. Cutline The "valley" between the strands of a rope or cable. Cut and run When wanting to make a quick escape, a ship might cut lashings to sails or cables for anchors, causing damage to the rigging, or losing an anchor, but shortening the time needed to make ready by bypassing the proper procedures. Cut of his jib The "cut" of a sail refers to its shape. Since this would vary between ships, it could be used both to identify a familiar vessel at a distance, and to judge the possible sailing qualities of an unknown one.

Daggerboard A type of centerboard that is removed vertically. Davy Jones (Locker) An idiom for the bottom of the sea. Daybeacon An unlighted fixed structure which is equipped with a dayboard for daytime identification. Dayboard The daytime identifier of an aid to navigation presenting one of several standard shapes (square, triangle, rectangle) and colors (red, green, white, orange, yellow, or black). Deadeye A round wooden plank which serves a similar purpose to a block in the standing rigging of large sailing vessels. Deadrise The design angle between the keel (q.v.) and horizontal. Decks the structures forming the approximately horizontal surfaces in the ship's general structure. Unlike flats, they are a structural part of the ship. Deck hand A person whose job involves aiding the deck supervisor in (un)mooring, anchoring, maintenance, and general evolutions on deck. Deck supervisor The person in charge of all evolutions and maintenance on deck; sometimes split into two groups: forward deck supervisor, aft deck supervisor. Deckhead The under-side of the deck above. Sometimes paneled over to hide the pipe work. This paneling, like that lining the bottom and sides of the holds, is the ceiling. Derrick A lifting device composed of one mast or pole and a boom or jib which is hinged freely at the bottom. Devil seam The curved seam in the hull planking closest to the waterline when the ship is level. The seam between these two planks, set at a nominal right angle to each other, is the devil seam. This seam is particularly difficult to pay (and caulk) because there is little support in the direction of the compression created during caulking and expansion of the wood when wet. Hence, this seam "works" a lot. A sailor sealing this seam must first cause the ship to list (lean) toward the side opposite of the seam. This allows the sailor access to the seam by hanging below it, "between the Devil and the deep blue sea". Devil to pay (or Devil to pay, and no pitch hot) "Paying" the Devil is sealing the devil seam. It is a difficult and unpleasant job (with no resources) because of the shape of the seam (closest to the waterline) and because you are positioned below the natural waterline. Directional light A light illuminating a sector or very narrow angle and intended to mark a direction to be followed. Disrate To reduce in rank or rating; demote. Dog watch A short watch period, generally half the usual time (e.g. a two hour watch between two four hour ones). Such a watch might be included in order to slowly rotate the system over several days for fairness, or to allow both watches to eat their meals at approximately normal times. Dolphin A structure consisting of a number of piles driven into the seabed or riverbed in a circular pattern and drawn together with wire rope. Downhaul A line used to control either a mobile spar, or the shape of a sail. Draft The depth of a ship's keel below the waterline. Draught See draft. Dressing down Treating old sails with oil or wax to renew them, or a verbal reprimand. Driver The large sail flown from the mizzen gaff. Driver-mast The fifth mast of a six-masted barquentine or gaff schooner. It is preceded by the jigger mast and followed by the spanker mast. The sixth mast of the only seven-masted vessel, the gaff schooner Thomas W. Lawson, was normally called the pusher-mast. Dunnage Loose packing material used to protect a ship's cargo from damage during transport. Personal baggage.

Earrings Small lines, by which the uppermost corners of the largest sails are secured to the yardarms. Embayed The condition where a sailing vessel is confined between two capes or headlands, typically where the wind is blowing directly onshore. Extremis (also known as “in extremis”) The point under International Rules of the Road (Navigation Rules) at which the privileged (or stand-on) vessel on collision course with a burdened (or give-way) vessel determines it must maneuver to avoid a collision. Prior to extremis, the privileged vessel must maintain course and speed and the burdened vessel must maneuver to avoid collision.

F - [Back to top]

Fathom A unit of length equal to 6 feet (1.8 m), roughly measured as the distance between a man's outstretched hands. Fender An air or foam filled bumper used in boating to keep boats from banging into docks or each other. Figurehead Symbolic image at the head of a traditional sailing ship or early steamer. Fireship A ship loaded with flammable materials and explosives and sailed into an enemy port or fleet either already burning or ready to be set alight by its crew (who would then abandon it) in order to collide with and set fire to enemy ships. First rate The classification for the largest sailing warships of the 17th through 19th centuries. They had 3 masts, 850+ crew and 100+ guns. Fish To repair a mast or spar with a fillet of wood. To secure an anchor on the side of the ship for sea (otherwise known as "catting".) First Lieutenant In the Royal Navy, the senior lieutenant on board; responsible to the Commander for the domestic affairs of the ship's company. Also known as 'Jimmy the One' or 'Number One'. Removes his cap when visiting the mess decks as token of respect for the privacy of the crew in those quarters. Officer i/c cables on the forecastle. In the U.S. Navy the senior person in charge of all Deck hands. First Mate The Second in command of a ship. Flag hoist A number of signal flags strung together to convey a message, e.g. "England expects...". Flank The maximum speed of a ship. Faster than "full speed". Flatback A Great Lakes slang term for a vessel without any self unloading equipment. Flemish Coil A line coiled around itself to neaten the decks or dock. Flog To beat, to punish. Fluke The wedge-shaped part of an anchor's arms that digs into the bottom. Fly by night A large sail used only for sailing downwind, requiring little attention. Following sea Wave or tidal movement going in the same direction as a ship. Foot The bottom of a sail. Footloose If the foot of a sail is not secured properly, it is footloose, blowing around in the wind. Footrope Each yard on a square rigged sailing ship is equipped with a footrope for sailors to stand on while setting or stowing the sails. Forecastle A partial deck, above the upper deck and at the head of the vessel; traditionally the sailors living quarters. Pronounced "focsle". The name is derived from the castle fitted to bear archers in time of war. Founder To fill with water and sink → Wiktionary. Fore Towards the bow (of the vessel). Forefoot The lower part of the stem of a ship. Foremast jack An enlisted sailor, one who is housed before the foremast. Forestays Long lines or cables, reaching from the front of the vessel to the mast heads, used to support the mast. Freeboard The height of a ship's hull (excluding superstructure) above the waterline. The vertical distance from the current waterline to the lowest point on the highest continuous watertight deck. This usually varies from one part to another. Full and by Sailing into the wind (by), but not as close-hauled as might be possible, so as to make sure the sails are kept full. This provides a margin for error to avoid being taken aback (a serious risk for square-rigged vessels) in a tricky sea. Figuratively it implies getting on with the job but in a steady, relaxed way, without undue urgency or strain. Furl To roll or wrap a sail around the mast or spar to which it is attached.

G - [Back to top]

Gaff The spar that holds the upper edge of a fore-and-aft or gaff sail. Also a long hook with a sharp point to haul fish in. Galley The kitchen of the ship. Gangplank A movable bridge used in boarding or leaving a ship at a pier; also known as a "brow". Garbled Garbling was the (illegal) practice of mixing cargo with garbage. Garboard The strake closest to the keel (from Dutch gaarboard). Global Positioning System (GPS) A satellite based radionavigation system providing continuous worldwide coverage. It provides navigation, position, and timing information to air, marine, and land users. Grapeshot Small balls of lead fired from a cannon, similar to shotgun shot on a larger scale. Used to hurt people, rather than cause structural damage. Grog Watered-down pusser's rum consisting of half a gill with equal part of water, issued to all seamen over twenty. (CPOs and POs were issued with neat rum) From the British Admiral Vernon who, in 1740, ordered the men's ration of rum to be watered down. He was called "Old Grogram" because he often wore a grogram coat), and the watered rum came to be called 'grog'. Often used (illegally) as currency in exchange for favours in quantities prescribed as 'sippers' and 'gulpers'. Additional issues of grog were made on the command 'splice the mainbrace' for celebrations or as a reward for performing especially onerous duties. The RN discontinued the practice of issuing rum in 1970. A sailor might repay a colleague for a favour by giving him part or all of his grog ration, ranging from "sippers" (a small amount) via "gulpers" (a larger quantity) to "grounders" (the entire tot). Groggy Drunk from having consumed a lot of grog. Gunner's daughter See Kissing the G.'s D. Gunwhale Upper edge of the hull.

Halyard or Halliard Originally, ropes used for hoisting a spar with a sail attached; today, a line used to raise the head of any sail. Hammock Canvas sheets, slung from the deckhead in messdecks, in which seamen slept. "Lash up and stow" a piped command to tie up hammocks and stow them (typically) in racks inboard of the ship's side to protect crew from splinters from shot and provide a ready means of preventing flooding caused by damage. Hand Bomber A ship using coal-fired boilers shoveled in by hand. Hand over fist To climb steadily upwards, from the motion of a sailor climbing shrouds on a sailing ship (originally "hand over hand"). Handsomely With a slow even motion, as when hauling on a line "handsomely." Hank A fastener attached to the luff of the headsail that attaches the headsail to the forestay. Typical designs include a bronze or plastic hook with a spring-operated gate, or a strip of cloth webbing with a snap fastener. Harbor A harbor or harbour, or haven, is a place where ships may shelter from the weather or are stored. Harbours can be man-made or natural. Haul wind To point the ship so as to be heading in the same direction as the wind, generally not the fastest point of travel on a sailing vessel. Hawse-hole A hole in a ship's bow for a cable or chain, such as for an anchor, to pass through. Hawsepiper An informal maritime industry term used to refer to a merchant ship’s officer who began his or her career as an unlicensed merchant seaman and did not attend a traditional maritime college/academy to earn the officer license. Head The toilet or latrine of a vessel, which for sailing ships projected from the bows. Head of navigation A term used to describe the farthest point above the mouth of a river that can be navigated by ships. Headsail Any sail flown in front of the most forward mast. Heave A vessel's transient up-and-down motion. Heaving to To stop a sailing vessel by lashing the helm in opposition to the sails. The vessel will gradually drift to leeward, the speed of the drift depending on the vessel's design. Heave down Turn a ship on its side (for cleaning). Heeling Heeling is the lean caused by the wind's force on the sails of a sailing vessel. Helmsman A person who steers a ship. Hogging or hog The distortion of the hull where the ends of the keel are lower than the center. Hold In earlier use, below the orlop deck, the lower part of the interior of a ship's hull, especially when considered as storage space, as for cargo. In later merchant vessels it extended up through the decks to the underside of the weather deck. Holiday A gap in the coverage of newly applied paint, slush, tar or other preservative. Holystone A chunk of sandstone used to scrub the decks. The name comes from both the kneeling position sailors adopt to scrub the deck (reminiscent of genuflection for prayer), and the stone itself (which resembled a Bible in shape and size). Horn A sound signal which uses electricity or compressed air to vibrate a disc diaphragm. Horse Attachment of sheets to deck of vessel (Main-sheet horse). Hounds Attachments of stays to masts. Hull The shell and framework of the basic flotation-oriented part of a ship. Hydrofoil A boat with wing-like foils mounted on struts below the hull.

I - [Back to top]

Icing A serious hazard where cold temperatures (below about -10°C) combined with high wind speed (typically force 8 or above on the Beaufort scale) result in spray blown off the sea freezing immediately on contact with the ship. Idlers Members of a ship's company not required to serve watches. These were in general specialist tradesmen such as the carpenter and the sailmaker. In Irons When the bow of a sailboat is headed into the wind and the boat has stalled and is unable to maneuver. In the offing In the water visible from on board a ship, now used to mean something imminent. Inboard-Outboard drive system A larger Power Boating alternative drive system to transom mounted outboard motors.

J - [Back to top]

Jack Either a flag, or a sailor. Typically the flag was talked about as if it were a member of the crew. Strictly speaking, a flag is only a "jack" if it is worn at the jackstaff at the bow of a ship. Jacklines or Jack Stays Lines, often steel wire with a plastic jacket, from the bow to the stern on both port and starboard. The Jack Lines are used to clip on the safety harness to secure the crew to the vessel while giving them the freedom to walk on the deck. Jack Tar A sailor dressed in 'square rig' with square collar. Formerly with a tarred pigtail. Jib A triangular staysail at the front of a ship. Jigger-mast The fourth mast, although ships with four or more masts were uncommon, or the aft most mast where it is smallest on vessels of less than four masts. Jollies Traditional Royal Navy nickname for the Royal Marines. Junk Old cordage past its useful service life as lines aboard ship. The strands of old junk were teased apart in the process called picking oakum.

K - [Back to top]

Killick A small anchor. A fouled killick is the substantive badge of non-commissioned officers in the RN. Seamen promoted to the first step in the promotion ladder are called "Killick". The badge signifies that here is an Able Seaman skilled to cope with the awkward job of dealing with a fouled anchor. Keel The central structural basis of the hull. Keelhauling Maritime punishment: to punish by dragging under the keel of a ship. Kelson The timber immediately above the keel of a wooden ship. Kissing the gunner's daughter bend over the barrel of a gun for punitive spanking with a cane or cat. Know the ropes A sailor who 'knows the ropes' is familiar with the miles of cordage and ropes involved in running a ship.

L - [Back to top]

Ladder On board a ship, all "stairs" are called ladders, except for literal staircases aboard passenger ships. Most "stairs" on a ship are narrow and nearly vertical, hence the name. Believed to be from the Anglo-Saxon word hiaeder, meaning ladder. Laker Great Lakes slang for a vessel who spends all its time on the 5 Great Lakes. Land lubber A person unfamiliar with being on the sea. Lanyard A rope that ties something off. Larboard The left side of the ship (archaic, see port). cf. starboard. Derived from the old 'lay-board' providing access between a ship and a quay. Large See By and large. Lateral System A system of aids to navigation in which characteristics of buoys and beacons indicate the sides of the channel or route relative to a conventional direction of buoyage (usually upstream). Lay To come and go, used in giving orders to the crew, such as "lay forward" or "lay aloft". To direct the course of vessel. Also, to twist the strands of a rope together. Lay down To lay a ship down is to begin construction in a shipyard. League A unit of length, normally equal to three nautical miles. Leech The aft or trailing edge of a fore-and-aft sail; the leeward edge of a spinnaker; a vertical edge of a square sail. The leech is susceptible to twist, which is controlled by the boom vang and mainsheet. Leehelm If the helm was centered, the boat would turn away from the wind (to the lee). Consequently, the tiller must be pushed to the lee side of the boat in order to make the boat sail in a straight line. See weatherhelm. Lee side The side of a ship sheltered from the wind (opposite the weather side or windward side). Lee shore A shore downwind of a ship. A ship which cannot sail well to windward risks being blown onto a lee shore and grounded. Leeway The angle that a ship is blown leeward by the wind. See also weatherly. Leeward In the direction that the wind is blowing towards. Let go and haul An order indicating that the ship is in line with the wind. Letter of marque and reprisal A warrant granted to a privateer condoning specific acts of piracy against a target as a redress for grievances. Lifeboat A small steel or wood boat located near the stern of a vessel. Used to get the crew to safety if something happens to the mothership. Line The correct nautical term for the majority of the cordage or "ropes" used on a vessel. A line will always have a more specific name, such as mizzen topsail halyard, which describes its use. Liner Ship of The Line: a major warship capable of taking its place in the main (battle) line of fighting ships. Hence modern term for most prestigious passenger vessel: Liner.

Food in the Royal Navy was invariably better or at least in greater quantity than that available to the average landsman. However, while square wooden plates were indeed used on board ship, there is no established link between them and this particular term. The OED gives the earliest reference from the U.S. in the mid 19th century. Squared away Yards held rigidly perpendicular to their masts and parallel to the deck. This was rarely the best trim of the yards for efficiency but made a pretty sight for inspections and in harbor. The term is applied to situations and to people figuratively to mean that all difficulties have been resolved or that the person is performing well and is mentally and physically prepared. Squat effect Is the phenomenon by which a vessel moving quickly through shallow water creates an area of lowered pressure under its keel that reduces the ship's buoyancy, particularly at the bow. The reduced buoyancy causes the ship to "squat" lower in the water than would ordinarily be expected. Standing rigging Rigging which is used to support masts and spars, and is not normally manipulated during normal operations. Cf. running rigging.
