Back -To back a sail, is to haul the sheet to windward.
Back and Fill - To luff up in the wind, and then fill off again. Often a vessel is worked up a narrow channel with a weather tide by backing and filling: that is, the helm is put down slowly, and the vessel kept moving until she is nearly head to wind; the helm is then put smartly up, and the vessel filled again. Care must be always taken to fill before the vessel loses way. Figuratively, to back and fill is to blow hot and cold, or assent and dissent, or to go backwards and forwards with opinions.
Backing - Timber fitted at the back of other timbers.
Backstay - A wire support for the mast, usually running from the stern to the head of the mast.The stays that support the topmast with a beam or stern wind. The topmast shrouds or rigging. (See "Shifting Backstay" and "Preventer.")
Backwater - The water thrown back when waves strike a wall or other solid object. The water that appears to follow under the stern of a ship. To back water is to move the oars of a boat so that the boat moves astern instead of ahead.
Baffling Wind - A wind that is continually shifting its direction, so that it is difficult to keep the sails full or steady; more frequently used when the vessel is close or nearly close hauled.
Bag - Sails are said to bag when they do not sit flat.
Baggywrinkle - Clumps of frayed rope that protect the sails from charing against the lines.
Bagpipe - To bring the sheet of an after-sail, such as the mizen, forward to the weather rigging, so that the sail forms a bag, or back sail: when head to wind useful to put stern way on a vessel.
Balance Lug - A lug sail with a boom and yard. About one-twelfth of the sail is on the fore side of the mast, and thus "balances" on the mast, requiring no dipping when going about; apparently adapted from the Chinese lug sail.
Balance Reef - In gaff sails a hand with reef points or eyelet holes for lacing, sewn from the throat to the clew. The reef is taken in by lowering the jaws down to the boom and lacing the sail along the reef band to the boom. Sometimes the gaff end is lowered down to the boom end; in which case the reef band is laced along the gaff.
Bail - To throw water out of a vessel or boat by buckets or balers.
Bailer - A small basin-like vessel, used for throwing water out of a boat.
Bale - A fitting on the end of a spar, such as the boom, to which a line may be led.
Ballast - usually metal, placed low in a boat to provide stability. Dead weight carried to assist the stability of a vessel. A ship is said to be in ballast when she has no merchandise on board, but only sand, gravel, mud, or rubbish as ballast. A yacht in marine parlance is always "in ballast."
Ballast, To Keep Clean or Sweeten -
The ballast of an old vessel should be removed every other season, scrubbed, and whitewashed with hot lime, or coated with black varnish, paraffin, or red lead. The hold of the yacht should at the same time be thoroughly cleansed and black varnished, distempered, or red leaded, or coated with one of the patent paints. A mixture of two-thirds Stockholm tar and one-third coal tar boiled together will make a good composition for the ballast and the inside of a vessel below the floor. Many vessels are regularly hauled up every year, and of course their ballast is taken out and stored. The ballast of a new vessel generally requires cleansing when she is laid up, as the soakings from the oak frames make a very unpleasant odour. (See "Distemper," "Laying Up," and "Limber Boards").
Ballast Bearers. (See "Bearers.")
Ballast, Shifting - To put ballast (usually duck shot in bags) in the weather side of a vessel during sailing.
Balloon Sails - Balloon canvas is a term applied to sails of large dimensions, made of light cotton canvas. The chief balloon sail is the spinnaker used for sailing when the wind is aft. A balloon jib used to fill up the whole space from the bowsprit end, masthead, and mast at deck; a balloon foresail is hanked to the forestay, but the clew extends some distance abaft the mast; in a schooner a balloon maintopmast staysail has an up and down weather leech extending below the lower corner of the sail, which is hanked to the maintopmast stay. It is sheeted on to the end of the main boom. A balloon jib topsail or "Yankee" jib topsail is a useful sail ; all modern balloon head sails are cut very high in the clew, so that the lead of the sheet nearly makes a right angle with the luff of the sail. Balloon jibs have long gone out of fashion. They were succeeded by "bowsprit spinnakers," whilst the bowsprit spinnaker, a low-footed sail, has in turn given place to the higher clewed balloon jib topsail A balloon topsail is another name for a jackyard topsail, or a topsail set with two yards. The upper or "topsail yard" is a vertical continuation of the topmast. The "lower" yard or jackyard is parallel with the gaff and should act as a direct continuation or extension of it. In setting a jackyard topsail a certain amount of "drift" or "space" should be left between the gaff and the lower yard so that there may be play to take up the slack of the sheet.
A jackyard topsail should set as flat as a card. Formerly, the foot yard was short and the head yard was of great length -- as long as could be stowed on the deck of a yacht -- and the sail, very heavy to hoist, was quite unfit for close-hauled work. As the hoisting of these heavy yards was an operation of so much labour, they fell into disuse for some years between 1873 and 1888. After that date the sail was reintroduced with a comparatively short head yard and longer foot yard, after a pattern designed in American waters. The sail had consequently as much area as the old fashioned "balloon topsail," and the combined weight of head yard and foot yard was about half that of the old yard; beyond this, as the sail was well peaked, it sits and stands well on a wind in moderate breezes. In the present century with the introduction of hollow yards the area of the sail has been further increased, and the extreme lightness of yards has enabled the balloon topsail to be carried efficiently in fresh and even strong winds.
Bamboo Spars - In small boats these are often used on account of their lightness. They vary much in strength, and should be from 10 to 20 percent greater diameter than solid wood spars.
Barber Hauler - A line attached to the jib or jib sheet, used to adjust the angle of sheeting by pulling the sheet toward the centerline of the boat.
Bare Poles - With no sail set. With all the sails furled or stowed at sea for scudding before a heavy gale, or sometimes for lying to.
Bargee - A slang term for the crew of a barge.

Barra Boats - Vessels of the Western Isles of Scotland, with almost perfect V section.
Barrel or Drums - The part of a capstan, windlass, or winch round which the cable or rope is wound whilst heaving. Sometimes termed the drum.
Base Line - In naval architecture a level line near the keel, from which all heights are measured perpendicularly to it. Generally in yacht designs the load waterline, as shown so a Sheer Plan, is made the base line, and all depths arid heights are measured perpendicularly or at right angles to it.
Batten Down - Secure hatches and loose objects both within the hull and on deck. Also putting tarpaulins over hatches or skylights, and securing them by iron bars or wood battens.
Battens - Flexible strips of wood or plastic, most commonly used in the mainsail to support the aft portion, or roach, so that it will not curl. OR A long piece of wood need to lash to yards or booms to strengthen them. Thin pieces of hard wood fitted to spars to prevent their being chafed or cut. Thin splines of wood used by draughtsmen to make curved lines. A general term for a thin strip of wood. Battens are fitted to sails to keep the leach flat.

Beach Boats.-- Flat floored boats that can be readily beached.
Beacon - A stake, boom, or post put on a sandbank or shoal as a warning for vessels.
Beacon Buoy - A buoy with a cross, ball, or triangle, &c., on the top.
Beam - The greatest width of the boat. OR A timber that crosses a vessel transversely to support the deck. The breadth of a vessel. "Before the beam" is forward of the middle part of a ship. The wind is said to be before the beam when the ship makes a less angle than 90û with the wind. A beam wind is a wind that blows at right angles to a vessel's keel. "Abaft the beam "is towards the stern.
Beam and Length - The proportion a vessel's beam bears to her length varies according to her type. In sailing yachts it is found that for cruising a good proportion is about three and a-quarter to three and a half beams to waterline length.
Beam Ends - A vessel is said to be on her beam ends when she is hove down on her side by the wind or other force, so that the ends of her deck beams are on the water, or her deck beams perpendicular to the water. However, in sea parlance, a ship is said to be on her beam ends when knocked down by a squall to say 45û, so that when a ship is described as being on her "beam ends" the meaning need not be taken literally.
Beam Trawl - A trawl whose mouth is extended by a long spar or beam, as distinct from the otter trawl, which is distended by boards.
Bear, To - The direction an object takes from a ship expressed in compass points or by points in the vessel; as in reference to another vessel she bears S.E. or W.S.W., &c., or on the port bow, or weather bow, port beam or weather beam, port quarter or weather quarter; or two points on the weather bow or port bow.
Bear a Hand There! -- An admonition to hurry.
Bear Away, or Bear Up - To put the helm to windward and keep the vessel more off the wind. Generally used in close-hauled sailing when a vessel begins to alter her course by sailing off the wind. (See "Wear.")
Bearers - The beams which carry the cabin floor or platform of a yacht, termed platform bearers.
Bearing - The direction of an object expressed either as a true bearing as shown on the chart, or as a bearing relative to the heading of the boat.
The direction between one object and another; generally the direction of an object on land to a ship. The widest part of a vessel which may either be above or below water. A vessel is said to be on her bearings when she is heeled over, so that her greatest breadth is in the water
Bearings by Compass - An object is said to bear, so many points on the port or starboard bow, or port or starboard quarter, or port or starboard beam as the case may be; or an object may be said to bear E.N.E. or E. or W., from the point of observation. The usual plan of taking a bearing is to stand directly over the binnacle, and notice which point on the compass card directly points to the object. A more accurate way of taking bearings may be followed thus on each quarter-rail abreast of the binnacle, have a half compass plate of brass fixed, or mark off compass points on the rail, and let two opposite points (say north and south) be in direct line or parallel with the keel. A pointer or hand, eight or nine inches long, must be fitted to the plate, to ship and unship on a pivot; move tire pointer until it points directly to the object, then read off the number of points it is from the direction of the ship's head. Next observe the direction of the ship's head by the binnacle compass ; if the ship's head points N., and the pointer showed the object to be, say, four points away westerly from the direction of the ship's head, then the object will bear N.W., and so on. If very great accuracy be required, and if the ship be yawing about, one hand should watch the binnacle compass, whilst another makes the observations with the pointer.
Bear On The Bow -An object is said to bear "on the bow" if its direction in relation to the ship does not make a greater angle with the keel of the vessel than 45û. If the direction of the object makes a greater angle than that it would be said to bear "before the beam" ; next on the beam, then abaft the beam, on the quarter, right astern.
Beat - To beat to windward is to make way against the wind by a zigzag course, and frequent tacking. (See "Plying," "Thrashing," and "Turning to Windward.")

Beef - Manual strength; generally the weight of the men hauling on a rope. "More beef here" is a request for help when hauling. Probably the term originated with the casks of beef used for food on shipboard.
Before the Beam - Towards the bow or stem of a vessel.
Before the Mast - A term used to describe the station of seamen as distinguished from officers. Thus a man before the mast means a common sailor, and not an officer. The term owes its origin to the fact that the seamen were berthed in the forecastle, which is usually "before the mast."
Before the Wind - Running with the wind astern.
Behaviour - The performance of a ship in a seaway or under canvas is generally termed by sailors her "behaviour."
Belay That - An order given whilst men are hauling on a rope, &c., to cease hauling and make fast to the last inch they have got in. Also slang for cease talking or fooling.
Belay, To - To make fast a rope or fall of a tackle. In hauling upon a rope the signal to cease is usually, "Belay!" or "Belay there!" "Belay that !" or "Avast hauling ! Belay!"

Bilgeboards - are on either side of the centerline at the bilges.
Binnacle - A support for the compass, raising it to a convenient position.
Bitter End - The last part of a rope or chain.The inboard end of the anchor rode.
Boat - A fairly indefinite term. A waterborne vehicle smaller than a ship. One definition is a small craft carried aboard a ship. A submarine is always a boat no matter what length.
Board - In beating to windward a board is the time a vessel is on one tack and the distance she makes on that tack. Thus it may be a long board or a short board. Working to windward by a long board and a short board is when a vessel can more nearly lie her course on one tack than on another. Thus, suppose the wind be S.W., and the vessel's course from headland to headland S.S.W., and the vessel can lie four points from the wind; then on the starboard tack the vessel will head S., or two points off her course ; on the port tack she will lie W., or six points off her course. The long board will be the one on the starboard tack. A vessel is said to make a good board when the wind frees her on one tack; a bad board when it heads her. A stern board is to get stern way on whilst tacking.
Board, To - To board a ship is to enter upon her deck, generally supposed to mean without invitation.
"By the board" - To fall close by the deck. A mast is said to go by the board when it breaks by the deck and falls overboard.

Boat Hook - A short shaft with a fitting at one end shaped to facilitate use in putting a line over a piling, recovering an object dropped overboard, or in pushing or fending off. A wood pole with a metal hook and prong at one end; sometimes with two hooks. A yacht's gig has two boat hooks-one for the use of the bowman, another for the stroke; by these means a boat is held alongside the stops of a jetty or by the gangway of a vessel
Boat Keeper - The man left in charge of a boat when the other part of her crew go on shore.
Boat's Crew - Men told off to always man a particular boat, such as the gig, cutter, or dinghy of a yacht.
Boatswain - An officer who takes charge of a yacht's gear, and it is his duty to superintend all work done upon the spars, rigging, or sails. He also takes charge of all spare gear and sails, and sees that everything on deck and above deck is neat, clear, and ship-shape. He must in every sense of the word be a thorough seaman, and must know how all work upon rigging and sails should be done. As he has constantly to handle the sails and rigging, he necessarily has a knowledge of their condition, and it is his duty to report all defects in the same.
Boatswain's Call - A whistle consisting of a hollow ball and a tube leading to a hole in it. By varying the sounds the men are "piped" to their work just the same as soldiers are ordered by the sound of a bugle. The pipe is seldom met with in English yachts, except in some of large size, and the boatswain has little to do with giving orders.
Bobstay - Wire Stay underneath the bowsprit; helps to counteract the upward pull exerted by the forestay.
Body - Part of a vessel's hull, as fore-body, middle-body, and after-body. A vessel is said to be long-bodied when the fullness is carried well towards the ends ; short-bodied when the fore-and-aft lines taper very suddenly; a long-body thus means a great parallel length of middle-body. (See "Straight of Breadth.")
Body Plan - A plan which contains the cross sections of a vessel. The midship section or largest section is generally shown on the right-hand side of the middle line of the body plan; sometimes on both sides.
Bollard - A stout timber to fasten ropes and warps to.
Bollard Timbers - The bollard timbers of a vessel are the same as the knightheads; originally the knightheads were carved figures of knights (fitted near the foremast to receive the windlass), hence the name knightheads. (See "Knightheads.")
Bollock Blocks - Two blocks in the middle of a topsail yard of square rigged vessel, used in hoisting.
Bolsters - Pieces of hard wood bolted to the yoke or lower cap on the mast for the rigging to rest upon. They are sometimes covered with leather or sheepskin with the hair on, or raw hide, to prevent the rigging chafing. (See "Rigging Plans.")
Bolt - A fastening of metal. An eye bolt is a bolt with an eye in it used to hook blocks to. A ring bolt is a bolt with an eye and a ring in the eye. An ear bolt or lug bolt is a bolt with a kind of slot in it to receive the part of another bolt, a pin keeping the two together and forming a kind of joint. Bay bolts are bolts with jagged edges to prevent their drawing. A bolt applies to a roll of canvas.
Bolt Rope - The rope sewn round the edges of sails. It is made of the very best quality hemp, dressed with Stockholm tar. A fore-and-aft sail is roped on port side, a squaresail on aft side. There is the weather (luff) rope, leech rope, toot rope, and head rope. Steel wire is used for the luff ropes of all racing sails.
Booby Hatch - A hatch on coamings used to give greater height in the cabin of small yachts, and which can be removed. It is also called a "coach roof."
Boom Crutch - Support for the boom, holding it up and out of the way when the boat is anchored or moored. Unlike a gallows frame, a crutch is stowed when boat is sailing.
Boom - free swinging spar attached to the foot of the sail with forward end pivoting on the mast. A spar used to extend the foot of sails. To top the boom is to make sail and away. To boom off is to shove off a wharf, bank, &c., by the aid of spars. Stakes of wood used to denote a channel through shoal water are termed booms.
Boom Crutch - Support for the boom, holding it up and out of the way when the boat is anchored or moored. Unlike a gallows frame, a crutch is stowed when boat is sailing.
Boom Irons - Iron bands on square yards, with eyes, in which studding sail booms travel.
Boomkin - A short boom of great strength, usually written "bumpkin."
Boom Vang - A system used to hold the boom down, particularly when boat is sailing downwind, so that the mainsail area facing the wind is kept to a maximum. Frequently extends from the boom to a location near the base of the mast. Usually tackle- or lever-operated.
Boomkin (bumpkin)- Short spar extending aft from the transom. Used to anchor the backstay or the sheets from the mizzen on a yawl or ketch.
Boot Top - A painted stripe that indicates the waterline.
Bore - A sudden tide wave, which rolls along rapidly at certain times on some rivers, and makes a great noise.
Boreas - The north wind. An old sailor's saying is, "as cold as Boreas with an iceberg in each pocket." Popularly the god that rules the wind, as Aeolus is supposed to do.
Bore Away - Did bear away. Said of a vessel that alters her course in a leewardly direction, as "she bore away."
Bore by the Head - A vessel is said to bore by the head when she, whilst passing through the water, is depressed by the bead.

Bottomry - The hull or bottom of a ship pledged as security for a loan. If the ship be lost the money is lost unless the lender has covered himself by other means.
Bound - Encased with metal bands. Also referring to the destination of a vessel. Wind-bound means that a vessel is in a port or at an anchorage because the wind is unfavourable for her to proceed. Formerly square-rigged ships were everlastingly windbound, i.e., waiting in port because the wind was adverse; now they go out and look for a fair wind, and generally can sail so well on a wind that waiting for a fair wind would be considered an unpardonable piece of folly.
Bow - The forward part of a boat.The fore part of a vessel ; forward of the greatest transverse section. In taking bearings an object is said to be on the bow if its direction does not make more than an angle of 45û with the line of the keel.
Bower Anchor - The anchor in constant use.
Bow Fast - A warp for holding the vessel by the bow.
Bowing the Sea - Meeting the sea bow on or end on, or nearly end on, as in close-hauled sailing. When the sea runs the with the wind.
Bowline - Knot used to form a temporary loop in a line
BowLine - Ropes made fast to cringles in the weather leech of square sails, to pull them taut and steady when sailing on a wind. The bow lines usually lead into a bridle. Sailing on a bow line means sailing on a wind when the bow lines would be hauled taut; hence the phrase "sailing on a taut bowline." Sailing on an easy bow line means sailing with the sails well full, and the bow lines eased up a little, so that the vessel is not quite "on a wind" or close hauled.
Bow Line - A docking line leading from the bow.
Bow-lines - Continuation of buttock lines, showing the outline of vertical fore-and-aft sections in the forebody. Generally the whole line is termed a buttock line.
Bowsing.-- Hauling with a will upon a rope.
Bowsprit - A short spar extending forward from the bow. Normally used to anchor the forestay. A running bowsprit is one that can easily be reefed in like a cutter's. Sometimes when a bowsprit is reefed in by the fids it is wrongly said to be housed; a bowsprit is housed when run close in to the cranse iron. A standing bowsprit is one fitted in a shoe.
Bowsprit Bitts - Timbers fitted into carlines on the deck to take the bowsprit.
Bowsprit Cranse - The metal cap at the bowsprit end, to which the gear is spliced or shackled.
Bowsprit Shrouds. The horizontal stays from the bowsprit to the sides of the vessel.

Braces - Metal straps fitted round the main piece of rudder or rudder-post and fastened to the sternpost. -- Strengthening pieces of iron or wood to bind together weak places in a vessel. -- Ropes need in working the yards of a ship.
Brace-up and Haul Aft! - The order to trim sails after a vessel has been hove to with sails slack.
Brails - Ropes fast to the leeches of fore-and-aft sails and leading through blocks on the mast hoops. ; need to haul or truss the sail up to the mast instead of lowering it and stowing it. Partially furling sails to lessen wind resistance or partially unfurling sails to make them ready for instant use. On a square sail this is accomplished with leech and clew lines. See "Scandalize"
Breach - A breaking in of the sea. A clean breach is when a wave boards a vessel in solid form, and sometimes makes a clean sweep of the deck, taking crew, boats, and everything else overboard. To make a clean breach over a vessel is when the sea enters one side and pours out the other.
Break Aboard - When the crest of a wave falls aboard on the deck of a vessel.
Breakers - Casks for containing water. Also the disturbed water over reefs, rocks, shoals.
Breakers Ahead! -- The cry when breakers are sighted close ahead.
Break Off - In close-hauled sailing, when the wind comes more from ahead so as to cause the vessel's head to break to leeward of the course she had been sailing. Not to be confused with "fall off," which means that the vessel's head goes off farther away from the wind.
Break Tacks - When a vessel goes from one tack to the other.
Breaming - Cleaning off a ship's bottom by burning the excrescences thereon. Sometimes when a vessel is not coppered small worms will eat into the plank. It is usual then to scrape her bottom, coal tar her, and then bream her off by fire in basket breaming irons.
Breast Fast - A warp fastened to a vessel amidships to hold her.
Breasthook - A strong hook shaped wood knee used forward to bind the stem, shelf, and frame of a vessel together. Breasthooks are also used in other parts of a vessel. They are now usually made of wrought iron.
Breeze - In sailor's parlance, a strong blow of wind; but generally a wind of no particular strength, as light breeze, gentle breeze, moderate breeze, strong breeze. (See "Wind.")
Breeze of Wind.-- A strong wind.
Breeze-up - The wind is said to "breeze-up" when it increases fast in strength from a light wind.
Breezy Side - The windward side of an object.
Bridge - The location from which a vessel is steered and its speed controlled. "Control Station" is really a more appropriate term for small craft.
Bridge Deck - The transverse partition between the cockpit and the cabin.
Bridle - A short length of wire with a line attached at the midpoint. A bridle is used to distribute the load of the attached line. Often used as boom travelers and for spinnaker down hauls. or The parts of moorings to hold on by; many ropes gathered into one.
Brig - A two-masted vessel, square-rigged on both masts.
Brigantine - a two masted vessel square rigged on the foremast, with fore-and-aft sails on the mainmast

Broken Water - When waves lose their form by breaking over reefs, rocks, or shallows, or by meeting waves from another direction, termed a cross sea.
Broom at the Masthead - A signal that a boat or vessel is for sale. The origin of the custom appears to be unknown; but it is ingeniously argued that brooms were hoisted as a signal that a man wanted to make a clean sweep of his vessel; or the custom may have arisen from the common practice of selling brooms in the streets.
Brought To - After a vessel has been sailing off a wind when she is brought to wind, or close to wind.
Brought Up with a Round Turn - Figuratively, suddenly stopped: as for instance, when a rope is being payed out rapidly, if a turn or bight catches round some object and checks the paying out of the rope.

Buoyancy - The quality of floating or being supported or borne up by a fluid. A vessel is buoyant in proportion as she is bulk for bulk lighter than the fluid that supports her.
Burden or Burthen - Supposed to mean the quantity in tons of dead weight that a vessel will carry. The quantity would be the difference between the weight or displacement of the ship when light and the weight or displacement of the ship when she was laden as deeply as prudent.
Burdened Vessel - That vessel which, according to the applicable Navigation Rules, must give way to the privileged vessel. The term has been superseded by the term "give-way".

Caustic Soda.-- A mixture of three parts of caustic soda to two of unslacked lime is a good detergent. The soda is boiled in the water, and then the lime added. The mixture should be applied hot, and be of the consistency of thick whitewash. In applying it great care should be exercised so as not to allow it to touch the hands. A brush of vegetable fibre should be used, as the composition will destroy hair. Caustic soda is used for cleaning off old paint or varnish; the mixture should be put on nine or ten hours before it is scraped off if a very clean job is desired. If it is a deck that has to be cleaned it is desirable to damp it with fresh water before an application of the mixture; hence it is a good plan to apply it on a dewy morning. Mahogany should not be cleaned with this compound, which turns it black. A mixture of two parts soda and one part soap, simmered together and applied hot, is sometimes used. (See also "Sooji Mooji.")

In tacking or gybing the sail has to be lowered and the yard shifted to the other side of the mast. A plan has been proposed to perform this dipping by the aid of a topping and tripping line instead of by lowering the sail; but the balance lug, which requires no dipping whatsoever in tacking, is to be preferred to the best dipping arrangement.

Displacement Hull - A type of hull that plows through the water, displacing a weight of water equal to its own weight, even when more power is added.
Displacement per inch of immersion -
It is often necessary to now how much weight would have to be put into a yacht to sink her an inch or more deeper in the water or lighten her to a similar extent. Roughly, this can be ascertained by the following rule: Multiply the length on the load line by the breadth on the load line and divide the product by 600. (LxB/600)
The quotient will be the weight in tons or fractions of a ton. This rule would not hold good if the yacht were lightened more than three or four inches or deepened to that extent.
The rule is based on the assumption that the area of the load line is .7 of the circumscribing parallelogram. That is to say, the length and breadth multiplied together and again multiplied by .7 will (approximately) give the area of load line. Divide this product by 12, and the area is reduced to cubic feet, and divide again by 35 and the answer will be given in tons or fractions of a ton. By this rough rule the displacement per inch at any part of the hull of the vessel (if the measurements are taken at the part) can be found approximately
( LxBx0.7/ (12x35)) = ( LxB/600 )
