AN
EXPLANATION
OF THE
TECHNICAL TERMS,
RELATING TO SHIPBUILDING.
With other Observations.


A

ABAFT, signifies the hinder part of the ship, or that part nearest the stern.

AFORE, is applied to any thing placed nearer the head than stern.

AFT, that part of the ship from the midships to the stern.

AFTER, is a term applied to any thing belonging to the aft part of the ship, as after body, after timbers, &c.

ANCHOR STOCK, a method of working planks, whereby the butt of one plank comes nearly over the middle of another plank, and the planks being broadest in the middle, and tapered to the butts, they thereby appear in shape like an anchor-stock.

APRON, is a part brought on to the aft side of the stem, in order to strengthen it, the scarphs therefore should always be disposed clear of those of the stem; when the rabbet of the stem is at the aft part, the apron is frequently sided more than the stem, that it may receive the fastenings of the fore hoods; but as the fastenings must all be drove nearly in one direction, they are liable to split the apron, therefore it is much stronger work when the rabbet of the stem is in the middle, because then the apron is sided the same as the stem, and the knightheads are fayed close to the stem and apron, and bolted through both; the butt end bolts may then be drove into the knight-heads, which are broad enough to admit of their being cross bored, and also secures the butts of the fore hoods much better than when they are fastened to the apron.

B

BACKSTAY-STOOL, are short pieces of plank, fitted for the dead eyes of the back stays, the same as the channels.

BALCONY, the gallery in the stern, which is chiefly in large ships.

BEAK-HEAD, is a small platform in large ships at the fore part of the upper deck, it serves occasionally for the use of a gun, for which reason it should be placed at the same height as the port sills; but it is chiefly for the conveniency of the men.

BEAMS, are the large pieces of timber placed across the ship under the decks, their ends are lodged on the clamps and fayed to the timbers, and being bound to the side by knees, they therefore support and keep the ship together.

BEARDING, is a term applied to the diminishing of any piece of timber or plank from a given line, such as the bearding line of the dead wood, bearding of the clamps, plank sheers, fife rails, &c.

BELLY, the inside or hollow part of compass timber, the outside of which is called the back.

BEND, the form of the ship's body from the keel to the top of the side, at any particular place, as at the broadest part of the ship it is termed the midship bend.

BEVELLING, is a term applyed to any alteration from a square: there are two sorts of bevellings, viz. Standing, and under; by a standing bevelling is meant that which is without a square, and an under bevelling, that which is within a square.

BINDING-STRAKES, are two strakes of oak in the decks, generally wrought near the comings, and worked all fore and aft, they are thicker than the rest of the deck, and let down between the beams and ledges, so that the upper side shall be even with the rest of the deck, the design of them is to strengthen and bind the deck so well together as to prevent its drawing.

BULGE, that part of the ship she bears on, when on the ground.

BULGEWAYS, those pieces of timber which are placed under the bulge of the ship to support her when launching: their extreme distance is generally one third the breadth of the ship, but this should wholly be governed by the form of the midship bend,

CHANNELS, are broad planks fitted to the ship's side, for the purpose of fitting the dead eyes; they are generally fayed close to the ship's side, by which they harbour a great deal of wet and dirt, and by that means help to rot the side, and likewise the channel; they should therefore have an opening between them and the side, about one inch and half or two inches, letting them be close to the side only at those places where the bolts go through, so that there would always be a passage for wet, dirt, &c. and would likewise admit of the air passing through, which is another very necessary matter.

CHANNEL-WALES, are those strakes worked between the gun deck and upper deck ports of large ships, for the strength of the topside, and are generally placed in the best manner possible, to admit of the deck bolts passing through them.

FLARING, signifies opposite to falling home, as when a ship's side forward falls out from a perpendicular, they say she has a flaring bow.

FLOORS, the lowermost timbers of the ship, upon which the whole frame is erected; they generally extended as far forward as the fore mast, and as far aft as the after square timber, in the after part of the ship; they are very difficult to procure, and in large ships are made in three pieces, which occasions a great consumption of timber to little purpose; for the floor being designed to go in its usual place, two of the pieces are made to butt at the middle line, then a large chock is placed across them and bolted to each, the upper side of which chock is kept well with the cutting down, so that from the upper part of the chock to the head of the floor timber, there is very little shift of timber to bolt the frame, because the lower futtock must be shortened to step on the chock; it would therefore be stronger to have a floor of natural growth, even if one arm was no longer than the distance from the chock to the floor as before mentioned, for then the lower futtock would extend to the dead wood, and might thereby be bolted through the short arm of the floor; but if a floor of natural growth with one short arm was not approved of, it would be best to secure the floor ribband as far as the aft part of the square body, and then put in the lower futtocks, which might be bolted through the dead wood, and placing the chock at the aft side of the lower futtocks it might be bolted to them; this would require the second futtocks to be somewhat longer at the heels, in order for them to step on the chock, which in this part of the ship might be very easily procured. This method would increase the shift of timber, be much stronger, and also favour the conversion of timber, for the halves of the floors must be cut from the butt of the tree to gain substance at the lower end, and therefore might at the same time be converted to a lower futtock; the regular bolting of the floors would also be preserved, as the chock would be in the place of the floor, and this would always be of sufficient strength in this part of the ship, when floors of a proper growth could not be obtained.

K

KEEL, those pieces of timber which are joined together endways, and are first laid down, upon which the whole structure is erected; the keel is generally of elm, except the after piece, which is sometimes oak, the number of pieces in the keel is not very material, so as they give a good shift to the pieces of keelson, and likewise the main mast, the scarphs of the keel are secured with a hook in the middle, which should fay very close, being designed on purpose to bear the strain of caulking the butts that the bolts in the scarphs may not be strained.

KEELSON, pieces of timber placed within side the ship exactly over the keel, for the purpose of binding and strengthening the lower part of the ship, it is bolted through the floors, and likewise the keel: the scarphs should be disposed between the scarphs of the keel, and if possible should likewise be disposed clear of the main mast and fore mast, and also the main hatch-way; as every other floor timber is bolted through the keel, and every other through the keelson and keel together, it requires that the middle of the scarphs of the keelson should be disposed over floor timbers that is designed to be bolted through the keelson.

KEVELS, are small pieces fixed within side on the spirketting of the quarter deck, to answer the purpose of timber heads where they are deficient.

KNEES, are those crooked pieces of timber which secure the beams to the ship's side: in those parts of the ship afore and abaft, where knees of wood cannot be procured of a good growth, knees of iron are generally placed, but iron knees must by no means be placed in other parts which require any great strength, for the bolts cannot be drove tight in the iron knees, therefore if the ship strains they consequently will work; the lodging knees are generally disposed on that side of the beam which makes them without a square, and the hanging knees must be placed so as to be clear of the ports, and likewise of the standards on the deck below; they should also be placed on that side of the beam, where riders may be occasionally introduced in their stead, the lodging knees are generally hooked into the beam, near the toe of the knee where the wood is short grained, it is therefore better to leave a tenon in the crown part of the knee at a proper distance from the end of the beam, which will bear the greatest strain, and be much the strongest method.

KNEE of the HEAD, that part which is bolted to the fore part of the stem, and supports the figure, rails, &c. It is composed of several pieces, by reason of its great breadth, and is secured on each side by large knees called the cheeks of the head.
