All the fore-and-aft stays are now set up on their ends, and should be leathered in their nips, as well as in their eyes.
The main topmast stay goes through a heart or thimble at the foremast-head, or through a hole in the cap, and sets up on deck or in the top; and the mizzen topmast stay sets up at the mainmast-head, above the rigging.
Jib, Topgallant, and Royal Rigging.—The jib stay sets up on its end on the larboard side of the head, and is served ten feet from the boom, and its collar is leathered like that of the topmast stay. The gaub lines or back ropes go from the martingale in-board. The guys are fitted in pairs, rove through straps or snatches on the spritsail yard, and set up to eye-bolts inside of or abaft the cat-heads. The foot-ropes are three quarters the length of the whole boom, and go over the boom-end with a cut splice. Overhand knots or Turks-heads should be taken in them at equal distances, to prevent the men from slipping, when laying out upon them.
The most usual method of fitting topgallant rigging in merchantmen, is to reeve it through holes in the horns of the cross-trees, then pass it between the topmast shrouds over the futtock staff, and set it up at an iron band round the topmast, just below the sheave-hole; or else down into the top, and set it up there. To get the length of the starboard forward shroud, measure from the topgallant mast-head to the heel of the topmast, and add one half the circumference of the topgallant mast-head. Its size should be about five sevenths of the topmast rigging. Each pair of shrouds should be served below the futtock staves. They are fitted like the topmast shrouds. The fore-and-aft stays of long topgallant masts go with eyes, and are served and leathered in the wake of the foot of the sails. The fore topgallant stay leads in on the starboard side of the bowsprit, and sets up to a bolt at the hawse-piece; the main leads through a chock on the after part of the fore topmast cross-trees, and sets up in the top; and the mizzen usually through a thimble on the main cap, and sets up on its end.
The topgallant backstays set up on their end, or with lanyards in the channels; and for their length, measure from the mast-head to the centre of the deck, abreast the bolt in the channels.
The royal shrouds, backstays, and fore-and-aft stays, are fitted like those of the topgallant masts, and bear the same proportion to them that the topgallant bear to the topmast. The fore royal stay reeves through the outer sheave-hole of the flying jib-boom, and comes in on the larboard side; the main through a thimble at the fore jack-cross-trees; and the mizzen through a thimble at the maintopmast cap. The flying jib-stay goes in on the starboard side, and sets up like the jib-stay. The gear of the flying jib-boom is fitted like that of the jib-boom.
Ratling.—Swift the rigging well in, and lash handspikes or boat's oars outside at convenient distances, parallel with the shear-pole. Splice a small eye in the end of the ratlin, and seize it with yarns to the after shroud on the starboard side and to the forward on the larboard, so that the hitches may go with the sun. Take a clove hitch round each shroud, hauling well taut, and seize the eye of the other end to the shroud. The ratlins of the lower rigging should be thirteen, and of the topmast rigging eleven inches apart, and all square with the shear-pole.
Standing Rigging of the Yards.—The first thing to go upon the lower yard-arm, next the shoulder, is the head-earing strap; the next, the foot-ropes; next, the brace-block; and lastly, the lift. The foot-ropes go with an eye over the yard-arm, are rove through thimbles in the end of the stirrups, (sometimes with Turks-heads, to prevent their slipping,) and are lashed to bolts or thimbles, but now usually to the iron trusses. The stirrups fit to staples in the yard, with an eye-splice. The lifts should be single, and fitted with an eye over the yard-arm, and lead through a single block at the mast-head, and set up by a gun or luff tackle purchase, with the double block hooked to a thimble or turned in at the end, and the lower block to an eye-bolt in the deck. Instead of brace-blocks on the fore and main yards, brace-pennants fitted over the yard-arm with an eye are neater. The latest and neatest style of rigging lower yards is to have a strong iron band with eyes and thimbles round each yard-arm, close to the shoulder; and then fit the lift, foot-rope, and brace-pennant, each to one of these eyes, with an eye-splice round the thimble or with a hook. The lower lifts now, for the most part, cross each other over a saddle upon the cap, instead of going through blocks.
The inner ends of the foot-ropes to the topsail, topgallant and royal yards, cross each other at the slings; and on the topsail yard there are Flemish-horses, spliced round thimbles on the boom-iron, and the other end seized to the yard, crossing the foot-rope. A neater mode is to hook the outer end of the Flemish-horse, so that it may be unhooked and furled in with the sails when in port. Next to the foot-ropes go on the brace-blocks, and lastly, the lifts. The rigging to the topgallant and royal yards is fitted similarly to that upon the topsail, except that there is nothing over the yard-arms but foot-rope, brace and lift. The brace to the royal yard fits with an eye. The reef-tackle, studding-sail halyard, and other temporary blocks, are seized to the lower and topsail yard-arms by open straps, so that they may be removed without taking off the lift. The topgallant studding-sail halyard block is often hooked to the boom-iron, under the yard.
The foot-ropes to the spanker-boom should be half the length of the boom, going over the end with a splice, covered with canvass, and coming in one third of the way to the jaws, and seized to the boom by a rose-seizing through an eye-splice. The next to go over the boom-end are the guys, which are fitted with a cut-splice covered with canvass, and have a single block turned in at their other ends. To these single blocks are luff or gun-tackle purchases, going to the main brace-bumpkin. Their length should be two fifths that of the boom. The topping-lifts are usually hooked into a band or spliced into bolts about one quarter the distance from the outer end of the boom, and reeve through single blocks under the top, with a double or single block at their lower ends.
All the splices and seizings of the standing rigging should be covered with canvass, if possible, except in the channels and about the head, where they are too much exposed to the washing of water. A vessel looks much neater for having the ends of the rigging, where eyes are spliced, or where they are set up on their ends aloft or on deck, covered with canvass, and painted white or black, according to the place where they are. The lanyards and dead-eyes of the smaller rigging which sets up in the top may also be covered with canvass. The lanyards, dead-eyes, and turnings-in of the rigging in the channels, should always be protected by scotchmen when at sea, and the forward shroud should be matted or battened all the way up to the futtock staves.
In some smaller merchantmen the lower rigging is not infrequently set up upon its end to bolts in the rail. This is very inconvenient on many accounts, especially as all the seizings have to be come up with, and the nip of the shroud altered, whenever it is at all necessary to set them taut. This soon defaces and wears out the ends; while, with dead-eyes, only the lanyards have to be come up with. Some vessels set up their lower rigging with dead-eyes upon the rail. This is convenient in setting them up in bad weather, but does not give so much spread as when set up in the channels, and presents a more complicated surface to the eye. If the rigging is fitted in this way, you must deduct the height of the rail above the deck from the measure before given for cutting it.
Breast-backstays.—It is not usual, now, for merchant vessels to carry topmast breast-backstays. If they are carried, they are spread by out-riggers from the top. Topgallant and royal breast-backstays are used, and are of great assistance in sailing on the wind. There are various ways of rigging them out, of which the following is suggested as a neat and convenient one. Have a spar fitted for an out-rigger, about the size of one of the horns of the cross-trees, with three holes bored in it, two near to one end, and the third a little the other side of the middle. Place it upon the after horn of the cross-tree, with the last-mentioned hole over the hole in the end of the horn of the cross-tree, and let the after topgallant shroud reeve through it. Reeve the topgallant and royal breast-backstays through the outer holes, and set them up by a gun-tackle purchase, in the channels.[1] The inner end of the out-rigger should fit to a cleat, and be lashed to the cross-tree by a lanyard.
