Clewlines (greenish) and buntlines (ruby) for a single sail. The canvas here is semi-transparent; fainter lines are running behind it.
Clewlines and buntlines are lines used to handle the sails of a square rigged transport.
The leechlines are clearly visible running inward and upward from the edges of the sail. The buntlines up the front of the sail can be seen too, simply their run to the blocks on the shrouds is obscured because the sail is assail a lifting yard.
Although the common perception of a traditionally rigged ship is that the sails are handled from "upwardly in the rigging", the majority of the work is actually carried out from the deck. In particular, when sailors go aloft to stow the foursquare sails by bundling them upwards and tying them to the chiliad (with gaskets) they don't have to pull the whole weight of the sail up towards them. That work has already been carried out from the deck using the clewlines and the buntlines.
As the name suggests, clewlines are fastened to the outer corners or clews of the canvass. They lift more weight than the buntlines, and also have to pull against the sheets - although these will accept been released at that place is still a certain amount of friction produced by the blocks and fairleads that they run through. For this reason the clewlines are ordinarily fitted with blocks to increase the mechanical reward. The clewlines are coloured green in the diagram, and run along the underside of the yard from the outboard ends to the mast, so downwards to the deck.
Buntlines lift the centre portion of the canvas; there will usually be four to 8 buntlines across the foot of the canvas. Traditionally they are secured to the canvas with buntline hitches.[1] Since buntlines only have to lift a section of canvas, they can be thinner than the clewlines and are not usually fitted with a purchase. A typical arrangement for the buntlines has them running through deadeyes on the k, upwards to a cake fixed to the shrouds a lilliputian higher upward the mast, and and so downwardly against the inside of the ratlines to the deck. This provides a expert lead merely does create a minor obstruction to sailors moving out along the yards.
Both clewlines and buntlines are unremarkably led to the deck against the inside of the ratlines. With half dozen or and so buntlines and two clewlines per sail, a transport with five sails per mast will take a lot of lines (notation, though, that clewlines and buntlines go to both sides of the deck, so at each set of shrouds there will only be four lines per canvass). It is usual to fit a wooden bar near the bottom of the ratlines, with a hole for each clewline or buntline, to keep them organised. The traditional layout is to have the lines from each canvas grouped together, starting from the forrad cease with the clewline and and so the buntlines. This will be followed by the clewline of the next canvas, and then on - the clewlines and hence the division between sails tin can be distinguished by their thickness. The everyman canvas's lines will be at the frontward cease of the rail, and the highest will be at the aft stop. There may non be an individual belaying pivot for each line; since the buntlines are invariably worked together several of them may be secured to the same pin.
Some sails, in addition to clewlines and buntlines, have leechlines to pull the edges into the eye when they are stowed (see picture). Notwithstanding, these can be treated exactly like buntlines, and it is generally not possible to identify a leechline from the deck.
Because the clewlines, and especially the buntlines, exercise non laissez passer through the axis on which the yard pivots, their effective length volition change as the yard is rotated round the mast from one tack to the other. When the sail is set, the lines can be left with enough of slack to let for this; if the sail is currently in its gear (see yardarm) and so information technology might be necessary to tend the lines as the yards are braced round.
