The idea of “lay” is used to describe three different characteristics of wire rope. Rope should never be stowed away until thoroughly dry.When first introduced, it was thought that great difficulty would be found in manipulating wire rigging, but our best riggers cut, fit and splice it as readily as they do hemp rigging.

Traditionally made twisted rope. Definition from Wiktionary, the free dictionary. Whereas in ordinary rope, known as hawser rope, the three strands are laid up from left to right, in cable-laid rope the three hawsers must be laid up from right to left; otherwise the strands in the hawser become untwisted and lose much of their strength and durability.

Laid rope, also called twisted rope, is historically the prevalent form of rope, at least in modern Experiments show that four-stranded rope, when under 5 inches, is weaker than three-stranded of the same size; but from 5 to 8 inches, the difference in strength of the two kinds is trifling, while all above 8 inches is considered to be equal to plain-laid when the rope is well made.One set of wheel-ropes is now supplied of flexible iron wire-rope.A length of junk being brought on deck, you proceed to unlay it by attaching the strands to separate hooks, and the loper to the other end-one hand holding back on it, and then heaving back-two hands following the rope down to separate the ends.Of the worst junk, swabs and spun-yarn should be made; of the best, nettle and seizing-stuff, lacings, earings, &c.Rope contracts very considerably by wetting it. In port, during good weather, the rigging may be coiled down in flemish coils, that is, perfectly flat, as soon as the decks are dry enough in the morning, and left so until the decks are cleared up at seven bells in the afternoon, when the ends should be run out, the rope coiled down snugly and triced up in readiness for washing decks in the morning.Fig.
Regular lay denotes rope in which the wires are twisted in one direction, and the strands in the opposite direction to form the rope. For the same reason in rainy weather, braces, halliards, sheets, clew-lines, and other rigging requiring it, should be slacked up to save an unnecessary strain on the rope, and avoid the risk of springing a yard or carrying something away.THERE are four varieties of rope in the United States naval service: that made of the fibres of the hemp plant; the Manilla rope, made of the fibres of a species of the wild banana; hide rope, made of strips of green hide, and wire rope.It has been ascertained that a good selvagee, carefully made with the same number and description of yarns, as the common three-stranded plain-laid rope, possesses about the same degree of strength.By multiplying the square of the circumference of a wire rope by 4.5 for iron wire and 8.4 for steel wire and extracting the square root of the product, the circumference of a hemp rope of corresponding strength may be obtained.For a brief description of the process of rope-making, see Appendix A.Each strand has a hemp heart, and the rope itself has a heart usually of the same material; this adds greatly to its pliability.No cordage should be subjected to a strain above one-third of its estimated strength.As many lengths of spun-yarn can, of course, be made at once as there are hooks on the winch.The tarred plain-laid ranks next in point of strength, and is in more general use than any other.
stronger than iron wire of the same size.The divisor for hempen cables is 4.79.Avoid covering hemp rope with leather, especially green hide, unless good and well-tarred parcelling be interposed.When scrubbing clothes or hammocks, soap at times unavoidably gets on the rigging: it should be carefully washed off before the decks are dry.Italian hemp is only used in the navy for packing for engines, its cost being more than double that of Russian hemp.For fine seizings and service, hambroline and roundline (right-handed), or marline and housline (left-handed) are the kinds of small stuff selected.
