Попадался текст 1843 года, T
he art of sail-making, as practised in the Royal Navy … 4-е издание.
Текст оцифрован с распознаванием, желающие могут потренироваться, см. стр. 19 – 20.
Отверстий для
rope bands естественно два на полотно, но в рифах – два через одно.
Любопытен четвертый абзац, если правильно понял, то люверсы в швах пробивали на полдюйма ниже,
чем те, что посредине полотен – первые способны нести большую нагрузку.
Для моделистов это без надобности, но в целом интересно
HOLES
Holes are made by an instrument called a pegging-awl, or a stabber, in large sails by a knife, and are fenced round by stitching the edge to a small grommet, made with log or other line; when finished, they should be well stretched or rounded up by a marling-spike or fid.
Sails have two holes in each cloth, at the heads and reefs of courses, top-sails, and other square sails ; in the royal navy the heads of first and second reefs of top-sails have alternately two holes in one cloth and one in another; one hole in every yard in the stay of flying jibs; and one in every three-quarters of a yard in the stays of square tack and other stay-sails.
REEF and HEAD HOLES of large sails have grommets of 12-thread line, worked round with 18 to 21 stitches: small sails have grommets of 9-thread line, with 16 to 18 stitches, or as many as shall cover the line, and smaller holes in proportion.
In order to strengthen sails, it has been recommended to have the holes in the heads and reefs placed thus: one hole to be made in the seam, another in the middle of the canvas, and so on alternately; the hole in the seam to be half an inch lower than the hole in the middle of the canvas.
By this the strain would lie upon the holes in the seam, which are more capable of bearing it than the holes in the middle of the single canvas.
It is likewise recommended to cut these holes with a hollow punch, instead of making them with a stabber or pricker. Cutting them with a knife, as used in the royal navy, answers the purpose.
The holes, for marling the clues of sails and the top-brims of top-sails, have grommets of log-line, and should have from 9 to 11 stitches twelve holes are worked in each cloth.
Marling-holes of courses are at three-fourths of the depth of the tablings at the clues from the rope and those of top-sails are at half the depth of the tablings at the clues, and top-brim, from the rope.
The tablings of all sails are of a proportionable breadth to the size of the sail, and sewed at the edge with 68 to 72 stitches in a yard.
