This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1922 edition. Excerpt: ...same parabolic curve should be in the jib as in the mainsail. This, in the vertical seamed jib, as in the mainsail, was obtained by cutting the cloth with a full roach on the luff, by broadseaming and by being roped full along the luff rope. You can sew a sail to a rope in such a way that the sail is tightly stretched along the rope, or full it by gathering the sail cloth up so it is slack, though of course it doesn t show wrinkles along the rope. Where a jib is cut with cloths running up and down parallel to the after leech, the diagonal cut across the goods along the stay or luff, being on the bias, is very easily stretched, and here is where in roping a jib, the cloth must be sewed slack or "fulled. The greatest strain on such a jib comes across the weakest edge of the cloth, the hoist, and yet if this be reversed and the gores put along the leech and foot, they go out of shape and a hard spot from clew to luff cuts the sail into two bags. The leech and foot are the edges that must be a perfect flattened curve, as the proper escape for the wind is all important, and to obtain this flattened curve, various compromises have been tried, as shown in Figs. 36, 37, 38 and 39. Wire luff ropes have almost entirely superseded the hemp ones in modern yacht sails, as that has far less stretch, and the continual strain on a luff rope of a jib is quite severe. The proper making of a jib is important, but to set it properly is of equal importance and a point not understood as is should be. The object of a jib is not to be a bag to catch wind, but a fair curve along the luff with a perfectly flat smooth leech, so after the wind has pushed the sail all it could, the wind has a free chance to escape. Any part of the...
