Fig. 62 is the “sheepshanks” or “dogshanks”—a common and old-fashioned method of shortening, applicable to any size of cordage. The twist and chain knots are not suitable for very stout rope. Two bights are formed in the rope, as in Fig. 61; a half-hitch is then made at each end, and slipped over the bights. This is made more secure if a seizing is put round the two parts, A, B (Fig. 62). It can also be secured when ends of rope are free by passing each end through the adjoining bight, as shown in Fig. 63.

Fig. 65.—Sheepshanks Knotted.

Fig. 64 is a “knotted sheepshanks.” It differs from the last in that the ends are fastened rather differently. The two bights are made as before, and each end, after passing through the bight nearest to it, is put through the bight it has just made, thus forming an overhand knot at each end. In making Fig. 65, the parts of the rope are arranged as before. A marlinespike hitch (Fig. 40, p. 40) is made at each end and the bight put through it. The left side of Fig. 65 shows the knot made, and the bight in the act of being passed through it. It goes over the outside strand, under the centre one, and over the next. On the right side of the figure the loop is shown in its place, ready to be hauled taut.

Fig. 66.—Boat Knot Shortening or Sheepshanks Toggled.

Fig. 67.—Knot Shortening.

The “boat-knot” shortening (Fig. 66) is another form of sheepshanks. The ends are secured by bringing a portion of the loose part of the rope through the bight at each end, and toggling it with a belaying-pin or piece of wood, as in the boat knot (Fig. 44, p. 44). It is loosened readily, and can be made when both ends are fast.
