(11). Jury Knot. The jury knot is useful when a jury mast has to be rigged, as the loops form a means of attaching the necessary supports to the mast. The centre k (Fig. 120) is slipped over the masthead, and the weight brought on the stays tightens it and holds it in its position on the mast.
It is formed by three ordinary half-hitches, each placed behind the other and with the loop of the last laid over the first, as in Fig. 119.
Having done this, keep the hitches together with the right hand, and with the left take a and dip it under b and pull c through a and b. Then, holding the knot with the left hand, place f over e, and pull d between e and f. Take g in the teeth and pull on the parts g, f, and a. The ends h and z may be either knotted or spliced.
