Jury mast head knot: used as a temporary measure in an emergency rigging of a jury mast, and is
placed at the mast head to form the band to which the stays and shrouds of the jury mast are secured.

The greater the strain set up in the rigging, the tighter the knot will grip the mast. It is made in the
centre of a rope with sufficient line to provide for the backstay(s).

Begin by laying down three bights (figure 83.1) which are then arranged one on top of another as in
figure 83.2. Then rearrange these so that the left-hand part of the right-hand side (or lower) bight lies
on top of the right-hand part of the left-hand side (or top) bight, with their overlapping in the centre on

the middle bight. Now pass your hands (figure 83.3) under and over the outer bights to pick up the
two overlapping bights in the centre. Pull these two bights out so that they weave over and under the
outer loops. Once out, you can pull up the loop lying at the top to give a clover-leaf effect (figure
83.4), with three loops to which the shrouds and forestay can be attached. The mast sits in the centre

of the knot, and the two ends of the rope are tied together with a bowline (see page 21), the long end
forming the back stay.
