Double diamond knot: working from the diamond knot on four strands
(see page 64), follow around with each strand by passing it under two

parts and up through the third; however, the last strand will have to be
taken under two double parts. All strands will again emerge at the top.

Double figure of eight: is used when a single figure of eight is not big
enough to stop the rope running through an eye. It is formed in the same
way as a figure of eight knot (see page 80), but with an extra turn taken
around the standing part, before tucking the end down through the
bight.

Double fisherman’s knot: this is a stronger version of the fisherman’s
knot (see page 83), and particularly useful when working with a slippery
material such as nylon.

Start as for the fisherman’s knot, but tie a thumb knot (see page 171) with

an extra turn in each end (figure 52.1), before pulling tight (figure 52.2) to
form the completed knot.

Double line loop see Bimini twist

Double sheet bend or double becket bend: is more secure than the
single sheet bend (see page 149), and preferable when one of the ropes is
slippery.

Start by forming the single sheet bend, but complete a full round turn
