How to tie a Water Knot

Take the end of one rope and form an Overhand Knot (take the working end over the standing part as shown).

Take the end of a second rope (green) and, starting from the end of the first rope (red), follow the first rope into the Overhand Knot. We are about to 'double' the knot.

Continue to follow the path of the original end with the second working end. You must make sure that the second rope does knot cross over the first.

It should now look like this.

To tighten the knot pull on the ropes at either end. Make sure the knot is worked into shape and that one rope does not slip over the other.
