The Heaving Line Knot, also known as the Monk's Knot, gets its name from the heaving line — a smaller line made to heave from a boat to dock so that it can be used to pull a heavier line over.

1 Double the line back for the length desired, and then begin tightly wrapping the running end around the doubled-up rope, making concentric circles to the left.

2 As you get to the end, tuck the running end through the last of the remaining bight. Pulling on the standing part will tighten this last tuck in place.

The Heaving Line Knot is useful for shortening a line and for weighting the end for heaving, if necessary. It is also used decoratively.
