A heaving line knot[1] is a family of knots which are used for adding weight to the end of a rope, to make the rope easier to throw. In nautical use, a heaving line knot is often tied to the end of a messenger line, which is then used for pulling a larger rope, such as a hawser. There are several distinct knots which all share the common name, heaving line knot.[1] The monkey fist is a well-known heaving line knot.
