Heaving line is a relatively light line than can be thrown from aboard a vessel to the shore, to another vessel or from the shore to a vessel.
The heaving line is connected to the actual line/hawser/rope that we wish to transfer between the endpoints but is too heavy to be thrown by itself.
Once the heaving line is transfered, it is used to transfer the heavy line between the two end points.
It is customary to weigh the throwable end of the heaving line to facilitate the throwing process, with a weight, e.g. a 'monkey fist' knot.
Canadian maritime law requires 15 meters minimum for a buoyant device heaving line. The U.S. Coast Guard does not specify a need for a heaving line. The UK Broads Authority does not specify a length for heaving lines. U.S. Coast Guard approved heaving lines come in lengths of 70 ft. and 100 ft. with an attached soft ball weight.
The purpose of a buoyant heaving line is to have a readily accessible line that can be thrown to someone in the water to help them stay afloat or to establish communication and aid in rescue efforts. The buoyant properties of the line ensure that it stays afloat and can be easily grabbed by the person in distress.

A buoyant heaving line is used to establish a temporary connection between vessels or between a vessel and shore. It aids in transferring lines or messages between them, particularly in situations where direct contact is not possible or safe, such as during rescue operations or when mooring. Its buoyancy allows it to float on water, making it easier to handle and retrieve when thrown.

Dry heaving is the reflexive action of vomiting without expelling any stomach contents. It can be caused by various triggers such as irritation of the throat or stomach lining, intense emotions, or illness, and often results in heaving or retching movements without any vomiting occurring.

The five ropes on a ship are the halyard, sheet, mooring line, towline, and heaving line. These ropes are essential for various tasks such as raising and lowering sails, securing the ship to a dock, towing other vessels, and throwing a line to another ship for communication or assistance.
