Heaving line

A heaving line is a length of rope that needs to be kept handy ready to throw to someone over the side.

The line should have sufficient breaking strain to haul a person back to the boat.

Whilst no length is technically specified, it is recommended that no less than 15 metres be used. Ideally, a handle should be attached to the end being thrown to the person in the water. Many on the market in years gone by have had a round rubber handle.
