Buoyant Heaving Line - Purpose - Minimum length

Definition of a Buoyant heaving line

A Buoyant heaving line is a floating rope that has a soft buoyant mass on one end. 


This buoyant heaving line is used to be thrown toward a person in distress in the water. To improve the accuracy of the throw overboard to a person overboard, a balloon or other floating object should be fixed to the buoyant heavy line. In addition, boaters should practice throwing the buoyant heaving line in order to develop their ability to be effective if an emergency occurs.


  • A buoyant heaving line is approved for use as long as it floats and is in good condition.
  • It must be made of one full length of rope, not many shorter ropes tied together
  • The lenght of the buoyant heaving line should be long enough for the boat you will be using and it is used only as safety equipment so that it is easy to find and use in an emergency.
