Heaving Line Knot Details
Uses: The Heaving Line Knot (ABOK # 538, p 88) is one of several such knots described by Ashley. It creates a simple, moderately heavy, heaving knot.
Tying it: The animation shows the structure of the knot. However, in practice, it is preferable to leave a loop each end during wrapping. When complete, pulling the end loop shrinks the other loop tightly around the short tail end. Then pulling the standing end shrinks the end loop.
Length Required: The number of turns used is optional and affects the length of rope required. The ten wraps here used about 3 ft of 1/4" diameter rope (0.9 m of 6 mm diameter). To save guessing or waste, test an initial wrap around three strands.
Using a Heaving Line: How to Split a Coil to to Heave a Line is Described Here. A Heaving Line should not be joined directly to the main hawser: it can be impossible to detach it when the hawser is loaded. Ashley recommends the use of an intermediate short length of rope. This allows the Heaving Line to be detached from the intermediate rope and reused.
Disclaimer: Any activity that involves ropes is potentially hazardous. Lives may be at risk - possibly your own. Considerable attention and effort have been made to ensure that these descriptions are accurate. However, many critical factors cannot be controlled, including: the choice of materials; the age, size, and condition of ropes; and the accuracy with which these descriptions have been followed. No responsibility is accepted for incidents arising from the use of this material.
