Usage
The Running Bowline functions similarly to a noose, tightening when pulled. It is created by forming a Bowline Knot around the standing part of the rope, allowing the loop to slip and constrict under tension. This knot is commonly used in sailing and tree work. The Running Bowline is reliable and non-jamming, meaning it is easy to untie even after being heavily loaded. Its ability to tighten under load while remaining secure makes it ideal for tasks like hoisting, lassoing, or retrieving objects from difficult positions.
Common Uses
- retrieve objects that have fallen overboard or out of reach.
- tighten a loop around a bundle of branches for removal.
- lasso a post, piling, or other object from a distance.
- hang a tree swing by tightening a loop around a branch.
- cinch a rope around a heavy object for hoisting or dragging.
- rig a tree limb for removal by choking branches for lowering.
- pull over tree trunks during felling operations.
- hang something heavy from a beam or pipe with a tightening loop.
- pull a stuck vehicle free by cinching a rope around a tow point.
History
The Running Bowline is mentioned by name in the book A Four Years Voyage by Captain George Roberts published in 1726 that describes the events of his voyage to the Islands of the Canaries, Cape De. Verde, and Barbadoes and specifically mentions the Running Bowling Knot.

Structure
The Running Bowline is simply a standard Bowline where the loop formed when tying the Bowline encloses the standing end of the line. This can be tied at least two ways but if the rope is long or the standing end is secured, the method shown in the animation is the practical one.
Strength/Reliability
The Running Bowline is strong and secure but does not reduce the strength of a line.
