Comments
The Irish bowline is a fusion of two crossing knots; thus, the knot is symmetric although the loading isn't (see knot). One difference between the bowline and the Overhand & Fig.8 loopknots is the ease of untying; the bowline is easy to untie, whereas the other loopknots are not. Another difference is that the bowline can be completely formed after its eye had been sized: for example, after pulling the rope around a tree. For a Fig.8 or Overhand loopknot, one must first form part of the knot, leaving sufficient material to form the eye and complete the knot.
Structure
Symmetrically merged Crossing-knots
Tying
This knot can be tied in two ways: The first is a quick and easy way to tie the knot fast. The second way is for tying an object to a rope.
The quick way
First tie a cow hitch then cross the end over the standing part to form a pretzel. Second step viewing the knot from the side move the end under the knot to the back then through the middle of the cow hitch to the front. The Third step is to tuck the end into the loop to create, the Irish bowline. Dress the knot by pulling on all sides evenly.
As a hitch
This is better when attaching an anchor or object to a rope. First make a loop and then thread the rope through the object. passing the rope through the loop toward the back. Around the front passing the knot through the same loop in the opposite direction. This creates a second loop in the center of the knot. Thread the rope into the second loop pulling all sides evenly.
Untying
The knot can be untied in two steps: First, grab the end and the standing part and pull apart. Second grab the knot on both sides and pull apart. The knot will then fall apart.
