The Bowline with Stopper is a reinforced version of the standard Bowline knot, where the working end is secured with an Overhand Knot around the loop. This modification enhances security, making it popular in climbing, rescue, and other high-stakes activities where knot failure is not an option.

Advantages

Provides extra security by preventing the Bowline from loosening or capsizing under load, making it ideal for critical applications like climbing and rescue.

Disadvantages

Slightly more complex to tie than a standard Bowline and may require more rope length due to the added stopper knot.
