What is a bowline knot commonly used for?

A bowline knot is primarily used for creating a fixed loop at the end of a rope that does not slip. This characteristic makes it particularly useful in various rigging and sailing applications, where a reliable, non-slipping loop is necessary. For instance, the bowline can be used to secure a line to a post, tie a boat to a dock, or create a loop for attaching to a harness or other equipment. Its ability to maintain tension without slipping while being easy to untie after being loaded adds to its popularity among those who work with ropes.

This knot differs from others used for securing ropes together or tying down loads, as those applications typically require different types of knots that serve distinct purposes, such as the square knot or various hitch knots. While the bowline can be beneficial in situations that involve towing or other methods involving pulling, its primary and most recognized function remains making a non-slip loop.
