c. Running Bowline. The running bowline (Figure 4-24) forms a strong running loop. It is a
convenient form of running an eye. The running bowline provides a sling of the choker type at the end
of a single line. Use it when tying a handline around an object at a point that you cannot safely reach,
such as the end of a limb.
