This video describes and shows you how to tie a loop in the end of a rope with a bowline knot. A bowline knot is used in rigging by the ground rigger to create a point for the up rigger to have a point to pull up. This is how you create a bowline knot. First you must create a loop in the middle of the knot. With the free end, come up through the loop, then you go around the standing end of the rope and then you move it back through the loop. You pull the knot tight. That is how you create a bowline knot.
