Captain Gerry demonstrates how to tie a Figure 8 knot. The Figure 8 knot provides a quick and convenient stopper knot to prevent a line sliding out of sight. Its virtue is that, even after it has been jammed tightly against a block it doesn’t bind; it can be undone easily.

Step 1: Form a loop at the top, which we’ll call end A.

Step 2: Form another loop, creating an X where the rope crosses itself. The section of rope closest to end A should be passing under the other section, from top left to lower right of the X.

Step 3: Hold the X with your left hand.

Step 4: Use your right hand to poke end A into the hole.

Step 5: Pull on end A and tighten the knot.
