The figure 8 knot is a simple and reliable stopper knot commonly used in sailing. Its main purpose is to prevent the end of a rope from slipping through a block, fairlead, or other fitting.
It is often tied at the ends of sheets and control lines. Compared with a basic overhand knot, it is usually easier to untie after being under load and is easy to recognize by its characteristic figure 8 shape.
How to tie a figure 8 knot?
Cross the working end over the standing part to form a loop. Pass the working end around the back of the rope, then bring it forward and through the loop. Pull the knot tight and leave enough rope beyond the knot so it cannot slip loose.
The figure 8 knot is quick, practical, and one of the essential knots every sailor should know.
