Knots to Know: Figure eight knot
Superior to other common stopper knots, the figure eight knot can prevent a line from sliding through a retaining device. You can also use it in lashing to keep a line from sliding through a pulley or prevent a halyard from slipping into the mainsail rigging.
Step-by-step instructions for tying a figure eight knot
- Start by crossing the working end, or tail of the line, over the top of the standing line, making a Q shape.
- Twist the loop once away from the tail of the Q.
- Put the end of the line, or tail of the Q, up through the upper loop from behind.
- Pull both ends of the line to tighten the knot.
If the final knot resembles a figure eight, you’ve done it right.
To untie, push the ends together to loosen and then undo the working end.
