From the captain
Before you start
A stopper knot has one modest job: stop the end disappearing through something. When it fails, that modest job suddenly becomes the whole afternoon.
By the end of this lesson
Tie a stopper and check it against the opening it is intended to stop at.

The figure-of-eight stopper
Loop, round behind, down through the loop, then dress it. Seen from your side, with the standing part leading away up the drawing.
5/5Dress it firmly and leave enough tail for the knot to remain visible and secure.Then check it is larger than the opening it must stop at.

The opening decides
A stopper must physically suit the opening as well as be correctly tied.
4/4The end runs away through the fitting. A simple reset becomes a re-reeving job.The knot has failed the size check. Confirm the suitable stopper arrangement.

What to look for
Inspect the finished form
Identify the dressed figure-of-eight, its tail and whether the finished knot is larger than the sample opening.
Choose the job as carefully as the knot
Equipment may specify a different stopper or no end knot. A generic stopper must not create a new machinery hazard.
The lesson
The lesson
- 01
Make a proper stop
Pass the working end around the standing part and back through the loop to form a figure-of-eight. Dress it firmly and leave enough tail for the knot to remain visible and secure.
- 02
The opening decides
The finished knot must be larger than the fairlead, block or fitting it is meant to stop at. A tiny figure-of-eight in soft line may pull through a large opening.
- 03
Check before the line runs
Fit the stopper before feeding or using the line where practical. If the vessel specifies another stopper or no knot because of an equipment hazard, follow that method.
Where it goes wrong
A control line is fed through a fairlead without a stopper. The end runs away, disappears through the fitting and turns a simple reset into a re-reeving job.
Your call
What would you do?
Pick one, then read the feedback on all three.
The situation
The dressed knot can pass through the sample fairlead without resistance.
Take it aboard
Tie and inspect: Figure-of-eight stopper
Do this during your induction or first weeks, with the person responsible for your work.
Unloaded practice
Use a short training line at a stable bench. Ask an experienced crew member to check the finished form before practising independently.
- 01Tie the figure-of-eight from the demonstrated view.
- 02Dress it and inspect the visible tail.
- 03Compare it with an inert sample opening without a running line.
- 04Explain an equipment-specific reason to check the instructions.
What a useful result looks like
- Identify the dressed figure-of-eight, its tail and whether the finished knot is larger than the sample opening.
- You can name one unsuitable use and untie the unloaded example without rushing.
Stop: Training line only. No person, vessel, lifting system or live load attached. A knot exercise does not establish load capacity or operating authority.

Figure-of-eight stopper: inspect and choose
From the lesson: Stopper knots: keep the end in sight
- Task and required holding or release behaviour understood.
- Line and attachment suitable under the vessel's method.
- Identify the dressed figure-of-eight, its tail and whether the finished knot is larger than the sample opening.
- Tail and finished form checked against the demonstrated method.
- Use limitations explained.

Your vessel's procedures and senior crew come first. Nothing on this card is stored.
Quick check
Four decisions, then move on
This check confirms the principle. Your vessel's own induction still comes first.
