Becket bend
1The knot in plain words
In one sentence…
The sheet bend joins two ropes, even of different thickness: the thicker one forms a bight and the thinner one locks around it.
What does it do?
It joins the end of one rope to the end of another, to make a longer line or add a light line to a heavier one.
When do I use it?
To extend a line, bend a light heaving line to a bigger working line, or tie a rope end to a small eye.
Which rope does what?
The thicker or stiffer rope forms the bight; the thinner one wraps around it and tucks under itself.
When not?
When the lines go slack and snatch, or differ a lot in size, it can shake loose. Tie the double sheet bend.

3How to check it
Step-by-step tying is being checked on real rope before we publish it. Until then, use the illustration and the checks below.
Both tails come out on the same side of the knot.
The bight is in the thicker or stiffer rope.
The thinner rope's end is trapped under its own standing part.
Both tails are clearly long enough.
4Key points
- 1.
Sheet bend = the bend for joining two ropes.
- 2.
Thicker rope makes the bight; thinner rope wraps and tucks.
- 3.
Both tails on the same side.
- 4.
Very different sizes, or slack and snatching lines: double it.
5Frequent mistakes
Mistake: Making the bight in the thinner rope.
Correct: The thicker or stiffer rope forms the bight; the thinner one wraps around it.
Mistake: Tucking so the two tails end up on opposite sides.
Correct: Tuck under the standing part so both tails lie on the same side.
Mistake: Trusting a single sheet bend on lines that flog slack, or on very different ropes.
Correct: Tie a double sheet bend and check it often.

7Questions sailors ask
What is a sheet bend used for?
▸
To join two ropes, especially of different thickness or stiffness, or to tie a rope end to a small eye.
How do I join two ropes of different thickness?
▸
Use a sheet bend: make the bight in the thicker rope and wrap the thinner one around it. For a big difference, tie the double sheet bend.
What is the difference between a sheet bend and a double sheet bend?
▸
The double takes one extra turn around the bight before tucking. It holds better when the ropes differ a lot or go slack.
Why is it called a sheet bend?
▸
It was used to bend a sheet to the clew of a sail. A bend is the sailor's name for a knot that joins two ropes.
8Test yourself
In a sheet bend, which rope forms the bight?
Screen study teaches what the knot is for and how to check it. It doesn't prove you can tie it: practise with real rope, and never use these knots for climbing, rescue or anything that holds a person.
