The Racking Bend is used to join ropes of different diameters, often used in maritime work.
It works a lot like the Double Sheet Bend, but has exceptional grip and is less likely to slip, even under heavy strain.
The term “Racking” comes from the figure 8 pattern that binds the bight of the thicker rope together.
Let’s learn it in detail.

How to Tie a Racking Bend
- Make a bight with the thicker rope.
- Pass the thinner rope into the bight and start weaving the rope in a figure 8 shape around and through the loop. Make at least 4 turns around the bight.
- Pull the knot tight and finish it off with a Half Hitch around the thicker rope.
If you are working with slick rope, add additional turns around the bight for extra grip.

Pros & Cons
- Strong and secure.
- Join ropes of unequal diameter effectively.
- Slightly complex to tie.
- Bulky in structure.
Application and Uses
The Racking Bend was developed by sailors to join ropes of different diameters for mooring or towing.
Today, it’s used to join mooring lines, docking, and even towing setups.
It’s also used to throw a heavy line, such as a hawser, from one ship to another or to the shore.
