Chair Knot
Also known as:Bosun's Chair
Description
The chair knot is a complex knot that forms a secure seat with a loop for sitting and a loop for back support. The structure consists of multiple interlocking loops that distribute the person's weight evenly. It is tied using a single rope without any hardware.
Common Uses
Used historically in maritime and industrial settings for hoisting a person for maintenance work, and in rescue operations where a harness is unavailable.
When to Choose This Knot
Choose this knot when a standard loop, bend, hitch, or stopper does not fit the task. Specialty knots often solve narrow problems and should be practiced slowly before field use.
Safety Notes
- Confirm the knot purpose before using it in a loaded system.
- Treat decorative, improvised, or unusual knots as non-critical unless tested and approved for the use case.
- Inspect the final shape carefully because specialty knots can be easy to misread.
How to Tie
- 1Form a large bight and tie an overhand knot to create a sitting loop.
- 2Create a second loop above the first for back support by manipulating the rope through the knot body.
- 3Adjust both loops to fit the user's body.
- 4Pass the standing ends through the back loop to form a bridle.
- 5Tighten all components evenly.
- 6Test the seat before loading with full weight.
Common Mistakes
- Using a specialty knot outside the job it was designed for.
- Confusing a decorative structure with a load-bearing structure.
- Skipping practice because the knot appears visually simple.
