A useful midline knot that originates from mountain climbing, but is very useful on a yacht. It’s among the most secure of knots and it can be done in just three steps.
Advantages
- Does not slip easily once set properly
- Easy to untie
- Fast to tie once its familiar.
- Suitable for three-way loading
- Uses less rope than other similar knots like the figure 8
- Allows easy adjustments of the loop sizes
- Comparatively more stable than other midline knots like the figure 8 loop and bowline on a bight
Disadvantages
- Needs some practice to perfect the knot
- Difficult to tie with one hand
- Improper tying can result in a ‘false butterfly knot’, which looks similar, but is inferior in quality
Uses
- Typically used for creating loops to add eyes and shackles in any line
- Isolating a worn out part in the rope
- It’s really good to cinch down loose items on the deck
