When Is It Inappropriate To Use A Figure-Eight Knot?

Overloading and Wear

When subjected to excessive wear and tear, a figure-eight knot can come undone, leading to accidents and injuries. It’s essential to be aware of the limitations of this knot and use alternative knots like the bowline or the sheet bend in high-load applications. For example, when securing a sailboat to a dock with a cleat, a bowline knot is more suitable. The bowline can withstand up to 30% more force than a figure-eight knot in such scenarios. If you must use a figure-eight, ensure that it is not subject to repeated loading and unloading.

Alternatives to the Figure-Eight Knot

The figure-eight knot is not the only knot available for securing lines. Other knots like the bowline, sheet bend, and rolling hitch are more suitable for various applications. For instance, when working with lines that need to be frequently loaded and unloaded, like in search and rescue operations, a rolling hitch is a more reliable option. The rolling hitch is less prone to coming undone and can withstand more stress than a figure-eight knot.

Best Practices for Using a Figure-Eight Knot

To ensure the figure-eight knot performs as expected, it’s crucial to tie it correctly and inspect it regularly. A poorly tied figure-eight knot can come undone under stress, leading to accidents. To tie a figure-eight knot correctly, start by creating a loop in the line and then pass the working end over the standing part of the line, passing it through the loop. Pull the working end gently to secure the knot. Regularly inspect the knot for signs of wear and tear, and re-tie it if necessary.
