How To Tie A Bowline On A Bight Knot

The bowline on a bite is simple once you understand how to tie it, but it can be hard to explain and visualize when you first learn about it. You may need to take some practice to get the hang of it.

Step One: Double up a section of rope by bending it in the middle, and form a loop with it.

Step Two: Pass the working end of the rope through the loop. This should form a double loop.

Step Three: Open the working end of the rope into a large eye, and bring it over the double loop, enveloping it.

Step Four: Pass the open working end over to the top of the eye.

Step Five: Tighten the knot by pulling the double loop downwards whilst keeping a firm grip on the standing end.

Things To Consider

Before using this knot in the field, take some time to familiarize yourself with its uses, quirks, and alternatives. Here are a few things to keep in mind.

Warnings

Tests have shown that the Bowline On A Bight Knot can slip if it’s unevenly loaded. For the best results, if you’re putting stress on it, be sure to put equal stress on both loops. If you’re a climber, keep this in mind when fastening your carabiner through these knots.

Alternatives

Even though the Bowline On A Bight Knot rarely slips and won’t bind, it’s always best to consider using a strong backup knot with it if possible. Failing that, try using an alternative knot instead. Good alternatives include the Alpine Butterfly Loop and the Figure-Eight Loop. The Figure-Eight Loop is a variation of the classic Figure 8 Knot, which you can learn about here.
