What is one use of the Figure 8 Bend knot?

The Figure 8 Bend knot is particularly effective for connecting two ropes, especially when the ropes are of different diameters or materials. This knot forms a strong and reliable link that is easy to untie after being under load, making it ideal for situations where two ropes need to be joined to create a longer line.

While using it for connecting ropes is a common application, the other options focus on tasks that typically require different types of knots. For instance, attaching a boat to a mooring post or securing a line to a cleat generally calls for knots that are more suited for securing rather than joining, like the cleat hitch or bowline. Creating a temporary fastening could be done with various knots that are specifically designed for that purpose, such as the clove hitch. Thus, the effectiveness of the Figure 8 Bend lies in its ability to securely join ropes while maintaining ease of use, which aligns perfectly with the task of extending a line.
