What is a throw line used for in rope work?

A throw line is specifically designed for throwing over objects, making it essential in various applications, particularly in rope and rigging work. It is often lightweight and can be thrown with precision to establish a connection or to facilitate the movement of a heavier line or load. When utilized effectively, a throw line can be thrown over branches in tree work, buildings in rescue situations, or obstacles in outdoor settings, allowing for subsequent operations like securing equipment or bringing down materials.

In other contexts, such as heavy lifting or lowering materials, specific equipment designed for those tasks would be more appropriate and efficient. Similarly, while creating knots is a fundamental skill in rope work, a throw line itself is not primarily used for that function; it focuses on the act of throwing rather than tying. Therefore, the function of a throw line as a tool in rope work revolves entirely around its ability to facilitate throwing over objects.
