What is the term for the long, unused, or belayed end of a line?

The term "standing part" refers to the long, unused, or belayed end of a line. This segment of the rope is typically secured or held in place, while the other end of the line, known as the working part, is actively engaged in the task at hand, such as pulling or securing. Understanding the distinction between the standing part and the working part is crucial for safe and effective line handling aboard boats. The standing part is essential when tying knots or making adjustments since it provides the necessary slack or stability to properly execute these actions without risking the integrity of the line or the safety of the crew.
