Having the ________________________ working with the heaving line increases the range.

The correct answer focuses on the role of the person throwing the line when working with a heaving line. A skilled individual can significantly enhance the range of the throw by using proper technique. This includes elements such as arm strength, angle of release, and the ability to time the throw effectively, especially in coordination with environmental conditions.

While other factors can affect the range to some degree—such as the weight attached or the wind direction—they are less impactful compared to the skill of the individual. The effectiveness of the throw largely relies on the thrower's strength, technique, and ability to judge the conditions, making the person throwing the most critical element in maximizing the range.
