Which of the following is not one of the basic towing methods?

The round-bow towing method, often referred to as a circle, is not considered one of the basic towing methods in standard practice. The emphasis in basic towing techniques is on effective and safe ways to connect and pull vessels, and the round-bow method does not align with established practices.

The single-line (bow-to-stern) method involves attaching a towline at the bow of the towing vessel and running it straight to the stern of the vessel being towed, providing a straightforward and effective way to control the tow. The double-line (bow-to-stern) method utilizes two towlines, which enhances stability and allows for more control, particularly when dealing with larger vessels.

The herringbone or V-pattern method is effective for maneuvering and provides a way for the towing vessel to make turns and control the towed object at angles. Understanding these foundational methods helps ensure safety and efficiency while towing, which is critical in powerboating scenarios.
