In rough waters, what should you do with the towline when towing a vessel?

In rough waters, paying out the towline to create a dip, known as the catenary, is essential for maintaining control and avoiding damage. The catenary allows for a buffer that can absorb some of the shock and movement caused by waves. When the towline is kept taut, it can lead to jerking motions that can potentially damage both vessels involved or cause the tow to break loose. A proper catenary helps to reduce strain on both the towing and towed vessel while allowing for smoother movement through choppy conditions. This technique enhances safety and effectiveness during towing operations in rough conditions.
