What is the maximum course change the guide ship should execute?

The correct maximum course change for a guide ship typically is set at 5 degrees. This guideline is designed to ensure precision in navigation and to maintain situational awareness during maneuvers, especially in tight or congested waterways. A course change of 5 degrees allows for adequate adjustment without causing significant disruption to the formation or navigation plan, keeping the movements of the ship smooth and predictable for other vessels.

In practice, making incremental changes helps in maintaining the stability of the guide ship, allowing other vessels in formation or convoy to respond accordingly without risking collision or confusion. As the need for efficient and safe navigation is paramount in maritime operations, this established limit promotes teamwork and communication among vessels transiting together.
