When is it permissible for a vessel to carry out a crossing maneuver?

The correct answer emphasizes the importance of safety in navigation. A vessel is permitted to carry out a crossing maneuver only when it can be done safely without causing a collision. This rule is rooted in the overall principle of maritime navigation, which prioritizes the safety of all vessels operating in a shared waterway. Recognizing the potential risks and ensuring that the maneuver does not interfere with the navigation of other vessels is crucial for preventing accidents.

When assessing a crossing situation, the vessel must consider factors such as the speed, distance, and heading of both its own vessel and any approaching vessels. The responsibility lies with the captain to ensure that any crossing maneuver is executed without jeopardizing the safety of their vessel or others, reflecting the key navigational rules that promote safe passage on the water.
