What does Rule 15 dictate concerning crossing situations?

Rule 15 of the International Regulations for Preventing Collisions at Sea (COLREGs) specifically addresses crossing situations. In these scenarios, it stipulates that the give-way vessel is required to take action to avoid collisions by keeping out of the way of the stand-on vessel. The give-way vessel should take early and substantial measures to steer clear of the other vessel when there is a risk of collision.

This rule is crucial for ensuring safe navigation, as it designates which vessel has the duty to maneuver and which vessel should maintain its course and speed. The rationale behind this is to minimize confusion and promote predictable behavior among vessels, fostering a safer marine environment. The concept of the give-way vessel acting to avoid a collision aligns with the overarching principles of maritime traffic management, emphasizing responsibility and clarity of action.

The other options are incorrect as they do not accurately reflect the obligations imposed by Rule 15. The stand-on vessel does have the right to maintain its course until it becomes clear that a collision cannot be avoided, and stopping is not typically an advisable action in crossing situations unless absolutely necessary for safety. Additionally, the right of way is not determined solely by the size of the vessels involved but rather by their relative courses and the circumstances of the encounter
