If two vessels are on a crossing course and there is a risk of collision, who should alter course?

Explanation:
When two vessels cross paths and there’s a risk of collision, the vessel that has the other on its starboard side must take action to avoid collision. This is the give-way vessel, and its responsibility is to alter course (and/or reduce speed) to ensure safe passage. The stand-on vessel, whose partner is on its own port side, should maintain its course and speed unless it becomes clear that collision can’t be avoided by the give-way vessel’s maneuver. So, the best action is for the give-way vessel to alter course to prevent the collision.
