According to Rule 16, what action must the give-way vessel take?

Answer: A — Take action to avoid collision

Rule 16 of the COLREGs states that the give-way vessel must take action to avoid collision. This is a fundamental aspect of maritime navigation, emphasizing the responsibility of the vessel that is required to yield to ensure safety at sea. The give-way vessel must actively maneuver in a way that prevents any risk of collision with the stand-on vessel, which is the one that has the right of way. Understanding this rule is crucial because it directly impacts safety and navigational practices. Taking action may include altering course, reducing speed, or even stopping, depending on the situation. The intent of this rule is to promote proactive safety measures among vessels to avoid dangerous encounters. The other options are less suitable as they do not align with the responsibilities of the give-way vessel under Rule 16. While calling out to the stand-on vessel or maintaining position might be actions that could occur in certain scenarios, they do not fulfill the essential obligation of taking action to avoid collision. Additionally, increasing speed to escape could potentially escalate the risk of an accident, rather than mitigating it. Thus, option A encapsulates the correct and necessary action required by the rules.
