What does the signal "Warning-- I don't understand your intentions" imply?

The signal "Warning-- I don't understand your intentions" indicates that the vessel receiving the signal is not clear about the navigational plan or actions of the other vessel. This situation often arises in maritime communication when vessels are in close proximity to each other, and one vessel is unsure of the maneuvers being employed by the other. By expressing this lack of understanding, the vessel is highlighting the need for clarification to prevent potential collisions or misunderstandings during navigation.

In scenarios where vessels are navigating in limited visibility or during complicated maneuvers, clearer communication is essential. The signal serves as a prompt for the other vessel to communicate their intentions more explicitly, ensuring that both parties are on the same page regarding their navigational actions.

The other options do not accurately convey the meaning of the signal. For example, indicating a turn to starboard or agreement with navigation does not reflect a lack of understanding, which is the core issue the signal communicates. Similarly, the intention to overtake does not encompass the uncertainty that the warning signifies. This makes the understanding of option A crucial for safe maritime navigation.
