INTERNATIONAL ONLY When two vessels are in sight of one another and NOT in or near an area of restricted visibility, any of the following signals may be given EXCEPT which signal?
AI Explanation
The correct answer is B) Four short whistle blasts.
This is correct because under the International Regulations for Preventing Collisions at Sea (COLREGS), the signal of four short whistle blasts is not one of the signals that may be given when two vessels are in sight of one another and not in or near an area of restricted visibility. The correct signals in this situation are A) A light signal of at least five short and rapid flashes, C) Two short whistle blasts, and D) One prolonged, one short, one prolonged, and one short whistle blasts.
The four short whistle blast signal is used to indicate uncertainty in the other vessel's actions or intentions, which is not the appropriate signal in this scenario where the vessels are in sight of one another and not in restricted visibility.
