BOTH INTERNATIONAL & INLAND In a dense fog you hear a whistle signal ahead of one prolonged blast followed by three short blasts. Which vessel is required to sound this signal?
AI Explanation
The correct answer is A) A manned vessel being towed.
According to the International and Inland Navigation Rules, a manned vessel being towed is required to sound the signal of one prolonged blast followed by three short blasts. This signal indicates that the vessel being towed is not under command and may not be able to maneuver as easily as a vessel that is not being towed.
The other options are incorrect because: B) A pilot vessel would not use this signal, C) Fishing vessels trawling have different signal requirements, and D) Vessels not under command would not be required to sound this particular signal.
