Question 547Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND While underway in fog, you hear a prolonged blast from another vessel. Which vessel would sound this signal?
AI Explanation
The correct answer is C) A power-driven vessel making way.
According to the Inland and International Navigation Rules, a power-driven vessel making way through the water is required to sound a prolonged blast (4-6 seconds) at intervals of not more than 2 minutes when operating in restricted visibility conditions, such as fog. This signal is used to indicate the vessel's presence and position to other vessels in the area.
The other options are incorrect because a vessel being towed (A) would not sound this signal, and a sailboat making way (B) has a different sound signal requirement. Option D is also incorrect, as the prolonged blast is specifically for power-driven vessels making way, not necessarily those that are towing.
