Question 1009Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND Which vessel sounds the same fog signal when underway or at anchor?
AI Explanation
The correct answer is D) A vessel restricted in her ability to maneuver.
According to maritime regulations, a vessel restricted in her ability to maneuver, such as a vessel engaged in dredging or underwater operations, must sound the same fog signal as a vessel underway or at anchor - one prolonged blast followed by two short blasts, repeated at regular intervals. This is specified in the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules.
The other answer choices do not correspond to the specific fog signal requirement for a vessel restricted in her ability to maneuver, which is the key distinction in this question.
