90% to pass

BOTH INTERNATIONAL & INLAND A vessel engaged in fishing while at anchor shall sound which fog signal?

A One prolonged and three short blasts at two minute intervals
B A sounding of the bell and gong at one minute intervals
C A rapid ringing of the bell for five seconds at one minute intervals
D One prolonged and two short blasts at two minute intervals
AI Explanation

The correct answer is D) One prolonged and two short blasts at two minute intervals. This is the correct answer because according to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel engaged in fishing while at anchor is required to sound this fog signal. The regulations specify that vessels at anchor and not making way must sound one prolonged blast followed by two short blasts at intervals of not more than two minutes. The other options are incorrect because they do not match the specific fog signal required for a fishing vessel at anchor under the COLREGS rules.
