Question 571Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND You are operating in restricted visibility and hear a signal of a rapidly ringing bell followed by the rapid sounding of a gong. Which vessel is required to sound this signal?
AI Explanation
The correct answer is C) 300-meter power-driven vessel at anchor.
The International Regulations for Preventing Collisions at Sea (COLREGS) require a power-driven vessel of 100 meters or more in length to sound the signal of a rapidly ringing bell followed by the rapid sounding of a gong when anchored in restricted visibility. This signal is used to indicate the presence of the large, anchored vessel to avoid collisions.
The other options are incorrect because: A) a vessel in distress would sound different distress signals, B) a 30-meter sail vessel at anchor would not be required to sound this particular signal, and D) a 150-meter power-driven vessel aground would not be sounding this anchored vessel signal.
