Question 579Rules of the Road90% to pass
BOTH INTERNATIONAL & INLAND In reduced visibility, you hear two prolonged blasts of a whistle. This signal is sounded by which vessel?
AI Explanation
The correct answer is B) A power-driven vessel dead in the water.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), a power-driven vessel not under command and making way is required to sound two prolonged blasts on the whistle in reduced visibility. This signal indicates that the vessel is not under command and cannot maneuver as required by the rules.
The other options are incorrect because: A) A vessel not under command and making way would sound one prolonged blast, not two; C) A vessel fishing with nets while at anchor is not required to sound this signal; and D) A sailing vessel on the port tack does not have an obligation to sound this signal in reduced visibility.
