BOTH INTERNATIONAL & INLAND Which vessel is to sound a fog signal of one prolonged followed by two short blasts?
AI Explanation
The correct answer is D) All of the above.
According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, the fog signal of one prolonged blast followed by two short blasts must be sounded by:
1) A sailing vessel underway
2) A vessel restricted in her ability to maneuver when carrying out her work at anchor
3) A vessel not under command
This signal indicates that the vessel is not under full command and may not be able to keep out of the way of other vessels. The other options are incorrect because they do not require this specific fog signal.
