BOTH INTERNATIONAL & INLAND You are at anchor in fog. The fog signal of a vessel underway has been steadily growing louder and the danger of collision appears to exist. In addition to your fog signal, what signal may be used to indicate the presence of your vessel?
AI Explanation
The correct answer is A) Three blasts on the whistle; one short, one prolonged, and one short.
This signal is prescribed by the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules to indicate that a vessel is at anchor. The purpose is to alert other vessels in the vicinity to the presence of the anchored vessel, in addition to the required fog signal, to help prevent a collision.
The other options are incorrect because B) is the wrong sequence of blasts, C) does not allow for any additional signal beyond the fog signal, and D) is the wrong sequence of blasts.
