90% to pass

BOTH INTERNATIONAL & INLAND You are in charge of a 120 meter power-driven vessel at anchor in fog, sounding the required anchor signals. You hear the fog signal of a vessel underway off your port bow. Which signal may you sound to give warning of your position?

A At least five short and rapid blasts
B Two short blasts
C One short, one prolonged, and one short blast
D Three short blasts
AI Explanation

The correct answer is C) One short, one prolonged, and one short blast. This signal is the appropriate warning signal for a vessel at anchor in fog, as specified in Rule 35(g) of the International Regulations for Preventing Collisions at Sea (COLREGS). The regulation states that a vessel at anchor must sound this signal to warn other vessels of its presence and position. The other options are incorrect because they do not match the required signal in the COLREGS. Option A is the signal for a vessel not under command, option B is the signal for a vessel backing up, and option D is the signal for a vessel not making way.
