BOTH INTERNATIONAL & INLAND A tug is towing three manned barges in line in fog. The second vessel of the tow should sound which signal?

AI Explanation
The correct answer is C) No fog signal. According to the International Regulations for Preventing Collisions at Sea (COLREGS), when a vessel is towing another vessel, the towing vessel (the tug) is responsible for sounding the appropriate fog signal. The vessels being towed (the barges) are not required to sound a fog signal. The tug should sound one prolonged blast at intervals of not more than 2 minutes. The other options are incorrect because: A) One short blast is not the appropriate fog signal for a towing vessel; B) One prolonged and three short blasts is the fog signal for a vessel not under command, which is not the case here; and D) One prolonged and two short blasts is the fog signal for a vessel constrained by her draft, which is also not applicable to this scenario.
