Question 775Rules of the Road90% to pass

BOTH INTERNATIONAL & INLAND A 45-meter vessel is pulling a 210-meter tow. Which lights is she required to exhibit?

AI Explanation
The correct answer is D) three masthead lights forward and one aft. According to the International and Inland Navigation Rules, a vessel 45 meters or more in length towing another vessel 200 meters or more in length is required to exhibit three masthead lights forward and one aft. This configuration helps to clearly identify the vessel as a towing vessel, differentiating it from other vessels. The other options are incorrect because they do not meet the specific lighting requirements for a vessel of this size and tow length. For example, option A would be missing the required aft masthead light, while options B and C have the wrong number or placement of masthead lights.
