Question 775 Rules of the Road

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.
