Question 596 Rules of the Road

The correct answer is B) 2 white towing masthead lights. According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a vessel of 20 meters or more in length engaged in towing another vessel astern must display two white towing masthead lights. This is because the length of the tow (75 meters) exceeds 200 meters, which requires the display of two towing masthead lights. The other answer choices are incorrect because: A) 1 light would not be sufficient for a tow of this length. C) and D) would require more than two towing masthead lights for a vessel of this size.
