Question 718 Rules of the Road

The correct answer is A) 40 meters. According to the International and Inland Navigation Rules (COLREGS), vessels 40 meters (approximately 131 feet) or more in length are required to exhibit two anchor lights when at anchor. The anchor lights must be visible all-around the horizon and positioned such that they are not less than 4.5 meters (about 15 feet) apart horizontally. The other options are incorrect because they specify lengths greater than 40 meters, which would not meet the regulatory requirement for displaying two anchor lights.
