Question 581 Rules of the Road

The correct answer is A) A 75-meter vessel restricted in her ability to maneuver. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel restricted in her ability to maneuver, regardless of length, must exhibit forward and after white masthead lights when underway and making way. This requirement applies to both international and inland waters. The other options are incorrect because: B) A 45-meter vessel engaged in towing is required to exhibit the lights and shapes prescribed for a vessel engaged in towing, not necessarily the masthead lights; C) A 100-meter sailing vessel is not required to exhibit masthead lights when underway; and D) A 150-meter vessel engaged in fishing is required to exhibit the lights and shapes prescribed for a vessel engaged in fishing, not necessarily the masthead lights.
