Question 645Rules of the Road90% to pass

BOTH INTERNATIONAL & INLAND If a rowboat underway does NOT show the lights specified for a sailing vessel underway, it shall show which of the following?

AI Explanation
The correct answer is C) a white light exhibited in sufficient time to prevent collision. According to the International Regulations for Preventing Collisions at Sea (COLREGS) and the Inland Navigation Rules, a rowboat underway that is not exhibiting the required lights for a sailing vessel must show a white light in sufficient time to prevent collision. This is specified in Rule 25(d) of the COLREGS and Rule 23(e) of the Inland Navigation Rules. The other options are incorrect because A) and B) describe the required lights for a sailing vessel, not a rowboat, and D) specifies an all-round yellow light, which is not the correct light for a rowboat underway.
