BOTH INTERNATIONAL & INLAND Which light(s) must a sailing vessel of over 20 meters in length while underway exhibit?
AI Explanation
The correct answer is A) stern light.
According to the International Regulations for Preventing Collisions at Sea (COLREGS), a sailing vessel over 20 meters in length while underway must exhibit a stern light. This is required by Rule 21(c) of the COLREGS, which states that a sailing vessel shall exhibit a stern light. The other options are incorrect as they do not fully meet the COLREGS requirements for a sailing vessel over 20 meters in length. For example, a white masthead light (option B) or a combined lantern (option D) would not be sufficient on its own.
