Question 155 Rules of the Road

The correct answer is C) A vessel of less than 20 meters in length. According to the International Regulations for Preventing Collisions at Sea (COLREGS), vessels of less than 20 meters in length shall not impede the passage of a vessel that can only navigate inside a narrow channel. This is outlined in Rule 9(b) of the COLREGS, which states that "A vessel of less than 20 meters in length or a sailing vessel shall not impede the passage of a vessel that can safely navigate only within a narrow channel or fairway." The other options (A, B, and D) are incorrect because they do not accurately reflect the COLREGS requirement for vessels of less than 20 meters in length to give way to vessels that can only navigate within a narrow channel.
