Question 470 Rules of the Road

The correct answer is D) A vessel overtaking another in a narrow channel. According to the International Regulations for Preventing Collisions at Sea (COLREGS), a vessel overtaking another vessel in a narrow channel must sound a signal of intent, which is typically two prolonged blasts, to indicate its intention to overtake. This helps ensure clear communication between the vessels and promotes safe navigation in confined waterways. The other answer choices are incorrect because they do not specifically relate to the requirement to sound a signal of intent when overtaking in a narrow channel. Vessels meeting head-on, the give-way vessel in a crossing situation, and vessels crossing the course of another have different rules and signaling requirements under the COLREGS.
