Question 358 Rules of the Road

The correct answer is C) sound one short blast. When meeting another power-driven vessel head-on in inland waters, the Rules of the Road (Navigation Rules) require each vessel to sound one short blast to indicate that they intend to pass port-to-port. By sounding one short blast, you are communicating your intention to pass the other vessel on its port (left) side, which is the proper action in this situation. The other answer choices are incorrect - changing course to port (A) would be the wrong maneuver, and holding course and speed (B) or sounding three short blasts (D) would not properly communicate your intentions to the other vessel as required by the Navigation Rules.
