Diagram for question 34
AI Explanation
The correct answer is C) two short blasts. According to the USCG Navigation Rules, when a power-driven vessel is overtaking another power-driven vessel in an inland waterway, the overtaking vessel (vessel "A") should sound two short blasts to indicate its intention to pass. This signals to the other vessel (vessel "B") that the overtaking maneuver is about to occur, allowing both vessels to coordinate their actions and ensure a safe passing. The other answer choices are incorrect because one short blast is not the appropriate signal for this situation, and sounding no signal or one prolonged blast would not properly communicate the overtaking vessel's intentions to the other vessel.
