Rules of the Road Question 309 diagram
A Hold course and speed
B Alter course to the left or right to give vessel "B" more sea room
C Alter course to the left
D Slow your vessel until vessel "B" has passed
AI Explanation

The correct answer is A) Hold course and speed. According to the Inland Navigation Rules, when a vessel desires to overtake another vessel on the starboard side, the overtaking vessel (vessel "B") is required to indicate their intention by sounding one blast. The vessel being overtaken (vessel "A") should then hold its course and speed, allowing the overtaking vessel to safely pass. This is the appropriate action specified in the rules, as altering course or slowing down could create an unsafe situation. The other options are incorrect, as they would go against the established navigation rules for an overtaking maneuver.
