INLAND ONLY Vessel "A" is power-driven and overtaking power-driven vessel "B" as shown in illustration D017RR below and will pass without changing course. What signal should vessel "A" sound?

Correct Answer: Option C — two short blasts

Inland Rule 34(c)(i) dictates that a power-driven vessel overtaking another and intending to pass on the starboard side of the vessel being overtaken shall sound two short blasts. This signal clearly communicates the intent to pass on the starboard side to the vessel being overtaken.
