INLAND ONLY In a narrow channel, you are underway on power driven vessel "A" and desire to overtake power driven vessel "B". After you sound two short blasts on your whistle, vessel "B" sounds five short and rapid blasts on the whistle. What action should you take?

Correct Answer: Option B — hold your relative position, and then sound another signal after the situation has stabilized

Inland Rules Annex V and Rule 34 outline that five short and rapid blasts serve as the danger signal indicating disagreement or safety doubt. Mariners must hold relative position and sound another signal once the situation stabilizes.
