What does three short blasts indicate?

• A. I Am Backing Down
• B. I Am Altering My Course to Starboard
• C. I Am Operating Astern Propulsion
• D. I Am Leaving You on My Port Side

Answer: (C)

Three short blasts are a standard signal that a power-driven vessel is reversing propulsion ( operating astern). This tells nearby vessels that you’re backing up and may change your path or stop abruptly, so others should take appropriate action to maintain safe separation. The signal is brief and precise, used to communicate a contrasting maneuver in busy or restricted situations where verbal communication isn’t practical.
