What does one short blast indicate?

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

Answer: (B)

Sound signals are used to communicate maneuver intentions between vessels. A single short blast means I am altering my course to starboard. This lets nearby vessels know I plan to pass to their right side, so you should adjust your own course accordingly to avoid a close-quarters collision. Two short blasts would indicate an alteration to port, and three short blasts signal that I am operating astern propulsion. The other options don’t match the standard one-short-blast meaning.
