Two short blasts indicate overtaking on which side?

• A. Overtaking on starboard side
• B. Overtaking on port side
• C. Five or more short blasts
• D. Signals for attention

Answer: (B)

Two short blasts are used to signal an overtaking situation, and they indicate the overtaking vessel intends to pass on the other vessel’s port (left) side. This clear signal helps the other vessel understand which side the pass will occur on, so both can keep their courses and speeds as appropriate to avoid collision. The signal for overtaking on port is distinct from signals that would indicate passing on the starboard side or other maneuvers, ensuring there’s no confusion about the intended passing side.
