Q

INTERNATIONAL ONLY Your vessel is backing out of a slip in a harbor and you can see that other vessels are approaching. You should sound which of the following signals?

🔍 Key Concepts

• International Rules – Sound and Light Signals (Rule 34) • Specific signals for astern propulsion vs. leaving a berth/slip • Difference between a manoeuvring signal and a warning signal

💭 Think About

• Which signal, if any, is specifically described in the Rules for a vessel leaving a dock, berth, or slip in an area where other vessels may be affected? • Look at the signals made with short blasts – which one indicates "I am operating astern propulsion" and which one is for a different purpose? • Under the International Rules, when you are unsure of another vessel’s intentions, which signal are you supposed to use, and does that match this situation?

✅ Before You Answer

• Check Rule 34 in the International Navigation Rules and find the subsection that talks about a vessel leaving a dock or berth. • Verify how many short blasts are prescribed for indicating astern propulsion. • Confirm which signal of five short and rapid blasts is used for danger or doubt, and ask yourself whether that’s what the question is describing.
