INLAND ONLY A power-driven vessel, when leaving a dock or berth, must sound what signal?

🔍 Key Concepts

• Inland Navigation Rules special sound signals vs. International Rules • Specific rule for power-driven vessel leaving a dock or berth • Difference between prolonged (long) blast and short blasts and when each is used

💭 Think About

• Think about why a vessel leaving a dock on inland waters would need to make a sound signal. Who needs to hear it, and what information does it give? • Recall which Inland Rule talks about maneuvering and warning signals. What does that rule say specifically about vessels leaving a dock or berth? • Compare the uses of prolonged/long blasts versus short blasts in other situations you know (meeting, crossing, overtaking). Which pattern best fits “I am leaving a dock”?

✅ Before You Answer

• Verify in the Inland Navigation Rules the exact wording for a power-driven vessel when leaving a dock or berth. • Confirm whether the term used in the rule is “prolonged blast” or “long blast”, and whether they are treated the same or differently in the Rules. • Double-check that the option you choose is not a signal reserved mainly for maneuvering in meeting/crossing/overtaking situations underway rather than departing a berth.
