🔍 Key Concepts

• Inland Navigation Rules – Rule 34 (Maneuvering and Warning Signals) • Special Inland-only signal when leaving a dock or berth • Difference between short blast and prolonged blast definitions

💭 Think About

• Ask yourself: which rule in the Inland Rules specifically talks about the signal for a vessel leaving a dock or berth? • Once you find that paragraph, identify exactly how many blasts and what length (short vs prolonged) are required. • Compare that requirement to each choice and eliminate any answers that don’t match both the number of blasts and the duration.

✅ Before You Answer

• Verify the rule number and paragraph in Inland Rule 34 that covers leaving a dock or berth. • Confirm the definition of a short blast vs a prolonged blast in the sound signal definitions before deciding. • Make sure the signal you pick is specified as required Inland, not just a commonly used or International practice.
