Q

INTERNATIONAL ONLY A power-driven vessel leaving a quay or wharf must sound what signal?

🔍 Key Concepts

• Rule 34 – Maneuvering and Warning Signals (International Rules) • Difference between a prolonged blast and short blast in the sound signals definitions • When a power-driven vessel is leaving a quay or wharf (dock/berth) and what signal is prescribed

💭 Think About

• Look up Rule 34 in the International Regulations: what specific wording is used for a vessel leaving a dock or berth? • Check the formal definitions section for sound signals: how is a prolonged blast defined versus a short blast? • Think about whether the rules ever say that no signal is required when a vessel gets underway from a berth in restricted visibility or congested areas.

✅ Before You Answer

• Verify the exact phrase used in the rule – does it say long or prolonged? • Confirm how many blasts are required when leaving a berth under the International Rules. • Make sure you are not confusing this with signals for astern propulsion or operating in a narrow channel.
