🔍 Key Concepts

• Rule 34 – Maneuvering and Warning Signals (sound signals for altering course or overtaking) • Difference between Inland and International overtaking sound signals • Special requirements for narrow channels vs open waters

💭 Think About

• Ask yourself: Under the International Rules, what sound pattern is specified for a vessel that intends to overtake another vessel? • Consider whether the question is about where the vessels are (location/condition) or what maneuver is being made. • Think: In which situation does the overtaking signal differ from the normal course‑alteration signals used when vessels are meeting or crossing?

✅ Before You Answer

• Verify in Rule 34 whether two prolonged followed by one short is associated with overtaking maneuvers or with restricted visibility signals. • Check if International Rules have special overtaking signals in narrow channels and what their exact blast patterns are. • Confirm whether restricted visibility signals are given at regular intervals and whether they match the pattern in the question.
