Q

BOTH INTERNATIONAL & INLAND While underway in fog you hear another vessel sounding two prolonged blasts every two minutes. What does this signal indicate?

🔍 Key Concepts

• Sound signals in restricted visibility under Rule 35 of the Navigation Rules • Difference between a vessel "underway but not making way" and "making way through the water" • Special fog signals for vessels at anchor or aground vs. vessels underway

💭 Think About

• First, decide whether a vessel that is drifting is considered underway or not under the Rules. How does that change the fog signal? • Think about what sound signals are used by a vessel at anchor in fog. Does it normally use prolonged blasts on a whistle, or a different type of sound? • Recall which vessel must sound one prolonged blast versus two prolonged blasts in fog, and what extra conditions make that change from one to two.

✅ Before You Answer

• Verify under Rule 3 definitions whether "drifting" counts as underway • Check in Rule 35 exactly which vessels use two prolonged blasts and at what interval • Confirm what sound signals are prescribed for a vessel at anchor and whether they involve prolonged blasts on the whistle or bell/ gong signals
