🔍 Key Concepts

• Sound signals in or near areas of restricted visibility (fog signals) under Rule 35 of the Navigation Rules • Difference between a vessel underway making way, underway but not making way, and stopped/at anchor • Which signals are for power-driven vessels, which are for vessels at anchor, and which are for special vessels (e.g., towing, NUC, fishing)

💭 Think About

• First decide: in fog, is your vessel still considered underway when you stop your engines and are dead in the water? How do the Rules define "underway"? • Look at the options and match each pattern of blasts to the type of vessel or status (e.g., power-driven making way vs. not making way vs. at anchor). Which pattern goes with which? • Ask yourself: does the question say anything about being anchored or not under command, or does it only mention engines stopped and being dead in the water?

✅ Before You Answer

• Verify the definition of "underway" in the Rules of the Road (Navigation Rules definitions, Rule 3). • Check Rule 35 for the exact fog signal required for a power-driven vessel underway but not making way. • Make sure you are not accidentally choosing the signal for a vessel at anchor or a special vessel (towing, NUC, fishing, etc.) since the question does not say any of those apply.
