🔍 Key Concepts
• Rule 19 – Conduct of Vessels in Restricted Visibility (Navigation Rules)
• What actions are required when you HEAR, but do not SEE, another vessel’s fog signal forward of the beam
• Difference between specific legal terms like bare steerageway, safe speed, and moderate speed
💭 Think About
• Ask yourself: in restricted visibility, when I hear a fog signal forward of the beam and I’m not sure about risk of collision, does the rule tell me to stop almost completely, or just slow to a particular type of speed?
• Consider which of the answer choices is a term that actually appears in Rule 19 when describing required speed reduction.
• Think about how the rule’s wording distinguishes between initial action when you first hear the fog signal and later action if you determine that a close-quarters situation or risk of collision exists.
✅ Before You Answer
• Verify the exact phrase used in Rule 19(d) regarding reduction of speed when a fog signal is heard forward of the beam.
• Check which of the listed terms (bare steerageway, safe speed, half speed, moderate speed) is a formal Rule 19 term versus common seamanship language.
• Confirm that the required action includes both a change in speed and, if necessary, stopping the engines in the appropriate situation, and match that language to the answer choice that best reflects the rule.
