🔍 Key Concepts

• Rule 6 – Safe Speed of the Navigation Rules (factors to consider) • Difference between characteristics of the vessel itself vs. how you are actually operating it • Environmental and visibility factors that affect safe speed, especially at night

💭 Think About

• Look at Rule 6 and list the factors it specifically mentions. Which of the options is NOT on that list? • Ask yourself: which of these is about the vessel’s current handling and situation, and which is just a design/engine characteristic that may not change with conditions? • For nighttime operation, think about what visual conditions the rule talks about when determining safe speed.

✅ Before You Answer

• Verify which items are explicitly listed in Rule 6 as factors for safe speed (e.g., draft, maneuverability, visibility/background lighting, traffic, etc.) • Check whether engine size or maximum horsepower is ever mentioned in Rule 6’s list of factors • Confirm that the odd option out is the one that is not directly stated as a Rule 6 consideration
