🔍 Key Concepts

• Rule 6 – Safe Speed and how the term is used in the Rules • Traffic Separation Schemes (TSS) and where they are addressed in the Navigation Rules • Stand-on vessel actions under Rule 17 – Action by Stand-on Vessel

💭 Think About

• For each choice, ask yourself: is this wording exactly how the Navigation Rules describe the concept, or is it slightly off? • Think about whether the Rules merely "permit/require" something in all situations, or if there are conditions and limitations attached. • Consider whether any one option is definitely incorrect; if even one statement is wrong, what does that mean for choice D?

✅ Before You Answer

• Look up the exact wording of Rule 6 – Safe Speed and confirm whether the phrase "safe speed" is explicitly used. • Review Rule 17 to see under what conditions a stand-on vessel is allowed to maneuver before the situation becomes critical (in extremis). • Confirm where the Rules discuss Traffic Separation Schemes and whether compliance is described as mandatory under the Rules themselves.
