🔍 Key Concepts

• Rule 17 – Action by Stand-on Vessel (what may you do vs. what must you do) • Meaning of “so long as” you can avoid collision by the actions of the give-way vessel alone • Relationship between risk of collision and when the stand-on vessel must finally take action

💭 Think About

• Ask yourself: Does the Navigation Rule give you a specific distance, or does it describe a condition related to collision risk and the other vessel’s actions? • Think about the point at which simply maintaining course and speed is no longer safe, even though you are the stand-on vessel. • Which choice describes a condition (something that changes with the situation) rather than a fixed range number?

✅ Before You Answer

• Verify in Rule 17 (Action by Stand-on Vessel) exactly how long the stand-on vessel is allowed to maintain course and speed. • Check whether the rule ever mentions specific distances like quarter mile or half mile, or if it talks about when collision can be avoided by the actions of the give-way vessel alone. • Confirm which option matches the rule’s wording about the moment you are required to act, even as the stand-on vessel.
