🔍 Key Concepts

• Rule 17 – Action by Stand-on Vessel in the Navigation Rules • Difference between a stand-on vessel and a give-way vessel in a crossing situation • What the rules say the stand-on vessel should do "in the first instance" or "normally"

💭 Think About

• Ask yourself: In a normal crossing situation, which vessel is required to maneuver to avoid collision, and which one should be predictable? • Consider why it is important for one vessel to keep doing the same thing while the other one maneuvers. • Think: at what point, if any, is the stand-on vessel allowed or required to change course or speed?

✅ Before You Answer

• Verify what Rule 17 specifically states about the duty of the stand-on vessel at the beginning of a crossing situation. • Confirm which vessel (stand-on or give-way) is primarily responsible for taking early and substantial action to avoid collision. • Pay attention to the word "normally" in the question – it refers to what the stand-on vessel should do before any risk of collision becomes critical.
