Question 1 of 27070

BOTH INTERNATIONAL & INLAND To determine if risk of collision exists, a vessel which is fitted with radar must use which observation technique(s)?

🔍 Key Concepts

• Rule 7 – Risk of Collision in the Navigation Rules • The difference between detection, assessment, and confirmation of risk when using radar • How visual bearings and radar information can complement each other when available

💭 Think About

• Ask yourself: Does the rule say a radar‑equipped vessel must rely on just one method, or use all available means to determine risk of collision? • Which option(s) help you decide not only that another vessel is present, but also whether your relative bearing is changing or constant? • Think about how you would practically confirm risk of collision at sea at night or in restricted visibility—what tools would you realistically use together?

✅ Before You Answer

• Re‑read Rule 7(b)–(c) and note what is specifically said about radar equipment and radar plotting. • Consider whether compass bearings alone satisfy the requirement for a radar‑fitted vessel under Rule 7, or if the rule expects more. • Check which choices are methods of observation versus a specific instrument or sensor, and how the rule phrases that obligation.
