🔍 Key Concepts

• Rule 7 – Risk of Collision (Navigation Rules) • Use of compass bearings, radar (if fitted and operational), and systematic observation • How multiple methods together improve collision-risk assessment

💭 Think About

• Which choice or choices describe recognized methods under Rule 7 for assessing risk of collision? • Does Rule 7 emphasize only one preferred method, or using all available means? • How do visual bearings and radar information complement each other when judging if another vessel’s relative position is changing?

✅ Before You Answer

• Verify in Rule 7 that unchanged or nearly unchanged compass bearing is a strong indication of collision risk • Check whether Rule 7 specifically mentions long-range scanning and systematic observation of radar plots • Confirm that Rule 7 requires using all available means appropriate to the prevailing circumstances and conditions
