If you change course at 0420, what is the course to make good to leave Twenty Eight Foot Shoal Lighted Buoy abeam to port at 1 mile?

🔍 Key Concepts

• Course to make good vs. heading on the charted track line • Using abeam bearing (90° off your course) to pass a buoy at a set distance • Plotting a new course from time of course change (0420) to meet the desired abeam position

💭 Think About

• On your chart, from your 0420 position, how would you draw the line so that the buoy will lie exactly 1 mile abeam to port when you are closest to it? • What relative bearing (in degrees) does "abeam to port" correspond to, and how does that relate to your true course line? • When you slide your parallel rulers from the track line you want to the compass rose, which true course do you read off?

✅ Before You Answer

• Be sure you are using true bearings and true courses, not magnetic or relative values • Confirm that the buoy is 1.0 NM away at the point of abeam, not at your course change point • Verify that your plotted line keeps you clear of the shoal and passes with the buoy 90° on your port side at closest point of approach
