🔍 Key Concepts

• Relative bearing vs. course (true/pgc) and how to convert the relative bearing into a true bearing of the light • The right‑triangle formed by your track, the line of sight to the light, and the desired passing distance abeam (2 NM off) • Basic trigonometry to relate current range (7.4 NM), desired CPA (2 NM), and the course alteration needed

💭 Think About

• First sketch your present course line (214° pgc), mark your ship’s position, and plot the light at 7.4 NM, 9° on the port bow. What is the true bearing of the light from you now? • If you want to pass 2 NM abeam leaving the light to port, where is that CPA point relative to the light (directly north/south/east/west or some other direction)? Draw that on your plot. • Using the present position and the desired CPA point, what is the track line you must follow? What true/pgc course does that track correspond to?

✅ Before You Answer

• Be sure you are treating 9° on the port bow as a relative bearing from your heading of 214° pgc, not as a true bearing by itself. • Check that the distance from the light to the CPA point on your new track is exactly 2.0 NM, not more or less, when you finish your geometric or trig construction. • Confirm that your chosen course is a single steady course from your present position to the CPA point — no intermediate course changes allowed.
