🔍 Key Concepts

• Intercept (Marcq St. Hilaire) method for celestial navigation • How bearing relative to your course affects longitude vs. latitude determination • Difference between a time sight for longitude and a line of position oriented mostly north-south or east-west

💭 Think About

• If your course is 061°T, in what general direction (north/south/east/west) are you heading? • For checking longitude, do you want your line of position to run mainly north–south or mainly east–west? How should the observed body be positioned relative to your track to get that? • Which choice would place the celestial body roughly abeam (off the side) of your vessel, and what does that do to the orientation of your line of position?

✅ Before You Answer

• Identify which bearing(s) are roughly abeam (about 90° from your heading) rather than ahead or astern • Consider which bearing will make your line of position best suited for determining longitude rather than latitude • Double‑check the difference between your course (061°T) and each option to see how the body lies relative to your bow
