You are on course 138°T. To check the latitude of your vessel you should observe a celestial body on which bearing?

Question 1 of 27070

You are on course 138°T. To check the latitude of your vessel you should observe a celestial body on which bearing?

🔍 Key Concepts

• Latitude by meridian altitude – when the celestial body is due north or south of you • The relationship between your ship’s course and the true bearing of the observed body • How an azimuth (bearing) of a body affects the information you get about latitude vs. longitude

💭 Think About

• Ask yourself: To get latitude, do I need the body to be roughly on my meridian (north-south line) or on my east‑west line? • Which choice(s) have the body nearly in line with the local meridian (000°/180°), and which are more across the bow (closer to my heading)? • If my ship’s course is 138°T, which bearing would place the body so that its altitude change tells me mostly about north-south position rather than east-west?

✅ Before You Answer

• Identify which answer(s) are close to a north-south bearing rather than east-west • Think about whether your course matters for latitude, or if only the body’s bearing relative to true north matters • Confirm which bearing aligns best with a meridian passage observation, which is traditionally used for latitude checks
