Celestial Navigation Plotting | Simultaneous & Staggered Observations | Mate & Chief Mate Exams 🚢

Celestial Navigation Plotting — Simultaneous & Staggered Observations Explained | Mate / Chief Mate This lesson from Sailor’s Compass 🧭 teaches how to FIX a ship’s position using celestial observations — exactly the way it is asked in Mate & Chief Mate exams. You’ll learn how to convert sextant observations into accurate plotted fixes using clean, step-by-step chart work. What You’ll Learn • Simultaneous observations — two sights at the same time • Staggered observations — one body, two different times • Transferring a position line correctly • Plotting graphical combination of sights • Constructing a Mercator plot on answer sheets • Using only latitude scale for distances • Applying parallel sailing for east–west movement • Choosing scale (1 cm = 1 mile etc.) • When to transfer geometrically vs by calculation • Basics of high-altitude sights (more then 89°) Clear plotting examples are shown both on graph sheets and plain sheets.
