🔍 Key Concepts

• Great-circle vs. rhumb line (loxodromic) sailing on long ocean passages • How a gnomonic chart represents great-circle tracks and how distance is actually measured • Definition and location of a vertex on a great-circle track, especially for trans‑Pacific routes

💭 Think About

• Look at how the great-circle track from San Francisco toward 13°00'N, 125°30'E bends on the gnomonic chart. Does it pass north or south of key island groups like the Bonins? • Ask yourself where, in longitude, a trans‑Pacific great‑circle from the U.S. West Coast to the western Pacific typically reaches its highest latitude (the vertex). • Think about whether distance on a gnomonic chart is measured along meridians (longitude) or parallels (latitude), and at what point (tangency vs. mid‑latitude) you transfer to a Mercator chart for measuring distance.

✅ Before You Answer

• Confirm how distance is properly measured when using a gnomonic chart together with a Mercator chart for ocean routing. • Identify whether the vertex of the great‑circle track for this route lies in the Northern Hemisphere and whether your entire planned track lies to one side of it. • Check the relative position of the Bonin Islands to the plotted great‑circle track: do you actually need a composite route to avoid them, or does the normal great‑circle already pass clear?
