Question 1 of 27070

You are planning a voyage from Godthab, Greenland, to Cayenne, French Guiana. Using chart WOXZC 5274, determine which statement is TRUE.

🔍 Key Concepts

• Relationship between great circle and rhumb line when two positions are nearly on the same meridian (same longitude). • How vertices of great circles behave on gnomonic or Mercator charts. • Correct method of measuring distance on standard navigation charts (what line on the chart you use).

💭 Think About

• Compare the longitudes of Godthab and Cayenne on the chart. Are they very different, or nearly the same? What does that imply about the shape of the track between them? • Think about a meridian (line of longitude). Is a meridian itself a great circle, a rhumb line, or can it be both in a special case? • Ask yourself whether long ocean passages always make the great circle track "considerably" shorter, or if that depends on the orientation of the route.

✅ Before You Answer

• Verify the difference in longitude between the two ports on WOXZC 5274. • Recall that the vertex of a great circle is where it reaches its highest or lowest latitude; check if that concept even applies when the track is essentially north–south. • Confirm how distance is normally measured on Mercator or standard ocean charts: along a meridian scale of latitude, not some special line at a “point of tangency.”

Question 1 of 27070

You are planning a voyage from Godthab, Greenland, to Cayenne, French Guiana. Using chart WOXZC 5274, determine which statement is TRUE.

A great circle track will be considerably shorter due to the length of the voyage.

Godthab is located at the Northern Hemisphere vertex.

The rhumb line track approximates a great circle track.

Distance is measured by using the length of meridian at the point of tangency.
