Which statement best describes the difference between large-scale and small-scale charts?

• A. Large-scale charts show large areas with less detail
• B. Small-scale charts show small areas with great detail
• C. Large-scale charts show small areas in great detail
• D. Small-scale charts cover large areas with less detail

Answer: (C)

Scale on charts tells you how much ground is shown and how much detail is included. Large-scale charts zoom in on a small area and reveal a lot of detail—rocks, shoals, channels, buoys, and shoreline features—which is exactly what you need when paddling close to shore or navigating in harbors. Small-scale charts, by contrast, cover large regions and sacrifice fine detail to show a broader view, which is handy for planning long trips but not for close-in navigation.

So the best statement captures this relationship: large-scale charts show small areas in great detail. The other options describe either the wrong relationship for large-scale (covering a large area with less detail) or only restate a property of small-scale charts without noting how scale contrasts with the large-scale view.
