Which statement correctly describes a large-scale chart?

• A. Shows large area with less detail
• B. Shows small area in great detail
• C. Only coastal waters
• D. No scale information

Answer: (B)

Large-scale charts are used when you need a lot of detail for a relatively small area. The scale bit of a chart tells you how much ground a given distance on the map represents. A larger-scale chart shows more detail per area, so it covers a smaller geographic patch but with features like rocks, shallow areas, buoys, and shoreline contours laid out clearly. That makes it ideal for paddling close to shore where precise navigation matters. So the correct description is that a large-scale chart shows a small area in great detail. The other ideas describe charts that cover a bigger area with less detail, or claim the chart is only coastal or lacks scale information, which isn’t how large-scale charts are defined.
