Which chart scale is used for General charts?

• A. General (1:150,000-600,000)
• B. Sailing (1:600,000 and larger)
• C. Harbor (1:50,000 and larger)
• D. Small Craft (1:40,000 and larger)

Answer: (A)

General charts use small-scale maps that cover wide areas, so you can see coastlines, hazards, and routes over a broad region. This category typically ranges from about 1:150,000 up to 1:600,000, which makes them ideal for planning long passages and getting the big picture of a travel area. The other chart types are intended for more detailed, local navigation: harbor charts and small craft charts provide greater detail for nearshore work and harbor approaches, while sailing charts are used for coastal navigation at scales that show more area with less detail than harbor or small craft charts.
