Which nautical charts are intended for...

🔍 Key Concepts

• Different chart scales and what they are used for (small-scale vs large-scale) • How sailing, general, coastal, and approach charts differ in area covered and level of detail • The phrase "coastwise navigation outside of outlying reefs and shoals" and what distance from land that usually implies

💭 Think About

• Which type of chart is usually used farther offshore for general route planning along a coast, rather than for close-in piloting? • Which chart type provides more detail: coastal charts or approach charts, and which one would you expect to use right near harbors and channels? • Does "outside of outlying reefs and shoals" suggest you are very close to hazards and harbors, or a bit farther away on a more open-water coastal passage?

✅ Before You Answer

• Match each choice with its typical scale and purpose (ocean passage, coastwise, harbor/approach). • Be sure which chart type is used for near-harbor approaches vs for offshore/coastwise legs. • Confirm which chart series is designed specifically for coastwise navigation along shorelines rather than for harbor piloting or long transoceanic planning.
