Sailing charts are scaled to _____ size and smaller?

• A. 1:50,000
• B. 1:600,000
• C. 1:100,000
• D. 1:1,000,000

Answer: (B)

Scale on charts tells you how much ground one unit on the chart represents and how much detail is shown. A smaller scale means you can see a larger area, but with less detail, while a larger scale shows a smaller area with more detail. Sailing charts are designed to cover broad areas of coastline and nearby waters, so they use a small scale to give you wide coverage. Among common options, a scale around 1 to 600,000 fits that purpose: it supplies enough navigational information for coastal and near-shore sailing while spanning a wide area. Larger-scale options like 1 to 50,000 or 1 to 100,000 would show far more detail but only over a small area, and a 1 to 1,000,000 chart is even more generalized; it’s less practical for routine sailing but can be used for very broad planning. Therefore, 1 to 600,000 is the best choice for sailing charts.
