Which chart scale is used for Small Craft?

• A. 1:50,000 and larger
• B. 1:40,000 and larger
• C. 1:150,000-600,000
• D. 1:600,000 and larger

Answer: (B)

Large-scale charts provide more detail for a smaller area, which is essential when navigating near shore, in harbors, and through channels where shoals and aids to navigation need to be clearly seen. For Small Craft, that means using charts with a large scale, typically 1:40,000 and larger. Smaller-scale charts (like 1:150,000 or 1:600,000) cover wide areas with less detail and are used for offshore passages, not for nearshore maneuvering. So the best choice is the chart scale 1:40,000 and larger.
