What information does a navigational chart provide?

Navigational charts are essential tools for mariners that provide detailed information about maritime features and navigational aids. This includes crucial data on coastlines, seabed topography, important landmarks, buoys, lighthouses, and safe passage routes. The primary purpose of these charts is to assist in navigation, helping sailors understand their surroundings and identify potential hazards or navigational aids that can assist in safe vessel operation.

Weather updates and forecasts are typically found in different resources, such as weather reports and marine forecasts, rather than on navigational charts. Similarly, fishing zones and regulations are specific to fishing activities and are usually documented in separate publications or charts dedicated to fisheries management. Information about the crew onboard is not relevant to navigational charts as they focus solely on the environment and navigation rather than personnel details. Thus, option B stands out as the most accurate and relevant choice regarding what navigational charts provide.
