Question 441Navigation General

The correct answer is B) general chart. A chart with a natural scale of 1:160,000 is classified as a general chart. General charts are used for coastal navigation and show a larger geographic area with less detail compared to harbor or coast charts. They provide an overview of the coastline, major landmarks, and navigational hazards. The scale of 1:160,000 is typical for general charts, as it allows for a broader view of the coastal region. The other options are incorrect because: A) harbor charts have a larger scale (e.g., 1:20,000) and focus on a specific harbor or port area; C) sailing charts are used for open-ocean voyages and have a smaller scale (e.g., 1:1,000,000); and D) coast charts have a scale between general and harbor charts (e.g., 1:80,000) and provide more detailed information about the coastline.
