Question 442Navigation General

The correct answer is D) coastal chart. A coastal chart typically has a scale between 1:50,000 and 1:150,000, which includes the 1:80,000 scale mentioned in the question. Coastal charts provide navigational information for coastal waters, including shorelines, navigation aids, and other features relevant to coastal navigation. The other options are incorrect because: A) general charts have a smaller scale (typically 1:1,000,000 or smaller) and cover larger geographical areas, B) sailing charts are used for open-ocean navigation, and C) harbor charts have a larger scale (typically 1:20,000 or larger) and focus on specific harbor areas.
