Question 516Navigation General

The correct answer is A) The topics for warnings included in HYDROLANTS, HYDROPACS, and NAVAREA warnings are the same. This is correct because HYDROLANTS, HYDROPACS, and NAVAREA warnings are all part of the World-Wide Navigational Warning Service, which is coordinated by the International Maritime Organization. These warning systems cover the same types of navigational hazards and information, though they are issued for different geographic areas. The other options are incorrect because: B) The United States is responsible for NAVAREA warnings in a different area, C) NAVAREA warnings cover offshore as well as coastal navigation, and D) these warnings are typically broadcast via digital means rather than voice.
