What information does Pub 150 provide?

Pub 150, also known as the "World Port Index," provides essential information about ports around the globe, including their geographical coordinates, characteristics, facilities, depths, services, and associated navigational information. This publication is invaluable for mariners and navigators, as it serves as a comprehensive reference for understanding the specific details of ports, facilitating voyage planning and safe navigation.

While standard commands are vital for effective communication in maritime operations, they are not the focus of Pub 150. The International Code of Signals relates to communication at sea, providing a framework for conveying messages between vessels and shore stations, but it is distinctly separate from the port-focused information in Pub 150. Astronomical data for navigation, which includes celestial navigation elements like star rise/set times and lunar phases, is found in other publications, such as almanacs, rather than in the World Port Index.
