Cal Maritime Navigation Test One Practice

Sailing Directions are published in two main parts: Planning Guides and Enroute volumes. The Planning Guides cover voyage planning material—overview of regions, recommended routes, pilotage considerations, and general coastwide features—while the Enroute volumes provide detailed navigation information for specific coastal areas, including approaches, hazards, currents, tides, and port entries. The combination of five Planning Guides and 37 Enroute volumes reflects how this publication group is structured for both planning ahead and navigating step by step along coastlines. Other publication groups serve different purposes and don’t follow this Planning Guide plus Enroute split, which is why they don’t fit the given description. Therefore, the group described is Sailing Directions.
