Sailing Directions , both "Planning" and "Enroute", guides are published by the National Geospatial-Intelligence Agency (NGA) under the authority of Department of Defense. These are best thought of as Coast Pilots for non-U.S. waters.
Sailing Directions (Planning Guide) are intended to assist mariners in planning ocean passages and to eliminate duplication by consolidating useful information about all the countries adjacent to a particular ocean basin in one volume.
Each publication is divided into geographic areas by country or ocean and includes detailed information about the electronic navigation, recommended routes, traffic separation schemes, buoyage system, currency, government, holidays, industries, languages, territorial waters, time zone, US Embassy and other pertinent subjects.

Sailing Directions (Enroute) provide detailed coastal and port approach information covering the harbors, coasts, and adjacent waters which supplements the largest scale chart produced by the National Geospatial-Intelligence Agency.
Each publication is divided into geographic areas called sectors and includes detailed information which cannot be conveniently shown on a chart. Each sector contains information about the coastal winds, currents, ice, dangers, geographic features and ports, channel descriptions, anchorages, facilities, and regulations.
