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.
