51 CHAPTER 4 NAUTICAL PUBLICATIONS INTRODUCTION 400. Definitions The navigator uses many information sources when planning and conducting a voyage. These sources include notices to mariners, sailing directions, light lists, tide tables, sight reduction tables, and almanacs. Historically, this in- formation has been found in printed publications; increasingly, it is being integrated into computer-based electronic systems. The navigator must know what infor- mation he needs to navigate his ship safely and how to obtain it. This chapter will refer only to printed publications. If the navigator has access to this data on an electronic data- base, only his method of access will differ. The publications discussed here form a basic navigation library; the naviga- tor must also obtain all supplementary materials required to navigate his ship safely. 401. Types And Sources Of Publications While voyage planning and navigating, a mariner must refer to both texts and tables. Examples of text include sail- ing directions, coast pilots, and notices to mariners. Examples of tables include light lists and sight reduction tables. Navigational publications are available from many sources. Military customers automatically receive or requi- sition most required publications. The civilian navigator obtains his publications from a publisher’s agent. Larger agents representing many publishers can completely supply a ship’s chart and publication library. NAUTICAL TEXTS 402. Sailing Directions Defense Mapping Agency Hydrographic/Topographic Center Sailing Directions consist of 37 Enroutes and 10 Planning Guides . Planning Guides describe general fea- tures of ocean basins; Enroutes describe features of coastlines, ports, and harbors. Sailing Directions are updated when new data requires extensive revision of an existing text. These data are ob- tained from several sources, including pilots and foreign Sailing Directions. One book comprises the Planning Guide and Enroute for Antarctica. This consolidation allows for a more effec- tive presentation of material on this unique area. The Planning Guides are relatively permanent; by con- trast, Sailing Directions (Enroute) are frequently updated. Between updates, both are corrected by the Notice to Mariners . 403. Sailing Directions (Planning Guide) Planning Guides assist the navigator in planning an ex- tensive oceanic voyage. Each of the Guides covers an area determined by an arbitrary division of the world’s seas into eight “ocean basins.” This division is shown in Figure 403. A Planning Guide’s first chapter contains information about the countries adjacent to the applicable ocean basin. It also covers pratique, pilotage, signals, and shipping reg- ulations. Search and Rescue topics include the location of all lifesaving stations.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
