| Abstract: | The recasting of the American Nautical Almanac made all navigational texts obsolete insofar as they refer to the Almanac. To meet this situation, the authors have revised the earlier text only to the extent required to make it useful and clear in connection with the use of the new Almanac. Although a couple of tables have been inserted in the text in the formerly blank spaces at the ends of chapters that discuss subjects unrelated to the Almanac, the chapters themselves remain practically unchanged. This is, of course, as it should be, since it would be difficult to suggest improvement in the treatment of piloting and magnetic compass compensation (to select a couple of examples), and, in these fields, obsolescence is not involved. It is disappointing, however, that new developments have not been incorporated. Radar and loran are dismissed with a reference to Dutton; HO 218 is still a wartime mystery; HO 249 is ignored; despite Weems [ll and Herrick [al, the limitations of HO 211 are not clearly developed. Except for these minor criticisms, it is quite true that we have again in this revision one of the best basic texts, in marine navigation, thoroughly revised in relation to the new Almanac, and suitable either for. independent study or for use in the classroom. |
