The essential reference tool for reading maps, published by the Coast Guard, is now available to boaters in an attractive, colorful edition that includes important supplementary information about navigation. A must-have for all mariners, the first half of the manual reproduces the U.S. Coast Guard book, with coverage of basic chart concepts, the anatomy of a chart, how to read a chart, symbols and abbreviations associated with National Ocean Service and Defense Mapping Agency charts, and the chart numbering system. In addition, for extra value, the USCG version has been expanded to include navigation tips and techniques from Chapman Piloting and Seamanship, 64th edition, including details on positioning procedures, dead reckoning, and river piloting.

As in previous editions, the symbols used on paper nautical charts produced by NOAA and the NGA and digital raster representations of those charts, such as NOAA Raster Nautical Chart (NOAA RNC's), are presented in lettered sections organized in categories, such as Landmarks, Depths, and Lights.
