This manual explains what is presented on the nautical chart, highlights the utility of this information, describes the charting conventions used to depict features and items of interest, and provides some practical pointers on how this information is used. It is written to serve many types of users, ranging from operators of recreational vessels to those who drive "heavy iron." Abundant photographs and chart excerpts illustrate key points made in the text. All chart excerpts were current as of spring 1995. Since this manual was published, some charts may have been revised. Even if these specific charts have been revised, the general points remain valid. It almost goes without saying that these chart excerpts should not be used for navigational purposes.
