Support for Introduction to Electronic Chart Navigation
Note 1. To quote from Section 2.9 on Lights
What we forgot to add to the book is the defintion of nighttime. We find this in S-57, Section 18.104.22.168
Night lights are lights that are normally exhibited from about sunset to about sunrise, they are encoded with EXCLIT = 4 (night light).
Note 2. In passing we recommended downloading NOAA's US Chart No.1 to your phone, but that is not quite so transparent an operation without practice, and it is browser dependent. The problem is the pdf opens up in the browser and not all mobile devices have a way to save it.
One solution is download it on a computer and then mail it to yourself and the mail program will do the interfacing for you—that is, it will ask how you want to open the attachment. Then choose to open in Kindle or Apple Books. (If you do not have one of those readers, they are all free downloads.) These readers then store it in their resprective libraries, and then you can make your own organized bookmarks and annotations, and it is easy to get to. There are no bookmarks in the original. The graphic index is the last page. With Apple products, Air drop is often an effective way to move files to a mobile device.
Note 3. We have an article online with links to Free ENC Viewers that can be used to read these charts and learn about them.
Note 4. Here are a couple packages of echarts for practice. Each set includes both RNC and ENC.
Note 5. New online course devoted to ENC that uses this book as the text: Electronic Chart Navigation
