ASA 103 is a detailed version of what is ASA101. It still lacks the update it needs for modern sailing practices as some rules or practices no longer applies. Best for those seeking to gain their ASA103 certifications

This is a great book content-wise. It contains excellent information that is helpful and easy to understand with review questions periodically to reinforce important points. If you know this book, you will pass the ASA103 test. It is not formatted as an iBook, however. Highlighting, note-taking, changing font size, and other features that make iBooks great for reference books and text books are not supported in this version. It would be a 5 star rating if this book was formatted correctly.

Highlighting is not supported when reading this volume in iBooks. I verified that highlighting was working properly in my iBooks app by testing it on other books, where it works fine. It’s only on this book that highlighting doesn’t work, and it doesn’t work on my Mac or on my iPad.
