Visually the photography of Christopher Little shows you what Buckley describes with words. A two member TV crew was putting together a documentary on the trip, but I don't know if that project was finalized. Buckley has some things to say about video ethics in his discussion of that project, specifically about a balance between what staging is acceptable and what goes over the line.
Most of the book is captivating, in that, "you're there" with Buckley and his crew members on the journey. However, a couple of chapters are filler. Not even Buckley with his talented gift of communication could conceal that fact. He gets tedious in describing certain maritime procedures (yawn). Otherwise, the time spent with this book is pretty well invested. On that note, he has a small section taking about people asking him as an editor to read their books, wherein he mentions that it takes anywhere from 6-16 hours to complete a book, depending on one's reading speed and the length of the work.
