I wouldn't go to sea without it.

It's tempting to think that your tablet or smartphone can provide all the info the cruising yachtsman needs these days, but cellular coverage just isn't good enough for one thing, and of course an electronic device (particularly in a hostile environment) can stop working too easily. So this book is part of my basic navigator's kit. It has all the info you need and not a lot else. Perfect.
