I ran into this book after I saw a reference to it online. Seemed like a joke at the time, until I read it. Actually, it's perfectly serious. As the previous reviwer noted, this book was "written by an old captain who was tired of running over fools in their pleasure boats, and wanted to educate those same fools in a futile effort to save their lives". Very apt description. As a more or less novice to boating, it never really ocurred to me that (make that "I never thought about it") most small pleasure boats that go a reasonable distance offshore are actually far slower than large merchant ships and thus can get overtaken and rundown quite easily. Oooops. And large merchant ships might not even notice. Bigger Ooooppps.
So the author very kindly wrote a complete book about how not to get run down. I found it very informative and if I ever do get far enough offshore that I'm getting into commercial shipping lanes, I'll be studying this book a lot more seriously. Well worth the read if you're an offshore sailor/boater.
