Query: Don't waste your money

Don't waste your money, and by all means, don't follow his heavy weather advice, which is written as a fictional account of a small sailboat in a storm -- cutting loose a Jordan Series Drogue and surfing down massive waves a la Moitessier is just ridiculous. It has to be fictional because it's obvious Vigor never did it himself -- after all, he's still alive.Not only is his advice ridiculous, it's dangerous. Read works by real sailors like Hal Roth, Bernard Moitessier, Pete Goss, Richard Henderson, Beth Leonard, and Lin and Larry Pardey if you want to learn about sailing. Their recommendations are based on actual experience, not fictional accounts. But remember that many of their works were written before the Jordan Drogue was invented. So, for instance, just because Moitessier didn't mention it, doesn't mean he wouldn't recommend it today if he were still alive.
