The best response I have to your questions is to purchase the book. The authors answered all of your questions, address the debate pertaining to sea anchors and when to use them, plus provide information from a host of veteran ocean racers, nearly all of which were extremely knowledgeable about heaving to V/S trying to outrun storms. Obviously, there is no one size fits all in the scheme of things. If this were the case no one would every get into trouble during a storm. And, if you could accurately predict a storm's path, there are some folks at NOAA that would be willing to pay you some big bucks, especially during hurricane season.
