Suggestion for the next version: do a singlehanded-multihull version.
As you can tell from my book, I am very performance oriented. I really believe in pushing the boat to the limit. So every time I see another story about a big tri flipping, I am confirmed in my thought that multihulls are just not built for singlehanding. They flip too easily and once they flip, there is no option but a rescue. This goes against my entire philosophy that singlehanders should be self sufficient. I remember a trans-Atlantic race some years ago where 40% of the boats flipped. To me this is just nuts. Didn't another big 80' multihull just flip a couple of months ago? It happens so often that I just ignore them now.
I know that there are big, stable multihull cruisers out there, but they are not really in my frame of mind with the book that is more performance oriented. In one part of the book I mention how unreliable boat engines are. I received a comment from a multihull cruiser that he has motors on both of his hulls, so he doesn't worry about one quitting. TWO MOTORS!!! Give me a break. We are sailors, not motorists.
I really believe that the future of singlehanding lies in canting keels with dagger boards, or the Dynamic Stability System wing that sticks out the side and nearly makes the boat into a multihull. In the new version of the book, that will be published on real paper by International Marine next fall, I've added a whole chapter on the subject of keels that covers both of these in detail. So just wait until the fall and you will see what I've come up with.
