However, touting it as a way to "outrun" bad weather isn't really realistic IMHO. It will help you avoid some bad weather, but some storm systems crop up quickly enough, move fast enough and are large enough that they can't be avoided, regardless of whether you're in a monohull or a multihull.
I didn't mean to imply that they could always outrun weather. But specifically thinking of tropical storm systems, it seems that it is really common for their centers to move at 10-15 MPH, which is faster than a lot of cruising monos but maybe slower than some multis. Counting on outrunning everything would be a really bad plan; some of the worst storms are local thunderstorms. And no boat I know of can outrun lightening. I just meant that I think the faster boat will help you to get caught in less storms over the course of going around the world because you would have enough notice to get out of the way of a lot of them. With today's forecasting, even moving at 3-5 MPH you can get out of the way with a couple of days notice if the forecast is accurate (and despite our propensity to remember the mistakes, they are usually pretty accurate).
