I remember reading Wharrams Two Girls, Two Catamarans, etc years ago but I may not have kept up. When I was saiing in Hawaii in '80 I saw one of his catamarans but had the sense that unless you lived somewhere between 23* north and 23* south it wouldn't be as much fun. Nonetheless, I always enjoy boats of that genre, hence my looking at the site in question. Innovations seems in general to go up the ladder of technology and seldom down it. Thanks again.
