So, since I have been out of multihulls for some years, let me ask a question. "What about this here F16 thinger?" Who are "the three manufacturers" and how do their products compare? I definitely like boats as light as possible for both solo setup and sailing, although the A Class is pricey, doesn't like wildman winds, and worst of all has no spinnaker. (For me being on a reach with a spinnaker is one of the funnest things of all in sailing.) Thanks much to all, so far, for all the detailed input!
