Thanks for the sound advice, it's certainly appreciated.
I don't think I was entirely clear, however. I have the Navy sailing club to teach me how to sail and to connect me to sailing partners. It's just that I enjoy sailing by myself and I don't want to buy a boat that I can't eventually use for that purpose.
More than anything, I'm interested in opinions about the boat itself. So far, I have only met a few catamaran sailors. They have already given me some great inputs, but I'm always looking for a broader pespective. I guess it is the Navy way ... trust but verify.
After spending some more time on the forum here, I think 1 & 2 are pretty well answered, but I would still appreciate input on 3 & 4.
