Doug,
CONGRATULATIONS.... I'm not the one to help you since I live in exactly the opposite corner of the US but I'll be glad to chime in every once in a while with something I did wrong so you can learn from my mistakes.
There are A LOT of nice folks on this website who can help you along the way. I was a new NACRA owner this past spring and I spent some time reading quite a few of the old posts from people just like us who are new to catamarans. IT really helped alot. For instance, there is a pretty recent thread of a guy who is starting a rental business near you. You could stop by his operation and bend his ear I'm sure or just stop by to watch how he sets his Nacra up. The Nacra assembly manual is far from complete and I got more information from this website than from Performance materials. Overall, take it slow, ask questions when you have them and feel free to email me directly and if I can help I will.
Good Luck
Greg
