I'm thinking of buying a catamarran again. I've owned two before. A Hobie 14 and Nacra 500. I'd like to move up to 18 or 20' this time. It'll mostly be for family recretion, but I might do some racing as well. There are times when I'll be on it alone or maybe just with the wife. Does the 20'er need 2 people to handle it even in light wind? I've never sailed a 20'er before, but I have sailed a Hobie 18 several times.

Also, is there a big difference in price between an F18 cat and a 20? I will be looking to buy brand new, but will consider used.
