Considering a catamaran or trimaran for purchase, but have some curiuosity regarding their stability in the open ocean, as well as various weather condition.

I've heard that the cat isn't really a rough weather boat, but does this apply to the trimaran as well? What are some characteristics I should expect of each?

Which model may be good to look for? Any sugestions as far as what problem areas to consider? What's a good boat, new or used, to check out?
