Thanks. 5 adults is an absolute worst-case scenario. 95% of the time, it will be 2 adults, and at most we'll have 4 adults and a small child going from beach to beach. I'm hoping to stay away from an 18' because I feel that would be a lot of catamaran for a newbie to handle. But a 16' that's as stable and buyoant as possible... that's what I really need.
