I agree that a Hobie 16 is a good base to start at because you can sail on that boat for years to come. Not hard to sail, but a hard boat to sail well. The H16 also has the class, parts, and durability that is perfect for a new cat sailor (or any sailor). However, you will definitely need a crew with you when you sail in anything over 14 mph winds (you'll be overpowered). I might also suggest for your weight a Hobie 14 turbo. They don't handle too much weight well, but if you are going to have another small crew, then I would almost go for that. The Hobie 14T is an absolute blast when its blowing 25+. I think unless you had an experienced heavier crew, that the Nacra 5.2 is too much for a new cat sailor to handle.
It also depends on what price range of a boat you are looking for. (Hobies and older Nacras are cheapest)
I wouldn't suggest a Hobie Wave because you will grow out of it in a year when you want something with more strings and speed
Just my 2 cents
Any other questions, just ask, we've all been through deciding on that first boat
