Here you go, the question went from "hobie 16, 14 or wave" to "You should not use a hobie" <img src="http://www.catsailor.com/forums/images/graemlins/smile.gif" alt="" /> Flame wars!

The 14 is a fun little boat, but for me lacks buoyancy, At 95Kgs I'm to heavy for it. Unless you are a real featherweight don't think about going sailing with a crew. Having a jib on it helps for tacking, but otherwise just add more strings to pull, and deprive it from its simplicity.

The 16 is a fun boat. You can sail one solo up to 20 knots of wind. If the average wind in your part of the world is more than that, find a crew or get a 14.

The wave is more boring, but far more buoyant than the old design from the 14 and the 16. Less sail area as well which makes it easier to sail. And it can carry a lot of people. Not comfortably, but it will do 4 in a pinch.

Now if you want to consider other options there is a lot of them around. I don't know the aforementioned Mystere, but depending on the size of your wallet, the intended usage and your local fleet it could be a hard choice. A Stealth F16 for example cost the same as a Hobie 16 (I'm talking about new boats here, used H16 are dirt cheap, used F16 are not, yet) and gives you a much more modern boat that can be sailed solo or with a crew. A used A class could be relatively cheap as those get obsolete quite fast, and would give you crazy performance, but don't think about doing a family picnic with one.

All that to say that you do not give us enough information to help you choose: What's your budget? What is your intended use? Racing solo (get a A class), racing with a crew (get a H16), Racing sometimes solo, sometimes with a crew (get a F16), having fun at the beach with the kids (get a wave), having fun at the beach alone (get a 14 or a wave) and so on and so forth...
