You might want to consider a Dart 16. They are popualar in Europe, plastic (unbreakable) and fun. I had one, it was a good boat for both singlehanding and double. No daggerboards and kickup rudders allowed you sail over anything, and right up the boat ramp. Reefing sail and rollerfurling jib allow you to depower in a breeze. I think its better boat than a Wave or H16.
