In your case NHsailor I would look at modern skeg boats, like the nacra 5.0 or nacra 500. It will suit all your wishes the best and have slighlty better upwind performance then asymmerical boat like the H16. It is also less weight sensitive.

Boarded cats are great but I don't think you really want to go that way. Often these boats are more race oriented and therefor are fitted with more and more complex systems.
