I realize this will start another debate in this thread but...
I think you would find, based on your info, the Baja Outlaw (Cuddie) or Islander (Open Bow) a great option. The 25-26 Outlaw is a very popular boat that I have never heard a bad thing about. Infact we owned a 272 Performance that was basically a very similar boat but with swim platform molded in instead of bolted on.
Otherwise I think a Crownline is also a great option and since I boat on the Mississippi river as well I know you can find some great examples of both there.
My 2 cents
