i have a 14 foot v-bottom with a 28 that does fine with 3 people on it. backbays typically don't get to rough. just need to watch sometimes for the bigger boats that like to speed through the backbays and drive past you at 10 yards. Its the greatest when you are in ludlum bay and speed right through the fleet
I miss taking my sneak box (12') out in the back bay fishing in the summer. You can get to all kinds of great spots, you can find places to get out and wade(when it's warmer), and you don't need to worry about company where you will go.
