depends what you mean by rough.. I have never had any issues.
I have 12'....36" floor Crestliner, love it. I would definitely get a 36" floor, 32" is not enough in my opinion. Extra 4" helps with stability. I usually fish in my boat alone as doing the two rod chronomid dance in BC.. with that said 2 guys can be done, just a little tight with gear. If you are going to fish with two in the boat majority of the time I would consider going to a 14'... you are however of course adding weight which can be a downside. Something to consider if you are putting on the roof of your truck or have a trailer.
Either way best way to still water fish, you won't be sorry if you pick one up
