I duck hunt a very large body of water that barges run constantly. It gets very rough and then add in the prop wash from the barges and it can get hairy. I avoid most of it by running close to the bank, but I have hit some pretty big white caps head on and never has the boat shown signs of waving let alone collapsing. Now, having said that, I would be very nervous if I hadn't braced it like I did. Just a floor after taking the center bench out.....on a small farm pond only. Brace it up and use some common sense when running around the lake and it is perfectly safe to me.
As I said, I duck hunt out of the boat and that center seat gets in the way when in waders. I also do a lot of jug fish by myself and every now and then you have to cut the motor and make a run for the front of the boat. With a center seat it can get hairy when you are concentrating on a jug. For my style of fishing and hunting, it made sense. If you aren't comfortable with it then don't do it. In the end, the boat is supposed to bring you pleasure and if you are as nervous as a virgin at a prison rodeo every time you take it out you won't enjoy it. Just know that there are safe ways to do it if you want to.
