Yep, Like Phatdaddy just said, there are some good ones, just have to be patient. You're correct on the ability of the V20 to handle rougher water. Of course it's never going to handle waves like a 45' Trawler can, etc... but for it's size I'd stack it up against just about any other boat and I'll bet it will win every time for ride and dryness in the snot.
Take a rubber mallet with you when you go inspect the boat. Tap on the transom all over, starting at the top and working down. Listen to the sounds of the "rap". Soggy wood will make a dull muted sound while good hard wood will make a sharper report. Next, get inside the boat and walk over the entire deck, especially near the sides, feeling for any soft spots where the deck gives a little under your weight. That's a tell-tale sign of rotted wood...either under the floor or on the stringers. Good luck in your search. Good to have you aboard. If you should happen to buy that boat please post pictures ... we love boat porn here. (even if you don't buy it, we love boat porn pics)..
PS: Extend the outboard engine all the way up as far as if will go, then lean on the prop hard while looking at the transom. If you can see the transom move/flex that's a sure sign that the transom wood is rotted underneath. Walk away at that point, no matter how good the deal is, unless you're ready to fix the transom.
