I see a lot of peaple here have jon's. I have a 12' polarkraft jon boat. Pretty narrow but a good boat. Easy to get into smaller ponds that big boats cant get to and I can tuck the boat into lillypads and other places that big boats cant. Problem is it is not very stable. Been thinking about putting a floor in it but dont want to get it to heavy! can a boat this size be turned into a real bass boat? Oh ya forgot to mention the boat didint cost me anything! father inlaw gave it to me. Only thing I did was put pedistals with swivel seats in it and buy a new trolling motor! any thoughts would be appreciated. Thanks!

I think this thread answers your questions:

I use to have one alot like you are describeing.  You could put a floor in the bottom, like some styrafome and carpeted plywood, that would help to buffer the sound.  But as far as an elevated deck I wouldn't advise it.  That could be pretty unstable.  I know that we had a few close calls with mine and that was sitting on the seats.
