Hey Sparkey, first you own one of those rubberduckie pontoon boats, then you steal my line. SHEESH!!

Do a websearch. Lots of info. But before any info can be given, what type of boat were you looking at? Then, what rivers do you plan on fishing? Do you want to stand up and fish or simply drift from one spot to another? When you float, are you going to avoid any serious rough water or do you plan to actually do some wave riding?

Can't tell you much until have at least those answers.
