Bottom Painting: What are your thoughts on this? I am buying a used boat and have seen a few models of the same boat, one which has been painted and one which has not. I intend to trailer it, but may want to put it in a slip at some point (which would make this moot) They are varied greatly in price due to extras, electronics etc. The less expensive one has the bottom painted. What effect does this have on the life and/or performance of the boat? Does it slow the boat down? Do you need to do this eventually, regardless of whether you trailer your boat?
