Last fall when I flipped my boat over (hull up) on the trailer to store it outside for the winter I got my first good look at the bottom. I noticed someone previously filled the pad in so it was flat with what appears to be auto bondo.... why would somebody do this? It should be concave correct? Looks like I got some digging to do to find the original pad. I’m really curious why they did this, what would be the downside of a flat pad on a Ventura?
