I think the Prowler 13 is a great choice myself. I'd be surprised if you had a problem with the scuppers breaking through. I guess it depends on how much you running over sharp rocks and how heavy you are. It should be covered under warranty for awhile, if your really worried about it maybe you can get an extended warranty. I know some places that have repair kits for holes in the hull and it's not too hard to make repairs, so /I wouldn't worry about it too much. You might do well to limit your contact with the rocks anyway to limit scratches and gouges. I usually can stop before plowing into them by sticking my feet out and using them to stop when coming into shore for a landing.
