I would just take drive down there, probably on a Saturday evening would be best, and see what others are doing. Me I have never had an issue with rock shores but I have always had tin boats. There is a guy who lauches where I launch and he had some kind of rubber skid put on the bottom of his boat. Might be something to look into.
