Bass Tracker repair

I have a older riveted Bass Tracker 167, and the guy i bought it from was an old timer who launched the boat by himself and used the trailer to pull it back into the boat ramp. So after years of that there is a hole that was wore into the keel. What I am looking for beside the JB weld that currently plugs it, are a few ideas to fix or protect that area, any aluminum fabricators around charleston… Etc…
Thanks for the help
