My 1984 Beneteau First has a cast iron fin keel. The bottom of the keel has a void in it. The bottom of the keel currently has a flexible piece of metal (consistency of sheet metal) on it, and there is a split from front to back (again, on the keel bottom). Sorry, I don't have a picture to show as the keel is sitting on the rack and is difficult to get visual on it.

I am guessing that this void is due to galvanic corrosion. Here are a few questions:

1. Do you agree with my assessment?
2. If not, do you have any ideas what might have caused this?
3. Is this issue of a void common or very unusual?
4. For repair, should the material be ground back to the solid iron, smoothed, and then coated?

Thanks in advance for the help.

Thanks for the response. Then, maybe it isn't galvanic corrosion. Guess I'll get the angle grinder out and start exploring. I can get to some of the keel bottom to, at least, grind through the "loose" metal that looks like sheet metal. Maybe it is a piece of sheet metal.
