Re: Helms 25 Centerboard restoration
The right way to fix this would be to drop the center board completely by knocking that pin out. It does not look like a fun job though as your center board is pretty rusty and looks heavy. At least this way you will be able to inspect the top of the center board where it pivots on the pin; it may be badly worn/rusted as well.
Using an angle grinder and various grinding wheels you should be able to clean up much of the surface rust. You will likely need some welding done to repair the lower attachment point that seems to be where the missing chunk is on the trailing edge.
The entire metal board could then be treated with Ospho or Naval Jelly to stop the rust.
Using epoxy some cloth and fillers you could then coat the entire thing in fiberglass.
It would not be as good as a new $2500 center board but it would likely last quite a while if done properly.
