Re: Keel: a.k.a Water Bucket
Yes the color of the water is strange, even with a lead keel if it had been in there very long it would be mucky. I would be worried about any structure that may have been damaged with freeze thaw cycles as well. Remember it is the fiberglass that is holding the casting (be it Iron, concrete lead or some mix) onto the boat. So if the fiberglass got damaged by freeze thaw it could in theory let the keel ballast go.
