Just a few.
I can think of one, that was a Jeanneau SO37 in England, no body figured it out for two weeks, took the 2nd charter person to realize something was wrong.
That is the ONLY ONE I know of for sure. I would bet a super hard grounding would do as much or more $$$ damage to a boat that is encapsulated than not. Encapsulated keels are only recent in that we had to have a fiberglass boat to pull this off. Also considering what SOME of the manufactures use for ballast vs the bolt on types.........not sure I really want lead shot in concrete poured into my fiberglass keel!
Then again, the earliest iron/lead on the bottom of a keel had to be bolted on, or rocks in the bilge or equal. many types of ballast needed thru the years. Even today, oil tankers use water in the oil tanks when going back to the oil source once empty.
