I noticed a boat for sale recently that had about ten blocks of what appear to be 100 pound lead billets on each side of the centerline engine. There could be more that I did not see in pictures. The lead was not on center, and it was not secured in any way to the hull. If for some reason the boat were to be knocked over, wouldn't the lead crash into or through the saloon sole, damaging everything it hits, and possibly pinning the boat upside down as what was originally on the hull in now on the cabin top? I can't imagine that this is a proper way to ballast a boat. I would think the lead should be in the keel area or at least on center provided there are no list issues. At a minimum, shouldn't ballast be secured or restrained in some fashion? I have heard more than one opinion on this. Any thoughts? Thank you. Bill
