Re: When it's time for boat heaven...
I think that there are many boats out there which need to be scrapped due to their condition (too expensive to restore, serious structural problems). Salvage any useful items, including keels (lead scrap is 75 cents a pound!), cut up the hulls (concrete cutting saw will do it fast and cheap when dealing with thick hulls), or if they can be floated take them out into deep water and sink them. Have done it to a couple of smaller boats I could not sell. Got more for parts than I was asking for the whole thing.
Be kind, for everyone you meet is fighting a hard battle.
