I am sure there are some Freepers that will post a good charity. That being said, years ago.. my husband and I donated a used boat to a charity. They even came to the house and picked it up... all the paperwork was in order. We took it off our taxes as was allowed. A few years after that, we received a call from a man in D.C. who “found” the boat and wanted us to sell it to him. We explained the boat had been donated and no longer ours. DNR contacted us and asked us to sell the boat to this “nice man” and again, we explained we can’t sell something we don’t own. (they found us via the boat number like a VIN on a car). Some years after that, we were called by a person who retrieved the boat (a tow service) from the Bay... advising us he would send his bill (a completely different person). Once again... we explained it had not been our boat for 10 years. Long story short, we personally would no longer donate a boat/car etc... the type of people who pick up the items are not the most trust worthy. FWIW, the charity was one of the top organizations that handled donated cars, trucks, boats etc... TBH, it wasn’t worth all of the threats of civil actions etc... to us.
Sounds like your boat had a lot of adventures!
