This happens all the time with private LLCs and S-corps that do nothing but own boats, planes, equipment, or other stuff where sales or use tax is supposed to be paid on transfers.

You don't sell the boat, you sell the LLC that happens to own the boat. And when buying a business entity or business interest, you don't pay sales tax. The boat was always owned by the same LLC, it never changed hands - it was the business that changed hands.
