The boat, called 'Guest List,' rests about 100 feet from the home of Alicia Preston, who says no one knows what to do with it. 'That's the big problem,' Preston told the Daily News on Tuesday. 'No one is claiming responsibility for it.' The boat is registered in Newburyport, Mass., according to Fox in Boston, and Preston says she believes it was bought by someone from Brazil. Rumors were flying that the boat was being used in a Denzel Washington movie. Another rumor was that it was being used for porn.
