Movie Yacht Quiz

Hi All , I was just watching the movie "Donnie Brasco " last night and they had a really neat yacht (around 110') on it which in the movie was called "The Left Hand" I can't find any reference of this yacht anywhere. Does anyone know what the yacht was. The yacht was supposedely used by the "Abscam" sting, which did happen in real life. Does anyone know what yacht the Feds used for the Abscam sting ?

P.S. I also looked up the yacht that was used in the movie" Catain Ron" with Kurt Russel, turned out to be a 51' Formosa.
Geeze , it looked a lot bigger on the screen.
