The custom yacht is called "The Left Hand". The boat was used to trap the crooked congressmen.
The yacht party is one of the highlights of the film, with Pacino’s Lefty bitterly watching – “with my eyes, I see it!” – as his protege Donnie drifts toward rising mob capo Sonny Black. Joe/Donnie celebrates in style aboard the yacht, drinking whiskey neat and hobnobbing with mob bosses and t0pless dancers.
