Hearst Movie Yacht

I just watched the movie "The Cat's Meow". It's about William Randolph Hearst's party murder mystery aboard his yacht... does anyone know what the yacht was that they used in the movie or what his real yacht was? The one in the film looks fabulous on the outside, of course the inside had to have been studio work, but none-the-less.
