This has the possibility of becoming one of those threads about "Do you want to model the vessel that was in the movie, or the vessel that it was trying to portray?"
But in this case, it isn't HMS Rose and HMS Surprise. :-)
Prof. Tilley gives us a good idea of the lack of reference material for the real Enterprise.
In the movie, the brig Lady Washington stood in as the Enterprise. You can find photos and some rudimentary drawings of the Lady Washington at http://ladywashington.org/.
Lady Washington, acting as Enterprise (also starring as HMS Interceptor in Pirates of the Caribbean - Curse of the Black Pearl), is a beautiful, and active vessel. When not in front of a camera, she sails up and down the West coast, providing sail training cruises for folks and ladling out a heaping dose of education about the days of sail. You should get a lot of atmosphere from their website.
