Rick and Chris Nolan of Boston Harbor Cruises bought Provincetown I in 1981, renamed her Commonwealth and used her as a tour boat. In 2000, while the Nolans were partnered with the Big Dig contractor Modern Continental, the company began service to Provincetown on Salacia, a twin-hulled aluminum catamaran with standing-room capacity for as many as 600. Like Bay State’s fast ferries, she was designed by Incat Crowther and built by Gladding-Hearn Shipbuilding. Salacia is named for the Roman goddess of salt water. The boat is 146½ feet long — amazingly, only half the length of the steamships that once plied the Boston-Provincetown route — and draws less than 6 feet, a considerable advantage in this shallow harbor. She can travel up to 40 knots, powered by four Caterpillar engines.
