The steamers were exceptionally long and narrow, designed for travel on the Penobscot River. "These fast triple-screw turbine-driven steamers were able to cut more than two hours from the Boston-to-Bangor schedule previously maintained by City of Bangor and City of Rockland," according to the authors of Eastern Steamships.
