"At the end of the first decade of the century management of the Maine Central Railroad decided it wanted more class and more power for its Mt. Desert Ferry steamers and directed Bath Iron Works to produce two vessels meeting these qualifications. They were the twin steamers, "Moosehead" and "Rangeley," both 185 feet long and named after two of Maine's largest lakes.
"Moosehead came out first in 1911, with two triple expansion engines that could produce 2350 horsepower and give Bar Harbor rusticators a thrilling ride…"
"During World War I, "Moosehead" was taken over by the Navy, but after the war returned to civilian service under the name first of "Porpoise" and later "Mayflower," running between New York and Bridgeport, Connecticut…" - Penobscot Bay, Mount Desert and Eastport Steamboat Album by Allie Ryan, p. 5 & 32 - 1972.
