The last large side-wheeler steamer used in New England for both passenger and freight service was the 214-foot J. T. Morse, built in 1903-04 in East Boston for the Eastern Steamship Company. Powered by a 600-horsepower, single-beam engine, it traveled the Rockland, Maine to Bar Harbor run from April to October or November each year.
The ship was named for James Thomas Morse of the well-known maritime (shipping and towing) family from Bath, Maine.
