 "Adirondack" had a hull constructed almost entirely out of wood with a single expansion low pressure beam engine.She was built out of wood to give her more flexibility in pushing over the shoals of the upper Hudson River that she would spend her life traversing between New York and Albany.In a day when most ships were using multi-expansion engines the owners went with the cheaper, and simpler, single expansion engine because she would only be used for part of the year making a one-way, ten hour trip, between New York-to-Albany/Albany-to-New York a day, they felt the fuel efficiency and cost of the more complicated engines would not pay for themselves in the long run.
