Ticonderoga is a museum ship and one of just two remaining sidewheel passenger steamers with an intact walking beam engine of the type that powered countless thousands of American freight and passenger vessels on America's bays, lakes and rivers for more than a century. Commissioned by the Champlain Transportation Company, Ticonderoga was built in 1906 at the Shelburne Shipyard in Shelburne, Vermont on Lake Champlain.
