How would a Mississippi riverboat captain’s dream ship have looked in 1870? For David De Haven of New Orleans, it would have featured spiral staircases, arched passageways, private promenades for the ladies and one for “gents,” and luxury cabins opening into sky-lit rotundas. "Water closets" for passengers were to be tucked behind the two towering side wheels. Captain De Haven submitted his drawings to the U.S. Patent Office and received a patent for the innovative floor plan in 1870. Although the designs and accompanying text are part of the U.S. PTO’s online database, they cannot be retrieved through a simple Google search.
