A participant in the D-Day landing in Normandy during World War II, this Liberty Ship freighter is one of two such vessels still in working order. On board you can peek at the crew's living quarters and the officers' mess hall. The large display of the Normandy invasion, one of many exhibits on board, was a gift from France. To keep the 1943 ship in sailing shape, the vessel—powered by a steam engine that appears in the film Titanic—takes a trip on the bay a handful of times each year.
