The promenade deck is a deck found on several types of passenger ships and riverboats. It usually extends from bow to stern, on both sides, and includes areas open to the outside, resulting in a continuous outside walkway suitable for promenading, (i.e., walking) thus the name. On older passenger ships, the promenade deck was simply the top outside deck below the superstructure, and was enclosed by a railing. Lifeboats are typically kept on davits accessible from the promenade.
