Dock

What is often thought of as a dock is actually a pier or wharf. The book Modern American Usage (edited by Jacques Barzun, et al.) defines a dock as "the water-filled space in which the ship comes to rest. The pier is the structure on which the passengers stand or alight." Would Otis Redding's song still be a masterpiece if he'd called it Sittin' on the Pier of the Bay?
