Pilottown serves as a temporary home for members of the Crescent River Port Pilots' Association and as a base for oil exploration. Although the captain is always responsible for his ship, all oceangoing ships must take a pilot on board when entering the Mississippi River system. The river has shifting passages and sand bars that make the journey difficult, especially given the tides and the powerful current downriver. The Associated Branch Pilots supplies river pilots for ships traveling between the Gulf of Mexico and Pilottown. The Crescent River Port Pilots' Association supplies river pilots between Pilottown and New Orleans, Louisiana, and the New Orleans-Baton Rouge Steamship Pilots Association supplies pilots for ships that are bound for Baton Rouge, Louisiana.
