River barges travel up and down rivers to transport heavy freight and cargo. Some barges are self-propelled while others require tugboats or towboats. You can work as a captain, where your responsibilities include overseeing the safety of the crew and cargo and assisting with daily operations. As a mate or pilot, you handle navigational duties and help steer the barge. As a deckhand, you stand watch, handle rigging and lines, and use hand and power tools to repair and provide maintenance on the ship. You can also work as a cook, a barge cleaner, an engineer, or as an oiler in the engine room.
