What is a flatboat look like inside?

Inside a flatboat, the space is typically open and utilitarian, designed for cargo and transport rather than comfort. The deck is generally flat and spacious, allowing for the loading of goods such as lumber, agricultural products, or livestock. Depending on the design, there might be a small area for the crew, possibly with basic sleeping quarters and storage for supplies. Overall, the interior emphasizes functionality to accommodate the needs of river navigation and trade.
