Why would a steamboat be superior to a flatboat?

A steamboat would be superior to a flatboat primarily due to its ability to navigate upstream and maneuver more easily against strong currents, thanks to its steam-powered engine. This capability allows for faster travel and greater cargo capacity, enhancing trade efficiency. Additionally, steamboats can operate in a wider range of water conditions and are less dependent on wind or human power, making them more reliable and versatile for transportation.
