What must a pilot do to steer the steamboat upstream?

To steer a steamboat upstream, a pilot must adjust the engine's power to increase thrust against the current, use the rudder to navigate and maintain a straight course, and closely monitor the waterway for obstacles and changing conditions. The pilot may also need to employ techniques such as "crossing the current" or positioning the boat at an angle to effectively manage the flow of water. Additionally, understanding river patterns and utilizing any available slack water can help in maneuvering upstream efficiently.
