What direction did the sailboats barge and tugs travel in the drawing showing ancient ships on the Nile River considering the river flows south to north with a strong northerly wind?

In the drawing depicting ancient ships on the Nile River, the sailboats would likely travel southward, using the wind to propel them against the current. The tugs and barges, which typically move cargo, would also head south, likely utilizing the wind and their own power to navigate the river's flow. The combination of the river's south-to-north current and the strong northerly wind would influence the direction and speed of their movement.
