Why do barges push instead of pull?

Tugboats can be seen out in the ocean or in narrow rivers, but it might be hard to spot them because they are so small compared to most other ships. They help move other ships by pushing or pulling them, and might be used to push another boat that has had engine problems and cannot power itself forward anymore.

Tug boats are used to maneuver large ships in harbors and bays. They are also used to pull barges using long tow lines.
