Design differences

Riverboats are usually less sturdy than ships built for the open seas, with limited navigational and rescue equipment, as they do not have to withstand the high winds or large waves characteristic to large lakes, seas or oceans. They can thus be built from light composite materials. They are limited in size by width and depth of the river as well as the height of bridges spanning the river. They can be designed with shallow drafts, as were the paddle wheel steamers on the Mississippi River that could operate in water under two metres deep.

While a ferry is often used to cross a river, a riverboat is used to travel along the course of the river, while carrying passengers or cargo, or both, for revenue. (Vessels like ' riverboat casinos ' are not considered here, as they are essentially stationary.)

The significance of riverboats is dependent on the number of navigable rivers and channels as well as the condition of the road and rail network. Generally speaking, riverboats provide slow but cheap transport especially suited for bulk cargo and containers.
