Inland Design Differences
These vessels are usually less sturdy than ships built for the open seas, with limited navigational and rescue equipment, as they do not have to survive 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 meters deep.
While a ferryboat is often used to cross a river, a riverboat is used to travel along the course of the river, while carrying passengers and 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.

“Being blunt with your feelings is very American. In this big country, I can be as brash as New York, as hedonistic as Los Angeles, as sensuous as San Francisco, as brainy as Boston, as proper as Philadelphia, as brawny as Chicago, as warm as Palm Springs, as friendly as my adopted home town of Dallas, Fort Worth, and as peaceful as the inland waterway that rubs up against my former home in Virginia Beach.”
—Martina Navratilova (b. 1956)
“Joe ... you remember I said you wouldn’t be cheated?... Nobody is really. Eventually all things work out. There’s a design in everything.”
—Sidney Buchman (1902–1975)
“Generally there is no consistent evidence of significant differences in school achievement between children of working and nonworking mothers, but differences that do appear are often related to maternal satisfaction with her chosen role, and the quality of substitute care.”
