High Quality Content by WIKIPEDIA articles! A riverboat is a ship designed for inland navigation. 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 on large lakes, seas or oceans. They can therefore be built from steel as well as from composite materials. Although steel is stronger, composite materials can decrease weight by up to 50% and thus decrease energy requirements, ... as well. They are limited in size by width and depth of the river as well as the height of bridges spanning the river.
