Boats have a number of advantages. They are relatively inexpensive to operate, and reasonably quick for short distances. They can take many people or a large amount of cargo. However, riding in them becomes rather unpleasant when the weather is bad, and sometimes even dangerous. For long distances, they are a bit slow. Boats are the clear choice for cargo, and for transporting passengers over short distances. In good weather, for passengers who don't mind a slow trip, they are suitable for longer distances as well.
