Barge (Wikipedia)
Barge often refers to a flat-bottomed inland waterway vessel which does not have its own means of mechanical propulsion. The first modern barges were pulled by tugs, but on inland waterways, most are pushed by pusher boats, or other vessels. The term barge has a rich history, and therefore there are many other types of barges.Boat (Wikipedia)

A ferry is a watercraft that carries passengers, and sometimes vehicles and cargo, across a body of water. A small passenger ferry with many stops, such as in Venice, Italy, is sometimes called a water taxi or water bus.Ship (Wikipedia)
A ship is a large vessel that travels the world’s oceans and other navigable waterways, carrying cargo or passengers, or in support of specialized missions, such as defense, research and fishing. Ships are generally distinguished from boats, based on size, shape, load capacity and purpose. Ships have supported exploration, trade, warfare, migration, colonization, and science. Ship transport is responsible for the largest portion of world commerce.- A watercraft or waterborne vessel is any vehicle designed for travel across or through water bodies, such as a boat, ship, hovercraft, submersible or submarine.
