thumb|Traditional raft, from the 1884 edition of Adventures of Huckleberry Finn A raft is any flat structure for support or transportation over water. It is usually of basic design, characterized by the absence of a hull. Rafts are usually kept afloat by using any combination of buoyant materials such as wood, sealed barrels, or inflated air chambers (such as pontoons), and are typically not propelled by an engine. Rafts are an ancient mode of transport; naturally occurring rafts such as entwined vegetation and pieces of wood have been used to traverse water since the dawn of humanity.
A raft is a flat, simple structure made from buoyant materials like wood or sealed barrels that people use to float and travel across water. Rafts have been one of humanity's oldest forms of transportation, with people using naturally occurring floating materials to cross water since ancient times.
