Title: Raft Authors: Venue: Wikipedia Year: unknown Canonical: wiki:raft URL: https://en.wikipedia.org/wiki/Raft Collector: wikipedia OA: true ABSTRACT 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 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.
