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.

Lachter
The lachter (also Berglachter) was a common unit of length used in the mining industry in Europe, usually to measure depth, tunnel driving and the size of mining fields; it was also used for contract work. In most German-speaking mining fields it was the most important unit of length.
