The term Zille (plural Zillen) is used for a family of flat-bottomed vessels which are used in the Danube River regions of Germany and Austria.
Boats with a wider aft area are also called "Plätte"; they fall under the general classification of "Zillen".
Production facilities for Zillen are mainly in the Upper Austrian Danube in the Engelhartszell area.
On the northern bank of the Danube there are two family businesses that have been building Zillen for several centuries.
The shipbuilders offer some fixed Zillen types, such as a Zille for firefighters, in standardized dimensions.
The proverbial robustness of Zillen offers good reason for the continued existence and use of this traditional watercraft.
