Historic Zeesenboats

The brown sails of the Zeesboote on the Bodden are typical for the region. In the past, the boats made of oak were used by fishermen on the bay because they only have a comparatively shallow draft and are therefore perfectly adapted to the conditions of the lagoon waters. With them they "zeeste", i.e. set the sails against the wind and sailed across the wind, pulling a large net behind them. The name of the boats is derived from the name of this fishing technique. Each fisherman had his very own boat, which not only adapted to the respective fishing grounds, but also to the individual needs of the owner.

A Zeesenboot, in Low German "Zeesboot" formerly also "Zeesenerkahn", is an up to 12 meter long, dimensionally stable sword boat from the time of sail fishing. The name derives from the fishing gear used, the Zeese.
