A new kind of cargo for an old tjalk

De Verwisseling was built as a cargo ship in 1924 at the Wolthuis shipyard in Sappemeer, Groningen. The owner, with his wife and children, lived in the deck house, and in the cargo area he transported sugar beets, sand and potatoes. The ship proved to be a sturdy one, able to hold her course, low on the water and steady over both bows.

Passenger ship

In 1976 de Verwisseling was converted to a passenger ship, able to hold up to 20 people. The former cargo area is now a cosy guest residence with a ktichen, toilet, washroom with shower and three sleeping areas for up to 14 people.

De Verwisseling is a tjalk, a name that first appeared in the 17th century. A tjalk is built long, narrow and shallow, like a rounded shoebox. It has a full rounded bow and round edges. Most tjalks have one mast and are gaffel-rigged. Because the Dutch ships often had to traverse shallow waters, they were built without keel, opting instead for leeboards.


Rounded bow

Because of the wide variation in appearance, origin and usage, tjalks can be subdivided into several groups. De Verwisseling is a ‘boltjalk’, a steel tjalk with a rounded bow. This type of tjalk was mainly used in the area around Groningen.

‘Brown fleet’ or traditional charter?

‘Brown fleet’ is the term given to the professional passenger ships in the Netherlands, also known as traditional charters. This name references the brown sails with which these ships used to sail. The color was due to a coating given to the sails by a yellow-brown liquid, made with oak bark, which protected and conserved the sails.
