In 1969 an interesting and unique shipwreck was found at lot U 34 in the polder of eastern Flevoland, the Netherlands. The ship, dated about AD 1530, was 30 m long and completely clinker-built. The overlapping strakes were connected by a combination of rove and rivet and small treenails. In the Netherlands a few similar clinker-built shipwrecks have been found dating from the same period, but not as large as the ship at lot U 34.
Fish and fortune for Holland. The ‘waterschip’, floating fishpond and tug boat and the prosperity of Holland in the sixteenth and seventeenth century. In the province of Flevoland forty wrecks of ‘waterschepen’ have been found, of which twenty have been excavated and only two have been published. These fishing vessels date between 1500 and 1700 and played an important role in feeding the fast growing population of the urban centres in Holland. The ships form an interesting group of vessels because they have been in use over a long time-period, serving different functions (fish transport, fishing vessel and tug-boat). According to historical sources they span an even longer time-frame: from the fourteenth to the nineteenth century.
