The paaltjasker Meesterveen formerly stood at Amen where it was erected before 1940. It was discovered in the 1980s in a farmer's shed. It was erected at Zeijen in 1983 as part of a project for the unemployed. The tjasker is owned by the Molenstichting Drenthe.[9] The four Common sails have a span of 5.50 metres (18 ft 1 in) and are carried in a wooden windshaft. The tjasker is listed as a Rijksmonument, number 413729.[10] Photographs taken in early 2009 show that the sails have been removed.[11]
