The smock is thatched and the cap covered in vertical boards. The mill is winded by tailpole and winch. The sails are Common sails. They have a span of . The sails are carried on a wood and steel windshaft made by J H Westra  of Franeker. The windshaft also carries the brake wheel, which has 38 cogs.

At the bottom of the upright shaft, the crown wheel, which has 33 cogs drives a gearwheel with 29 cogs on the axle of the wooden Archimedes' screw. The axle of the screw is  diameter and the screw is  diameter and  long. The screw is inclined at 24.6°.
