De Snip is what the Dutch describe as a Grondzeiler. It is a two storey smock mill on a single storey base. There is no stage, the sails reaching almost to ground level. The mill is winded by tailpole and winch. The smock and cap are thatched. The sails are Common sails. They have a span of 15.30 metres (50 ft 2 in). The sails are carried on a cast iron windshaft, which was cast by Fabrikaat Sallandia, Zwolle, Overijssel. The windshaft carries the brake wheel which has 54 cogs. This drives the wallower (25 cogs) at the top of the upright shaft. At the bottom of the upright shaft there are two crown wheels The upper crown wheel, which has 30 cogs drives an Archimedes' screw via a crown wheel. The lower crown wheel, which has 29 cogs is carried on the axle of an Archimedes' screw, which is used to drain the polder. The axle of the screw is 34 centimetres (13 in) diameter and 4.07 metres (13 ft 4 in) long. The screw is 99 centimetres (3 ft 3 in) diameter. It is inclined at 27°.
