A Fluttermühle (Dutch: tjasker) is a type of small drainage windmill used in the Netherlands and Germany.
The boktjasker of Bedekaspel is located near the drainage smock mill Agnes.
The system of ditches do not form a complete circle so the mill can only operate with southerly to westerly winds.
The photo in the database of the Deutsche Gesellschaft für Mühlenkunde und Mühlenerhaltung (DGM) shows it having a complete circular ditch system for winding, [7] however recently dated photos show it in a static position taking water directly from a lake.
The paaltjasker is located between Weenermoor and Sankt Georgiwold and was built by millwright Richard Kluin from Ihrhove in 2000.
