Bundstaken
A Bundstaken , also Schurbaum (Dutch: schoorboom) or Schricke , was used in inland navigation for boots to keep the ship on course.
construction
The Bundstaken consists of a roughly worked tree trunk up to five meters long with a diameter of up to 30 centimeters. At the upper end are the horns , formerly made of wood, later also made of metal in a T-shape. They serve as handles for handling and for attaching a line. The lower end of the pole is reinforced with a steel point of different shapes. The shape depends on the expected river bed or embankment. Spread, fork-like tips were used for very soft ground. This is also known as the claw.
handling
The Bundstaken was set diagonally in the ground during the unpowered journey and when approaching the bank in the direction of travel and fixed with a line at the upper end in the bow area of the ship, mostly between the double bollards. So the bow could be steered back from the bank into the fairway. In the Oder region , this process was called zipping . Another use is the use as a spacer when mooring a ship on a sloping, unpaved embankment. The bund stakes prevent the ship from touching down on the embankment.
