Shackle (unit of measure)
The unit of measurement shackle , also known as chain length , is used as a measure of length in shipping . Anchor chains consist of several parts that are connected to one another with capsize shackles . With each anchoring, the number of chain lengths used is adapted to the respective water depth and the nature of the anchorage ground.
The chain lengths, or shackles for short, were quite different internationally. These different values applied to a shackle:
- Germany 25 meters or 13.7 thread (Engl.)
- England 21.95 meters or 12.0 fathoms
- France 30 meters or 16.1 fathoms
- Italy 27.44 meters or 15 fathoms
- Austria 25 meters or 13.7 fathoms
