Jimmy Green Marine Recommendations:

  1. Select component parts of an anchor rode or anchoring system with comparable break loads
  2. Select hot dipped galvanised or marine grade stainless steel shackles for anchoring applications. Galvanised are less expensive and avoid any issue with dissimilar metals when connecting galvanised chain and anchors: Stainless Steel in contact with Galvanised Steel
  3. Select rated shackles for anchoring – check the load rating for compatibility with the chain and rope
  4. Avoid commercial pattern non rated shackles for anchoring – if there is no provenance regarding their origin, there is no way of telling how weak they may be.

Jimmy Green Marine stock anchoring shackles with a guaranteed manufacturer break load – test certificates are available for added reassurance – file them in the ship’s papers for future reference.

Shackles can be used to join an anchor warp to an anchor chain and to connect the end link of an anchor chain to the anchor.

Parts of a Shackle

Anchor Connections

Anchoring shackles can be used to attach the anchor to the end of the chain – two shackles back to back is the tried and trusted method.

Back to Back refers to the crown of each shackle bearing against one another which results in both the pins taking the load correctly, one in the hole/slot on the anchor shank, the other in the end link of the chain.

Back to back shackles deliver excellent articulation which can be extremely beneficial for lateral anchoring loads.

Some anchor connectors still require the fitting of an anchor shackle to facilitate articulation
