Shackles used for mooring or anchoring must be durable, strong and capable of being sold with a test certificate, in other words ‘fit for purpose’.
EYE Marine stock 17 types of shackle ONLY 9 of these are suitable for mooring, those that are unsuitable include Stainless and Commercial Shackles.
Generally, chandlers do not supply shackles suitable for mooring, you will no doubt be offered a bright zinc plated Commercial Shackle, the ill fitting pin will be the same size as the body, you will not be offered a ‘Test Certificate’.
Question – How do I tell if a shackle is suitable for mooring or anchoring?
Answer – If the pin has larger diameter than the body and a Test Certificate is available. These shackles are usually described as either to BS3032 (British Standard) or US Federal Specification. They are not expensive.
