6mm DIN766 Grade 40 Anchor Chain is generally suitable for yachts up to approximately 6 metres, length overall

Factor in:
Displacement: Length ratio
Your cruising intentions
The anticipated anchorage conditions e.g. depth, seabed holding characteristics, the length of fetch and degree of exposure to prevailing winds
The length of chain that will be deployed and any extra scope provided by an anchor warp
The weight and design of anchor

Your anchor rode is only as strong as the weakest link so ensure that all your connectors and shackles are rated to the requisite break load

There is one main calibration for 6mm chain - DIN766
It is very important to check the size and calibration of your gypsy/chain before you order
If you are unsure we can help you to decide - we will take all reasonable steps to ensure you get the correct chain
The simplest way to check that you are buying the correct calibration is to take a measurement from your existing chain, providing of course that it fits correctly.

We measure 10 links because, in practice, it is difficult to measure one link accurately enough.
The links should be laid out flat and pulled tight.
Measure from the outside edge to outside edge.
Compare your measurement with our stock:
Jimmy Green Lofrans 6mm DIN766 = approximately 190mm

N.B. The measurement for an old chain may be a little longer than new due to a degree of wear and elongation in use

Maximum Pin Diameter = 6mm = the largest pin which will fit comfortably in the end link of 6mm DIN766 chain

Select the largest possible galvanised shackle or anchor connector by pin diameter to fit the chain.

Jimmy Green Quality Control and Accountability
Every length of chain is checked and labelled with the manufacturer, the date received and a corresponding batch number when it arrives.
The batch number is then recorded at the point of sale.
Every chain order is therefore traceable and accountable to the manufacturer Test Certificate
