8mm DIN766 AQUA4 Grade 40 Calibrated Hot Dip Galvanised Anchor Chain, manufactured by Maggi Catena in Italy, every link is tested to the proof load during production
8mm AQUA4 DIN766 is generally suitable for yachts up to approximately 12 metres, length overall
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

Sample test certificate
There is one main calibration for 8mm chain - DIN766
N.B. Some Windlass and Chain manufacturers also refer to 8mm ISO 4565 but the dimensions are exactly the same as 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:

1Kn Force = 101.972Kg Break Load
40.2Kn = approximately 4099kg
Maximum Pin Diameter refers to the largest pin which will fit comfortably in the end link of 8mm DIN766 chain
