8mm AQUA7 DIN766 has a break load similar to 10mm Grade 40 chain
An 8mm AQUA7 anchor rode can therefore be approximately 50% longer than the 10mm AQUA4 equivalent without any increase in weight.
8mm AQUA7 is a long length, high strength ocean cruising solution for yacts up to 12 metres, length overall
10mm Grade 40 chain is generally suitable for yachts up to 16 metres, length overall but please ensure that you take account of all the relevant information in determining whether 8mm AQUA7 will be suitable for yachts between 12 metres and 16 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
The strength of 8mm AQUA7 means that it is best considered as an all chain solution rather than a chain/rope combination.
14mm is the most compatible diameter rope to splice into 8mm DIN766 chain
16mm diameter rope can be spliced into 8mm DIN766 chain but is a tight squeeze
A minimum 18mm diameter nylon rope would be required in order for the chain and rope combination to be reasonably compatible in terms of strength

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:

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
8mm AQUA7 DIN766 pitch tolerance is Plus or Minus 1.0mm
