I bought mine from:
Griff Chains Ltd
Quarry Road
Dudley Wood
Dudley
DY2 0ED (Road Map)
West Midlands
Tel: 01384 569415
Fax: 01384 410580
www.griffchains.co.uk
* Director - Terry Wood
The website doesn't seem to work but the chain is good. I went to them because they were the only firm I could find who manufacture chain in the UK rather than import it. I would not buy chain from an unknown source but that's my choice, plenty of people buy chain from the local chandler or off eBay and are probably quite happy with it.
Another British chain supplier is Bradney Ltd. They don't manufacture any more but I was assured by their sales manager that the chain they import is quality-controlled to the same standard as that which they used to make.

Hi tomframe.
Price is one thing but I have been looking for some decent 8mm and the breaking figures are all over the place even frightening. In most cases they don’t even have ½ the breaking strain of 8mm Dyneema rope???
I have just used Twisterowners link and as usual the chain is priced but no spec at all.
I will give them a buzz tomorrow, could be interesting.
Can we ask Twisterowner, what size chain he bought and what was the breaking strain declared as?
All the best……..Peter

I bought 65 metres of 8mm chain calibrated to DIN something-or-other for use on a Lofrans Royal.
Afraid I have no record of the quoted breaking strain but a phone call to Griff should get you the figure. [If you do call them, please post the result here, it would be interesting to compare with others].

To turn it round a bit, has anyone actually experienced PROBLEMS with chain from particular suppliers?
I percieve that over the years some chain has been better galvanised than other, but it is very difficult to be truly objective on this, and certainly none has actually failed.
Did once place a 'next day delivery' order by email with GRIFF.....when nothing arrived after a week I phoned to be told by a puzzled woman "but of course everything is closed down for *the* fortnight". Well, I'm not from the Midlands..........

Not I, and I don't want to. That's why I buy what I hope is the best!

Will be off to Griff chains as I have just seen their prices. Thanks for the heads up.

And another thing.............
If you buy from Griff you can do as I did, and get them to fit an enlarged link at the end of the chain. This allows you to fit a decent sized anchor shackle.

Hi Twisterowner:
I called Griff today and spoke to a very pleasant lady who gave me the following on their 8mm chain.
Grifchain…. £4.41incVat…. Grade 30MS…. 3243kg (breaking load)
This is a list of others I had already typed in so could cut and paste…
Euro-Rope…… Foreign…. 2500kg
2007Marine---12vmarine….. Din766…. British made….. ???
Ukyachtrigriggingsupplies…... Dutch…. 2500kg
StainlesDirect…. Stainless Aisi 316….. 2680kg
MarineMegastore…. 2300kg
Quay West Marine…. Grade 30MS… ???
Marine megastore…. Lewmar calibrated... British…. 3243kg??
Plastimo…. 4030kg
I couldn’t get a price anywhere on the Italian Maggi which is supposed to have a 4000kg breaking limit
So in conclusion the Griff looks ok but not great at 3243kg and the surprise was Plastimo at 4030kg, while looking at the Megastore Lewmar chain it has a remarkable similarity to the Griff spec???
Either way it all proves nothing but I will probably shell my money out with Griff or maybe megastore if I can get a deal, but certainly not with the cheaper lot if for no other reason than peace of mind and to avoid poor old PickledPig plight of a dayglow chain locker…..
E&OE and all that lot.
Thanks again for your tip……….. Peter

Would have thought that this was sufficient? Can't imagine how you would go about breaking chain on a boat with this sort of load.

Hi, Pye_End.
What type of boat, with what sort of load, anchoring in what type of place and conditions would you consider that sufficient for and why?
Regards.. Peter

I am trying to think where I have seen estimated loads when anchoring. Certain others here will no doubt have them at their fingertips. It is certaily no where near these levels.
I would be surprised if the average yacht will get to 10% or even 5% of the strength of the chain. Imagine putting a 3t weight on your stemhead fitting - what's the chance that your stem head will still be there?
Chain is used really for its catenary (ie weight) and longevity (pretty resistant to chafe) although it has been said that UK leisure boats are more addicted to chain than many other countries.

Hi again Pye_End
I have no idea where your thoughts are coming from to suggest an average yacht couldn’t exert more than 5% of the (3243kg) that is about the weight of 2 normal 12 stone chaps…. On that calculation we could save a lot of dosh and just get garden chain and a mud weight.
2 years ago summertime in the Aegean I dropped the hook in the bay of an island in the Cyclades and sat out a force 9 + blow with my grandchildren on board, Glad I wasn’t using your anchoring thoughts there.
I have no idea what you sail or where, other than East coast, but it must be a little different to the East coast I know.
Anyway I wish you well and apologise to tomframe for drifting on his posting.

Without doing too much trawling this is in the anchorwatch website:
WIND FORCES
The main force which is experienced by a yacht at anchor comes from wind resistance. It is proportional to the wind speed squared and to the frontal area presented by the yacht. Broadly speaking the frontal area will be proportional to the square of the length. Experience with our own yacht MYFANWY (a Hustler 35) shows that the cable tension in a wind varies widely over time. But, provided snatching does not occur, the maximum force on the anchor cable is given by the approximate formula:
Maximum force in kg = (yacht length in metres)2 x (wind speed in knots)2/500
For me, at 8m, and say wind force of say 35knots I get 156.8Kg of force. From your Griff numbers this gives a load of 4.8% of total chain capacity.
Now to me this sounds reasonable - I have no windlass and can weigh anchor in a F5 with a bit of fetch. Wouldn't like to try much above that though. Doubt if I could haul 2 fully grow men. Have weiged anchor in a 7m in a full blown gale, but it did take 2 of us (no engine BTW).
Glad you got through your F9 ok - what do you reckon your peak load was on this occasion?

I wrote this up for YM, published late last year. All figures standardised on a boat of about 35 ft, wind speed 42 knots.
Theoretical loads vary from 402 to 818 kg.
Measured loads using Anchorwatch were 150kg and 170 kg although the boats were slightly smaller, 30 and 33 ft.

Your Myfanwy website is John Knox's. I exchanged lots of e-mails with him before writing up my YM piece. The 402 kg figure was calculated using his expression, which he tells me agrees very well with the measured forces using Anchorwatch. The 818 kg is from ABYC, and seems to incorporate many factors of safety. Even using that, it is a lot less than the measured 8 mm chain UTS of nearly 4000 kg. Of course, UTS should never be quoted in cases like this, a factor of four is a reasonable SWL, but that still leaves plenty.
