Oh no, another outbreak of anchor-confabuloritis (anchor-myxomatosis in Ozzie 
) is about to strike this thread down :ambivalence:

Is 10mm chain really 10mm?

I read the first part of the article on the Amel site and thought "This guy knows his stuff" so I quoted the first part of the article not realizing it was your work!
I'm always interested in your posts. Thanks

Surely not! I think we've absolutely thrashed that one to death!
I think I'll log off (just in case) and go and watch the British Grand Prix.

I did not look at the Amel site. nor should anyone need to look at the site. If it was obvious on the Amel site that the quote was not theirs it would be a common courtesy to quote the original source, especially as that source is a member here. There may be no obligation to define whose original work is being quoted - but call me old fashioned - I think it is simply polite.
Coopec - if you feel upset - Others may have the same values I have, I certainly hope so - but I accept this may not be the case and in which case I stand corrected - and accept any admonishment.

Thanks, no problem. I am interested to know how you found the link, I can find nothing other than yours. I wanted to tell them their link is out of date but seems I need tp register before I can even send them an email.

If you buy the correct sized chain then most chain should be strong enough but galvanising (quality, thickness and adhesion) determines the life of the chain and as Vyv's website has entered central stage he has a simple cheap test to determine the adhesion of the coating to the base steel (a bent link test). The test does not determine gal thickness but poor adhesion might indicate a lack of attention to detail.

Not if it is American 3/8ths chain which is actually oversized as I explained above. My boat came with an ISO 10mm gypsy, but the chain had over length links and I eventually discovered that it was actually American 3/8ths chain. In Turkey 10mm ISO chain costs more than half as much again as 10mm DIN chain, and no local supplier had a long enough length of ISO chain in stock so I bought DIN chain and had a DIN gypsy machined locally at a fraction of the cost of a genuine Lofrans one.

You can't trust Europeans, British or otherwise, with sizes. In France plaster boards are 2240x1220... hang on a minute, that's eight by four... 500 grammes is a 'livre' (pound) to shopkeepers while builders often refer to 'puces' (inches). Meanwhile, don't let's get started on tons. 1000 kilos (France)? 2000 pounds (USA)? 2240 pounds (sometimes in the UK, other times we're back to the kilos). You know we're obsessed with the number 2240, of course.In Australia we have to accept either measurement.

I am always confused regarding UK measurements: I'll have to do some more research. I think you guys had to convert to metric when you joined the European Union but apart from that I become confused.........
Even 50 years later, many Britons still refuse to move entirely to metric. Distances are still measured in miles, yards and inches, weight in pounds and stones, even pints and gallons are still used. The US isn't pressured by the same trading problems as the UK, license however.May 19, 2017 (zmescience. com)
OMG!! It's not surprising I am confused....................

To reiterate again and building on Norman's and Gunfleet's posts:
3/8th" or any imperial chain come in a number of link sizes, BBB, G30, G43 and G70. G43 and G70 are similar (but still different). some gypsies are more forgiving than others and will accept different imperial standards, others will not and Australian metric G30 is a, totally, different size to European G30 - in fact more like 'some' imperial size.
As Gunfleet said 'You can't trust Europeans, British or otherwise, with sizes.' and that includes casually looking at Australian Grade L 'metric'.
The only way to be sure - take the gypsy off, usually pretty easy, and size the chain in the chandler, or buy a short length of chain and take it to the gypsy.
It is a very expensive exercise to get it wrong.
Galvanizing quality pales into insignifcance with these stumbling blocks

Sorry I didn't get back to you earlier
I don't know how I found the site originally but I just did a search on "Anchor chain sizes metric imperial" and got the link again.
Now for contacting them.......? After a lot of messing around I went to Yahoo Groups and found an Amelowners site but it is all in French.
https://fr.groups.yahoo.com/neo/groups/amel-owners/info
There are a few email addresses there.
Hope this helps
Cheers
