10mm Anchor Chain for Quick anchor winch: DIN or ISO?

[element]

Hi,

I want to upgrade to a longer anchor chain for my 39i Performance (French Build)
I have seen a nice price for G40 grade chain.
However I have to choose for 10mm ISO or 10 MM DIN chain. 
Does anybody know what the Quick Winch takes better?

Thanks.

You don’t say which Quick windlass you have?

Our Quick Antares uses 10mm calibrated chain. We have 60m - should have gone for 100m.

I have the same Antares and 10mm 100m chain. Replaced it 2y ago. Had hard time find exact match and at last decided for calibrated ISO standard. Works perfectly. I’ll try to find my reciept to double check and will update if any different than from top of my head.
I went zinc way and not SS and put a mark in my calendar in 10y time to replace. Figured it’s still cheaper that way. But I’m in the marina with bow line and use my anchor only for about 45d per year.

The reason I changed was not because of age but rather necessity. I lost my anchor in 30m deep water during anchoring with storm approaching. Went on buoy with night approaching about 30nm away in F7-8. It wasn’t pleasant at all. Chain was 12y old at the time. But we were there in no time... 😉 (storm passed quickly so the sea wasn’t too bad)

All thanks for the remarks.
I have a Quick Antares winch. I measured the chain I have now on my boat. It is 10 mm DIN (28mm wide opening between a shackle, where ISO is 30mm), which seems (in Europe) to be the most common.

I think I will order 65 meter G40 chain.
I have currently 35 meters which is sufficiently for Dutch shallow waters with only 2 meters tidal difference. But this is not enough for the Channel Islands where tidal differs more than 10 meters at spring.

We are looking at changing out our 10mm G4 38m with 69m chain with a Quick Adelph 1000 windlass. Our Chandlery says the best way to tell between 28 and 30 degree chain is to just take the drum off the windlass and bring it in and they will run the chain and line over it. We are probably going to do that in the next few weeks and will let you know the results.

Hi All,

One has to consider the weight on the bow... 60 or 70m of chain is a lot of weight...

Cheers,

Agree that it is a lot of weight.

But I am slowly upgrading by boat for a Atlantic tour of 2 years where we will be most of the time lying behind our anchor. 
Under these circumstances I want to sleep well and fully rely on our anchor set up. Also when there is 40 knots of wind. Therefore I upgraded as well the anchor to a 25 kg Rocna.

So for me this assurance literally outweighs the extra weight of the chain.

Just a thought.

Two years ago I couldn’t understand why Affinity wasn’t sail very well close hauled - we just weren’t getting our usual performance and we were off the coast of Galicia. I went forward to find the anchor was full of water. We had been in the yard over the winter.

The anchor locker scuppers were blocked so sea water couldn’t flow through the locker. I now check the scuppers at the beginning of each season and when I fill the forward water tank. The water tank overflow discharges in to the anchor locker.

Thanks for the heads up. We have the Jeanneau only for a few months and have not sailed a lot in the Winter season. I was not aware that this could be an issue. Will check regularly next season.

I owe some explanation about standard used for my new chain.
I have now 100m 10mm DIN 766 chain (10x28) but my previous chain was 10x30 ISO 4565. Must say, chain is going through gipsy like a dream, possibly even better than before (but that is just personal feel not a fact)
It seems that this diameter of chain is suitable in both standars for Antares windlass. Never had any problems with eider.
Just in case somebody will ask the same question in the future.
