I searched for Duplex stainless chain without any luck. The one place that was suggested to have it wrote me back saying it is not available.
The AISA 316 looks interesting though.

Dear Mr. Lessnau,

thank you for your inquiry.
We don’t have the duplex chain in our product range, because the demand is not high enough.
We could only offer AISI 316 or AISI 316Ti and only to companies because we are dealing as a distributor.
Thank you for your understanding.

Best regards

Hallo
the problem is that nobody wants to produce it since the order are to small , we have found a German manufacturer that produces it for us since we order 1000 meters each order.
The chain is costly but the best on the market.
I can advise anybody that want a strong anchor chain and wants to save weight to go this route, 1.4 kilo per meter with a strength of 6400 kilo is the best on the market.

Asai 316 has a strength of 4000 kilo or 50 % less

Greetings
Gideon

Whats the ideal weightdistribution on a fast cruisingcat. Between bow and stern? Depends on hulldesign but in general?
I guess 40% bow and 60% stern?

Designers think in different terms - the LCB-longtitudinal center of buoyancy- is typically a bit aft of amidships, at say 56% aft of the start of the waterline, and the weights must balance around that center, with closer in being better because it leads to less pitching.
