While stuck here in St. Lucia at the dock I'm doing a number of boat projects that I've been postponing, and a couple of days ago I decided to take my chain out completely and clean the rust off it and turn it end-for-end again. I haven't used more than 100 feet since the boat was recommissioned after getting damaged in hurricane Irma and even before that I'd had some bad rust. I got special G70 chain, but sourced it badly and didn't get the quality I wanted, so as soon as the galvanization was abraded by the bottom sand it started to rust. Most of the chain is good, but there are links and small sections which were at the bottom of the chain locker and got very corroded. And there was a solid rust ball at the end of the chain that even 24 hours of soaking in hydrochloric acid didn't quite loosen!
My original plan was to head to the Pacific and deep anchorages, so I originally got a lot of chain (over 150m - almost 500'). But now I think I'll probably be in the Caribbean for the life of my replacement chain, so I've been thinking about minimizing cost (and weight) for a full-chain replacement.
I can get a full drum of chain (10mm / 3/8") of 360' which is what I'm thinking of getting, I've anchored in 50-60' many times and used 300 feet or so. But usually I'm in much shallower water.
