ACCO chain rusting

The kind who doesn't own the $1.5M boat, hires on by the day and who rarely has a need to anchor.

dock cart trick works like a charm right up to the point where the next 50 feet of chain collapses the whimsy cart. Then you go get the work float and do it right without ticking off your neighbors or marina for crushing the common buggy. Thank you.

It's time to ask your marina to get real dock carts if they can't handle 282 lbs. Taylor Made are rated for 300 lbs.https://www.westmarine.com/buy/tayl...Nq268Hzl1LzuzSbdy8tKW0LJkhFasEcBoColcQAvD_BwE

Look, I can appreciate the art of condescension as much as anyone. But my 250 feet of 1/2" HT chain might weigh a hair more than you're suggesting, and I'd be a bit ticked off if I showed up at a marina and needed to use the cart only to find it broken in a heap because the old sailor is lazy and entitled.

Not condescension, just good natured sarcasm. But in all seriousness I'd be real careful about putting 300 lbs plus my 190 on the 4x8 marina work floats made of plywood over foam I've been on. Water up here is a bit chilly for a dip. Those are designed for waxing boats, doing fiberglass repairs or working under the docks. I'd be more inclined to split my load between 2 dock carts if need be than use the float. Now if your marina happens to have camels like we used for cleaning oil spills (about 20 x 8 made out of 6 x 6's ) I'd be more inclined.
Btw, I just checked and the fold up dock carts are rated for 350 lbs. Granted in many marinas they're only used for carrying groceries and the owner's luggage, but actual boatyards use the same carts for real work.
Btw your chain would be 600 lbs. Definitely 2 carts or something more serious like your bow over the bed of your pickup.

Yeah, agree: I bought 215’ ACCOR 5/16” chain for my sailboat and anchored hundreds of times over 12 years in the Bahamas and Florida, the chain was good, but I always left it on deck with fresh water rinses or plain rain until I got to Home Base, then it was a real rinse with the garden house, then dry and back in the chain locker.
Turned it only once in 12 years.
The next owners did none of that and when they came last year to rent my dock, the chain was all rust and the boat was another POS old sailboat.

From the pics you showed I see rust on all surfaces, but whether it's scraping on the chain guide, the sandy bottom or itself in the anchor locker isn't my real question. Quite frankly none of those should cause this. What is the white I see?

And made in CHINA most likely.

Donate the old chain to one of those local fishing wrecks.

Are you certain? See:

FWIW, a chain can be re-galvanized.
Had one done once, and the results were not desirable. When they did it, they gathered up a number of loops with heavy solid wire and hung the bunches from the dip hooks. Some areas were galvanized together and had to be broken apart, leaving exposed steel again. There were also drip-like elements on the chain that would cut up your hands when flaking the chain until the gloves were found. Then, when running the chain out or retrieving it, there were a lot of little zinc bits that broke off and really made a mess on the deck.

Made in us with another countries steel wire is what I'm thinking. The quality of steel and ss has certainly gone down over the years. I have some very heavy duty carts if you need remove and replace your chain. Your in s fl?
