Rinse it as well as you can when you can and use something like a bristle brush to get mud and critters off.
On a calm day, lay all the chain out flaked flat on the deck
. Let the anchor locker
or well air out, and maybe give it a wipe down.
Be wary of using metal mixes, like galvanised chain and SS shackles. It's more an issue in the anchorage of a marina with stray current
, of course, but my understanding is that it's worst in brackish water
, like Florida's or the Chesapeake.
End for end is a good idea, too. Inspect for corroded or "stretched" links before their time. Consider going to a better grade if you know you're sized properly.
Use a snubber at the waterline and/or a bridle
from the bow cleats/bollards. If you can cushion the shock loading of the bow yanking up the catenary, it will improve your ride at anchor
and make the chain last longer.
