I fish primarily out of Savannah, Georgia. At certain times of the year, currents can get pretty strong, which requires heavier anchors, as well as anchor chains. Through the years, I have tried galvanized and painted anchor chains, but nothing seems to stop the rust or protect the boat when you are pulling anchor. The solution isn’t anything fancy, however, and it’s quite effective. I cut a tube used for a bicycle tire so I have one long, continuous tube instead of a circle, then simply slide it over the chain all the way down to the top of the anchor shaft. Now your boat will remain rust- and nick-free when pulling your anchor in.
