Re: looking for a chain scrubbing brush
While cruising the Caribbean, I created a chain scrubber that I think works well. Using a 12" piece of 4" PVC pipe, split lengthwise. A piece of rubber sheeting as a hinge on one side, bolts protruding on the other side with a piece of shock cord for closing the opening side. Inside, I attached four small kitchen scrub brushes. An 8 lb dive weight is hung from bottom side by a rope that is attached to scrubber and extends upward for a bout 15 ft. The devise is opened and then closed over the chain, the line is ties to the bow rail and the scrubber is lowered into the water over the chain, submerged by several feet. As you raise the anchor the scrubber cleans the chain and it is flushed by the see for the several feet it is submerged. It removes most of the soft group and mud that accumulates with longer anchoring times. This works well for 3/8" chain, modifications would be needed for other chain sizes.
