After Bennett sacrificed his anchor to the tree root gods of Lake Lanier, I decided that I would add a new anchor swivel to my pre-emptive maintenance. Bennetts’ swivel sheared at the bolt that holds the 2 halves together, and I have the same standard 20 year old swivel that spent its life in and out of salt water. The recommendation was for a Mantus Swivel. I ordered the S1, for 1/4” to 5/16” chain. I think $75 delivered.
