Chain is 5/16 not 3/8. I got rid of the swivel. Had to use the cheap shackle for now to hang the anchor but looking for a good one again locally.

The potential problem with this type of swivel is that it will only pivot in one direction on the anchor shank. Which means that if the boat gets off to the side of the anchor the swivel cannot pivot to line up with the rode and thus the direction of pull. So a side (shearing) load is put on the swivel pin itself, which is intended for a load straight through it, not a load trying to bend it off to the side.

The proper way to attach any swivel to an anchor shank is with a shacke with the closed end of the shackle through the shank and the pin through an end of the swivel. This allows the swivel to pivot in any direction and line up with the load.

Unless one has an alignment problem with their anchor to their pulpit when the anchor is retrieved I believe a swivel adds one more potential failure mode to something you don't want to have fail. Ever. After reading Earl Hinz's book about mooring and anchoring in which he graphically describes the difference between attaching a swivel correctly and incorrectly and the potential consequences of the latter we removed our swivel from our all-chain rode and threw it away. It had served no real purpose when it was there and we never missed it when it was gone.
