As requested, here are a couple of pictures of the stern anchor arrangement we use with the Ankarolina spool of woven rode. (Oops, I forgot to move the electric cord draped over it.)
On the outside is a horseshoe buoy rack that was handy to work into the mounting. You would have to devise your own way to mount it - there are several bolts around the perimeter that you could replace with longer ones to effect a mounting. I use those heavy duty reusable twist ties to secure it (orange one at the top).
