Newbie move. Second time docking and swung stern wide and clipped neighboring boat's anchor on the stern bench. The port side bench mounting tore out (of the soft wood) and upholstery was torn

Is it even reasonable to find a replacement bench for this vintage? Any suggestions for repair/replace? Are there specialty marine furniture shops? I am in Chicago.

I'm reasonably handy and based on the damage, I think I could do the following for the structure of the bench:
* remove as much rotted wood on the arm mounting points
* add wood hardener (epoxy) to the remaining exposed wood in the arm
* mount a suitable size piece of marine plywood to replace the fixed with through dowels and additional epoxy
* drill horizontal holes in the mounting points
* add prong nuts
* seal up the added plywood (more hardener??)
* re-staple upholstery

It's more important to me that the structure of the bench is solid. The damaged upholstery could be patched over for now.
