Hello Dean, Not sure you need to add an additional backing plate unless you are putting the winch somewhere that there wasn't one before. There is a thick solid plywood core where the primary winches are mounted on my 1981 C and they don't put a backing plate under it in the factory. I replaced the primary winches in 2020. I did use fender washers on the winch bolts to spread out the load. How you repair the previous holes might play a role in choosing to put a piece of G10 under and of course adding a backing plate isn't going to hurt anything. I did go a little beyond just filling the holes - I started filling the holes by 1 drilling the hole out a little bigger in order to create a clean surface to bond to. 2 Grinding a tapered area into the glass at the top to enable me to lay in a piece of glass fabric on top 3 with masking tape covering the bottom of the hole, put in a little unthickened epoxy to coat the outside of the hole followed by thickened epoxy using microfibers or similar. 4 follow with several layers of glass and epoxy at the top once it cures, sand flush and use filler if needed to fill any remaining low spots before painting. This might be overkill but gave me confidence that I was restoring the skin strength.

Don’t use plywood. Aluminum or G10.

I'm about to finally replace my old 2 speed Barient 25 primary winches on my C 34, with Harken 46 Self tailing winches. Anyone have experience doing a similar swap? I fully expect I’ll need to fill old holes and drill new ones. And probably glass in aluminum or plywood backing plates. Any other hints and tips?
