Capt'n Pauley's Virtual Board Yard has shown us how he backed up his chain plate. This is in a similar vein to the backing up I did on Solace for my forstay installation. In my case the forstay padeye had no support at the deck and so I installed a small bulkhead in the chain locker and put two stays from the padeye down to the bulkhead. You can read about that here. For Capt'n Pauley's article, read on.....
The aft chain plates on my Columbia 10.7 had a problem; the tabbing on the hanging locker had broken, allowing the shroud to poll up the chain plate and crack the deck. That allowed water to leak into the deck core, weakening it.
The aft chain plates on my Columbia 10.7 had a problem; the tabbing on the hanging locker had broken, allowing the shroud to poll up the chain plate and crack the deck. That allowed water to leak into the deck core, weakening it.
Before I could re-core the deck, I had to off-load the chain plate and hanging locker. I accomplished this by yying the bottom of the chain plate ( a stock Schaefer part) to the lower srtinger by means of a cable and turnbuckle. The following photos show how I did it. 
I used a 24" length of 1-1.2" x 1-1/2" sainless steel angle underneath the stringer. The forged eye bolt passed through this angle. I also filled in either side of the eyebolt with wooden filler blocks, then laminated 6 layers of fiberglass cloth and epoxy. The fiberglass strips went down the hull, scross the top of the stringer and then down the wood blocks and hull underneath the stringer.

The new chain plate in place. This chain plate extends below the locker to connect to the cable stay.

The finished installation. A very minor cut will need to be made to the edge of the berth cushion.
