Awesome, appreciate all of the advice!

I’m slowly replacing all the chain-plates and will eventually do the standing rigging. There’s a great marine parts store around here that carries the Schaefer chain-plates. I’m replacing them one at a time so I don’t have to pull the mast and didn’t want to send off a plate for a template one at a time. The new plates seems a bit beefier. I changed all the bolts to 2 1/2″ long / 1/2″ diameter, added a lock washer to each bolt, and used 316 grade fasteners.

I was surprised how rotten the core was around some of the chain-plate ports and lifeline stanchions. I used a Fein tool to cut out the squares of the life-line stanchions through the deck. I re-bedded using thickened epoxy and backed with two layers of 24oz roven-woving. The original flat-head screws didn’t allow for enough torque to get the nuts off the stanchion bolts!

I also noticed the old plates had an odd bend near the pin — not sure what would have caused them to be out of true.

If you’re in the mood for this project — these are the chain- plates from Schaefer. The marine parts store should be able to get them at half of the listed price. https://hardware.schaefermarine.com/index.php?main_page=product_info&cPath=147_125&products_id=3556
