There are many earlier model PDQ 36's that have had to rebed their baby stay chainplate. If you do a search for "baby stay" you'll receive many returns from the PDQ 36 Forum on the subject. Hopefully this will help a little.

Be sure to inspect the bulkhead between berths. I lost my first boat, I believe, due to this problem not being addressed by POs and then covered up with a poor repair.
