Chainplate hole damage to bulkhead
I am in the process of doing the same repair to my 1983 25' O'Day. Your problem is not the bulkhead alone. I bet you have a lot of damage to the core material, which is just under the deck. I own my boat for 14 years, and the chainplate hole has been leaking for a number of years. It actually rotted out the bulkhead and the adjoining head sink area. Through the help of a great fiberglass company in Florida, I did all the repair myself for less that $210. My local shop wanted $2800 for the job. I bought a 1/2" sheet of marine plywood, teak finished on both sides from Jaeger Lumber 800 12th Avenue, Belmar, NJ and a boxfull of fiberglass and epoxy supplies from Fiberglass Coating Company in Florida. 1-800-272-7890 ask for Jonathan. Jaeger Lumber ask for Neal Slattery.If you need step-by-step description of the repair write to me at armenkh@aol.comPS. I found other areas of rot on my deck that I've been fixing since.
