Me Too
I had exactly the same problem with my O'Day 222 after it was stored for a few years whilst overseas. I had some custom chainplates made, about twice the length and width of the two pathetic originals. In addition, I used some stainless steel washers, as large as woould fit to provide extra backing against the deck - that increased the surface area about 4x. To ensure there was no cor rot around the deck hardware, I made a few small holes and injected the core with penetrating resin. For the bulhead, I just cut out anything that looked rotted, filles again with penetrating resin, surface with plastic wood for cosmetics, then resined the new chainplates into place. What a job - doesn't look as good as new but probably alot stronger. I'. waiting for some wind this summer (it's on a lake) to really test out. I'd try this rather than removing the entire bulkhead.There are some other suggestions in the archives under "chainplates" that look like they may work as well.Good luck !Jim
