Before putting in the water, I wanted to re-bed my chain plates. Had some rot in the port forward bulkhead and center bulk head. Fortunately they weren't bad...only an area of 4 - 5 inches wide and 6 inches deep. I dug out all the bad wood, vacuumed, made patterns and cut new 1/4 in. marine ply laminates. Used West System Epoxy (regular mix and thickened with structural filler), and put it all in. Also follow Don Casey's (Good Old Boat) idea of cleaning out saturated deck core around slot the chain plates go through and filled the perimeter with thickened epoxy (there was a good article about this in Good Old Boat magazine not long ago). What a job this was. Glad to get it done. Would have taken pictures but don't have camera. Thanks to all who posted pictures of their similar bulkhead repairs because it helped a lot.
Main reason for writing this is thinking why owners don't inspect these things more often. On the 9.2 A, it is a simple matter of securing two opposite standing rigs, taking deck plate off, unbolting the chainplate, removing and rebedding, and reversing procedure to re-install. I'm guessing (from what I'm reading) just about every S2 and a lot of other boats have leaking chainplates, hence deck core damage and bulkhead damage. So.... catch it early, rebed so you don't have bulkhead damage, it would be soooo.... much easier.
