The Port chain plate on E23's are fastened to a wood ply bulkhead. The Starboard one is bolted to a thick fiberglass protrusion and appears much more substantial than the Port one. I have been worried about this for some time and now that I have shoveled the snow off the deck and gotten back inside the cabin, my port bulkhead, around the chainplate bolts is discolored from moisture. I have tried the sharp screwdriver test and cannot push it any farther into the discolored areas than I can into the other areas of the wood. I plan on rebedding the chain plates where they go thru the deck, but should I be freaking out about the bulkhead and looking into replacing it. It does not appear to be delaminating or rotting at all, but I'm not sure how long the water has been getting through to it, or if it has been weakened in any way. Any advice or wisdom out there? Thanks
