The port chainplate on my E-23 is attached to the plywood bulkhead. It has some delamination and clearly has lost strength. Is it necessary, from a structural point of view, that it be attached to the bulkhead? I can remove the old plywood attachment and replace with solid wood which would be far stronger and more decay resistant. I want to do this right because I love sailing this little beauty and I want to get to it fast so I don't miss too many races. Thanks
