Has anyone rebuilt the forward / lower chainplate area on an O'Day 28 (mine is a 1985)? If yes, what mechanism spreads the chainplate load to the deck? I.E. how is this chainplate actually connected in the deck? A sketch or photo would be wonderful. I have had some slight leakage of water into the port side and plan to go a bit deeper into the core but would like to understand what I'm up against. The connection is still quite sound but it is something on my future todo list. This will be my 21st season with this boat and it has been absolutely terrific!
