Deck Overhaul { Need Help}

[Blu_Lunch]

Got in there today it's tropical here, removed half the foam and it came out easy, found more damage the entire center stringer is gone and need to replace 3 feet on the port side stringer and the same where the tray goes for running cables and the rear bulk head bottom 2 inches is marginal. Need advise on wood for the stringers, the center 110x9.5x1 can I use 2 pieces of marine plywood glued or resin and encapsulated in 9oz cloth and resin. And the bulk head I hate to tear it out it only has a very small amount of damage can I just add to it. Something interesting the center stringer at the bow end is attached to a bulkhead only and the bulkhead is not attached to anything and never was, no sign of it ever being glassed. I plan on encapsulating all the new wood, the glass the new stringer with 24 oz mat a single layer. That's what Wellcraft did with the bare wood.
