i cut out the old and add tabs to cut out the new one accurately (cut out the old stuff with a Fein saw) (the post may need a hammer and chisel) (that area has a bit of thickened polyester that will be busted out)
fix the deck that is likely rotten around the chainplates. from the bottom if the deck is not broken
the gaps around the new bulkhead can be filled with thickened epoxy prior to taping in place
filet around except for chainplate area
tape in place both sides with 1708 dbl bias cloth 2 layers 7" and 5" (don't tape where the chainplate goes)
make sure your chainplates will be in the correct place. measure from front as they are often crooked/ should be equal from stem on both sides
look at the aft bulkhead too, replacing the seats as well makes the inside that is never used look nice (the seats are a bit structural)
