Bolts that secure bulkhead to deck, missing backing

A fellow member (Peter, www.mostlyaboutboats.ca) of the balladexchange forum (http://balladklubben.se/balladexchange) commented that I should check the backing of the three bolts that secure the large bulkhead to the deck. In his boat Albin Marina had placed the backing (plywood) too far forward and there was no backing to support the bolts. I checked and my boat had the same issue. If you look at the drawings the backing is clearly supposed to be there (link).

I used a 40 mm hole saw to cut out three sections of fiberglass and then used the same hole saw to cut three pieces of Okoume plywood. I used the hole from the hole saw to line up the pieces of plywood and then applied generous amount of WEST System's Six10. The next day I sanded the area and painted it.
