That bow support wood has been replaced already and with plywood maybe? You have to remove the end caps rub rail to get at the 5/32nds blind rivets that secure the bow deck aluminum.
This is what it should look like for factory bow deck support in the older SC boats like my Chief but I don't know what you have or year, mine were in great shape and all mahogany.
I see you have started a thread on your boat, it's best to keep everything there in that one thread rather than splattering topics around on the same boat topic.
