I agree with your plan. Work from aft and leave the forward skin in place. I would be highly suspicious of any stainless bolts that went through wet core. I actually think it would be a 50/50 shot between the glass ripping off the hull and crevice corrosion making the bolts let loose. Biggest pain right now might be cold weather and epoxy.

Plus it would be very difficult to clean out and grind clean where the old core has to come out. The Chain Plate itself is on the bow side, therefore the higher forces are there as well. I want the core solid and well bonded to help re-inforce it. I'll probably keep the skin that I cut away, clean it up, and glass it back in afterwards as, like you say, using the bolts to hold it all together will distribute the pressure while it cures. Thanks for the fillets tip - I will definitely do that. I'm going to talk to Paul (our local glass expert) before I do anything just to get his two cents but I'm fairly confident this will work. I helped out with another boat where chainplates were being glassed directly into the hull with fresh glass and it's amazingly strong. If done properly, the tabs shouldn't fail.
