Interesting!

The plate was drilled so there are lots of holes there and thickened epoxy used to build fillets before glassing over fills these holes. This would increase surface area and give improved mechanical strength. Comparable to embedding a bolt in epoxy.
Would this change your opinion or is this also done in the "standard but bad" way you mentioned?



For the chainplates we went for carbon chainplates glued to the hull. Stainless was to hard to work with.
