That works of course, but there are other ways. Drilling an over size
hole, coating exposed core with epoxy resin, refilling with solid
glass, and then redrilling is a perfectly acceptable method of
ensuring core integrity and absorbing compression loads.

Sure, but you have to do that yourself. I thought we were talking about fromt the
factory.

Uh, and use a backing plate. Even better, build the backing plate into the
hull in place of the core in that spot.

But if it's in the center, it's not a backing plate
It has to be underneath both the tension & compression skins of the deck structure.

I read a description of an uncored but very light & strong boat hull, which had a
"subimposed" structural grid. Anybody have any good ideas what that means?
