You could also install some brass or SS sleeves in the holes for the engine mount bolts to help carry the crush loads.
Don's right about the I-beam concept for cored construction. Equal laminate thickness on each side of the core would create maximum stiffness, but I suspect most boat builders are inclined to cut corners and reduce cost on thickness of the inside laminate!
