: (I realize I was unclear) Comparing bending strength for equivalent weights,
: I.e., bare plywood is as good as ligheter plywood with glass.

: For a wooden kayak glass is necessary to provide strength across the grain.
: The water protection is also necessary.

George,
Are you saying that a laminate, say 5mm thick of wood, (plywood) will have equiv. strength to a laminate of 3mm plywoon and 2mm glass/epoxy?
