Cold molding with thin strips

Hi Brian,
I wish there was a standard way to draw diagrams on the net. I'm not
quite sure if I've understood correctly. Do you mean that the first set
of ribs would be mainly vertical (for a "conventional bathtub", they
would look like U's), and the second set would be longitudinal? ie, a
see-through grid of ribs. If so, would you recommend attaching a
sheathing of thin ply before applying the glass skin?
Also, by 2 inches, do you mean the width of the ply strips?
Sorry if I'm missing the obvious, I haven't yet learned much about boat
building, and probably don't see some of the things that are clear to
others.
This is a speculative idea, rather than the fruit of long experience.
Yes I am thinking of ply ribs in two directions at right angles,
Whose faces are all vertical, so that in plan view, they would look
a noughts n crosses game of lines say 1/4 in thick, and in side view
they would be 2 inches deep and wide (at the sides.)
An internal and external skin would then provide a strong stiff light
structure. The crucial detail is making the inside skin fair and
smooth. This is left as an exercise for.... :-)
