Chuck.
Please stop at "I'm not an engineer."
You are correct in the window muse. The design
does add to overall deck stiffness which
contributes to structure stiffness. This is not
to be confused with increased righting moment by anyone, I hope.
Regarding floorboards, do you mean the sole or
the floors? And by stiffening the design, do you
mean "She can carry more sail with this
improvement!" (the aforementioned right moment) or a less springy sole?
There are far too many areas to list in weight
saving activities before considering a move to an aluminum honeycomb sole.
I ask not facetiously but because Amazing Grace
has Kevlar reinforce floors and a normal teak &
holly plywood sole. This boat was a "no expense
spared" racing machine in the early 80s, to show
they had it figured out way back when.

I'm not an engineer but I do re-engineer many systems they dream up.
I think the fixed windows do add strength and
without them the structure has to be weaker.
They help support the coachroof which does
create an arch between the flatter deck sections.
Also, floorboards. You might stiffen up an old
design by changing from wooden plywood to an aluminum honeycomb sandwich.
But would the cost be worth it? Probably not
unless you needed to replace them.

Dwight â if I might jump in here, my
understanding is that the glued-in acrylic ports
became a unified part of the cabintop structure,
and stiffened the structure; NOT that they made
the boat stiffer in terms of sailing characteristics.

Is it really true that the designers at C&C
expected glued on acryllic ports to stiffen the whole boat
