Removed my deck

I would think this would have to be the case vs the ease of just glassing a couple of large sheets of ply. Even if they were getting the ply wood scraps for free I don't think they would be saving.

When you get water intrusion from a screw hole in parquet it ruins 1 square. When you get water intrusion from a screw hole in a sheet of plywood it eventually ruins the whole sheet.

X2 When I redid the underside of my deck on my V21 I used as much scrap plywood as I could find, for that very reason. (I was counseled by my friend that owns a marina and knows these sort of things). His advice was pretty much what Skunk just said.. don't use full sheets, use pieces instead, as it will be stronger and last longer. And don't forget...SEAL the underside before you button it up, and VENT it with hatches open when it's stored.

I understand the theory of using multiple squares but thats only possible if you have an intact surface to lay them out on,my deck had already had the center section removed by a previous owner to allow a poor stringer fix,or if you pull the whole cap and turn it upside down.
I would also imagine you would need around 3-4 extra gallons of resin if you construct the deck in that manner.
I sealed the underside of my sheeting with resin and 3/4 oz CSM.

Looking good. While the small square theory is sound, there is nothing wrong with whole sheets, especially in resto situations where there is no backing to lay the squares. As long add the under side is sealed with CSM you'll be good to go.

Actually, you don't want to use squares. or even rectangular pieces. Irregular pieces work best. The idea is to not have any parallel running seams like you would get with same sided pieces. That way there's no weak spots, I know we're getting picky, but the very best way is curved pieces, (like the curves in the letter "S"). They are the strongest.

Here is the glassed in Deck. I had to build up the saddle tank platforms due to the raise in deck height,to prevent water sitting under the tanks per the original design.
It needs a little sanding here and there and then fairing.

looks solid, i'd gelcoat it, throw some splatter on it and go fishing
