I sure hope I don't get a war of words going, but I would like get some
recommendations on which sheet material to use for our sliding main
hatch: polyacrylate (Plexiglas, Lucite, Acrylite, Perspex, etc.) or
polycarbonate (Lexan).

I'd go with hard coated polycarbonate. This is PC with a specially hardened
surface that doesn't scratch as easily. Most businesses that sell sheet PC
or acrylic will have the hardcoated material too.
